SNF presents Natursol Bioseven, a biodegradable cationic polymer for foaming hair and body formulations, introduced at in-cosmetics 2026 and designed for integration into existing wash bases.
SNF presented Natursol Bioseven at in-cosmetics 2026. The product is presented as a new-generation cationic polymer developed for foaming rinse-off applications, in particular shampoos and shower gels.
Positioning and environmental profile
Natursol Bioseven is presented as an alternative to the polyquaterniums used in shampoos and shower gels.
The polymer achieves a biodegradability level of over 60 % in 28 days according to OECD 301F, a parameter mentioned as relevant for raw material selection.
The substance is patent-protected and has been developed to meet today's formulation constraints, notably compatibility with a wide range of surfactant systems and robustness to industrial process conditions.
Functional properties and formulation compatibility
Designed for foaming systems, Natursol Bioseven delivers the functional benefits cited for hair and skin applications: improved detangling, especially on fine hair, without build-up.
On the skin, the polymer contributes to a soft feel after rinsing.
It supports the formation of fine, dense and stable foam.
The polymer can be incorporated into a variety of cleansing bases (shampoos, shower gels, facial cleansers) and has good tolerance to pH variations and electrolytes, making it easy to integrate into existing formulations.
Natursol Bioseven is a liquid, cold-processable solution designed to be intuitive to use and compatible with standard manufacturing processes.
