1,1,3,3-Tetraethenyl-1,3-dimethylpropanedisiloxane - Introduction

1,1,3, (also known as VEMD) is an organic silicon compound. The following is a description of its nature, use, preparation and safety information:

Properties: VEMD is a colorless liquid with low viscosity and low surface tension. Its chemical structure contains two siloxane groups and two methyl groups. VEMD is stable at room temperature and is not volatile.

Uses: VEMD is an important surfactant, widely used in cosmetics, personal care products, lubricants and polymers. It can improve the stability, lubricity and interfacial activity of the product, and enhance the cleaning ability of the detergent.

Preparation method: The preparation method of VEMD is more complicated, generally obtained by the reaction of hydrocarbons and silane compounds. The specific preparation process requires special equipment and conditions.

Safety information: VEMD is relatively safe under normal use conditions. However, it may be irritating to the eyes and skin, so use appropriate protective measures, such as wearing protective glasses and gloves. Avoid contact with strong oxidants and acids during operation and storage to prevent hazardous events. When disposing of waste, comply with relevant environmental regulations. In case of swallowing or contact accident, seek medical help immediately.
