Description

Bath slime and its manufacturing method {BATH SLIME AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to bath slime and a method of manufacturing the same, and more specifically to a bath slime made of a fluid and sticky material and a method of manufacturing the same.

Recently, sticky toys in the form of hydrogel have been widely used, and are called by various names such as liquid monster, jelly monster, jelly monster, and flubber, but are generally referred to as slime.

There are several types of slime, for example, they can be made based on PVA.

PVA (polyvinyl alcohol) is a water-soluble polymer and is also called vinyl alcohol resin. It has a chain structure and is soluble in water.

When some of these PVA chains form hydrogen bonds with the borate ion (B(OH)4-) contained in borax, a network structure is created, allowing moisture to be trapped between the network structures, forming a more solidified colloid. It takes the form of a hydrogel and has increased elasticity, which is an example of slime.

Guar gum, a food additive, can also create slime by combining with boric acid ions, and it has a slightly different texture than when using PVA glue.

These slimes can be kneaded with your hands to create various shapes, and they are very popular with children because they like the sticky and slippery feel of the slime in their hands.

However, conventional slimes only focused on allowing people to create various shapes by kneading while sitting on a desk, and could not be used for showering or simple water play.

In particular, conventional slimes are industrial products, and many of the substances they contain are unsuitable for use with water play.

For example, depending on the product, phthalate, a chemical additive, may be used to gently process plastic. Phthalate is a presumed environmental hormone that can not only threaten the health of children, but also have a negative impact on the environment if discharged with water. You can.

However, in the case of young children, showering and bathing are often considered a form of play, and it is time to manufacture slime that can be used even when playing in water.

It may contain 2 to 6 parts by weight based on 100 parts by weight, and the thickener may be included in an amount of 0.8 to 3 parts by weight based on 100 parts by weight of the purified water.

As described above, according to the present invention, infants and children can safely enjoy slime while showering/bathing or playing in water.

In particular, the bath slime according to the present invention is composed only of cosmetic ingredients rather than industrial products, and provides slime's unique viscosity (stickiness) and slippery feeling, while also achieving a cleansing effect when showering or bathing.

In addition, the bath slime according to the present invention is completely dissolved in water, so there is no need to worry about a separate disposal method, and it can be flushed out with water after use in the shower or bath, which significantly increases user convenience compared to existing slimes.

Figure 4 is a diagram showing the actual dissolution process of foreign liquid slime for comparison with Figure 3.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Each embodiment according to the present invention below is only an example to aid understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention may be comprised of a combination of at least one of the individual components, individual functions, or individual steps included in each embodiment.

In particular, for convenience, alphabet letters such as '(a)' are included in some claims, but these alphabet letters do not specify the order of each step.

Slime according to an embodiment of the present invention includes a solvent, a viscous moisturizer, and a thickener.

Here, the solvent may include purified water, 1,2-hexanediol, butylene glycol, and propanediol.

Purified water is water from which all impurities such as dissolved ions, solid particles, microorganisms, organic matter, and dissolved gases contained in general water have been removed. For this purpose, methods such as ion exchange resin method, reverse osmosis filter, etc. can be used.

In particular, purified water does not contain metal ions such as calcium or magnesium, so the slime according to this embodiment may not easily contaminate or cause trouble to the human body.

1,2-hexanediol, also called 1,2-dihydroxyhexane, has a structure in which the first and second alcohol groups of a straight alkyl chain are attached to each other, and has a surfactant structure that has both hydrophobic and hydrophilic groups. It is an odorless substance.

It is highly soluble in water and emulsifiable in oil components, so it functions as a solvent to mix active ingredients that do not mix well in water within the formulation, but it also acts as a preservative to replace traditionally used parabens, and is EWG rated. This is a grade 1 safe product.

Furthermore, it also functions as a moisturizer and has a skin moisturizing effect.

It is preferable to add 1 to 3 parts by weight of these preservative ingredients based on 100 parts by weight of purified water.

Butylene glycol is an odorless, sweet liquid, a type of polyol that has two hydrophilic receivers, and is a natural ingredient obtained from fermentation products. It also functions as a solvent and is a skin moisturizer that attracts moisture. It also has an antimicrobial effect and acts as a preservative.

