Abstract

The invention provides a phenylethyl resorcinol lipid nanoparticle as well as a preparation method and use thereof. The phenylethyl resorcinol lipid nanoparticle is composed of an active component phenylethyl resorcinol, lipid, an emulsifier, a co-emulsifier and a stabilizer; the phenylethyl resorcinol lipid nanoparticle is faint yellow and semi-transparent and has high light stability; the phenylethyl resorcinol lipid nanoparticle is transparent and blueing after being dispersed by hot water; the colour of the phenylethyl resorcinol lipid nanoparticle still cannot be changed after being illuminated for a month; the phenylethyl resorcinol lipid nanoparticle can be freely matched with cosmetic formulae; the preparation method of the phenylethyl resorcinol lipid nanoparticle is simple, controllable and good in repeatability; and in addition, after being applied to cosmetic formulae, the phenylethyl resorcinol lipid nanoparticle has the effects of whitening skin, improving skin touch and moisturizing.

Description

technical field [0001] The invention relates to the technical field of carrier systems in cosmetic preparation technology, and more specifically relates to phenethyl resorcinol lipid nanoparticles and its preparation method and application. Background technique [0002] The full name of phenylethyl resorcinol is 4-(1-phenylethyl)-1,3-resorcinol, which is a white crystalline solid with the molecular formula C 14 h 14 o 2 , molecular weight: 214.27g / mol, melting point: 78-82°C. Phenylethyl resorcinol has an excellent skin whitening effect, and its main function is to inhibit the rate-limiting enzyme tyrosinase, which is one of the most active tyrosinase inhibitors reported. In the analysis experiment of B16V melanocytes, phenylethyl resorcinol is the most effective in inhibiting melanin synthesis among all test compounds, and its IC 50 The value (50% inhibitory concentration) was 2uM; the MTT test carried out in B16V cells confirmed that the whitening effect of phenylethyl...
