natrathix™ bio cellulose


Synthetic polymers have traditionally been used to modify rheology and stabilize skin care emulsions with appealing aesthetics, making it difficult to create the natural, sustainable formulations consumers want. Existing natural rheology modifiers typically have very poor aesthetics.

Committed to sustainable innovation, Ashland introduces natrathix™ bio cellulose, a nature-derived, biodegradable thickener with suspension capabilities that maintains emulsion stability of skin and sun care formulations while delivering a desirable skin feel. Developed through our market leading expertise in sustainably sourced cellulosics¹ and rheology modification, natrathix™ bio enables the creation of more natural skin care creams, lotions and gels, including organic and inorganic sunscreen formulations, with the texture, skin feel and sustainability that consumers demand.
