Application
4-(1-Phenylethyl)-1,3-benzenediol is an novel active ingredient of highly efficient skin lightening agents.
Extremely effective tyrosinase inhibitor with excellent antioxidant function. It is widely used in various whitening, freckle and anti-aging products. It can reduce skin coloration caused by ultraviolet radiation and can improve uneven skin tone.
Phenethyl resorcinol (377) is a high-efficiency new skin whitening agent derived from silver pine, with a superb potential whitening effect: in vitro experiments have also proven to be dozens or even hundreds of times stronger than VC. And clinically confirmed that its whitening ability is equivalent to that of hydroquinone.
The most important thing is that the whitening speed is fast and it is flattering to consumers. After more than ten years of continuous understanding of the nature and safety of these raw materials, it is gradually getting permission from various countries. It is gradually used in cosmetics. It is a kind of Emerging efficient natural actives.
Phenyl resorcinol is difficult to dissolve in water, and is easily oxidized and discolored, which limits its application in cosmetics. The use of nano-active substances with a particle size of less than 30 nm developed by the nano-transmission system (NDS) will convert Ethyl resorcinol is stably wrapped in a nano-carrier, which can greatly increase absorption efficiency and bioavailability, overcome the original defects well and maintain advantages, and it is more convenient and widely used.
Phenethyl resorcinol can effectively inhibit melanin synthesis by acting on multiple targets of the melanin synthesis pathway, thereby achieving whitening and brightening effects. Super strong antioxidant, effectively remove harmful free radicals from the skin, fight aging and wrinkles caused by free radicals.
 
Skin care effect
1. Inhibit melanin synthesis, reduce pigmentation, whiten skin
2. Eliminate free radicals, anti-oxidation, and fight against skin aging
3. Reduce acne marks

Original research drugs: industry entry barriers are high, performance stability and certainty are high.(R)-4-Benzyl-2-oxazolidinone CAS:102029-44-7 Process: The importance of safety is obvious. The research and development of specialty drug substances (especially high-barrier generic drug substance drugs) usually need to avoid the original process patents, and some chemicals are developed because of the complex structure or the harsh synthetic conditions The synthetic route is more difficult, so the importance of process design capabilities of API companies is becoming more important.1-bencil-4- (fenilamino) piperidina-4-carbonitrilo CAS:968-86-5 An effective treatment for Alzheimer’s, which is estimated in 60%-70% of around 50 million dementia cases worldwide, could become one of the best-selling drugs globally.It does not require a production license for the drug substance, and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for the synthesis of the drug substance.
