Description

Polawax A 31 is a high-purity, non-ionic emulsifying wax widely recognized for its exceptional stability and versatility in creating elegant, stable emulsions. Its primary value lies in its ability to form robust, fine-textured creams and lotions without the need for complex co-emulsifier systems, simplifying formulations and enhancing batch-to-batch consistency. This makes it an indispensable ingredient for manufacturers in the cosmetic, pharmaceutical, and personal care industries seeking reliable performance in products ranging from moisturizers and ointments to topical drug delivery systems.

Application

• Primary Emulsifier in oil-in-water (O/W) creams, lotions, and ointments for cosmetic and pharmaceutical use.
• Stabilizing Agent for topical formulations, preventing phase separation and ensuring elegant texture and spreadability.
• Base Component in cold-process formulations, allowing for efficient production without the need for heating.
• Key Ingredient in anhydrous systems that are later emulsified with water, such as cleansing balms.
• Pharmaceutical Creams, including hydrocortisone creams and antibiotic ointments, where formulation stability is critical.
• Hair Care Products, such as conditioning creams and anti-frizz serums, providing emulsification and conditioning benefits.
• Sunscreen Formulations, helping to stabilize UV filters within the emulsion for consistent SPF performance.
