BASF debuts Kerasylium, a plant-based alternative to animal keratin

From Premium Beauty News

At the in-cosmetics Global trade show in Barcelona, BASF Personal Care has launched an upcycled plant extract with an amino acid composition similar to that of keratin to help repair damaged hair and protect it from daily aggressions.

BASF’s new hair care ingredient is a micro-complex, rich in peptides and nutrients. Dubbed Kerasylium, the plant extract is the result of upcycling from milk thistle (Silybum marianum) seed cakes, a by-product of Silybum marianum oil production.

Sustainable upcycled plant extract
Kerasylium’s peptides exhibit an amino acid composition similar to that of keratin, a protein naturally present in the hair, which ensures its resistance and elasticity.

“Many cosmetic manufacturers rely on keratin for their hair care products because it helps to repair the hair from the inside out. However, the keratin-based ingredients that are usually used in hair treatments are of animal origin. We wanted to change that, so we developed Kerasylium, a plant-based alternative,” said Cécile Kalem, Launch Manager Europe, BASF Beauty Care Solutions France S.A.S.

Kerasylium expands BASF’s growing portfolio of active ingredients produced via circular models to conserve resources. The milk thistle used is grown in France for oil production and is based on a traceable and sustainable supply chain.

Assessed efficacy
Thanks to its high peptide content (50-70% of the active matter), Kerasylium helps to prevent breakage, especially of weakened hair, through the stabilization and repair of hair keratin, making hair stronger, shinier, and softer.

Moreover, comprehensive studies have shown that Kerasylium decreases keratin denaturation by protecting the structural proteins of the hair against oxidative stress, while helping to maintain its color for longer.
