Selbstkonservierende flüssige Tensidsysteme.

摘要

The invention relates to the use of water-soluble alkali metal, alkaline earth metal or aluminium salts, which are compatible with surfactants without precipitation, of inorganic or organic anions in an amount of at least 2% by weight, preferably at least 5% by weight (calculated as anhydrous salt), for preserving preservative-free, liquid, water-containing surfactant systems containing 2-50% by weight, preferably 5-35% by weight, of one or more surfactants. Particularly effective, preservative-free, self-preserving, liquid, water-containing surfactant systems, especially a shower gel, are disclosed.
