Methyl paraben CAS:99-76-3 Introduction:
H&Z® Methyl Paraben is mainly used as a bactericidal preservative for organic synthetic food, cosmetics and medicine, and also as apreservative for feed.
Methyl Paraben is a kind of milky white to yellowish brown powder, odorless and tasteless, easy to absorb moisture and agglomerate. It is a kind of non-ionic surfactant formed by the combination of sucrose and fatty acid. It is edible and harmless to human body.
Methyl Paraben is internationally recognized as a broad - spectrum high - efficiency food preservative, and a certain amount of preservative is added to cosmetics to prevent microorganisms from spoilage of cosmetics.
Methyl paraben CAS:99-76-3 Function:
Methyl paraben (Methyl p-hydroxybenzoate)is widely used as food additives and synthetic preservatives in cosmetics and personal care products, and in pharmaceutical formulations.
Methyl paraben is the most vital ingredient in Pharmaceutical Formulations & Cosmetic Products. It has been in use since 1924 for the last many decades due to its harmless properties. Its applications in Pharmaceuticals & Cosmetic Industry have been tried and tested and have been certified as totally harmless to Human Life by various Medical Universities.
H&Z® Methyl paraben has been recommended to be used in all formulations in the range of 0.1 to 0.5%. This in turn enhances the shelf life of products quite substantially without changing their chemical properties. Considering the very small quantity of methylparaben being used and the extension of shelf life of final formulated products being quite substantial indicates the importance of usage of methylparabens in Pharmaceuticals & Cosmetic Industries.
It is found to be very useful against Mold & Yeast and find wide applications in Food Industry. The expert panel of the Cosmetic Ingredients Review (CIR) has concluded usage of Parabens as safe in Cosmetics, Foods and Pharmaceutical Industries. It is also used as Preservatives in various Drug Formulations from Microbial Organisms.
