Definitions
- the preparation of the anionic surfactant-containing mixture which Partial neutralization of the anionic surfactants in their acid form can be done in conventional mixers or stirred tanks.
- neutralization media come with all basic organic ones Substances, preferably the usual constituents of solid or liquid Detergents and cleaning agents are considered.
- liquid organic neutralization media used.
- the neutralization medium can be presented and the anionic surfactant in acid form or the anionic surfactants are added in acid form or vice versa.
- Preferred liquid organic neutralization media are amines, in particular Dimethylamine as well as mono-, di- and triethanolamine.
- alkanesulfonic acids which are obtainable from C 12 -C 18 alkanes by sulfochlorination and sulfoxidation and by subsequent hydrolysis or by bisulfite addition to olefins, and in particular the esters of ⁇ -sulfofatty acids, e.g. B. the ⁇ -sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
- Suitable alkyl sulfuric acids are the sulfuric acid monoesters from primary alcohols of natural and synthetic origin, especially from fatty alcohols, e.g. B.
