Brief introduction
Alcohol-12 is a chemical also known as dimethicone/PEG-12 dimer. It is obtained by the chemical reaction of polydimethicone and polyethylene glycol (PEG).

Alcohol-12 has the following properties:
It is a colorless or yellowish liquid.
It has good solubility and can be soluble in water and many organic solvents.
It has good stability and high temperature resistance.
It has a certain surfactant ability and can be used as an emulsifier and a good wetting agent.

The method of preparing alcohol-12 is generally obtained by reacting dimethicone and polyethylene glycol under specific conditions. Specific methods include polymerization reactions and esterification reactions.

Safety information: Alcohol ester-12 is generally considered relatively safe and will not cause significant harm to human health when used reasonably. Like all chemicals, safe practices should be followed and excessive use should be avoided. If irritation or allergic reaction occurs, discontinue use immediately and consult a professional doctor.
