Methyl Paraben Sodium(Sodium Methyl Paraben),is the sodium salt form of methyl parabenand is generally used as apreservative. This compound is the water-soluble form ofmethyl paraben, making it particularly ideal for use inwater-based products.

Chemical Structure:

• Chemical formula: C₈H₉NaO₃
• IUPAC name: Sodium methyl 4-hydroxybenzoate
• Other names: Sodium methyl p-hydroxybenzoate, Sodium methyl paraben

Methyl paraben sodium is a form of methyl paraben bonded with asodium ion. This makes it morewater-soluble, allowing it to be easily used in water-based formulations.

Areas of Use:

1. Cosmetics and Personal Care Products:
   • Methyl paraben sodium is commonly used inshampoos,conditioners,skin creams,makeup products, and otherwater-based cosmeticandpersonal care products.
   • In water-containing formulations, it acts as apreservativeto inhibit microbial growth.
2. Pharmaceutical Industry:
   • Topical medicationsand somesyrups, as well as other water-based pharmaceutical formulations, also use it as apreservative. It is effective in preventing microbial contamination and extending product shelf life.
3. Food Products:
   • It can be used as apreservativein some food products. However, its use in food products is subject to stricter regulations in some countries.
