cleaning agents having a pearl luster effect. In these ~ethods, so-called pearl luster dispersions~ based on various pearlescent substances, are used in combination with surfactants, the pearl luster effect being obtained by incorp~rating the pearlescent substan~e in high concen-tration and at above the melting point into the surfactant which is likewise present in high concentration. The precise cooling and stirring conditions under which the incorporation is carried out bring about the formation of pearl luster crystals having a defined particle size distribution.
The substances ~hich are used at present for pre-paring these pearl luster dispersions are fatty acid monoglycol and/or polyglycol esters ~hich are incorporated alone or combined ~ith alkanolamides in anionic surfactants, such as, for example, alkyl sulfates or polyoxialkylene alkyl sulfates talkyl ether sulfates), as solvents or dispersants. The result is usually that the dispersions obtained are very viscous and no longer fluent at lower temperatures~
Owing to the high alkyl sulfate or alkyl ether sulfate content~ these pearl luster dispersions have the following disadvantages:
incompatibility with cationic surfactants in cationic formulations, such as hair conditioners and fabric softeners, the present pearl luster concentrates form neutral salts which are in some cases insoluble, thereby ~eakening the cationic charge and thus reducing ~he desired effect; sensitivity of the alkyl sulfates or alkyL ether sulfa~es ~o hydrolysis~ especially at lo~ pH
(~ pH 5); pronounced foaming in processing, o~ing to the presence of large a~ounts of surfactants having pro-nounsed foaming properties; hi~h viscosity at low temperatures and hence difficult handling in transport and processing;
formulations free of alkyl sulfate or alkyl ether sulfate impossible; and presence of toxicologically unsafe dioxane on using pearL luster concentrates containing alkyl ether sulfate.

~e) substantial reduction of the dioxane content.
~ here no~ follo~s a description of the components required for preparing pearl luster dispersions of the invention having opt~nal application properties and of the concentrations in ~hich the components are employed therein~
Suitable pearlescent substances are the fa~y ~cid glycol esters of the formula tI) and mixtures of this class of substance~ The most favorable properties ar~ shown by compounds in ~h~ch R1 is an alkyl radic~l of 1S-17 carbon atoms, m ;s 1 and X is a rad;cal of the :
~ ,-- ~23~2~2 formula R1-C0~. These componen~s are preferably used in a concentration of 10-20% by weight, the optimal con-centration having been found to be 16%.
Preferred fatty acid alkanolamides of the formula 5 (II) have a distribution of 10-18 carbon atoms in the parent fatty acid. Of these, preference ;s given to fatty acid ~onoethanolamides in which one of the t~o radicals R3 or R4 in the formula (II) represents a hydrogen atom and the other radical represents a group of the ~ormula -C2H40H.
This component is preferably used in a concentra ~ion of 2-10X, in particular 4X.
It has been found that, of the suitable nonionic surfactan~s of the formula III, compounds in ~hich R5 rePresents an alkyl group of 10 18 carbon atoms, ~hich may be linear or branched, and m and n each represent 4 are especially advantageous. This nonionic component is preferably used in a concentration of O.S - 5X, in ~ar-ticular 2%. The water used in the present in~ention is demineralized water.
The procedure for preparing the pearl luster dis-persion according to the ir~vention is as follo~s. A ~ixing vessel (heatable boiler) is charged with the t~o components of the formulae I and II, and the mixture is then heated to about 76C, turning into a ~elt. This ~elt has added to it ~ith stirring a hot aqueous solution of the component of the for~ula III likewise at 75C. The speed of stirring should not be excessively high and should be about between 10 and 100 revolutions per minute. The resulting dispersion is stirred at a temperature of 75C
for approximately a further 3D ninutes. The dispersion is then cooled do~n ~ith stirring to an end temperature of 20~30C. The rate of cooling should take place under controlLed conditions, na~ely in the same way as is the practice with hitherto customary pearl luster dispersions to obtain a constant, reproducible pe~rl lus~er effect.
In the course of cooling, the two components I
and I~ start to crystallize at about 50-60C and form the desired pearl luster.
~l~3~ ;;2 In addition to the abovementioned main components, the pearl luster dispersion according to the invention can also contain additives such as preservatives, buffer substances and electrolytes. The pH of the dispersisn is within the ran~e from 4 to 9, preferably from 5 to 8.
The present pearl luster dispersion a~cording to the invention can be added to such hair-cleaning and body~cleaning agents, dish~ashing agents, detergents and cleaners as are liquid at room temperature. The results are end products ~hich exhibit a remarkable pearl luster.
The amount of pearl Luster dispersion ~eeded to ensure the desired effect is generally bet~een 1 and 10Xa Since the pearl luster dispersion according to ~he invention has a comparatively lo~ viscosity at tem-peratures above 10C~ it is possible ~o process the dispersion by means of automatic pumping, metering and mixing machinery. That is of particular interest in the fully con~inuous production o~ finished products having a pearl luster effect.
Pearl luster dispersions according to the inven-tion are described in the following examples. The indicated quantities are in each case percentages by weigh~. "EO" means ethylene oxide and "PO" propylene oxide.

