[dimethyl(trimethylsilyloxy)silyl]oxy-dodecyl-dimethylsilane - Introduction
Lauryl methicone is an organosilicon compound with the formula (C11H23)(CH3)3SiO[(CH3)2SiO]nSi(CH3)3, where n is the number of polymethylsiloxane units. It is a colorless to pale yellow liquid with low viscosity and good stability.
Lauryl methicone is widely used in cosmetics and personal care products. It has good lubricity and permeability, and can be used as an emulsifier, foaming agent, anti-foaming agent, lubricant, antistatic agent and anti-viscosity agent for cosmetics. It can also be used to make soft hair puree, hair gel, shampoo, conditioner and skin care products.
The preparation method of lauryl polymethyl siloxane is generally synthesized by alkylation reaction, and the common method is to react polymethyl siloxane with lauryl chloride in an organic solvent to generate lauryl polymethyl siloxane.
When using lauryl methicone, you need to pay attention to some safety information. It has low toxicity, but should still be used with caution. Avoid inhalation, contact with skin and eyes. Wear protective gloves and goggles during operation to ensure adequate ventilation. If the skin or eyes are touched, rinse immediately with plenty of water and seek medical help.
In general, lauryl polymethyl siloxane is a commonly used cosmetic raw material with good properties and various uses, but it must comply with relevant safety operating regulations when used.
