Description

A cosmetic composition containing butyl glycerin ether,

 The present invention relates to a cosmetic composition containing specific glycerin derivatives and having enhanced effects in various aspects.

The present invention also relates to various useful uses of certain glycerin derivatives as cosmetic ingredients.

Moisturizing is deeply involved in various components of various products such as cosmetics and human body goods, food, pesticide, feed, medicines and the like. Moisturizing function of these products is well known as one of important quality functions.

Polyhydric alcohols such as glycerin, 1,3-butylene glycol and sorbitol are mainly used as moisturizers used in cosmetic materials. In addition, pyrrolidone carboxylate and lactate salt, which are the main components of NMF (natural moisturizing factor), are used, and hyaluronic acid sodium produced from microorganisms is also used.

In addition, the moisturizing agent plays an important role not only in the action of the product itself as a moisture retaining agent but also in contributing to the maintenance of the stability of the system. Polyhydric alcohols such as glycerin and sorbitol have excellent moisturizing and water retention ability and are the most versatile moisturizers in terms of safety, stability, and price.

However, in the case of polyhydric alcohols such as glycerin, 1,3-butylene glycol and sorbitol, if the content of the polyhydric alcohol is increased to increase the moisturizing effect, the product quality is deteriorated due to the sticky feel, and the use amount is limited.

In addition, recently, preservatives have been exposed to human hazards, and social and legal regulations on preservatives have been intensified, and new products that do not become contaminated with microorganisms without preservatives are required.

Accordingly, a problem to be solved by the present invention is to provide a cosmetic ingredient having excellent moisturizing ability, low stickiness, various useful properties, and a cosmetic composition containing such a cosmetic ingredient.

The present invention also provides various beneficial uses of the cosmetic ingredients.

In order to solve the above problems, the present invention provides a cosmetic composition comprising butylglycerin ether of the following formula (1) as a moisturizing agent.

In order to solve the problems of the prior art, the inventors of the present invention have tested various components. When the butyl glycerin ether of the above formula (1) is used in the case of using a polyhydric alcohol such as glycerin, 1,3-butylene glycol or sorbitol The moisturizing effect can be achieved without tackiness. As a result, the use of the moisturizing agent and the deterioration of the quality can be prevented, and the butylglycerin ether has excellent solubilization ability and emulsion stabilization ability in addition to moisturizing effect and sticky feeling improving effect The present invention has been accomplished based on the discovery that butyl glycerin ether has antimicrobial effect against various microorganisms, and that the cosmetic composition is stabilized and the dispersion stability of the powder is enhanced.

When the butyl glycerin ether according to the present invention is contained as a moisturizing agent, the content thereof is preferably 1 to 10% by weight, more preferably 2 to 5% by weight, based on the total amount of the total cosmetic composition. When the content of butyl glycerin ether is less than 1% by weight, it does not greatly contribute to the moisturizing effect. If the content exceeds 10% by weight, the feeling of use may become sticky.

As noted above, the present invention is also based on several beneficial effects of the butyl glycerin ether. That is, the present invention provides various uses of the butyl glycerin ether as a cosmetic ingredient.

Specifically, the present invention provides a cosmetic composition comprising butyl glycerin ether of Formula 1, wherein the stability of the cosmetic composition is improved. Butyl glycerin ether as a cosmetic ingredient component according to the present invention is considered to be very advantageous for the stability of a cosmetic composition because of its excellent solubilization ability and emulsion stabilizing ability as compared with a conventional moisturizer. However, the effect of stabilizing the composition of butyl glycerin ether of the present invention is not limited to the above theoretical assumption. Accordingly, the butyl glycerin ether according to the present invention can be used for improving the stability of various formulations such as an underwater type or a water-in-oil type cosmetic composition, emulsion, microemulsion, skin, lotion, cream, etc. However, the present invention is not limited to this formulation . The present invention also provides a method for improving the stability of a composition characterized by adding butyl glycerin ether to a cosmetic composition.

Preferably, the present invention is characterized in that it comprises water of 1-60% by weight of the total composition by weight of the composition, 1-10% by weight of moisturizer, 1-5% by weight of surfactant, 1-30% by weight of oil, A water-in-oil type and a water-in-oil type.

In the cosmetic composition with improved stability according to the present invention, the water-soluble component may be water-soluble and may be used in cosmetics without impairing the object of the present invention. For example, it is possible to use, for example, at least one selected from the group consisting of guar gum, xanthan gum, sodium chondroitin sulfate, sodium hyaluronate, gum arabic, sodium alginate, collaginan, methylcellulose, hydroxymethylcellulose, carboxylvinyl polymer, polyvinyl alcohol, polyvinylpyrrolidone, Water-soluble polymers such as carboxyl vinyl polymer and sodium polyacrylate; Salts such as sodium chloride, magnesium chloride, sodium lactate and the like; Plant extracts such as ginger, yellow ryegrass, rhododendron, rhododendron, birch, ginseng, ginseng, iris, grapes, lilies, aloe vera, aloe vera, cucumber, lemon, lavender and rose may be used alone or in combination have.
