Abstract: A cosmetic composition comprising one or more ether carboxylic acids and one or more non-ionic surfactants, method for the preparation of the cosmetic composition, and method for use of the cosmetic composition for the cleansing of skin and/or hair.

Abstract: The present invention relates to a process for obtaining amidated fatty acids or derivatives thereof good in color even after longer storage with low concentrations of undesired by-products. The present invention also relates to use of amidated fatty acids or derivatives thereof obtained by the process in the cosmetic applications. Further, the present invention also relates to use of amidated fatty acids or derivatives thereof obtained by the process in the industrial applications.

The present invention also relates to the method for the preparation of the cosmetic composition, as well as to the use of the cosmetic composition for the cleansing of skin and/or hair.

Abstract: A mixture of amides of the following formula (I) is disclosed wherein —R1 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms; —R2 and R3 represent independently, a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms which is optionally hydroxylated, provided that R2 and R3 are not a hydrogen atom at the same time; -n has a value in the range of 0.2 to lower than 3; characterized in that said mixture comprises: -amides (a) of formula (I) wherein R represents a C6-C24 alkyl or alkenyl group having even number of carbon atoms and at least a 95 wt. % of linearity; and -amides (b) of formula (I) wherein R represents a C5-C23 alkyl or alkenyl group having odd or odd and even number of carbon atoms and a 35-85 wt. % of linearity; and cosmetic compositions comprising said mixture, particularly dying compositions.
