Paraformaldehyde (PFA) is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde commonly has a slight odor of formaldehyde due to decomposition. Paraformaldehyde is a poly-acetal.

It usually appears as white to grayish white. However, in some industrial-grade products, due to factors such as production processes and impurities, the appearance may have a slightly yellowish-brown tint. The product appears in powder form, with a fine and uniform texture, good fluidity, and is convenient for storage, transportation, and use and operation in various production processes.

Activated Carbon, with the CAS number 64365-11-3, is a specially treated carbon material. It has a rich pore structure inside, which endows it with an extremely large specific surface area, thus having an extremely strong adsorption performance and playing a key role in many fields.

Benzothiazole and its derivative are recognized as the most important heterocyclic compounds. This series of compounds is of particular interests. It has various kinds of pharmacological properties and has been included in many kinds of natural products and pharmaceutical agents.

Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate or Di(2-ethylhexyl) terephthalate), commonly abbreviated DOTP or DEHT, is an organic compound with the formula C6H4(CO2 C8H17)2.

Phthalate ester used as plasticizers and additives. Used in toxicology studies as well as risk assessment studies of food contamination that occurs via migration of phthalates into foodstuffs from food-contact materials (FCM).

Olivetol, also known as 5-pentylresorcinol or 5-pentyl-1,3-benzenediol, is an organic compound found in certain species of lichen; it is also a precursor in various syntheses of tetrahydrocannabinol.

Guanidine carbonate is a chemical substance with the chemical formula C2H10N6H2CO3 and its appearance is a white crystalline powder.

Cyclopentanone is the organic compound with the formula (CH2)4CO. This cyclic ketone is a colorless volatile liquid.

Acetyltributylcitrate is an organic compound that is used as a plasticizer. As such, it is a potential replacement of DEHP and DINP. It is a colorless liquid that is soluble in organic solvents. It is found in nail polish and other cosmetics. It is prepared by acetylation of tributylcitrate.

Oleoyl ethanolamide is an N-(long-chain-acyl)ethanolamine that is the ethanolamide of oleic acid. The monounsaturated analogue of the endocannabinoid anandamide. It has a role as a PPARalpha agonist, an EC 3.5.1.23 (ceramidase) inhibitor and a geroprotector.
