Developed exclusively for water-based formulation systems, sodium ethylparaben stands out for its superior hydrophilic performance. It dissolves instantly in regular-temperature water and mixes well with polar organic solvents, while failing to dissolve in oily substances and ether-based non-polar solvents. This paraben salt derivative features stable chemical traits under conventional storage and manufacturing conditions. It can withstand high-temperature production processes and keeps stable antibacterial potency in neutral and weakly alkaline formula environments. Notably, acidic conditions with low pH values will trigger raw material precipitation, which disables the product's preservative and antibacterial functions.
Key Advantages
In addition, the product has low impurity content and complete qualification certification, ensuring mild, non-irritating and safe application in compliant dosage.
Equipped with comprehensive antimicrobial properties, sodium ethylparaben efficiently suppresses the proliferation of various harmful microorganisms in water-based products.
Compared with ordinary aqueous preservatives, it provides more durable and stable anti-corrosion protection for finished goods.
Featuring convenient water solubility, the raw material requires no additional organic solubilizers, greatly optimizing production workflows and eliminating hidden dangers such as solvent residue and product irritation.
It achieves high compatibility with water-based skincare products, daily detergents, liquid food and pharmaceutical preparations without altering finished product properties.

Applications
Covering multiple downstream industries, sodium ethylparaben is a universal antibacterial preservative for water-based finished products. It is widely used in various aqueous personal care products such as toners, essences, bath and hair care products, as well as toothpaste and water-based masks, satisfying daily cosmetic antiseptic demands. For food manufacturing, it effectively preserves various liquid beverages and seasoned liquid foods, preventing microbial spoilage and complying with national food safety standards. Besides consumer goods, it is also an ideal preservative choice for pharmaceutical external preparations, skincare treatment solutions and daily water-based cleaning supplies.
Packaging & Storage
Standard commercial packaging adopts 25kg lined paper drums with double food-grade moisture-proof inner bags for tight sealing, and flexible custom packaging services are supported for diverse order demands.
To preserve stable product quality, raw materials should be stored in dry, shady and ventilated indoor environments, far away from heat sources, strong sunlight and reactive chemical materials including acids, alkalis and oxidants. Given its hygroscopic nature, airtight storage is mandatory at all times to avoid caking and quality degradation.
