Optiphen Plus, a paraben and formaldehyde-free preservative, is favored for its broad spectrum of bactericidal and fungicidal activity. It’s ideal for formulations that require a potent, globally approved preservative in a variety of personal care products. On the other hand, Germall Plus is a powerful, cost-effective, and highly compatible preservative, also offering a broad spectrum of anti-fungal and anti-microbial properties. Despite containing a small amount of a formaldehyde-releasing substance, it’s safe to use at recommended levels and works well in a wide range of formulations. The choice between these two depends on the specific requirement, formulation compatibilities, and legal guidelines of the product you are creating.

It’s commonly used as a food additive to inhibit the growth of molds and yeasts. Sorbic acid is also effective against bacteria and is often used in combination with other preservatives to enhance their activity. In Optiphen plus, sorbic acid complements the activity of phenoxyethanol, providing additional protection against spoilage organisms.

Caprylyl glycol is a moisturizing agent and emollient that’s widely used in cosmetic formulations, particularly in skincare products. It’s a natural fatty acid derived from coconut oil that’s excellent hydrating and skin-softening properties.
