Isosorbitol dimethyl ether is used as an excipient in the field of medicine for topical applications such as ointments and tinctures. It can also be used in cosmetics to significantly enhance the effect of sunscreen, wrinkle resistance, spot removal, acne elimination, skin care and moisturizing, weight loss, breast cream, hair growth agent, hair dye and other products. It is an ideal solvent, penetrant and carrier in the cosmetics industry. It can also be used for pesticides, which can enhance the penetration of pesticides inside and outside pests, enhance efficacy, reduce pest resistance, reduce environmental pollution, and especially reduce the direct harm of pesticides to humans.

Polyammonium chloride is a cationic eye preservative that can inhibit the growth of microbial contaminants in multi dose bottle topical medications.

Exchange resin has been used as a drug stabilizer to mask or improve the taste of drugs, or as a sustained-release formulation, or as a drug carrier. Some Polaklin resins can also be used in the analysis and production of drugs and food.

SNAC is an oral absorption enhancer with the potential to serve as a delivery agent for heparin and insulin in oral form. SNAC can increase the lipophilicity caused by non covalent macromolecular complexation, thereby enhancing the passive transcellular permeability of small intestinal epithelial cells.

Lun Huan Teng Ning Tetraacetic Acid (DOTA) is a contrast agent.

Caterpillar calcium is a medicinal excipient.

Sodium thiophosphate can be used in pharmaceutical manufacturing processes for drug formulation, protection, and other purposes, playing an important role.

Petrolatum (white) is widely used as the base material of hair wax, hair cream, cold cream, skin moisturizer, anti crack cream, lotion, lipstick and other cosmetics, as well as the base material of various ointment products in pharmaceutical cosmetics.

Paraffin is a mixture of solid saturated hydrocarbons obtained from petroleum through modern refining processes such as deoiling, distillation, crystallization, and hydrogenation. The main component is straight chain alkanes, with a large crystal structure and low molecular weight, thus presenting a semi transparent solid state. Paraffin dissolves in chloroform or ether and is almost insoluble in water or ethanol. Paraffin is suitable for ointments, suppositories, patches, etc., and plays a role in thickening, adjusting hardness, and shaping.

Brazilian palm wax is a natural plant wax extracted from the leaves and buds of Brazilian wax palm.

Chitosan is a polysaccharide composed of glucosamine and acetylated glucosamine polymers, which can be obtained by partial deacetylation of chitin in the shell. It also naturally exists in certain microorganisms and yeast. The term chitosan refers to a series of chitosan polymers with different molecular weights (50 kDa to 2000 kDa), viscosities, and degrees of deacetylation (40% to 98%). Chitosan is insoluble in neutral and alkaline solutions, but can form salts with inorganic and organic acids such as glutamic acid, hydrochloric acid, lactic acid, and acetic acid. The amino groups of polymers are protonated, resulting in soluble polysaccharides with positive charges. The most commonly used chitosan salts are glutamate and hydrochloride.