Propanediol is a natural ingredient extracted by fermentation from corn. It not only functions as a solvent, but also helps stabilize the emulsion of other ingredients.

The viscous moisturizer is preferably selected as an ingredient that plays the main role of providing the unique viscosity of the slime according to the present invention and does not have a negative effect on the skin, preferably as a moisturizer.

A viscous moisturizer contains a humectant that has a hydrophilic group and absorbs surrounding moisture, a film former that forms a skin film to block skin moisture evaporation, and a skin softener. It is preferable to use a humectant.

The humectant may include glycerin as a trihydric alcohol, sorbitol as a sugar alcohol, and further may include hyaluronic acid, gamma PGA, etc. as a high molecular weight polymer.

In this embodiment, the description will focus on the example of using glycerin.

Glycerin is a colorless, odorless liquid, a natural component of vegetable oil, and can be synthesized from substances such as carbohydrates (e.g., sugar cane or corn syrup sugar). It is approved by the US FDA, the US Cosmetic Ingredient Review Board, and the European Union. It is a safe substance that can be widely used in cosmetics, personal care products, food additives, and pharmaceuticals.

In particular, glycerin has relatively strong viscosity, which contributes greatly to the stickiness of the slime according to the present invention.

In this embodiment, the viscous moisturizer is preferably included in an amount of 2 to 6 parts by weight based on 100 parts by weight of purified water. In particular, when glycerin is used, it is preferably included in an amount of 3.5 to 5 parts by weight based on 100 parts by weight of purified water.

Meanwhile, the thickener functions to improve the viscosity, which is the main feature of the bath slime according to this embodiment, and includes sodium polyacrylate, carbomer, xanthan gum, polyacrylate, polyisobutene, It may be at least one of polysorbates.

The addition ratio of the thickener, along with the above-mentioned viscous moisturizer, is very important in giving the bath slime according to this embodiment a slippery and sticky feel. It is preferable to include 0.8 to 3 parts by weight based on 100 parts by weight of purified water.

In particular, when using sodium polyacrylate, which exists in white powder form as a sodium salt of polyacrylic acid among thickeners, it is most preferable to include 1 to 2 parts by weight based on 100 parts by weight of purified water.

In addition, the bath slime according to the present invention is used by children while playing in the water, and may be in contact with the skin for a long time, so it may further include an acidity regulator.

Acidity regulators, also called pH regulators, play a role in adjusting the pH of the final material.

Here, pH refers to hydrogen ion concentration and is divided into numbers from 1 to 14. Among these numbers, '7' is neutral, lower numbers indicate acidity, and higher numbers indicate basicity. The ideal human skin pH is 4.7~ At 5.75, it is in a slightly acidic state.

The pH of the skin is closely related to the skin condition, skin protective layer, and keratin condition, so when the skin becomes alkalized, it is easily damaged by external stimuli and is prone to troubles. Therefore, in the case of the present invention that is in direct contact with the skin for a long time, such an acidity regulator is used. This is to minimize skin irritation.

In other words, as mentioned above, when the pH of normal skin is maintained at a slightly acidic level of about 5.5, the oil and water balance of the inner and outer layers of the skin is correct, and the acidity is adjusted to form a good protective film to protect the skin from various bacteria and harmful environments. A regulator is added.

This acidity regulator may be selected from at least one of BHT, lactic acid, citric acid, etc., and is preferably added in an amount of 1 part by weight or less based on 100 parts by weight of purified water.

Meanwhile, the bath slime according to an embodiment of the present invention may further include a skin conditioning agent.

Skin conditioning agents broadly include ingredients that increase moisture retention in the outer layer of the skin, such as humectants, but in this embodiment, they increase collagen formation, revitalize the skin through skin regeneration effects, anti-inflammatory and soothing effects, etc. As one that performs the function, it may especially include centella asiatica extract and propolis extract.

Here, the centella asiatica extract is extracted from a plant called Centella asiatica. The extract acts by strengthening the connective tissue of blood vessels and increasing collagen formation, and has wound healing, skin regeneration, and anti-wrinkle effects. It also has anti-inflammatory and soothing effects.

