Recently I saw some netizens on the Internet asking whether stearyl alcohol is a hormone? The supply of stearyl alcohol means stearyl alcohol This is a shot while lying down. Stearyl alcohol is a fatty acid that has nothing to do with hormones. It is mainly used as surfactant and emulsifier in cream cosmetics. The following is a detailed introduction to hormones and stearyl alcohol.


1. Introduction to hormones:


1. Hormones are produced by certain tissues of the normal body, and then A type of chemical substance that diffuses into the blood and is transported by the blood circulation to other tissues of the body to exert special physiological effects.

Highly effective biologically active substances secreted by endocrine glands or endocrine cells, which serve as messengers in the body to transmit information and have an impact on the body. Substances that regulate physiological processes are called hormones.

Chemical substances that transmit information through blood circulation or tissue fluid are called hormones. The secretion of hormones is very small, at the level of nanograms (one billionth of a gram), but its regulatory effects are extremely obvious. Hormones have a wide range of functions, but they do not participate in specific metabolic processes. They only regulate specific metabolic and physiological processes, regulating the speed and direction of metabolic and physiological processes, thereby making the body’s activities more adaptable to changes in the internal and external environment.


2. Hormones are generally divided into four categories according to their chemical structures.

The first category is steroids, such as adrenocortical hormones (cortisol, aldosterone, etc.), sex hormones (estrogen, progesterone and androgens, etc.).

The second category is amino acid derivatives, including thyroxine, adrenomedullary hormone, pineal gland hormone, etc.

The structure of the third type of hormones is peptides and proteins, such as hypothalamic hormones, pituitary hormones, gastrointestinal hormones, insulin, and calcitonin Su et al.

The fourth category is fatty acid derivatives, such as prostaglandins.

Biostearyl alcohol introduction:


1. Stearyl alcohol is a fatty alcohol

Can be produced by hydrolysis of pilot whale oil, or by hydrogenation of stearic acid under the catalysis of copper chromate Obtained, or reduce ethyl stearate with saturated ethanol. It can also be obtained by controlling the polymerization reaction of ethylene under the action of alkyl aluminum, and then obtain the heptadecene fraction through oxo synthesis. Or the oil is then methyl esterified and then hydrogenated and fractionated.


2. Main uses of stearyl alcohol

Stearyl alcohol can Used as a dispersant in pharmaceuticals, as a base material (emulsifier) ​​for creams and emulsions in cosmetics, as a rice field heat preservation agent, water surface covering agent, defoaming agent, polishing agent, lubricant, flotation agent, softening agent Raw materials, antioxidants, stearyl tertiary amines and stearyl esters for pharmaceutical ointments (medical ointments). It can be used to produce surfactants (Pingpinga), synthetic resins and synthetic rubbers, color film couplers, etc. </span
