Solubilizates of preservatives and method for producing the same

摘要

Described is a solubilizate of a preservative containing an aliphatic and/or aromatic acid such as sorbic acid and/or benzoic acid that is free of stabilizing agents, as well as one or more emulsifiers with an HLB value between 9 and 18 with a concentration of about 50% and about 95% emulsifier with regard to the total quantity of the solubilizate, and a procedure for the production of such a solubilizate.

1. A water-free solubilisate of a preservative containing benzoic acid that, but for the presence of one or more emulsifiers with an HLB value between 9 and 18, is free of stabilizing agents, with a concentration of about 50% and about 95% emulsifier (w/w) with regard to the total quantity of the solubilisate, wherein the acid is in protonated form, the solubilisate further comprising a surfactant comprising an oil containing predominantly medium chain triglycerides and a wax,
wherein the emulsifier is a polysorbate and the surfactant is present in the solubilisate with a concentration of about 2 to 10 wt. %, whereby about 3 to 10 wt. % fall upon the oil and about 1 to about 2 wt. % fall upon the wax.
