Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides the same properties and feel as lanolin when used, and is suitable for use in general cosmetics such as skin care cosmetics, hair care cosmetics and makeup cosmetics. Is.

[0002]

2. Description of the Related Art Conventionally, lanolin has properties such as crystallization prevention of wax, water retention, emollient property, imparting high gloss and the like, and since it has a fatty acid composition similar to the lipid outside the hair, make-up, It has been widely used in skin care, hair care cosmetics, etc. However, in the recent movement toward non-animal-based raw materials, raw materials to replace lanolin are required. However, although it is possible to substitute the lanolin's individual characteristics in the conventional lanolin substitute raw material, there is no substitute raw material that simultaneously satisfies various characteristics of lanolin, and a plurality of raw materials are blended in the formulation to give a lanolin-like feel. Has been considered to give but not enough.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the drawbacks of the conventional lanolin substitute cosmetic raw material and to provide an excellent cosmetic having a lanolin-like feel.

[0003]

As a result of various studies, sucrose tetraisostearate ester and fats and oils are used in a combination of 0.01 to 50% by weight, or sucrose tetraisostearate ester and fatty acid are used in combination. The inventors have found that the combined use of each of the esters in an amount of 0.1 to 50% by weight gives lanolin-like properties and feel, and completed the present invention. That is, according to the present invention, without using a complicated prescription by using the above combination,
It is possible to give lanolin-like properties, touch and feeling to the cosmetics, and facilitate lanolin substitution in various cosmetics in which lanolin has been conventionally used.

BEST MODE FOR CARRYING OUT THE INVENTION The constitution of the present invention will be described in detail below.

Sucrose branching used in the present invention (C8-C2
0) Fatty acid ester is one of the eight hydroxyl groups of sucrose
All or all of them form an ester with a branched (C8-C20) fatty acid, and as the branched (C8-C20) fatty acid, isostearic acid can be preferably exemplified. The degree of esterification is 1, 2, 3, 4, 5, 6,
Either 7 or 8 is possible, but 4 from the viewpoint of physical properties.
Is particularly preferable. The fatty acid to be esterified is branched (C
8 to C20) One or more selected from fatty acids may be composed of only two or more kinds, and linear fatty acids and hydroxy fatty acids, C21 or more linear or branched fatty acids, and C9 or less linear or branched fatty acids. May be included.
Most preferably, it is composed only of branched fatty acids, and more preferably it is composed only of branched (C8-C20) fatty acids. Such a sucrose branched (C8-C20) fatty acid ester uses sucrose and a branched fatty acid methyl ester as a solvent in dimethyl sulfoxide or the like,
It can be obtained by reacting with potassium carbonate or the like as a catalyst, neutralizing the catalyst, recovering the solvent under reduced pressure, and purifying with activated carbon or the like. During this esterification reaction,
By changing the stoichiometric ratio, an ester having an arbitrary ester value can be obtained as the main component. The sucrose branched (C8-C20) fatty acid esters thus obtained are all compounds not described in the literature. These sucrose branches (C8-C20)

The oils and fats used in the present invention include shea butter, theobroma grandiflorum seed fat, cocoa butter,
Macadamia nut oil, safflower oil, tea oil, camellia oil,
Evening primrose oil, southern oil, olive oil, meadowfoam oil, almond oil, avocado oil, peanut oil, sesame oil, soybean oil, wheat germ oil, coconut oil, borage seed oil, kyounin oil, jojoba oil, hazelnut oil, rosehip oil, etc. Is. This oil / fat can be obtained by refining the oil / fat obtained by extracting or oiling seeds or fruits. The preferred content of oils and fats in the cosmetic of the present invention is 0.1 to 50% by weight in total.

The fatty acid ester used in the present invention has a carbon number (C8-C36) in the fatty acid component (C8-C36).
It is an ester obtained by reacting the aliphatic alcohol of 22). In the cosmetic of the present invention, the total content of fatty acid esters is preferably 0.1 to 50% by weight.

The cosmetic composition of the present invention may contain any of the components commonly used in cosmetics, within a range that does not impair the effects of the present invention. Examples of such optional components include waxes such as beeswax and carnauba wax, hydrocarbons such as petrolatum and microcrystalline wax, beef tallow, olive oil, triglycerides such as shea butter, cetanol, and oleyl alcohol. Higher alcohols, fatty acids such as stearic acid and oleic acid, UV absorbers such as octyl methoxycinnamate, UV inhibitors such as titanium oxide, polyhydric alcohols such as glycerin and 1,3-butanediol, nonionic surface active agents Preferred examples include agents, anionic surfactants, cationic surfactants, amphoteric surfactants, ethanol, thickeners such as phosphoric acid esters and xanthan gum, carbopol, preservatives, antioxidants, pigments and the like.

The use of the present invention includes skin care cosmetics,
It can be used to impart lanolin-like properties and feel to cosmetics in general such as hair care cosmetics and makeup cosmetics.

EXAMPLES The present invention will be described more specifically by way of examples. The invention is not limited to these examples only. All compounding amounts are% by weight.

Example 1 Each item was evaluated by adjusting the lip gloss formulation shown in Table-1. As a result of being evaluated by 10 panelists, the gloss and the feeling of use were also excellent. From these results, a good lip gloss formulation was obtained by combining sucrose tetraisostearate and oils and fats or fatty acid esters. In comparison with a formulation (comparative example) using polybutene that has been conventionally used as a lanolin substitute raw material, the combination of sucrose tetraisostearate and oils or fatty acids was excellent in feel and luster. In addition, it was found that there was no difference in gloss and feeling of use when compared with the formulation using liquid lanolin (Comparative Example), and it was confirmed that it can be used as a lanolin substitute raw material.
