Abstract

The present invention provides a stick formulation cosmetic composition, and a manufacturing method thereof, wherein the stick formulation cosmetic composition comprises porous powder supported with at least one selected from the group consisting of volatile oil and functional water-soluble components.

Description

[0001] The present invention relates to a stick-form cosmetic composition containing a porous powder and a preparation method thereof,

The present invention relates to a stick-shaped cosmetic composition comprising a porous powder and a method for producing the same.

Ultraviolet rays are attracting attention as the main cause of exogenous aging which causes skin cancer and the like. As a result, the domestic cosmetics market for UV protection has grown rapidly every year. In recent years, UV-blocking transparent stick-like products having characteristics such as convenience, durability and water resistance have gained popularity, and they have a disadvantage of having an oily feeling and a feeling of being stout and sticky.

When the powder is used to offset such feeling, there is a problem that the transparency is lowered. In addition, although nano-sized silica is used, there is a disadvantage in that when added in an excessive amount, the feeling of feeling peculiar to silica is manifested and the dispersion is not easy and the quality is deteriorated.

The inventors of the present invention have completed the present invention as a result of intensive research to improve the feeling of use or transparency of the transparent stick cosmetic composition including the ultraviolet shielding stick cosmetic composition.

In general, cosmetics of stick form have to be subjected to a high-temperature dispersion process at a temperature of 100 ° C or higher in the nature of their production, so that oils having a boiling point of about 70 ° C can not be added. In order to maintain transparency, The invention solves this problem by supporting a volatile oil and / or a functional water-soluble component in the porous powder.

Experimental Example 1. Post-production weight loss test

Examples 1 and 2 The weight loss test was conducted in the course of preparing Comparative Examples 1-3. The test method was calculated as weight after production (g) / weight of feed (g) × 100, and the results are shown in Table 2

division Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 Weight loss ratio (%) 0.08 0.10 3.82 3.56 0.07

As shown in the above results, in Examples 1 and 2 of the present invention, the weight loss was equivalent to that of Comparative Example 3 in which no volatile oil or water-based raw material was added. However, Examples 1 and 2 are believed to have mostly evaporated volatile oils and water-soluble components.

Experimental Example 2. Confirmation of transparency of stick formulation

As shown in [Figure 3], the transparency of the stick-shaped cosmetic compositions according to Examples 1 and 2 of Comparative Examples 1 to 3 was compared. In Examples 1 and 2 and Fertilizer Example 2, translucent stick formulations were obtained, and in Comparative Examples 1 and 2, opaque stick formulations were formed. Therefore, it was confirmed that when the method of the present invention was used, transparency was maintained even when a large amount of porous powder was added.

Experimental Example 3.

Examples 1 and 2 Comparative Examples 1 to 3 were packed in a stick container and then applied to the face before and after applying to the face using a facial skin scanner machine (Facial Skin Scanner Machine S / 12907584). After 3 hours and after 6 hours, Were measured.

As shown in FIG. 4, in the case of Example 1, the amount of sebum was decreased by 59.6% immediately after application and increased from 102.0% after 6 hours to 156.0% after 6 hours. Example 2 showed similar results to Example 1 immediately after application and 3 hours after application, but the amount of sebum rapidly increased after 6 hours and increased by 200%, which is similar to Comparative Example 1. In Comparative Examples 1 to 3, sebum reduction was small similarly to non-douche immediately after application, and in Comparative Example 3, the sebum amount rapidly increased after 6 hours to 300%. As shown in the above results, the amount of increase of sebum tended to be decreased compared to non-dandruff, and Example 1 showed the most effective suppression of sebum. It is believed that the sebum generated from the skin adsorbs in the porous powder as the volatile oil evaporates.

Experimental Example 4. Measurement of Number of Pores

Examples 1 and 2 Comparative Examples 1 to 3 were filled in a stick container, and images were taken using a facial skin scanner machine (S / 12907584) before and after application, and then the number of pores was quantitatively analyzed.

division Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 Number of pores (%) 100.0 48.0 69.7 98.7 99.5

As shown in Table 3, the pore cover effect of 50% or more was exhibited in Example 2, and the cover effect of 30% or more was also exhibited in Example 2. However, in Comparative Examples 1 to 3 produced by the general stick manufacturing method, It is not.

Experimental Example 5. Sensory Evaluation

30 female panelists aged 25-45 were divided into two groups, and Examples 1 and 2 and Comparative Examples 1 and 3 were appropriately adjusted to each group to be used on both sides of the face. Then, according to the following evaluation criteria, The sensation of feeling such as stickiness, adhesion, makeup picker ability, and overall satisfaction were evaluated, and the results are shown in Table 4 below.

Among the above criteria, stickiness refers to the property of softening to the skin due to the oily feeling remaining after spreading on the skin, and as the stickiness is less, it is a cosmetic suitable for the suncare cosmetic. Adhesion refers to a feeling of sticking to the skin when the composition is applied thinly on the surface of the skin when applied to the skin. The makeup picker function refers to the degree of consistency and the degree to which makeup is not pushed when applying base makeup such as foundation after applying stick formulations. These criteria increase the value of cosmetics and can be an important feature of cosmetics with ultraviolet blocking properties.
