Texture Must Be Just Right: It is the first rule of cosmetic chemistry. Personal care products must be formulated with meticulous care and maintain their signature look and feel over time. Plasticizers can be an essential component in both creating texture and helping to maintain your formula's stability over time.

Adding Flexibility in Texture

Kester Wax K-70P is Koster Keunen's star plasticizer for imparting desirable attributes to squeezable systems, without affecting structure. Naturally derived from Rice Wax, Kester Wax K-70P increases ease of processing by enhancing crystallization control- while helping you respond to the market preference away from parabens and phthalates. Enhancing the elastic character of products that include Kester Wax K-70P means that your squeezables maintain cohesive structural integrity, and to consumers that means your systems perform to the standards they expect from your range. Textures stay creamy and stable.

Showing off Effective Formulation

A natural plasticizer, Kester Wax K-70P contributes generously in formulation. In addition to creating a creamy texture, especially for squeezable systems, plasticizers excel at keeping actives and color suspended in the gel matrix, so personal care products deliver their chief benefits with every squeeze.
