Andrézieux, France – In a context where conventional cationic polymers are increasingly being reassessed, SNF is introducing NATURSOL BIOSEVEN, a new-generation polymer designed for rinse-off applications, combining conditioning performance with an improved environmental profile.
An alternative to conventional polyquaterniums
NATURSOL BIOSEVEN is positioned as an alternative to polyquaterniums commonly used in shampoos and shower gels. The polymer exhibits a biodegradability level exceeding 60% within 28 days (OECD 301F), a parameter that is gaining importance in raw material selection.
Protected by patent, it has been developed to meet address current formulation constraints, particularly in terms of compatibility with a wide range of various surfactant systems and robustness under industrial processing conditions.
Functional properties
Designed for foaming systems, NATURSOL BIOSEVEN provides the functional benefits expected in hair and skin care applications:
- Hair conditioning: improved detangling performance, particularly on fine hair, without build-up
- Skin feel: contributes to a soft after-feel following rinsing
- Foam quality: supports the formation of a fine, dense and stable foam
The polymer can be incorporated into various cleansing bases (shampoos, shower gels, facial cleansers), showing good tolerance to pH variations and electrolytes, thereby facilitating its integration into existing formulations.
Formulation compatibility and application scope
NATURSOL BIOSEVEN has been designed for ease of implementation, with compatibility with standard manufacturing processes. Its versatility allows formulators to consider its use across a wide range of product concepts, including formulations integrating sustainability criteria or meeting enhanced environmental requirements.
Addressing evolving market requirements
With NATURSOL BIOSEVEN, SNF continues to develop polymers combining in-use performance and biodegradability. This innovation reflects a broader industry trend, as formulators seek to balance technical efficiency, consumer experience and reduced environmental impact.
