Abstract

The invention discloses a kind of whitening cosmetic compound, the cosmetic composition contains licorice 0.2 10 parts (parts by weight), plays a part of suppressing melanin generation so as to skin whitening.The licorice that the present invention contains, which has, to be suppressed the activity of tyrosinase and dopachrome interconvertible enzyme (TRP 2), hinders 5, and the polymerization of 6-dihydroxy indole (DHl) reaches the effect of skin whitening to prevent the generation of melanocyte;Moreover, the active skull cap components that licorice contains, will not stimulate skin, stable absorption ability is strong, and it is good to the security of skin in cosmetics to add.

Description

A kind of whitening cosmetic compound
Technical field
The invention belongs to cosmetic field, more particularly to a kind of whitening cosmetic compound.
Background technology
In recent years because environmental pollution aggravates, more and more easily there is color in reason, the skin of people such as operating pressure increase Element imbalance, forms permanent foxiness, freckle.Daily illumination can also cause dermal melanin calm, and accumulating over a long period causes skin face Discoloration blacking is dark, accelerates aging.
Skin color is mainly determined by the content of melanin in skin.When sunray irradiates skin, skin is in order to certainly I protects, and melanocyte can produce substantial amounts of melanin to absorb illumination middle-ultraviolet lamp.Melanin primarily forms process such as Under:The activity of tyrosinase is become strong by ambient light photograph or body hormonal stimulation in cell, with internal aliphatic acid or tyrosine Reaction, DOPA quinone is generated, the oxidation through enzyme or non-enzymatic, haematochrome or colourless pigment are changed into melanin.Melanin passes through The osmosis of cell reaches superficial skin, causes colour of skin blackening, produces foxiness, freckle.Therefore, hinder or suppress melanin life Into first stage in tyrosinase effect, you can suppress melanin generation, and tyrosinase can be hindered or suppress by seeking The medicine of effect, it is particularly important for thirsting for the people seeking beauty of skin brilliant white to prevent or suppress the generation of melanin.Expect There is a kind of skin-lightening cosmetic, tyrosinase activity can be hindered, or act on each stage of melanin metabolic pathway, press down The generation of melanin processed, makes skin shine whitening.
In order to seek to hinder or suppress the medicine of tyrosinase effect, to prevent or suppress the generation of melanin, this Development project develops a kind of cosmetic composition containing natural materials active component, acts on the first rank of melanin generation Section suppresses the activity of tyrosinase, reaches the effect of skin whitening.
Licorice, it is that to be extracted from radix glycyrrhizae have the composition of medical value, generally comprises:Glycyrrhizin, glycyrrhizic acid, Liquiritin, licoflavone, rear curtain are than wingceltis element, formoononetin, Quercetin etc..Largely research shows, glycyrrhizin and flavones Class material is most important physiological activator in radix glycyrrhizae, the part being primarily present within licorice, stem epidermis.Radix glycyrrhizae is extracted Active material in thing, which has, to be suppressed the activity of tyrosinase and dopachrome interconvertible enzyme (TRP-2) in Skin Cell, absorbs purple The effect of outside line.
The content of the invention
The purpose of the present invention is added using natural active material in cosmetic composition to suppress melanin generation in fact The effect of existing skin whitening.In order to solve the above problems, the present invention provides a kind of skin-lightening cosmetic group containing licorice Compound, concrete scheme are as follows:

Whitening is tested
The method of UV white whitening toner is prepared to be verified to the effect of the present invention according to embodiment 2 according to table 1 below.
Table 1
In order to determine above-mentioned Production Example 1, Production Example 2, Production Example 3, the change effect of 1 pair of skin surface of Production Example 4 and contrast Fruit, confirm the improvement of skin complexion, tested using 20-40 year healthy women 20 as object, these people are divided into 5 Group, every group of 4 people, sample is used to each group, observed data and result take every group of average value.In room conditions, Yu Zao Sample application coating 2 times, each 3ml daily, is applied 4 weeks altogether in whole face after late face cleaning.Using using colorimeter The change (Δ L*) of same look-out station skin color, records and unites before and after (Minolta CM-3500d) measure subject smears The average value of colourity before and after meter measurement.
L* values (brightness) are primarily used to index in the present invention.L* values are corrected by standard edition, and in a portion Point upper duplicate measurements 5 times or more, to eliminate measurement error.Represent that pigmentation is relieved when Δ L* values are about 2, if More than 1.5, can be judged as with whitening effect.
According to the front and rear result of measure, skin color degree of improvement is calculated with following equatioies (1).
Equation (1):Δ L*=L* (after using 4 weeks)-L* (before use)
The average value of each test group see the table below 2
Table 2:
Sample sets L* (before use) L* (after using 4 weeks) ΔL*
Production Example 1 37.25 43.87 6.62
Production Example 2 36.96 43.88 6.92
Production Example 3 37.61 41.19 3.58
Production Example 4 38.13 42.68 4.55
Comparative example 1 38.78 38.93 0.15
To be found out by the result of table 2, toner of the comparative example 1 without licorice is faint to the whitening effect of skin, Production Example 1, Production Example 2, Production Example 3, Production Example 4 have whitening effect, wherein Production Example 1, the whitening effect of Production Example 2 to skin It is the most notable.
It is described above, it is the embodiment of the present invention, but protection scope of the present invention is not limited thereto, and it is any ripe Know those skilled in the art the invention discloses technical scope in, various equivalent modifications can be readily occurred in or replaced Change, these modifications or substitutions should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be with right It is required that protection domain be defined.
