1.4 PRODUCT SHORT DESCRIPTION
Cosphaderm® Sodium LAAS is a white powder comprising the solid mixture of Sodium Levulinate and Sodium Anisate. This blend displays skin conditioning and masking properties, as well as a broad antimicrobial effectiveness. This way, Cosphaderm® Sodium LAAS can help to ensure a formulations microbiological stability without the use of traditional preservatives.
The corresponding acids of both salts show a strong combined antimicrobial efficiency against bacteria, yeasts and moulds. The lower the pH value of the final formulation, the more the balance between salts and acids is shifted to the latter. Thus, it is essential to consider the pH of the formulation when using Cosphaderm® Sodium LAAS. Application within a pH range from 5.0 – 6.0 is possible, though 5.5 is ideal. Below a pH of 5.0, precipitation can occur, while above 6.0 the antimicrobial activity is diminished.

1.5 APPLICATION
Recommended concentration: 1.0 % (complete antimicrobial protection)
Conditions: water soluble
Hints: Add recommended concentration to the water phase of your formulation. Reduce the pH value at the end of your formulation to 5.0 – 6.0, ideally 5.5.