At this time, the Centella asiatica extract was extracted by washing the aerial part of Centella asiatica thoroughly with distilled water, drying it at 50°C, pulverizing it with a grinder to powder it, adding ethanol to it, and soaking it at room temperature for about 3 hours, and then filtering the obtained extract. It can also be obtained by concentrating the filtrate under reduced pressure under vacuum.

Propolis is a mixture of resinous substances that bees collect from plants such as tree buds and sap. Propolis extract has antibacterial, antiviral, and anti-inflammatory effects, helping to manage free radicals and soothe sensitive skin. It functions to soothe and brighten the skin, remove substances harmful to the skin, and protect the skin from harmful oxygen.

Propolis extract can be extracted in a variety of ways, such as removing the wax from propolis made by bees mixing their own secretions with resin collected from plants, extracting it with water or alcohol, or extracting it using carbon dioxide.

There are various extraction methods, such as alcohol extraction, micellar extraction, supercritical extraction, water extraction, and mixed solution extraction of alcohol and water, and can also be extracted in the same manner as in Registered Patent No. 10-1952275.

Since the extraction method of the propolis extract corresponds to a known technique, a more detailed description is omitted.

In addition to the above-described ingredients, the bath slime according to an embodiment of the present invention may further include another skin conditioning agent such as ethylhexylglycerin, spinach extract, and Hwangchil tree extract, and may further include kelp extract as a flavoring agent.

Of course, each of the various components described above not only performs a single function but also has other complex functions.

For example, some solvents have a weak moisturizing effect and viscosity control effect.

However, the main role in the bath slime according to an embodiment of the present invention was mainly explained.

(Example 1)

Bath slime having the composition shown in Figure 1 was prepared.

The addition ratio below indicates the relative weight based on 100 parts by weight of purified water.

First, add purified water, 4.5 parts by weight of glycerin, 2 parts by weight of 1,2-hexanediol, 1.8 parts by weight of sodium polyacrylate, and 0.6 parts by weight of citric acid in a mixing container and heat to 70°C while stirring, then stir for 35 minutes. Cool to °C.

Afterwards, 0.15 parts by weight of centella asiatica extract as a skin conditioning agent, 0.0002 part by weight of spinach extract, 0.0002 part by weight of kelp extract, 0.0015 part by weight of propolis extract, 0.15 part by weight of ethylhexylglycerin, 0.002 part by weight of butylene glycol as a solvent, and propane die. Add 0.001 parts by weight of allergen and heat to 65°C while stirring, then cool to 30°C and age for 4 to 5 hours.

At this time, additional additives to express color may be added, but this is omitted.

(Comparative Example 1)

The same procedure as in Example 1 was carried out, but 3 parts by weight of glycerin was added.

(Comparative Example 2)

The same procedure as Example 1 was carried out, except that 1 part by weight of sodium polyacrylate was added.

(Comparative Example 3)

The same procedure as in Example 1 was carried out, but 6 parts by weight of glycerin was added.

(Comparative Example 4)

The same procedure as in Example 1 was carried out, except that 3 parts by weight of sodium polyacrylate was added.

<Sensory evaluation of Example 1 and other comparative examples>

1. Experimental method

1) Sensory evaluation

The bath slimes produced by the above-described examples and comparative examples were used by infants and children aged 5 to 13 years old when showering/bathing and playing in the water under parental control, and were administered to 100 people who clearly expressed their preferences. An evaluation was conducted.

The grading criteria are very good; 9 points, neither like nor dislike; 5 points, strongly dislike; It was set as 1 point.

The sensory evaluation results for each bath slime are shown in Figure 2.

Figure 2 shows the results of a survey on the inherent viscosity of the slime, that is, the preference for the degree of elongation and the preference for the slippery feeling.

First, when a small dose of glycerin was administered as in Comparative Example 1, the inherent viscosity effect of glycerin was reduced, resulting in a decrease in both viscosity preference and slipperiness preference.

In addition, when a small dose of sodium polyacrylate was administered as in Comparative Example 2, the viscosity itself in the liquid was significantly lowered, and only a slight difference could be felt compared to water. As a result, the viscosity preference was significantly lowered, and the slipperiness preference was also lowered. The result was lower than that of Comparative Example 1.

