Optiphen ND Preservative 1 kg

What Makes Optiphen ND a Practical Choice for Bulk Cosmetic Manufacturing

Optiphen ND is a broad-spectrum preservative developed to protect water-based cosmetic formulas from bacteria, yeast and mold without relying on formaldehyde or parabens. This ingredient belongs to the section Preservatives and Antioxidants, which brings together solutions for extending shelf life in emulsions, gels, lotions and other water-containing products. The 1 kg pack size is aimed at studio and industrial production lines that need a consistent, predictable batch of raw material instead of frequent small purchases.

The main application of Optiphen ND lies in skincare manufacturing: creams, emulsions, toners, serums, baby care lines and intimate hygiene products. The compound remains stable across a wide pH range and performs well in formulas containing plant extracts, hydrolats and oils without causing separation or instability. It is also widely used in water-based household chemistry, including dish soap, liquid hand soap and cleaning solutions, where microbial control matters during long storage and transportation.

The preservative is typically added during the cooling phase of an emulsion, at temperatures below 40 degrees Celsius, to avoid breaking down active molecules through overheating. Recommended usage generally ranges from 0.5 to 1.5 percent of the total batch weight, depending on the formula and water phase ratio. Before scaling up a production run, it is advisable to test a small trial batch and monitor product stability over several weeks, especially when new botanical ingredients are introduced.

Optiphen ND combines well with other antimicrobial systems, allowing formulators to build layered protection for complex multiphase products. For instance, pairing it with Geogard Ultra Preservative can strengthen protection in formulas rich in organic extracts, while smaller trial batches often benefit from testing alternatives such as Rokonsal KS 4 or PRESERVASOL Preservative before committing to a bulk purchase. This step-by-step approach reduces risk when launching a new product line.

Store the preservative in a tightly sealed container, in a dry, cool place away from direct sunlight, at room temperature. When storage conditions are respected, the product retains its declared properties throughout the stated shelf life. The 1 kg format suits labs and production facilities running batches of several dozen liters, where a stable, repeatable supply of raw material over time is essential.

Heat the water and oil phases separately to 70 degrees Celsius, then slowly pour the oil phase into the water phase while stirring continuously until a uniform emulsion forms. Once the mixture cools to 40 degrees, add the glycerin, fragrance oil and Optiphen ND, mix thoroughly until fully blended, and pour into prepared containers.
