Abstract

The present invention relates to a cosmetic composition prepared by combining a cellulosic-based polymer compound and an acrylate-based polymer so as to have a solid yogurt texture, and more particularly, to a cosmetic composition that have a smooth and elastic appearance with solid yogurt texture and may improve the drawback of dripping phenomenon in the conventional cosmetic composition having yogurt texture while apply to the skin to impart a moisture feeling.

Description

Yogurt cosmetic composition

The present invention relates to a cosmetic composition having a solid yogurt texture produced by combining a cellulose-based high molecular compound and an acrylate polymer, and particularly relates to a cosmetic composition having a solid yogurt texture A cosmetic composition that has a smooth and elastic appearance, imparts a moisturizing feeling when applied to the skin, and improves the dripping phenomenon of conventional yogurt-based cosmetic compositions.

In general, film (pack) is the main cosmetic that makes the skin healthy and beautiful by supplying moisture to the skin, moisturizing effect that locks in moisture, cleansing effect that absorbs and removes skin pollutants, and promoting blood circulation, etc., long ago Just start using it. The film cosmetics are not only for the face, but can also be used locally or for the whole body such as the neck, shoulders, arms, legs, etc., and can be manufactured as a tear-off type (peel) used in gel, paste, or powder. -off-type), tissue-off-type (tissue-off-type) used as cream, clay, gel, aerosol, wash-off type (wash-off-type), peel-off type that peels off after curing, Forms such as non-woven gel, non-woven impregnated coating type, etc. Each has its own advantages and disadvantages, so the researchers who make the preparation select a dosage form with a suitable form according to the preferences of each consumer, and improve its disadvantages.

Most of the film cosmetics except the non-woven fabric application form a temporary film on the face to prevent the inflow of external air or the evaporation of water, and polyvinyl alcohol and polyvinyl pyrrolidine are used as film agents Polymer compounds such as ketone, hydroxyethyl cellulose, carboxymethyl cellulose, vinyl acetate emulsion, xanthan gum, carboxyvinyl polymer, etc. However, the above-mentioned film cosmetics are poorly soluble substances, are not easy to wash off after drying, and have a problem of irritating the skin due to physical stimulation when peeled off.

In addition, the skin moisturizing effect of cosmetics is the basic effect that cosmetics should have. Therefore, humectants are used in the composition of film cosmetics to improve the moisturizing effect. However, when using a moisturizer to improve the moisturizing effect, a large amount of the moisturizer needs to be used, and when applied on the skin, a film cannot be formed normally, and there is a problem that the adhesive force and the fit feeling are reduced.

Therefore, in the existing various types of film cosmetics, it is necessary to develop a new film cosmetic, which can improve the application force and docile feeling during use, and can be easily washed with water, so that it can reduce physical stimulation and skin irritation. At the same time, it improves the moisturizing effect.

Cosmetics in film dosage form containing functional substances are manufactured by adding water or lotion or functional extracts to non-woven fabrics and other supports, and adding lotion or functional extracts to non-woven fabrics and other supports Sometimes, there is a problem of hardening or poor usability. Further, natural or animal proteins such as collagen, silk, silk protein, etc., are difficult to handle due to their weak strength, and are more sensitive to temperature, so it is difficult to form a gel at room temperature or freeze-dry them. In addition, there is a problem because it is a high-priced product. In addition, the form of a cosmetic film takes a considerable amount of time to dry to form a film after application, so it is difficult to sufficiently penetrate the cosmetic agent into the skin in a short period of time, and it needs to be removed.

On the one hand, curdled yoghurt-type film composition imparts a moisturizing feeling to the skin and is often used as a skin external preparation or cosmetic composition due to its soft texture. Conventional products with a texture are less favorable due to their peculiar odor, and when used directly on the skin, there is a problem of severe dripping and inconvenience (refer to Patent Documents 1 and 2).

Against this technical background, the present inventors developed a cosmetic composition that, when applied to the skin, imparts a moisturizing feeling and improves the dripping phenomenon of conventional curdled milk yoghurt textured cosmetic compositions. As a result of this effort, it was confirmed that cetyl hydroxyethyl cellulose, which is a cellulosic polymer compound, and hydroxyethyl acrylate/acryldimethyl taurine, which is an acrylate polymer, are contained in an appropriate weight ratio. A cosmetic composition of a sodium copolymer has a solid yogurt-like smooth and elastic appearance, and when applied to the skin, it imparts a moisturizing feeling and improves the dripping phenomenon, thereby completing the present invention.

When the content of raw gum exceeds 1.0% by weight, there is no significant increase in the effect, but only the odor of xanthan gum is increased. Therefore, it is preferable to use it appropriately within the above range.

Evaluation criteria:

①Excellent appearance and texture: the surface is elastic (resilience to the original shape), smooth, and has very good grasping properties (very similar to the appearance and texture of solid yogurt).

② Good appearance and texture: the surface is slightly elastic (resilience to the original shape), slightly smooth, and slightly gripping (slightly similar to the appearance and texture of solid yogurt).

③Poor appearance and texture: the surface has no elasticity (resilience to the original shape), is not smooth, and has poor grip (it is not similar to the appearance and texture of solid yogurt).

As a result, as shown in Table 3 and Table 4 below, the appearance and texture state of the compositions of Examples 1 to 4 and Comparative Examples 1 to 12 are different from each other to such an extent that they can be compared with the naked eye/touch.
