Product Introduction
Methyl 4-hydroxybenzoate, also known as Methyl Paraben, mainly used as antiseptic preservative for organic synthesis, food, cosmetics, medicine, and also used as feed preservative.
Methyl 4-hydroxybenzoate is an organic matter. Because of its phenolic hydroxyl structure, it has better antibacterial properties than benzoic acid and sorbic acid. The activity of paraben is mainly due to its molecular state, and the hydroxyl group in the molecule has been esterified and no longer ionized. Therefore, it has a good effect in the range of pH 3 to 8. It is a chemically inert substance and is easy to compatible with various chemical substances.
Product Feature
1.Stable performance;
2.There will be no decomposition or activity change under high temperature;
3.Easily compatible with various chemical substances;
4.Economical and long-term use.
Applications
It is used for the antiseptic of daily chemical washing (laundry liquid, shower gel, shampoo, detergent, etc.).
It is also used for antiseptic in feed, daily industrial products, equipment disinfection, textile industry (textile, cotton yarn, chemical fiber), etc.
