Sodium methylparaben is a modified paraben antimicrobial agent optimized for water-based formula systems. Compared with common paraben monomers, this salt-form product greatly enhances water solubility and can be perfectly dissolved in purified water and ethyl alcohol, yet incompatible with oily ingredients and ether. The raw material owns stable chemical properties under conventional storage and production conditions. It performs stably in neutral and weakly alkaline aqueous formulas and tolerates routine production heating. Nevertheless, contact with strong acid will lead to ingredient precipitation and loss of preservative efficacy, which should be avoided in formula design and raw material storage.
Key Advantages
Featuring comprehensive antibacterial and antifungal properties, sodium methylparaben effectively suppresses various microorganisms including bacteria, mold and yeast, providing long-lasting and stable preservative effects for water-based finished products.
The water-soluble formula eliminates the need for organic solubilizers, streamlining factory production procedures and solving the problem of solvent residue and product irritation.
With excellent system compatibility and heat resistance, it adapts to diversified formula types across daily chemical, food and pharmaceutical industries.
All product batches comply with official ingredient specifications, ensuring mild, safe and non-irritating application within standard usage dosage.

Applications
Widely used in fine chemical, food and pharmaceutical industries, sodium methylparaben acts as a high-efficiency antibacterial preservative for water-based products. In personal care fields, it is widely used for aqueous skincare and cleansing supplies such as toners, essence water and toothpaste, complying with local cosmetic regulatory requirements. In food processing, it preserves liquid drinks, sauce condiments and other fluid foods to prevent spoilage and meet national safety standards. Furthermore, it is a common auxiliary preservative for pharmaceutical external solutions and daily water-based detergents, effectively inhibiting bacteria and extending product shelf life.
Packaging & Storage
Standard commercial packaging adopts 25kg lined paper drums with double food-grade inner plastic bags, and flexible custom packaging is supported for bulk orders.
To maintain stable product quality, store the goods in dry, shaded and ventilated indoor environments.
