Summarize

Lipase is a stable surfactant, namely polydimethylsiloxane, which can alter the surface tension of the bubbles existing in chyme and mucus in the digestive tract, and cause them to disintegrate. The released gas can be absorbed by the intestinal wall or excreted through intestinal peristalsis.

Pharmacological action

Methyl silicone oil is a stable surfactant, namely polydimethylsiloxane, which can alter the surface tension of bubbles existing in chyme and mucus in the digestive tract and cause them to decompose. The released gas can be absorbed by the intestinal wall or excreted through intestinal peristalsis. In China, dimethyl silicone oil or silica dioxide is often used alone as an anti-foaming agent, but the effect is relatively weak; when used in combination, the anti-foaming effect is enhanced. For example, 9.4mg of dimethyl silicone oil and 0.6mg of silica dioxide can achieve the effect of 1000mg of dimethyl silicone oil. As a complex of dimethyl silicone oil and silica dioxide, the pharmacological action of Methyl silicone oil is far superior to that of dimethyl silicone oil or silica dioxide. Methyl silicone oil is an inert substance in pharmacology and physiology. The subacute toxicity test on rats shows that methyl silicone oil has no toxic effect.

Chemical

Colorless and transparent liquid, odorless and tasteless. Soluble in toluene, carbon tetrachloride, benzene, chloroform, ether and other organic solvents, insoluble in water and ethanol. Adl 0~1.5mg/kg.

Purpose

As a surfactant: Squalane oxide exhibits outstanding surface activity and can be used in the manufacture of detergents, shampoos, hair care products, etc.
