Description

Emulsifying cosmetic composition containing no emulsifier

The present invention relates to an emulsifier-free emulsifying cosmetic composition that can maintain the emulsification stability even at the same time without containing an emulsifier.

Cosmetics are used as a means to protect, recover and maintain skin from the external environment. In addition, it has the function of replenishing the moisture and oil of skin lost by daily washing and delaying skin aging.

Emulsification used to produce a cosmetic having such a variety of functions do not agglomerate the aqueous liquid phase and the oil phase liquid particles, and requires an emulsifier to evenly disperse. The emulsifier is a molecule having a hydrophilic portion and a lipophilic portion at the same time, when contained in the emulsification, serves to lower the interfacial tension between the water phase and the liquid phase. As a result, dispersion is well performed, and the emulsion stability is increased.

However, the added synthetic emulsifier causes skin irritation or allergy. This emulsifier having an amphiphilic structure tends to solubilize the skin lipids to form micelles, which leads to damage of the lipids of the skin and weakening of the barrier, causing skin irritation and allergies.

In order to solve this problem, the interest in the use of natural emulsifiers composed of natural ingredients that can replace the existing synthetic emulsifiers has increased rapidly. For example, Korean Patent No. 10-0912242 discloses the use of lecithin as a natural emulsifier, which has excellent emulsification stability and has an effect of preventing skin irritation and allergy caused by using an existing synthetic emulsifier.

However, while the lecithin, which is a natural component, has excellent skin affinity, when contained as an emulsifier in a cosmetic composition, instability, discoloration, and discoloration at high temperatures occur, and there is a problem of being an expensive raw material.

Accordingly, the present inventors have made various efforts to prepare a cosmetic composition that maintains emulsion stability without containing a conventional synthetic or natural emulsifier. As a result, dipalmitoylhydroxyproline and tangerine dietary fiber are used as an active ingredient without an emulsifier. The present invention was completed by confirming that the emulsion stability was maintained.

Accordingly, an object of the present invention is to provide an emulsifier-free emulsifying cosmetic composition which can have an effect of improving skin while maintaining emulsification stability even without containing an emulsifier.

In order to solve the above object, the present invention provides an emulsifier-free emulsion cosmetic composition containing dipalmitoylhydroxyproline and tangerine dietary fiber as an active ingredient.

The emulsifier-free emulsion cosmetic composition of the present invention can maintain the emulsification stability and at the same time have a skin improvement effect, even without containing an emulsifier, it is possible to secure a high value as a cosmetic.

1 (a) and 1 (b) show changes in skin wrinkle improvement before and after application of the composition of Example 1 of the present invention.

Hereinafter, the present invention will be described in more detail.

The present invention provides an emulsifier-free emulsion cosmetic composition capable of maintaining emulsion stability even without containing a synthetic or natural emulsifier. The emulsifier-free emulsion cosmetic composition according to the present invention contains dipalmitoylhydroxyproline and tangerine dietary fiber as active ingredients, thereby maintaining emulsion stability.

Dipalmitoyl Hydroxyproline is manufactured by fusion of plant-derived hydroxyproline (Hydroxyproline) with fatty acid (palmitic acid). , Emulsion stability is maintained in the cosmetic composition of the present invention. As the cosmetic composition of the present invention contains dipalmitoylhydroxyproline as an active ingredient, it is possible to prepare a cosmetic composition having excellent emulsion stability without containing a conventional synthetic and natural emulsifier.

The dipalmitoylhydroxyproline is preferably contained in an amount of 0.05 to 5% by weight in the total emulsifier-free emulsion cosmetic composition according to the present invention. If the content of dipalmitoylhydroxyproline is less than 0.05% by weight, the effect of emulsification stability and skin improvement cannot be expected, and even if the content exceeds 5% by weight, there is no significant effect improvement and the stability of the formulation is deteriorated. Because it occurs.

Citrus Aurantium Sinensis (Orange) Fiber refers to dietary fiber obtained from the pulp of the tangerine tree. The tangerine fiber serves to form a fine network in the emulsifier-free emulsion cosmetic composition according to the present invention. As such a fine network is formed, emulsified particles can be stably formed, and the formed emulsified particles are stably maintained to form a cosmetic composition having emulsification stability.

Tangerine dietary fiber according to the present invention is preferably contained in 0.1 to 3% by weight relative to the total emulsifier-free emulsion cosmetic composition weight. This is because when the content is less than 0.1% by weight, the effect can not be expected, even if the content exceeds 3% by weight because there is no significant improvement in effect economic efficiency.

As described above, the emulsifier-free emulsion cosmetic composition according to the present invention simultaneously contains dipalmitoylhydroxyproline and tangerine membrane fiber as an active ingredient, thereby stably forming emulsified particles and stably maintaining the formed emulsified particles. Therefore, it becomes possible to manufacture an emulsifier-free emulsion cosmetic composition that is maintained in the long-term emulsion stability.

More specifically, the emulsifier-free emulsion cosmetic composition according to the present invention to satisfy the total composition 100% by weight,

A water phase part containing 5 to 20% by weight of polyol, 0.1 to 3% by weight of tangerine dietary fiber, and water,
