Protective action
HydamerTM HCMF and PVP/VA copolymers both form films of comparable hardness after drying. However, varying properties can be observed in these films. While cracks develop in PVP/VA films during drying, HydamerTM HCMF forms a homogeneous, stress-free film.
There is no visible difference in Hydamer HCMF’s performance even after 10 times combing. Excellent for a styling without flaking.

Crack formation in PVP/VA films can ecounteracted by adding small amounts of HydamerTM HCMF. A mixing ratio of 1:0.05 is sufficient to bring about a considerable reduction in crack formation. A mixing ratio of 1:0.1 results in films that are absolutely homogeneous and dry without cracking. HydamerTM HCMF enhances film elasticity and prevents polymer films from drying out and cracking.

Splitting ends
Another test involves simulated splitting under in-vitro conditions. Treatment with a rinse containing 0.5% HydamerTM HCMF remarkably reduces the rate of splitting. This is a vivid illustration of Chitosan’s protective action and proves that HydamerTM HCMF is qualified to prevent split ends. On top of that, a single rinse with a product containing 0.5% HydamerTM. HCMF revealed the agent’s significant repair effect.
