Beauté by Roquette® ST 720 Starch

High power in curl retention thanks to our Beauté by Roquette® ST 720

After 7 hours, still 90% of curl retention with Beauté by Roquette® ST 720 at 5%.

The hold on hair is measured via a force required to break or snap the product film on the hair. A higher force indicates a higher hold:

*p value=0.0002 – Wilcoxon test

• Beauté by Roquette® ST 720 significantly provides a higher hold than without.
• Beauté by Roquette® ST 720 increases the fixing power of hair styling products.

The protective efficacy of Beauté by Roquette® ST 720 against heating stress (95°C for 20 min) was assessed on human hair shafts through the protection of hair proteins from oxidative damage (carbonylation).

Thanks to the use of Beauté by Roquette® ST 720 at 5% the protein oxidation is lower at both the cortex and cuticle level:

• - 59% of protein oxidation  protection on cuticle region
• - 50% of protein oxidation  protection on cortex region

Effective Barrier against Atmospheric Pollutants (In Vivo Evaluation)

Beauté by Roquette® ST 720 reduces the adhesion of black micro-particles: 2.3 times more efficient than the placebo.

T0= before the application of the cream
T1= after the application of carbon black
T2= after rinsing

Decreasing in skin adhesion of the Carbon Black micro-particles

*Natural origin index = Number of natural carbon atoms/Total number of carbon atoms (natural 14 & non natural)

Effective Barrier against Atmospheric Pollutants (In Vivo Efficacy)

Increasing in skin lightness (%) in the tested area.

In the area treated with Beauté by Roquette® ST 720, after rinsing, the black particles is decreased and the skin lightness (L parameter) is increased.
