Preservative blends
Preservative blends protect cosmetics and household products from bacteria, yeast and mould, including paraben-free systems suited to modern formulations.
Any product that contains water can grow microorganisms. Preservatives prevent spoilage and protect consumers during the product's life, including after opening. Blends combine actives with complementary strengths so a single system covers bacteria, yeasts and moulds across the formula's pH.
Common paraben-free systems include phenoxyethanol with ethylhexylglycerin, organic acids such as sodium benzoate and potassium sorbate for products below about pH 5.5, and isothiazolinones for rinse-off and household products. Each active has a maximum permitted level that differs by market and product type, so the blend is chosen with regulation in mind.
