Abstract

PURPOSE:To obtain a cosmetic having excellent moisture-retaining effect, giving non-sticky feeling to the skin and having suppressed slipperiness on the skin, by compounding a soluble collagen in combination with powder to a cosmetic base. CONSTITUTION:The objective cosmetic contains 0.01-2wt% soluble collagen and/or its derivative and 1-20wt% inorganic powder such as talc, mica, calcium carbonate, etc., or organic powder such as crystalline cellulose, nylon powder, etc. The soluble collagen is preferably the one solubilized by protease treatment because the telopeptides are removed from the collagen by the treatment to eliminate the allergic property and the obtained cosmetic has high safety to the skin. A derivative produced by treating the soluble collagen with a polybasic acid may be used in place of the soluble collagen.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a novel cosmetic that has an excellent moisturizing effect, has a non-sticky feel, and suppresses slippage when applied. be.

[Conventional technology]

Maintaining skin moisture within an appropriate range is extremely important from the perspective of skin health, and many cosmetics are available for the purpose of moisturizing.

Research into substances involved in skin moisturization is progressing, and many moisturizers are now in use, including polyhydric alcohols such as propylene glycol and sorbitol.

Under these circumstances, collagen has been attracting particular attention recently. Collagen is a hard protein that is present in large amounts in the dermis of the skin, connective tissues, bones, and the like. Skin aging progresses due to tissue aggregation in the dermis. That is, collagen, which initially existed in the intercellular interstitium of tissues in the form of fibers, increases the degree of intramolecular or intermolecular bonding and becomes reticulated as we age. As reticulation occurs, the water binding ability of collagen fibers decreases, resulting in loss of swelling and elasticity. During this process, the skin hardens, wrinkles increase, and at the same time it loses its ability to retain water, leading to aging.

In view of the above-mentioned circumstances, attempts have been made to incorporate collagen, particularly soluble collagen, into skin cosmetics for the purpose of restoring the elasticity of the skin and making it moist.

However, despite its excellent moisturizing effect, soluble collagen has a strong sticky feel, and furthermore, when applied to the skin, it tends to slip on the skin and is difficult to absorb.

[Problem that the invention seeks to solve]

In view of these circumstances, the inventors of the present invention have conducted intensive studies aimed at suppressing the stickiness of collagen and improving its adhesion to the skin when applied. Alternatively, the present inventors have discovered that this object can be achieved by combining two or more types, and have completed the present invention.

[Means for Solving the Problems] That is, the present invention comprises 0.01 to 2% by weight of one or more types of soluble collagen and its derivatives, and 1 to 20% by weight of one or more types of powder. A cosmetic characterized by containing:

Any soluble collagen may be used as the soluble collagen used in the present invention, but for example, soluble collagen solubilized by protease treatment (Japanese Unexamined Patent Publication No. 1983-1979)
No. 110336) is preferable in terms of skin safety because it is non-allergenic since telopeptide is removed.

The product is atelocollagen (molecular weight 300,000), which is purified by treating insoluble collagen obtained from calf dermis with protease at room temperature for 1 to 2 days, sold by Kouken ■.
etc. Furthermore, a soluble collagen derivative obtained by treating soluble collagen with a polybasic acid may also be used.

Examples of products include Atelocollagen SS, which is treated with succinic acid and manufactured by Koken ■. The blending amount of soluble collagen is 0.01 to 2% by weight based on the total amount of the cosmetic of the present invention. If it is less than 0.01%, the moisturizing effect will be poor and the stickiness will be low.

If it exceeds 2% by weight, the solubility will deteriorate.

The powder used in the present invention may be either inorganic or organic, and conventionally known powders can be used.

For example, inorganic powders such as talc, mica, kaolin,
Calcium carbonate, zinc white, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine, navy blue, chromium hydroxide, bismuth oxychloride, titanium-mica pearl pigments, etc.
Examples of the organic powder include crystalline cellulose, nylon powder, and polyethylene powder.

The blending amount is 1 to 20% by weight. If it is less than 1% by weight, there is no effect, and if it is more than 20% by weight, it will not feel rich and powdery, which is not preferable.

In addition to the above-mentioned essential ingredients, the cosmetics of the present invention include polyhydric alcohols, oily ingredients, ultraviolet absorbers, lower alcohols, surfactants, preservatives, pigments, fragrances, and drugs that are commonly used in cosmetics. Other components may be added as appropriate within a range that does not impair the effects of the present invention.

Further, the dosage form of the cosmetic of the present invention is arbitrary, and may include solubilized type,
It can be an emulsion system, a powder dispersion system, etc. It can be used in a wide range of applications, including basic cosmetics such as lotions, emulsions, and creams, as well as makeup cosmetics such as foundation, and hair cosmetics.

[Effects of the Invention] The cosmetic of the present invention contains soluble collagen and has an excellent moisturizing effect, and has no stickiness characteristic of soluble collagen, does not cause slippage when applied, and has a high adhesion feeling. Moreover, the stability is also good.
