How Does It Work:
Parabens have no color or smell. It has no taste, does not discolor, and is practically pH neutral. They exert a wide spectrum of antimicrobial activity, although they are most effective against moulds and yeasts.
Applications Or Where It Is Used:
A type of paraben is methylparaben. Parabens are chemical preservatives that give products longer shelf lives. Mold and other bacteria are prevented from growing on food or cosmetics by adding these chemicals.
Preparation of sodium methylparaben involves the following steps: firstly, adding methyl p-hydroxybenzoate to the reaction vessel, then gradually adding sodium hydroxide in an amount equivalent to 1.05 times methyl p-hydroxybenzoate, for one hour at room temperature.
How To Use:
Methylparaben is a form of paraben. Parabens are chemicals used as preservatives in beauty products to prolong product shelf life. Mold and other bacteria are prevented from growing on food or cosmetics by adding these chemicals.
