Overview
Ethyl Ester Water-soluble Preservative, commonly known as ethyl paraben, is a synthetic compound widely used for its antimicrobial properties. It is particularly effective in inhibiting the growth of bacteria, mold, and yeast, making it a popular choice in the food, cosmetics, and pharmaceutical industries. Its water-soluble nature allows for easy incorporation into aqueous formulations, enhancing its versatility. The compound is derived from the esterification of 4-hydroxybenzoic acid with ethanol, resulting in a stable and efficient preservative.
Physical and Chemical Properties
Ethyl Ester Water-soluble Preservative appears as a white crystalline powder with a molecular weight of 166.18 g/mol. It has a melting point range of 115-118°C and a density of 1.17 g/cm³. The compound is soluble in water, ethanol, and propylene glycol, which facilitates its use in various formulations. Its stability under normal conditions and resistance to hydrolysis make it a reliable preservative. However, it may degrade under extreme pH conditions or high temperatures, requiring careful formulation and storage.
Main Applications
The primary application of Ethyl Ester Water-soluble Preservative is in the food industry, where it is used to extend the shelf life of products such as beverages, baked goods, and dairy items. Its ability to inhibit microbial growth ensures product safety and quality. In the cosmetics industry, it is commonly found in creams, lotions, and shampoos to prevent spoilage. The pharmaceutical industry also utilizes it in topical medications and oral solutions to maintain sterility and efficacy.
Safety and Storage
While Ethyl Ester Water-soluble Preservative is generally regarded as safe for use in regulated concentrations, it is essential to handle it with care. Avoid inhalation and direct skin contact by using protective equipment such as gloves and masks. Storage should be in a cool, dry place away from direct sunlight to maintain stability. Proper labeling and segregation from incompatible substances are also recommended to prevent contamination and degradation.
B2B Procurement Guide
When procuring Ethyl Ester Water-soluble Preservative, B2B buyers should prioritize suppliers with verified certifications and a track record of quality. Key factors to consider include the CAS number (120-47-8), purity levels, and compliance with industry standards such as FDA or EU regulations. Price ranges typically vary between $20-$50 per kg, depending on quantity and purity. Bulk purchases may offer cost savings, but it is crucial to assess storage capabilities to prevent spoilage. Request samples for testing before large-scale orders to ensure compatibility with your formulations.
