Replacement of Antimony Oxide, Antimony-free Synergistic Flame Retardant for Polyester

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.

Isopropyl Myristate from H&Z® suppliers is an oily humectant with low viscosity and great spreadability. It can be dissolved with organic solvents, insoluble in water. It is one of the important additives for high-grade cosmetics, which can moisten the skin and bring the active ingredients of the cosmetics to the deep of the skin.

China H&Z® Ethyl paraben is white crystalline substance with a slightly bitter taste and burning numbness.As an antibacterial preservative, ethylparaben is widely used in cosmetics, food and pharmaceutical preparations.It can be used alone or in combination with other parabens or antibacterial agents.It is one of the most frequently used antibacterial preservatives in cosmetics.These parabens can play a role in a wide pH range, and have spectral antibacterial activity, of which the most effective for yeast and mold.Because the solubility of paraben is poor, its salts are often used.
