Abstract
本发明涉及一种含氢醌单丙酸酯和α－羟基酸的祛斑增白化妆品,主要是在含有祛斑活性组份氢醌单丙酸酯中加入具有抗皱、促进皮肤修复、增白的α－羟基酸,及抗氧剂维生素C和维生素E及皮肤营养剂氨基酸,再配以其它辅剂(如基质、乳化剂、渗透剂、防腐剂、香料、水等),采用常规乳化方法制得性质稳定的膏体。该化妆品具有性能稳定,长期存放不易氧化变色,祛斑增白效果显著,抗皱等功能。The invention relates to a speckle-removing and whitening cosmetic containing hydroquinone monopropionate and α-hydroxy acid, which mainly includes adding anti-wrinkle, promoting skin repair and whitening α- -Hydroxy acid, antioxidant vitamin C and vitamin E and amino acid skin nutrition agent, and other auxiliary agents (such as matrix, emulsifier, penetrant, preservative, spice, water, etc.), prepared by conventional emulsification method Stable paste. The cosmetic has stable performance, is not easy to be oxidized and discolored after long-term storage, has remarkable freckle-removing and whitening effects, and has anti-wrinkle and other functions.
Description
The present invention relates to the dispelling speckles and whitening face cosmetics, especially a kind of dispelling speckles and whitening face cosmetics that contain hydroquinone mono-propionate and 'alpha '-hydroxy acids
The various types of pigment obstacles of skin mainly are the effects owing to tryrosinase, tyrosine metabolism disorder in the body, and the pigment anomaly deposition causes senile plaque, brown patch, freckle etc.Will stop the formation of these brown patch artificially, mainly be the activity of restraint of tyrosinase.Known synthetic hydroquinone derivatives---hydroquinone mono-propionate has this kind function, has that zest is little, safety good, is easy to be widely used gradually by characteristics such as skin absorbs.But after making cosmetics paste, hydroquinone mono-propionate character instability, easily oxidation and variable color, thus directly influenced the exterior quality and the speckle dispelling curative effect of cosmetics.Traditional in the past solution is to add relatively large low price sulfate (as sodium sulfite, sodium pyrosulfite) as oxidation retarder, but this type of material has zest to skin, and life-time service can produce infringement to skin.
One of known melanic excretion pathway is to discharge through skin, and promptly melanin is transferred in the keratin, with the epidermal growth horny layer of dividing a word with a hyphen at the end of a line, comes off with the horny layer metabolism at last.'alpha '-hydroxy acids has comes off dead Skin Cell, thereby promotes skin repair, and delay skin aging reduces characteristics such as mottle.
The object of the invention is, a kind of dispelling speckles and whitening face cosmetics that contain hydroquinone mono-propionate and 'alpha '-hydroxy acids are provided, mainly be in containing speckle dispelling active constituent hydroquinone mono-propionate, add have crease-resistant, promote skin repair, the 'alpha '-hydroxy acids that brightens, and antioxidant vitamin C and vitamin E and skin-nourishing agent aminoacid, be equipped with other adjuvant (as substrate, emulsifying agent, penetrating agent, antiseptic, spice, water etc.) again, adopt conventional emulsification method to make the mastic of stable in properties.
Principle of the present invention is the adding of 'alpha '-hydroxy acids in the cosmetics, and may command mastic pH value is in the 4-6.5 scope, and with this understanding, the chemical property of hydroquinone mono-propionate is stable, is difficult for oxidized.And 'alpha '-hydroxy acids have the activation Skin Cell, crease-resistant, brighten isoreactivity, with the composite synergism of hydroquinone mono-propionate with dispelling speckles and whitening face.Vitamin C and vitamin E promptly can be used as antioxidant in this cosmetic formulations, suppress the oxidation of hydroquinone mono-propionate, again with prescription in the same effect of aminoacid that adds with nutrition skin, vitamin C is the effect of Pear Power skin also.
A kind of dispelling speckles and whitening face cosmetics that contain hydroquinone mono-propionate and 'alpha '-hydroxy acids of the present invention, the consumption of hydroquinone mono-propionate is 0.5-20 part in cosmetics, 'alpha '-hydroxy acids is lactic acid or hydroxyacetic acid or malic acid or citric acid or tartaric acid or its mixture, its consumption is 1-20 part, vitamin is a vitamin C, vitamin E, its consumption is 0-2 part, aminoacid is cystine or glycine, its consumption is 0-1 part, be equipped with other cosmetics adjuvant again (as substrate, emulsifying agent, penetrating agent, antiseptic, spice, water etc.), adopt conventional emulsification method preparation, pH value is that 4-6.5 gets final product.
The present invention has carried out embrocating test to the patient who suffers from brown patch, freckle: wipe examination with the mastic that contains 3.6% (weight ratio) hydroquinone mono-propionate and 8.7% (weight ratio) 'alpha '-hydroxy acids, use its result of person such as following table more than two months continuously:
