Description

Butylparaben CAS NO 94-26-8 is a synthetic organic compound belonging to the paraben family, widely recognized for its effective antimicrobial and preservative properties. Its primary value lies in its ability to inhibit the growth of mold, yeast, and bacteria, thereby extending the shelf life of a diverse range of products. This makes it a critical ingredient for manufacturers in the personal care, cosmetics, pharmaceutical, and food industries seeking reliable and cost-effective preservation solutions.

Application

• Primary preservative in cosmetics and personal care products such as creams, lotions, shampoos, and makeup.
• Antimicrobial agent in pharmaceutical formulations, including topical ointments and some liquid preparations.
• Food preservative (where permitted by regulation) to prevent spoilage in items like baked goods, beverages, and processed meats.
• Industrial preservative in adhesives, glues, and industrial coatings to prevent microbial degradation.
• Component in animal feed additives to maintain hygiene and stability.
