Description

Peg-3 Dipalmitate CAS NO 32628-06-1 is a non-ionic surfactant and emollient ester derived from polyethylene glycol and palmitic acid. This compound is valued for its excellent emulsifying properties, skin conditioning effects, and ability to enhance the texture and stability of formulations. It is primarily needed by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating creams, lotions, and ointments.

Application

• As a primary or co-emulsifier in oil-in-water (O/W) creams and lotions for personal care.
• As a skin-conditioning agent and emollient to improve the smoothness and spreadability of cosmetic products.
• As a formulation aid in pharmaceutical topical preparations, enhancing drug delivery and product stability.
• As a viscosity modifier and stabilizer in various cosmetic emulsions.
• In hair care products such as conditioners and styling creams to provide softness and manageability.
• As a component in sun care products, helping to stabilize UV filters and improve product feel.
• In decorative cosmetics like foundations and BB creams for texture enhancement.
