Cosmetic Raw Materials UV Absorber CAS 118-60-5 Ethylhexyl Salicylate/2-Ethylhexyl Salicylate

Grape seed extract contain procyanidine, is an antioxidant, anti-mutation, anti-cancer, anti-viral, anti-inflammatory, anti-ulcer, and cholesterol-lowering effects.

China H&Z® ZincG lycinate is a high-tech product with the main ingredient of zinc glycinate chelate, which can be directly absorbed and utilized by human body. Compared with the secondary generation of food enrichment, such as zinc lactate and zinc gluconate, zinc glycinate chelate overcomes the disadvantage of low bioavailability.

China H&Z® Pyrrolidine is a colorless liquid，Pyrrolidine can be used for organic synthesis. Pesticides. Fungicide. Curing agent for epoxy resins. Rubber accelerator. Inhibitors.

China H&Z® L-Pyroglutamic Acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.It is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. Pyroglutamate is found in many proteins including bacteriorhodopsin. N-terminal glutamic acid and glutamine residues can spontaneously cyclize to become pyroglutamate, or enzymatically converted by glutaminyl cyclases. This is one of several forms of blocked N-termini which present a problem for N-terminal sequencing using Edman chemistry, which requires a free primary amino group not present in pyroglutamic acid. The enzyme pyroglutamate aminopeptidase can restore a free N-terminus by cleaving off the pyroglutamate residue.
