Cosphaderm® Sodium LAAS is a water-soluble mixture of sodium anisate and sodium levulinate with a strong antimicrobial effect against bacteria, yeasts and moulds as well as skin-caring properties.
The corresponding acids (levulinic acid and anisic acid) have been tried and tested for decades, as they are very mild and well tolerated despite their strong effectiveness and versatility. However, a major disadvantage of the acids is their poor solubility in water. Although an aqueous mixture of glycerine, water, sodium levulinate and sodium anisate has been available for a long time and is easy to incorporate into the water phase, it has a number of disadvantages. The concentration of active ingredients is low and the mixture also contains a polyol (glycerine), which is often made from palm oil.
Product advantages
Cosphaderm® Sodium LAAS combines for the first time the advantages of acids with 
of the aqueous mixture (Fig. 1): The water solubility is 15 times higher than the recommended application concentration. This makes it extremely user-friendly. The ecological footprint is therefore significantly smaller. Compared to the aqueous mixture, the concentration of active substances is 400 % higher. This reduces the application concentration to ¼, storage and packaging costs are lower and it protects the environment. There is no need for a solubilising polyol, so Sodium LAAS is guaranteed palm oil-free.
It is the small details that make Cosphaderm® Sodium LAAS innovative. In order to prevent the two salts from separating (paranus effect due to inhomogeneous particle sizes), Cosphaderm® Sodium LAAS is produced in a spray-drying process. This means that each individual particle consists of the perfect mixture and segregation is impossible.
It is very easy to use. 1 % Cosphaderm® Sodium LAAS into the water phase, continue the formulation and adjust the pH value in the final step. There are no restrictions. Cosphaderm® Sodium LAAS can be used in emulsions, lotions, shampoos, shower gels, deodorants, face masks, decorative cosmetics and household products. Its very high compatibility makes it the ideal solution for sensitive skin and baby products. Neither ingredient is listed as a preservative in the European Cosmetics Regulation, nor is its use concentration limited.
