Reliable microbial protection for water-based formulas in a small trial size
Salimix MCI Preservative 30 ml is a broad-spectrum synthetic preservative designed to control bacteria, mold and yeast growth in water-containing formulations. It belongs to the Preservatives and Antioxidants category, which brings together ingredients used to keep finished products stable throughout their shelf life. The 30 ml size is best suited for home-based cosmetic making and trial batches, letting formulators test a new recipe before scaling up to larger production runs.
The main use of this preservative lies in water and water-oil emulsions: creams, lotions, gels, shampoos, conditioners, wet wipes, and liquid household cleaning products. It is also widely used in industrial water-based dispersion systems, including adhesives, latex paints and technical fluids, where preventing bacterial contamination during long storage periods is essential. This broad reach across cosmetic, paint and household chemical industries explains why preservatives of this type remain among the most searched and applied ingredients worldwide for aqueous formulas.
A typical usage rate ranges from 0.05 to 0.15 percent of the total formula weight, though the exact concentration should be adjusted depending on the composition and the required level of protection. The preservative is added during the cold phase, once the mixture has cooled below 40 degrees Celsius, since prolonged heat exposure can reduce the activity of its functional compounds. It performs across a wide pH range, making it compatible with most standard cosmetic and household formulations.
Salimix MCI blends well with other preservatives and antioxidants, allowing formulators to build combined protection systems. For broader antifungal coverage, it can be paired with Leucidal SF Max 10 ml, while formulas requiring additional emulsion stability often include Microcare CB Preservative 10 ml. For a more naturally positioned product line, part of the preservative load can be complemented with Preservative Naticide 100 ml while keeping overall protection reliable.
Store the preservative in a tightly closed container, in a cool dry place away from direct sunlight, avoiding temperature fluctuations. Under proper storage and correct dosing, the compound retains its stated effectiveness throughout the declared shelf life. Before introducing it into a new recipe, it is recommended to run a small trial batch and check stability after a few weeks at room temperature as well as under elevated temperature for an accelerated stability check.
Trial batch soothing facial mist
Distilled water 80 ml
Aloe vera juice 12 ml
Glycerin 3 ml
Panthenol 2 ml
Salimix MCI 0.12 ml
Combine distilled water with aloe vera juice and glycerin, stirring until fully blended, then add panthenol and mix thoroughly. Once the mixture has cooled below 40 degrees Celsius, add the preservative and stir until evenly distributed, then pour into a clean spray bottle. Let the mist rest for 24 hours before first use to allow the formula to stabilize.
