Carbazole is used for dyes and pigment.

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® Cinnamyl alcohol CAS:104-54-1 or styron is an organic compound that is found in esterified form in storax, Balsam of Peru, and cinnamon leaves. It forms a white crystalline solid when pure, or a yellow oil when even slightly impure. It can be produced by the hydrolysis of storax.

D-Glucurone of H&Z® factory is a naturally occurring substance that is an important structural component of nearly all connective tissues.Glucuronolactone is also found in many plant gums.
Glucuronolactone is hydrolyzed in the body to glucuronic acid, which may be oxidized to glucaric acid, or isomerized to another hexuronic acid, so there is no reasonable toxicity mechanism.

China H&Z® Saw palmetto extract is an extract of the fruit of Saw palmetto. It is rich in fatty acids and phytosterols. It has been used in traditional and alternative medicine for a variety of indications, most notably benign prostatic hyperplasia (BPH).

China H&Z® Potassium thiocyanate is colorless crystal, it is soluble in water and cools due to a large amount of heat absorption.It also dissolves in alcohol and acetone.
