乙酰氧基七甲基环四硅氧烷 - Introduction

It is also known as DMA4120 or acetate, which is an organic silicon compound. Its chemical formula is C12H28O5Si4, which has a colorless and transparent liquid state.

Ni has the characteristics of low viscosity and low pressure steam at room temperature, and can volatilize quickly. It has good thermal stability, electrical insulation and chemical resistance. In addition, it also has good interfacial activity and mirror gloss, and can be used as a solvent with excellent performance.

It is mainly used in cosmetics, medicine, paint and other fields. In cosmetics, it is often used in emulsifiers, thickeners, suspending agents, emollients, etc. In medicine, it can be used as a solvent or carrier to stabilize the drug in the drug delivery system. In coatings, it can provide excellent gloss and adhesion.

The preparation can be converted by reacting heptamethylcyclotetrasiloxane with acetic anhydride. The specific preparation method can be carried out in the laboratory or industrially.

When using the ball, pay attention to its safety. Due to its low vapor pressure, avoid prolonged exposure to high temperature environments to reduce volatilization. At the same time, care should be taken to avoid contact with strong oxidants and strong acids to avoid dangerous reactions. In the process of operation, should wear appropriate protective measures, such as wear protective gloves and goggles. If accidentally splashed into the eyes or skin, should immediately rinse with plenty of water, and medical treatment.

It is a widely used silicone compound, but it needs to be used with caution and comply with relevant safety regulations.
