PRESERVASOL 1 L

Ensuring Consistent Microbial Protection for Cosmetic Formulas at Scale

When a production line moves beyond small batches into continuous manufacturing, microbial stability of every single lot becomes non-negotiable, and the 1 liter package of PRESERVASOL Preservative is built exactly for that stage of growth. This item belongs to the Preservatives and Antioxidants category, which brings together substances responsible for keeping finished formulations free from bacterial, yeast and mold contamination throughout their entire shelf life on the shelf and after opening. Without a reliable preservative system, even a well-balanced emulsion or gel can turn into a breeding ground for microorganisms within weeks of first use.

The primary field of application for PRESERVASOL is water-based cosmetic systems - facial and body creams, lotions, shampoos, conditioners, shower gels, and water-phase color cosmetics. Beyond skin and hair care, the preservative is widely used in household chemical products such as liquid dish soaps, fabric softeners and cleaning solutions, where residual water content creates a real risk of contamination without proper protection. The active compounds deliver broad-spectrum activity against gram-positive and gram-negative bacteria as well as yeast and mold, making this preservative a practical choice for the majority of water-based and water-oil emulsion systems used across industries.

For best results, the preservative should be added during the final stage of production, once the base emulsion has already formed and the mixture has cooled to 40 degrees Celsius or below - this protects the active substances from thermal degradation and preserves their full protective capacity. Typical usage levels fall between 0.5 and 1 percent of total formula weight, though the exact dosage depends on the pH of the system, water content and the intended shelf life of the finished product, so running a microbiological challenge test on each new formula before full-scale production is strongly advised.

For manufacturers working with large volumes, the 1 liter format of PRESERVASOL supports stable, predictable supply without frequent reordering or batch-to-batch quality fluctuations, which matters greatly for conveyor-line production and contract manufacturing of cosmetic goods. The preservative pairs well with antioxidants that protect the oil phase from oxidation, and it can be combined with other protective systems - for example, with Preservative Nipaguard CMB to broaden the spectrum of activity in complex multi-phase systems, or with NIPAGUARD SCE, often chosen for formulas designed for sensitive skin. Labs that want to verify compatibility with a new formula before committing to a full liter can start with the smaller PRESERVASOL Preservative 10 ml for trial batches.

The preservative should be stored in a tightly sealed container, in a dry area at room temperature, away from direct sunlight and heat sources, to prevent premature loss of activity. Once opened, the container should be used within the period specified by the manufacturer, keeping moisture and contaminants out during every withdrawal of product.

Lightweight Hydrating Face Lotion

Distilled water 680 ml

Plant-based emulsifier 50 g

Squalane oil 60 g

Jojoba oil 40 g

Glycerin 35 g

Aloe vera extract 40 ml

PRESERVASOL Preservative 10 ml

Fragrance oil 5 ml

Heat the water phase with glycerin and aloe extract to 75 degrees Celsius, and separately melt the oil phase with the emulsifier and oils to the same temperature, then slowly pour the oil phase into the water phase while stirring continuously until a smooth emulsion forms. Cool the mixture down to 40 degrees while stirring, add the preservative and fragrance, blend for a few more minutes, and pour the finished lotion into clean containers.
