Abstract

PURPOSE:To obtain a cosmetic having low stickiness, by compounding liquid polyhydric alcohol fatty acid ester and a crude extract derived from peel of Lansium domesticum Jack var. Duke, etc., and lansic acid, lansioside, etc., which are components of the extract. CONSTITUTION:The objective cosmetic is produced by compounding (A) 0.05-1wt.% (in terms of lansic acid) one or more substances selected from crude extract obtained from peel of Lansium domesticum Jack var. Duke or Lansium domesticum Jack var. Lancer, lansic acid and lansioside which are components of the extract and their derivatives and (B) 0.1-5% liquid polyhydric alcohol fatty acid ester (e.g. neopentyl glycol di-n-decanoate). The cosmetic activates the function of dermatic cell and exhibits remarkable effect to protect and beautiful the skin. It promotes the permeation of the active component into the skin and has little stickiness.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cosmetic with low stickiness, which activates skin cell functions, exhibits remarkable effects on skin protection and beautification, and has excellent skin permeability of active ingredients.

BACKGROUND OF THE INVENTION 1. Extract obtained from the pericarp of Duke or Randium domesticum jack balansa and its specific components inhibit the activity of 5α-reductase, thereby treating androgenic alopecia associated with male hormones, locus vulgaris. It is known to be effective in preventing and treating diseases such as healing, seborrhea, and dandruff (see JP-A-60-243020).

Such effects are caused by the inhibition of 5α-reductase activity, which increases the energy production of skin cells and activates the cells.

Therefore, by blending the extract etc. as a base, it is possible to obtain cosmetics that are effective in preventing and treating various skin diseases related to male hormones, thereby regenerating and maintaining vibrant skin. be expected.

However, when cosmetics containing such extracts as a base are applied to the skin, they tend to become very sticky, making them unsuitable for use in cosmetics that require a light feel.
The skin permeability of the extract and the like has not been obtained. Therefore, it alleviates the sticky feeling when applied to the skin, and
There is a demand for a formulation that enhances the skin permeability of the extract and the like.

The inventors of the present invention have worked hard to improve the above-mentioned drawbacks and to obtain a cosmetic that does not have a sticky feeling when applied, has enhanced skin permeability of active ingredients, and has excellent skin protection and beautification effects. As a result of their studies, they discovered that a cosmetic with good properties could be obtained by using a crude extract of Menji and/or its specific ingredients in combination with certain compounds, and completed the present invention. I ended up doing it.

DISCLOSURE OF THE INVENTION The present invention relates to a crude extract obtained from the pericarp of Randium domesticum jack barduke (hereinafter referred to as Deuda) or Randium domesticum jack barlantha (hereinafter referred to as Lanza); A cosmetic comprising one or more selected from landic acid, landioside, and derivatives thereof, and one or more selected from liquid polyhydric alcohol fatty acid esters. This is what we provide.

The extraction, separation and purification methods and structures of the crude extract, randic acid and landiside obtained from the pericarp of Deuda or Langsa to be incorporated into the cosmetics of the present invention are known (for example, JP-A No. 60-243020). reference),
Commercially available. Derivatives include rannoic acid salts (e.g., sodium salt, disodium salt, etc.), esters (e.g., monoalkyl esters having 2 to 12 carbon atoms, dialkyl esters having 2 to !2 carbon atoms, etc.), and randiosides. Examples include salts (eg, sodium salts, potassium salts, etc.), esters (eg, monoalkyl esters having 2 to 12 carbon atoms, etc.), and they can be produced by conventional methods. The crude extract, landic acid, landioside and their derivatives listed in ljq are 0.01 to 3% by weight of the total amount of the cosmetic as randic acid.
, preferably in an amount of 0.05 to I% by weight. If the blending amount is less than 0.01% by weight, sufficient medicinal efficacy will not be obtained,
Moreover, if it exceeds 3% by weight, it may become difficult to dissolve in the base.

Examples of the polyhydric alcohol of the liquid polyhydric alcohol fatty acid ester to be incorporated into the cosmetic of the present invention include ethylene glycol, propylene glycol, neopendel glycol, glycerin, diglycerin, sorbitan, etc.
The fatty acids include linear and branched saturated and unsaturated fatty acids having 8 to 22 carbon atoms, such as n-decanoic acid, 2-decanoic acid,
Examples include ethylhexanoic acid, oleic acid, and isostearic acid. The preferred blending amount of the ester is 0.01-10% by weight, preferably 0.01-10% by weight, based on the total amount of the cosmetic.
It is 1 to 5% by weight. If the amount is less than 0.01% by weight, sufficient effects cannot be obtained, and if it is more than 10% by weight, the sticky feeling will be increased, which is not preferable.

Furthermore, the cosmetics of the present invention may contain appropriate surfactants, thickeners, preservatives, bactericidal agents, antioxidants, polyhydric alcohols, fragrances, pigments, etc., as necessary, within a range that does not impair its properties. May be added.
