Usage
Used in cosmetics, pharmaceuticals and food industries as a broad-spectrum preservative and antimicrobial agent, effective against Gram-positive and Gram-negative bacteria, yeasts and molds. Among the paraben series, the butyl ester has the best oil solubility and strongest antimicrobial activity, widely used in creams, lotions, lipsticks, eye shadows, foundations and other oil-rich formulations, as well as in topical pharmaceutical preparations and feed preservation. Can be used alone or combined with other parabens for synergistic preservation. Recommended dosage: 0.2%–0.5%, applicable pH range 4–8.
