Nonenyl Succinic Anhydride Manufacturers

H&Z® EDTA-2NA is White Crystalline Powder,EDTA-2NA is used as water purifier, pH regulator, chelator, polyvalent chelator and coagulant inhibitor. It is also used in textile printing and dyeing, detergent, metal coating and metallurgical industry.

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.

China H&Z® Sodium Erythorbate is White crystalline powder,Slightly salty. It is quite stable in the air in a dry state. But in solution, it will deteriorate in the presence of air, trace metals, heat and light. Melting point above 200 ℃ (decomposition). Easily soluble in water (17g / 100m1). Almost insoluble in ethanol. The pH value of the 2% aqueous solution is 5.5 to 8.0.Used as food antioxidants, anti-corrosion color additives, Cosmetic antioxidants. Sodium Erythorbate can consume oxygen in cosmetics, reduce high-valent metal ions, transfer the redox potential to the reduction range, and reduce the generation of undesirable oxidation products. Sodium Erythorbate can also be used as anticorrosive color additive.

​Vanadium pentoxide CAS NO:1314-62-1 V2O5

China H&Z® Niacinamide is a water soluble vitamin that is part of the vitamin B group. Niacin converts to niacinamide in the body. Though the two seem identical, niacinamide has it's own health benefits.

China H&Z® Gelatin is pale yellow, unscented, flavorless, hydrolyzed and granular. Gelatin is extracted from fresh, unprocessed bovine hides/bones, and it is a high molecular weight protein (without fat and cholesterol) composed of 18 amino acids. Gelatin is widely used in food, pharmaceuticals manufacturing.
