(3β)-Stigmast-5-en-3-ylpalmitate - Introduction
Sitosteryl palmitate(Sitosteryl palmitate) is a fatty Ester compound formed by the esterification of sitosterol and palmitic acid. It has the following properties:
1. Appearance: white to yellowish crystalline powder.
2. Solubility: Soluble in organic solvents (such as chloroform, alcohols), but almost insoluble in water.
3. Melting Point: usually between 60-70 ℃.
The main uses of Sitosteryl palmitate are as follows:
1. Food additives: as a food improver, can be used to improve food texture, increase the stability of dairy products.
2. Cosmetics: As a skin softener and emulsifier, Sitosteryl palmitate is often used in skin care products, cosmetics and pharmaceutical preparations to improve its texture and stability.
3. Pharmaceutical excipients: Sitosteryl palmitate is used as an excipient in the pharmaceutical industry, and can be used for the preparation of drug liposomes, sustained-release agents and stabilizers.
Sitosteryl palmitate is generally prepared by reacting sitosterol with palmitic acid in the presence of an esterifying agent. Specific preparation methods may include a solvent method, a transesterification method, and the like.
From a safety perspective, Sitosteryl palmitate is considered a safe food additive and cosmetic ingredient. However, it is still necessary to follow the correct operation and appropriate concentration when using it to ensure its safety and effectiveness. For pharmaceutical preparations, it also needs to be used according to the guidance of a doctor or pharmacist. In some specific situations (such as allergies, sensitive skin, etc.), it may cause discomfort to individuals, so it is recommended to perform a skin test before use, also follow the instructions and contraindications of the relevant product.
