What a small preservative volume tells you before scaling up a formula
Sepicide HB, 10 ml is a broad-spectrum preservative designed to protect water-based and water-oil cosmetic formulations against bacteria, yeast and mold growth. This compact volume works well for anyone testing a new cream, serum or emulsion before moving into batch production, and for small studios where precise dosing without wasting raw material really matters. The item belongs to the Preservatives and Antioxidants section, which brings together solutions for keeping finished products stable throughout their shelf life.
The main field of use for this preservative is skincare and haircare: creams, lotions, gels, serums, facial and body emulsions, hair conditioners and masks. It also appears in wet wipes, water-based sanitizing gels and certain household chemical formulas where a mild yet reliable protection system is needed. Thanks to its stability across a fairly wide pH range, the ingredient pairs well with most active substances used in formulations — plant extracts, vitamins, oils, emulsifiers and surfactants found in shampoos and body washes.
A typical usage rate falls between 0.3 and 1 percent of the total formula weight, though the exact concentration should be adjusted based on the specific product composition and its expected shelf life. The preservative is added during the cooling stage, once the emulsion has dropped to around 40-45 degrees, which prevents the active complex from breaking down when exposed to a hot phase. After adding it, the batch should be mixed thoroughly until fully uniform, avoiding overheating.
For formulas that require a broader protection spectrum or an alternative mechanism, formulators often combine this preservative with other systems. LekoGuard BDBS Green works well for products with a natural positioning, while Naticide is often chosen as a gentle alternative for sensitive formulations. If the recipe is built on a plant-based concept and a wider protective spectrum is needed, Leucidal Liquid SF is worth considering — combining several protective systems lowers the risk of microbial adaptation and gives a broader overall defense.
Store the preservative in a tightly closed container, in a dry cool place away from direct sunlight, at room temperature and away from heat sources. Once opened, use the content within a reasonable time frame, avoiding contact with moisture and contamination to keep the declared efficacy for the full stated shelf life.
The 10 ml pack size is particularly convenient for lab trials, home-based formula development and small pilot batches, where several formula variants need to be tested before choosing the final composition for larger scale production.

Heat
the water and glycerin to 70 degrees, separately melt the oil with the
emulsifier 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 40-45 degrees, blend in the panthenol and the preservative,
stir until fully dissolved, then transfer the lotion into a clean, sealed
bottle for storage.
