KR20070072742A - Anhydrous cosmetic composition with cooling effect - Google Patents

Abstract

An anhydrous cosmetic composition is provided to provide the cooling effect to skin when applied or massaged without skin irritation and smell by allowing a sugar alcohol to be dissolved due to moisture existing in the skin. The anhydrous cosmetic composition with cooling effect comprises a sugar-alcohol such as erythritol, xylitol, sorbitol, mannitol, paratinose, maltitol and lactitol as a refrigerant. Regarding 100 parts by weight of the cosmetic composition, 25-90 parts by weight of the sugar alcohol is contained.

Description

Non-aqueous cosmetic composition having a cooling effect {ANHYDROUS COSMETIC COMPOSITION WITH COOLING EFFECT}

The present invention relates to a non-aqueous cosmetic composition having a cold feeling effect, and more particularly, the sugar alcohol is dissolved by moisture present in the skin when applied or massaged to the skin to impart a cold feeling to the skin and at the same time the skin. It relates to a non-aqueous cosmetic composition having a cooling effect safe to the skin without irritation, odors and the like.

Sugar alcohols include erythritol, xylitol, sorbitol, mannitol, maltitol, hydrogenated starch hydrolysate, and functional saccharides having a molecular structure in which aldehyde groups of common sugars such as glucose, maltose and xylose are reduced with alcohol groups. It is currently being used as a substitute sweetener.

In general, sugar alcohols do not have free carbonyl groups and thus do not cause maillard degeneration, are more stable to heat than other monosaccharides and disaccharides, are not easily decomposed by microorganisms, and have high endothermic properties in solution. Such sugar alcohols are mainly used as an alternative sweetener of sugar in various fields such as food, medicine, cosmetics, etc. as sugars due to poor dental ability and low calorie function.

In particular, many studies have been applied to sugar alcohols in foods, and the functions of crystallization, shape retention, stability improvement, viscosity, texture, solubility, shelf life, and water retention are well known. In addition, as shown in the following table (heat of dissolution of sugar alcohol crystals), sugar alcohol has a high heat of dissolution and has an effect of imparting a cool refreshing feeling in the mouth.

Kinds Heat of fusion (Kcal / ㎏) Erythritol -42.9 Xylitol -36.6 Sorbitol -26.5 Mannitol -28.9 Paratinos -14.3 Maltitol -5.5 Lactitol -9.4

On the other hand, in the cosmetics, the sugar alcohol is mainly used for the moisturizing and solubility-promoting effect by using with polyhydric alcohols such as glycerin, butylene glycol, propylene glycol. For example, Korean Patent Application No. 195-0018428 discloses a method for enhancing the transparency of a cosmetic soap using sorbitol, and Korean Patent Application No. 1996-7003448 discloses a plastic softener.

However, when sugar alcohol is applied to cosmetics of general emulsification or solubilization type, since the sugar alcohol is dissolved in water contained in the formulation, the cooling effect due to heat of dissolution cannot be expected at all.

In recent years, as the needs of consumers are greatly changed, there is an increasing demand for a product that can be felt immediately during or after use in addition to physiological effects such as moisturizing, wrinkles, sun protection, and whitening in cosmetics.

Accordingly, a study on a product giving a refreshing feeling by applying a cold feeling material has been published, and International Patent No. 2003/074622 and Korean Patent Application No. 2002-0083610 disclose a method of using menthol and menthol derivatives as cooling agents. Doing. However, the menthol and menthol derivatives have problems such as skin irritation, odor, etc., which are not suitable for use in cosmetics where skin safety and odor are important.

In order to solve the problems of the prior art as described above, the present invention provides a non-aqueous cosmetic composition having a cooling effect that can be given a cold feeling by dissolving sugar alcohol by moisture present in the skin when applied to the skin or massage. It aims to do it.

Another object of the present invention is to provide a non-aqueous cosmetic composition having a safe cooling effect on the skin without skin irritation, odors and the like.

Another object of the present invention is to provide a non-aqueous cosmetic composition having a cooling effect that can be applied to a variety of color cosmetics, such as facial and body products, topical products, sunscreen products, packs and massage products, lipstick or foundation. .

In order to achieve the above object, the present invention provides a nonaqueous cosmetic composition having a cooling effect, comprising a sugar alcohol as a cooling agent in the nonaqueous cosmetic composition having a cooling effect.

Hereinafter, the present invention will be described in detail.

The inventors of the present invention provide a safe and cool effect on the skin as the demand for a product that gives an effect that can be felt during or immediately after use in addition to the physiological effects such as moisturizing, wrinkles, UV protection, whitening, etc. During the research, focusing on the high heat of dissolution of sugar alcohol and applying the sugar alcohol to cosmetics of various formulations that do not contain water, it can effectively give a cooling effect, and at the same time confirm that there is no problem in skin safety, smell, etc. On the basis of this, the present invention has been completed.

Non-aqueous cosmetic composition having a cooling effect of the present invention is characterized by containing a sugar alcohol as a cooling agent.

The sugar alcohols used in the present invention can be used as long as the functional saccharides having the molecular structure in which the aldehyde group of the general saccharide is reduced to the alcohol group.

Specifically, the sugar alcohol may be erythritol, xylitol, sorbitol, mannitol, paratinose, maltitol, or lactitol, and the like, and particularly, in order to give a strong cooling effect when applied to the skin, erythritol, xylitol, sorbitol, or Preference is given to applying mannitol.

The sugar alcohol is preferably included in 25 to 90 parts by weight, more preferably 35 to 70 parts by weight based on 100 parts by weight of the nonaqueous cosmetic composition. If the content is less than 25 parts by weight, there is a problem that the sRu paper has a weak cooling effect during skin application or massage, and when it exceeds 90 parts by weight, it is difficult to form and stabilize the formulation as a cosmetic composition.

The non-aqueous cosmetic composition of the present invention comprising the above-mentioned sugar alcohol as a cold sensitizer may further include an oil component, a dispersant, a fatty alcohol, a sunscreen or the like used in a conventional cosmetic composition in addition to the sugar alcohol, As a matter of course, it may further include additives such as perfumes, preservatives, surfactants, etc. that are applied to the conventional cosmetic composition.

It is preferable to manufacture the cosmetic composition of this invention which consists of such components as non-aqueous which does not contain water.

The non-aqueous cosmetic composition having a cooling effect of the present invention as described above can be applied to a variety of color cosmetics, such as facial and body products, topical products, sunscreen products, packs and massage products, lipstick or foundation.

In addition, the non-aqueous cosmetic composition of the present invention is used for the skin and may have a formulation such as powder, ointment, lotion, suspension, emulsion, cream, or spray, which is suitable for each of these formulations and is well known in the art. Conventional carriers and additives may be included.

Hereinafter, preferred examples are provided to help understanding of the present invention, but the following examples are merely to illustrate the present invention, and the scope of the present invention is not limited to the following examples.