Looking at the results of Comparative Example 1 and Comparative Example 2, it can be seen that when the dosage of viscous moisturizer and thickener is reduced, many of the unique characteristics of slime disappear, resulting in a significant decrease in preference.

And when the glycerin dose was further increased as in Comparative Example 3, the viscosity preference and slipperiness preference increased significantly, unlike other comparative examples, but did not reach the results of Example 1.

In addition, when the thickener dosage was increased as in Comparative Example 4, the viscosity preference was lower than that of Comparative Example 3, and the slipperiness signal was also significantly lowered.

Looking at the results of Comparative Example 3 and Comparative Example 4, although the bath slime according to Example 1 has lower viscosity compared to the existing solid slime, it is better to use it with shower / bath or water play. It can be seen that the viscosity of slime is more preferred.

In other words, although the viscosity of the bath slime according to Example 1 is lower compared to the existing solid slime that can create a liquid monster, when used with shower/bath or water play, the fluidity of the slime with flowing water is low. Only when this happens will users’ preferences increase.

If the viscosity of slime used with shower/bath or water play exceeds a certain threshold, it will have an adverse effect.

In addition, Figure 2 includes measurements of the time for the slime produced according to Example 1 and each comparative example to dissolve in water.

The measurement method is to adjust 1 liter of water to the bath water temperature of 35 degrees, add 100 ml of slime solution, mix by hand for 5 seconds, and measure the time it takes for the slime to completely dissolve in the water without clumping.

As expected, the smaller the amount of viscous moisturizer or thickener, the shorter the dissolution time. In particular, in Comparative Example 3 and Comparative Example 4, it was delayed by 5 to 10 seconds compared to Example 1.

This dissolution time may be further delayed when the amount of slime used is large, and therefore, it can be seen that the slimes according to Comparative Examples 3 and 4 are not suitable when rapid processing and leaving no residue are important.

Meanwhile, Figures 3 and 4 compare the degree of dissolution of the bath slime according to the present invention and foreign liquid slime.

Figure 3 shows the state after putting the bath slime according to Example 1 in water (Figure 3(a), Figure 3(b)), stirring it by hand for 5 seconds (Figure 3(c)), and leaving it for 10 seconds (Figure 3) 3(d)) is shown step by step.

As shown in Figure 3, it can be seen that the bath slime according to Example 1 is completely dissolved within 10 seconds simply by adding it to water and stirring it.

Figure 4 shows the state after putting foreign liquid slime in water (Figure 4(a), Figure 4(b)), stirring it by hand for 5 seconds (Figure 4(c)), and leaving it for 1 minute (Figure 4(d) ) is shown step by step.

As shown in Figure 4, foreign liquid slime is placed in water, stirred by hand, and left for more than 1 minute (longer than 10 seconds in Figure 3), but it still does not completely dissolve and clumps together.

In the case of liquid slime that can be used with bathing, the post-use treatment process is also very important. However, when the slime is designed to easily dissolve in water, as in the present invention, it can be drained along with water, increasing convenience in use.

In particular, if the liquid slime is not completely dissolved in water as shown in Figure 4, it may stick to drain pipes, etc. and contaminate them, which may lead to limitations in use.

In addition, as can be seen by looking at the ingredients in Figure 1, the bath slime according to the present invention is composed only of cosmetic ingredients that can be used harmlessly to the human body, rather than industrial products, so that infants and children can use it safely while playing in the water, and furthermore, it can be used as a cleansing agent. By performing both functions, you can kill two birds with one stone.

In other words, when you place the bath slime according to the present invention on your hand and rub it with water, foam is generated and a cleaning effect is achieved.

In particular, the bath slime according to the present invention contains toys that are common industrial products such as silicone oil, mineral oil, CMIT/MIT, triethanolamine, benzophenone, PEG, animal raw materials, triclosan, talc, 6 types of parabens, phenoxyethanol, and sulfate. By not using any of the many ingredients, you can protect your children's health while still allowing them to enjoy the unique play of slime.

The present invention is not limited to the specific embodiments described above, but can be implemented with various changes and modifications without departing from the gist of the present invention.

In particular, it goes without saying that the present invention can be enjoyed not only with a bath but also with various types of water play.

It will be apparent that such changes and modifications are included in the present invention if they fall within the scope of the appended claims.
