Dodecyl Sulfate (SDS) and then treated to damage them. The oligofurcellaran was applied at 1% and massage was done for one minute. Then hairs were rinsed with water for 30 seconds, and dried in open air. Sound measurement of the hair was done
using a device equipped with a comb attached to a cylindrical mixing blade. The number of rotations and speed (rpm) can be controlled. The comb is equipped with a sound sensor to record the sound during combing. The entire system was set up in an anechoic chamber. Ten hair strands were put into the machine one after the other and each strand combed ten times. Different sound parameters were extracted
for each hair strand reflecting the condition of the hair, such as average amplitude (in dB) and duration (in seconds). The amplitude should fall when the hairs are repaired (intensity) and the shorter is the duration, the smoother is the hair. The test clearly showed that treatment with
the oligofurcellaran reduced the amplitude of the sound (by 11%) and the duration (by 31%). Figure 8 shows an example of recording without and with the oligofurcellaran, showing the reduction of both sound intensity and duration of untangling. Lastly, a new study has recently showed that the oligofurcellaran can also be an interesting

agent for the protection of hair against carbonylation.4
This effect was also noted for
nails protection against carbonylation using a recently described method.5
Conclusion Today’s consumers expect products to be safe, effective, and sustainable. We all know, we have one planet earth, and we must respect the resources we use. Hence, sustainability, encompassing environmental and social aspects, is a driving force in the beauty industry, without compromising product effectiveness and quality. Est-Agar and Codif Technologie Naturelle both specialize in innovation across all those fronts to disrupt the beauty industry. Red seaweed, being entirely natural, aids in
reducing aquatic toxicity by safeguarding our waters and marine life from artificial cosmetic ingredients and plastics. Furcellaria lumbricalis extract manufactured by Est-Agar can imbue your beauty and personal care products with creaminess, smoothness, and a uniquely soft texture with additional bioactive compounds. High technological furcellaran concentrate
created by Codif Technologie Naturelle significantly enhances furcellaran bioactive compounds. Codif has developed Hydranov, a smart and effective moisturizer with hyaluronic
acid effect for for skin care, and Capiguard for hair care, fighting against pollution and protecting the hair cuticle.
