Methylparaben /Methyl 4-hydroxybenzoate
Purity:99%
CAS:99-76-3
MF:C8H8O3
Package:25kg/bag
Methylparaben is a colorless crystalline powder with a faint characteristic odor and a slight burning taste. It is slightly soluble in water but easily dissolves in ethanol, ether, acetone, and other organic solvents.
| Cetylpyridinium chloride Chemical Properties |
| Melting point | 77°C |
| Boiling point | 496.25°C (rough estimate) |
| density | 0.9362 (rough estimate) |
| vapor pressure | 0Pa at 25℃ |
| refractive index | 1.6000 (estimate) |
| storage temp. | Inert atmosphere,Room Temperature |
| solubility | Freely soluble in water; very soluble in chloroform; very slightly soluble in ether; insoluble in acetone, acetic acid, and ethanol. |
| form | White Crystalline Powder |
USE:
Methylparaben is an antimicrobial agent which is a white free-flowing powder. it is active against yeast and molds over a wide ph range. see parabens.
Methylparaben and propylparaben are the most common of these. parabens is one of the most commonly used group of preservatives in the cosmetic, pharmaceutical, and food industries. Parabens provide bacteriostatic and fungistatic activity against a diverse number of organisms, and are considered safe for use in cosmetics, particularly in light of their low sensitizing potential.
