Description

Silicone emulsifying type water soluble gel cosmetic composition with excellent sebum control and makeup lasting

[Industrial use]

The present invention relates to a water-soluble gel cosmetic composition for controlling sebum, and more particularly, to keep the skin clean by delaying and absorbing the diffusion of sebum secreted into the skin, including silicone and silica, to provide a fresh and lasting color cosmetic. Inducible silicone emulsifiable water soluble gel cosmetic composition.

[Prior art]

Sebum consists of approximately 60% triglyceride and fatty acid, 25% wax ester and 15% squalene, which is released from sebaceous gland and prevents evaporation of moisture. It gives humidity and flexibility to each layer, prevents invasion of harmful substances and bacteria from the outside, and prevents the release of substances such as moisture from the body. As such, sebum has a beneficial role in the human body due to its antibacterial effect, but sebum that is secreted in excess can not only cause acne and skin defects, but it also disturbs the makeup state and maintains the makeup's persistence and makeup state in color makeup. It acts as an important deterrent. Therefore, research into cosmetic formulations aimed at suppressing sebum secretion or removing secreted sebum has been actively conducted, and currently reported patents and literature are actually oils composed of water-soluble gels, silicone gels, and oil-absorbing powders. Various formulations, such as cakes, provide a sebum control effect and suggest a method of inducing clean makeup. However, these formulations have many disadvantages such as stickiness, oiliness, and slippery in terms of usability, and the effect is very insignificant in terms of sebum control.

Since the general water-soluble gel formulation is composed of water-soluble polymers such as carboxyvinyl polymer, carboxymethyl cellulose sodium, and the like, a lot of sticky feeling appears, and sebum control effect by these polymers is hardly expected. Therefore, in order to compensate for these drawbacks, a formulation for dispersing a silicone oil or a silicone polymer in a water-soluble gel formulation to supplement the finishing feeling and using a small number of silicone properties, a sebum control effect and a cosmetic effect has been developed. US Pat. No. 5,626,853 introduces a make-up gel prepared by mixing a silicone polymer using a carboxyvinyl polymer, carboxymethyl cellulose sodium, or the like as a water-soluble polymer. This formulation has softer and fresher advantages in terms of usability than general water-soluble gels, but has a problem in that it has a poor ability to inhibit or remove sebum secreted continuously. U.S. Patent No. 5,380,528 introduces a formulation that provides a unique feeling of use and an emollient effect by keeping the face fresh by controlling excessive secretion of sebum on the face. The formulation combines water-soluble polymers, moisturizers, silicone oils, silicone polymers and fluorine-based silicones to emphasize sebum control, moisturizing and clean make-up. In addition, U.S. Patent No. 5,589,165 introduces a formulation that combines silicone and a silicone polymer to induce clean makeup by supplementing the persistence and water resistance of the makeup, but this formulation is an oil-saturated formulation. Good but has a disadvantage that the makeup can be disturbed by sebum sebum inside the silicone film.

Sebum secreted on the face as described above reduces the persistence of the makeup acts as an absolute disadvantage to clean makeup. The suppression of sebum secretion by medical approach can enhance the cosmetic effect, but since the anti-inflammatory action given by proper sebum has a great effect on the human body, the sebum secretion is properly delayed and secreted rather than inhibiting sebum secretion itself. It is more efficient to control the

The present invention is to solve the problems of the prior art as described above, the object of the present invention is to feel smooth and fresh and excellent sebum control ability, to maintain the clean and fresh condition of the face and increase the persistence of makeup It is to provide a water-soluble gel cosmetic composition.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a silicone emulsified water-soluble gel cosmetic composition comprising a porous porous spherical silica, an acrylate / acrylamide copolymer, volatile and nonvolatile silicones, humectants and emulsifiers.

Hereinafter, the present invention will be described in detail.

The term "sebum control" can be defined as two meanings, such as inhibiting sebum secretion itself and removing sebum secreted along with delayed sebum secretion, in view of the benefits of suitable sebum in the present invention " The term "sebum control" was used to define the effect of delaying the skin diffusion of secreted sebum and removing excess secreted sebum.

The water-soluble gel cosmetic composition of the present invention comprises a porous porous silica, an acrylate / acrylamide copolymer, volatile and nonvolatile silicones, moisturizers and emulsifiers, and especially volatile and nonvolatile silicones and mesoporous spherical silica for sebum control It is characterized in that it is used, and each is used to adjust sebum in two ways.

First, emulsifying volatile and nonvolatile silicone to form a breathable silicone emulsion film on the skin to delay and block the release of secreted sebum on the skin surface to increase the persistence of makeup. In addition, such silicone oil has high water repellency, has a light usability without stickiness such as hydrocarbon oil components, and exhibits excellent spreadability to skin or hair. As the nonvolatile silicone oil, dimethicone having a viscosity of 5-20cs or methylphenylpolysiloxane having 50-100cs or the like can be used alone or in combination of two or more thereof, and the compounding amount thereof is 1.0-10.0% by weight. As volatile silicone, cyclomethicone (Dow Corning Co., Ltd.) or the like may be used, and the compounding amount thereof may be 1.0-15.0 wt%. The blending ratio of the volatile silicone and the nonvolatile silicone is used in the range of 60-90: 10-40 by weight.

Secondly, by mixing a large amount of mesoporous silica and uniformly dispersing it, it effectively absorbs sebum, which is a porous porous spherical powder, which has a significantly higher oil absorption than other powders, effectively maintaining a fresh and clean face. . Silica uses 1.0-15.0% by weight relative to the total weight of the composition.

The water-soluble polymer used in the present invention is an acrylate / acrylamide copolymer, and the acrylate / acrylamide copolymer is easily adjusted in viscosity in a small amount, and does not require a neutralization process such as carboxyvinyl polymer, and is light and fit without stickiness or slipperiness. It has a characteristic of being applied to the skin. In addition, the use alone can exhibit time-lapse stability, viscosity control, and feeling sufficiently over time, thus exhibiting different functions from other polymers. The water-soluble polymer is used in an amount of 0.1-3.0% by weight based on the total weight of the composition, and may be used in combination with carboxymethyl cellulose sodium.

As the emulsifier used in the present invention, a silicone-based emulsifier is mainly used. Examples of the emulsifier include dimethiconol, dimethicone copolyol, or silicone glycol copolyol having a HLB (Hydrophile-Lipophile-Balance) value of 5.0-13.9. Preferably, the HLB value is in the range of 3.0-8.0, and at least one compound selected from the group consisting of silicone glycol copolymers, laurylmethicone copolyols, cyclomethicones and dimethicone copolyols may be used. The amount of these compounds is 0.2-3.0% by weight relative to the total weight of the composition. When the amount of these compounds is less than 0.2%, the effect is inadequate.

Moisturizing agents used in the present invention include 1,3-butylene glycol, concentrated glycerin, propylene glycol, betaine, and can be used by selecting one or more according to the feeling and moisturizing power, the compounding amount is 1.0-15.0 based on the total weight of the composition Weight percent can be used.
