Abstract
The present invention relates to cosmetic cleaning agents containing surface-active betaines of the formula. ##STR1## wherein R.sup.1 and R.sup.2 are aliphatic hydrocarbon radicals having 1 to 18 carbon atoms and/or hydrogen and the sum of the carbon atoms in R.sup.1 and R.sup.2 is 9 to 18; R.sup.3 and R.sup.4 are the same or different and are lower alkyl or alkylol groups having 1 to 4 carbon atoms, x is an integer of 2 to 4, y is either 0 or 1, and z is an integer of 1 to 4; as well as their application as cleaning agents, for example, in hair washing and bathing preparations.
Claims17
A cosmetic cleaning agent, comprising an acid neutralized derivative of a surface-active betaine of the formula ##STR11## wherein R.sup.1 and R.sup.2 are the same or different and are alkyl radicals of 1 to 18 carbon atoms, provided that the sum of the number of carbon atoms of R.sup.1 and R.sup.2 is 9 to 18;
- R.sup.3 and R.sup.4 are the same or different and are lower alkyl or alkylol groups of 1 to 4 carbon atoms;
- x is an integer of from 2 to 4;
- y is 1;
- and z is an integer of from 1 to 4;
- and an anionic surfactant in a quantity of from 5 to 30 percent by weight, relative to the total weight of the agent;
- and a carrier therefor.
A process for cleaning the hair and skin of warm-blooded animals comprising topically applying to said hair and skin a safe but effective amount of a cosmetic cleaning agent, comprising an acid neutralized derivative of a surface-active betaine of the formula ##STR12## wherein R.sup.1 and R.sup.2 are the same or different and are alkyl radicals of 1 to 18 carbon atoms, provided that the sum of the number of carbon atoms of R.sup.1 and R.sup.2 is 9 to 18;
- R.sup.3 and R.sup.4 are the same or different and are lower alkyl or alkylol groups of 1 to 4 carbon atoms;
- x is an integer of from 2 to 4;
- y is 1;
- and z is an integer of from 1 to 4;
- and a carrier therefor.
