BASF launches a new active ingredient for skin care

BASF launches a new active ingredient that moisturizes, smoothes and soothes the skin: “Hydrasensyl” Glucan. These beneficial effects result from the active ingredient’s construction: its polysaccharide structure resembles hyaluronic acid, while the triple helix arrangement of the fibers is known from collagen.

Just like hyaluronic acid, which is often used in personal care products to hydrate and soothe the skin, this new active ingredient consists of a long chain of sugar molecules. This primary structure enables the active ingredient to act as a natural water storage, by binding large amounts of water. At the same time, the polysaccharide chains are intertwined to form a rope-like, highly resilient triple helix – just like collagen, a structural protein that gives the skin its elasticity. This 3D structure can help to enhance the resistance of formulations to variations in pH or temperature and electrolyte load. In addition, it  provides a pleasantly light feel on the skin.

Instantly and durably smooth, hydrated skin

In clinical studies, the ingredient has proven its rapid and exceptional efficacy: After two weeks of application at a dose of 2.5 percent, skin hydration went up by 43 percent and skin smoothness by 24 percent compared to the baseline. These effects even persist after discontinuing use: one week after stopping applications, the hydration rate and smoothness were still up 21 percent and 18 percent respectively. All the results were significantly better than the placebo.

Fast soothing effect

The active ingredient was also demonstrated to soothe skin irritated by UV exposure. The skin of volunteers was irradiated with 1.5 times the minimal erythema dose. The application of a gel with 2.5 percent of the new ingredient visibly reduced erythema intensity compared to control and placebo group. This new ingredient is derived from fermentation. A special proprietary BASF isolation and purification process enriches the β-glucan and maintains its specific functionality. The colorless, clear to opalescent viscous liquid is characterized by an exceptional purity of the high molecular weight beta-glucan.
