<p>Preparation of acylglycinate compound (I) comprises reacting glycine with fatty acid chloride compound (II) in water and in the presence of an alkali base compound, which provides the cation, but in the absence of an organic solvent at 30-35[deg] C, where the portion of the fatty acid chloride contains less than 2 wt.% of acyl group with 18 or more carbon atoms, related to the total amount of the used fatty acid. Preparation of acylglycinate compound of formula ((R 1>-NH-CH 2-C(=O)-O ->) Q +>) (I) comprises reacting glycine with fatty acid chloride compound of formula (R 1>Cl) (II) in water and in the presence of an alkali base compound, which provides the cation, but in the absence of an organic solvent at 30-35[deg] C, where the portion of the fatty acid chloride contains less than 2 wt.% of acyl group with 18 or more carbon atoms, related to the total amount of the used fatty acid.R 1>= saturated 6-30C (preferably 8-18C) alkanoyl group or one or more unsaturated 6-30C (preferably 12-18C) alkenoyl group; and Q +>= a cation of alkali metal including Li +>, Na +>(preferred) or K +>. An independent claim is included for a composition comprising: (a) 21-28 wt.% of one or more (I), where a portion of (I) comprises less than 2 (preferably 1.8) wt.% of acyl groups; (b) >= 1 wt.% of one or more chlorinated substances of formula (Q +>Cl ->) (III); (c) less than 2 wt.% (preferably greater than 0.1 wt.% and less than 2 wt.%) of one or more fatty acid salt of formula (R 2>-C(=O)-O ->Q +>) (IV); and (d) water, but devoid of organic solvent.
