INCI Name: UNDECYLENOYL PHENYLALANINE Molecular Formula: C20H29NO3 Molecular Weight: 331.45 Appearance: White crystalline powder Purity: 98% CAS NO.: 175357-18-3 EINECS No.: 200-568-1 Application: cosmetics and skin care products Supplier: ZHENYIBIO Undecylenoyl phenylalanine is a white powder. It is a structural analogue of I±-MSH. By competitively binding the melanin stimulating hormone receptor MC1-R on melanocytes, the melanocytes cannot produce tyrosinase, thereby inhibiting the activity of melanocytes and reducing the production of melanin. According to some clinical trials, undecylenoyl phenylalanine can indeed reduce spots caused by pigmentation. According to research, this ingredient can block �±-MSH at a concentration of 0.001%, if the concentration is 1%. Then, the melanin production can be fully suppressed from multiple links, and the effect is more obvious and lasting. Undecylenoyl phenylalanine has the following characteristics: 1. Significant skin biocompatibility (lipid amino acid structure) 2. Innovative mode of action �±-MSH antagonist 3. Compared with whitening agents such as arbutin, kojic acid, and vitamin C phosphate magnesium, the effect is more significant. 4. Human experiments have proved that its whitening and lightening effect is remarkable. 5. Highly safe within the recommended dosage (2%). 6. Easy to formulate (very easy to use). 7. Has good compatibility and excellent stability
Cas 108-95-2 Factory supply liquid phenol / para amino phenol / phenol price it can also be used to disinfect surgical instruments and excreta, skin sterilization, itching and otitis media. The melting point of 43 �° C, slightly soluble in water at room temperature, soluble in organic solvents; when the temperature is higher than 65 �° C, it can be miscible with water in any ratio. P henol is corrosive and denatures local proteins after contact. Purity 99.90% Appearance White crystal solid, White Crystal Application Used in the manufacture of resins, synthetic fibers, plastics, pesticides, etc Phenol Usage 1. Phenol is an important organic chemical raw material, widely used in the production of phenolic resin and bisphenol A, in which bisphenol A is important raw material for polycarbonate, epoxy resin, polysulfone resin and other plastics. In some cases the phenol is used to produce iso-octylphenol, isononylphenol, or isododecylphenol through addition reaction with long-chain olefins such as diisobutylene, tripropylene, tetra-polypropylene and the like, which are used in production of nonionic surfactants. In addition, it can also be used as an important raw material for caprolactam, adipic acid, dyes, medicines, pesticides and plastic additives and rubber auxiliaries. 2.Purified for molecular genetics applications 3. Phenol is frequently used for medical chemical face peels. It may trap free radicals and can act as a preservative. Phenol, however, is an extremely caustic chemical with a toxicity potential. It is considered undesirable for use in cosmetics. even at low concentrations, it frequently causes skin irritation, swelling, and rashes.
