Whitening composition and application thereof

Abstract

The invention discloses a whitening composition and application thereof. The invention further discloses a whitening cosmetic prepared from the whitening composition, and the whitening cosmetic is prepared from the following components in percentage by mass: 0 to 2% of glutathione, 0 to 5% of hydroxyapatite, 0 to 2% of an amino acid stabilizer, 0 to 1% of proteoglycan, 0 to 2% of 4-butylresorcinol, 0 to 5% of glycerol, 0 to 4% of methylpropanediol, 0 to 2% of butanediol, 0 to 2% of 1, 2-pentanediol, 0 to 0.1% of sodium polyglutamate, 0 to 0.2% of carbomer, 0 to 0.2% of sphingosine gum, 0 to 2% of glyceryl polyether-26, 0 to 2% of PEG / PPG-17 / 6 copolymer, 0 to 0.5% of p-hydroxyacetophenone and the balance of water. By regulating and controlling the proportion of hydroxyapatite / cysteine / proteoglycan in the whitening composition and synergistic compatibility of the components, the odor of glutathione can be eliminated, meanwhile, 4-butylresorcinol is stabilized, the stability of 4-butylresorcinol is improved, and the irritation of 4-butylresorcinol is reduced; the obtained whitening product is ensured to have the minimum smell, the minimum color change, the minimum irritation and the best whitening effect, and the performance in all aspects is optimal.

Description

Technical field [0001] The present invention relates to the field of skin care technology, and more particularly to a whitening composition and its application thereof. Background technique [0002] As the whitening freckle market is getting hot, due to the current market, the white freckle products are inefficient, the side effects are large, the product stability is difficult, so it is generally necessary to carry out whitening freckles through medical means, such as laser, water jet, bristles Skin, etc. [0003] Disadvantages of various common white agents in the prior art: glutathione is binding from glutamic acid, cysteine, and glycine, and has a thiol group having antioxidant and integrated throison effect. Can eliminate human free radicals and improve human immunity. Glutathione released by Merle Norman in the United States, using the latest science and technology in skin pigment research, developing exclusive "BAIDI Peptide and high concentrations" and other unique ingred...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of various commonly used whitening agents in the prior art: 1. Glutathione is a tripeptide combined with glutamic acid, cysteine ​​and glycine and contains a sulfhydryl group, which has antioxidant and integrated detoxification effects. Can eliminate free radicals in the human body and improve human immunity

However, the stability of glutathione is not good when it is used in cosmetics, and it will produce an unpleasant smell and affect the sense of use; Strong inhibitor of tyrosine and peroxidase

However, this ingredient is too irritating to the skin and can easily cause skin allergies

Moreover, this type of ingredient is sensitive to factors such as light and heat, and products containing this ingredient are prone to discoloration, which affects the stability of the product; 3. The irritation and instability of phenylethyl resorcinol / arbutin / nicotinamide, etc. Sex, instability and irritation of vitamin C and its derivatives
