Abstract
Detergent compositions contain a fatty acid bis (hydroxyalkyl) amide having a low content of the fatty acid monoesters of said amide normally associated therewith and which is prepared by holding at a temperature below 55 DEG C. for at least two days a molten mixture of said fatty acid bis (hydroxyalkyl) amide, a free bis (hydroxyalkyl) amine in an amount not more than 10% by weight (based on the molten mixture) in excess of that capable of reacting under the conditions of the reaction with any esteramide present in said initial mixture, and at least 0,05% by weight (calculated as alkali metal) of a catalyst consisting of an alkali metal, alkali metal hydroxide, alkali metal alkoxide, alkali metal amide or mixture thereof, so as to form a molten product containing at least 85% by weight of the fatty acid bis (hydroxyalkyl) amide. Other components present are sodium and triethanolamine dodecylbenzene sulphonates, ethanol and water, and the final phase may be liquid or solid.ALSO:A process for the preparation of a composition containing a fatty acid bis (hydroxyalkyl) amide having a low content of the fatty acid monoesters of said amide normally associated therewith comprises holding at a temperature below 55 DEG C. for at least two days a molten mixture of a fatty acid bis (hydroxyalkyl) amide, a free bis (hydroxyalkyl) amine in an amount not more than 10% by weight (based on the molten mixture) in excess of that capable of reacting under the conditions of the reaction with any esteramide present in said initial mixture, and at least 0.05% by weight (calculated as alkali metal) of a catalyst consisting of an alkali metal, alkali metal hydroxide, alkali metal alkoxide, alkali metal amide or mixture thereof, so as to form a molten product containing at least 85% by weight of the fatty acid bis (hydroxyalkyl) amide. The process is preferably carried out immediately subsequent to the preparation of the fatty acid bis (hydroxyalkyl) amide by amidation of the fatty acid ester with bis (hydroxyalkyl) amine at elevated temperatures such as 70 DEG C.-175 DEG C. The catalyst required for the amidation reaction may be the same as that required for the subsequent treatment and may be retained in the reaction mixture for such treatment. Preferred fatty acids are those having 10 to 18 carbon atoms. Preferred bis (hydroxyalkyl) amines are diethanolamine, di-isopropylamine, dibutanolamine and dipentanolamine. Examples describe the preparation and subsequent treatment of the N-bis (2-hydroxyethyl) amide of coconut oil fatty acid.
