Q1: What is BASF Emulan OK5 Emulsion primarily used for?
A: Emulan OK5 is a non-ionic O/W emulsifier specifically developed for stabilizing oil-in-water emulsions in personal care and cosmetic formulations, such as creams, lotions, and after-sun products. It supports elegant texture, good spreadability, and long-term physical stability.
Q2: Is Emulan OK5 suitable for sensitive skin applications?
A: Yes — Emulan OK5 is formulated to be mild and compatible with a broad range of active ingredients and preservatives. Its non-ionic nature and low irritation potential make it well-suited for gentle, dermatologically tested formulations, including those intended for sensitive or baby skin.
Q3: How should Emulan OK5 be incorporated into a formulation?
A: It is typically added to the aqueous phase and heated to 70–80 °C before combining with the oil phase. Emulsification proceeds efficiently under moderate shear. Pre-dispersion in water or co-solvents may improve handling in cold-process systems.
Q4: Can Emulan OK5 be used in combination with ionic surfactants?
A: Yes — Emulan OK5 demonstrates good compatibility with common anionic, cationic, and amphoteric surfactants. This allows formulators to build hybrid emulsifier systems for enhanced performance, such as improved viscosity control or sensory benefits, without compromising stability.
