Everything You Want Gathered Under One Roof-From Cosmetic Raw Materials To Nutritious Supplementary
Products Description
4 Butylresorcinol is the most effective spot lightening and whitening cosmetic ingredient in the global cosmetics industry. As the main R&D and production product of ZHENYIBIO., which has been focusing on the production of cosmetic raw materials for more than 12 years. 4-Butylresorcinol has excellent quality, favorable price, and stable supply. Widely used in cosmetics, rubber industry, and pharmaceutical fields.
4 Butylresorcinol is a white compound powder with a characteristic odor. Not only can it inhibit the formation of tyrosinase and reduce melanin deposition, but it can also inhibit the conversion of already deposited melanin to the stratum corneum, achieving the effect of lightening spots and whitening. In numerous experiments both domestically and internationally, it has been confirmed that the whitening effect of 4-butylresorcinol is 7 times that of phenethyl resorcinol (377), 25 times that of kojic acid, 320 times that of arbutin, and 220 times that of hydroquinone.

4 Butylresorcinol benefits
Due to its significant whitening and spot lightening effects, 4-Butylresorcinol is used as an active ingredient in cosmetics with stable effects.
4 Butylresorcinol is a small molecule compound that can penetrate below the stratum corneum:
1) Inhibit tyrosinase activity and prevent melanin deposition.
2) Resist UV induced melasma and age spots, effectively whitening.
3) Anti sugar and antioxidant properties, preventing free radicals from damaging skin DNA.
Due to its antioxidant and anti-aging properties, it can improve the durability of rubber products in the rubber industry.
In addition, it can be used as a synthetic raw material and intermediate in the pharmaceutical field.
4 Butylresorcinol soluble
Easy to dissolve in ethanol and most organic solvents, difficult to dissolve in water. When adding to cosmetics based on water, organic solvents should be added to assist in dissolution.
4 Butylresorcinol Application & Reference Dosage
Suggest adding 0.3% -0.5% for the best whitening effect.
Experimental results have shown that 0.3% 4-butylresorcinol is much more effective than 0.5% phenethyl resorcinol.
