Description
Liquid Germall Plus – Broad-Spectrum Cosmetic Preservative
Liquid Germall Plus is a highly effective, broad-spectrum liquid preservative designed to protect cosmetic formulations from Gram-positive and Gram-negative bacteria, yeasts, and molds, without needing any additional boosters. It delivers reliable antimicrobial performance at very low use levels and is compatible with virtually all cosmetic ingredients, making it one of the most versatile and cost-efficient preservatives available.
This preservative works seamlessly in cationic, anionic, and nonionic systems, and performs exceptionally well in water-in-oil and oil-in-water emulsions, lotions, creams, make-up formulations, and other high-pigment products. It is also suitable for surfactant-rich systems such as shampoos, shower gels, and conditioners. Not recommended for aerosol products.
Liquid Germall Plus should be added during the cool-down phase, at 40°C (104°F) or below, as higher temperatures can compromise its efficacy.