These pearl luster disPersions specified in Examples 1-5 were tested from the foLlowing aspects:
; 1~ assessment of the pearl luster effect 2. determination of the optical density 3. viscosity or flow behavior 4. shelf life at temperatures higher and lo~er than room temperature.
The test ~ethods used were those customary in thè cosmetic industry. The pearL luster effect ~as assessed visually in comparison to commercially available pearl luster dispersions. The optical density ~as determ1ned photometrically on 0.5 g/l dilutions in water by means of a Dr. Large turbidimeter.
Tested from these aspects the pearl luster dis-persions described in Examples 1-5 have excellent properties ~hich are comparable to those of commercially available products orD in some cases, are better than those of com-mercially available products~ Ho~ever~ unlike these com~ercially ~vailable dispersions, the dispersions according to the invention are fluent even below 20C.

The speed of stirring should not be excessively high and should be about between 10 and 100 revolutions per minute. The resulting dispersion is stirred at a temperature of 75C
for approximately a further 3D ninutes. The dispersion is then cooled do~n ~ith stirring to an end temperature of 20~30C. The rate of cooling should take place under controlLed conditions, na~ely in the same way as is the practice with hitherto customary pearl luster dispersions to obtain a constant, reproducible pe~rl lus~er effect.
In the course of cooling, the two components I
and I~ start to crystallize at about 50-60C and form the desired pearl luster.
~l~3~ ;;2 In addition to the abovementioned main components, the pearl luster dispersion according to the invention can also contain additives such as preservatives, buffer substances and electrolytes. The pH of the dispersisn is within the ran~e from 4 to 9, preferably from 5 to 8.
The present pearl luster dispersion a~cording to the invention can be added to such hair-cleaning and body~cleaning agents, dish~ashing agents, detergents and cleaners as are liquid at room temperature. The results are end products ~hich exhibit a remarkable pearl luster.
The amount of pearl Luster dispersion ~eeded to ensure the desired effect is generally bet~een 1 and 10Xa Since the pearl luster dispersion according to ~he invention has a comparatively lo~ viscosity at tem-peratures above 10C~ it is possible ~o process the dispersion by means of automatic pumping, metering and mixing machinery. That is of particular interest in the fully con~inuous production o~ finished products having a pearl luster effect.
Pearl luster dispersions according to the inven-tion are described in the following examples. The indicated quantities are in each case percentages by weigh~. "EO" means ethylene oxide and "PO" propylene oxide.
Example 1 Co~position Monoethylene glycol distearate 16rO%
Cocomonoethanolamide 4.0X
C10/1z~fatty alcohol ~ 4 E0 + 4 P0 2.0%
Water~ preservativeto 100.0X
Example 2 :

These pearl luster disPersions specified in Examples 1-5 were tested from the foLlowing aspects:
; 1~ assessment of the pearl luster effect 2. determination of the optical density 3. viscosity or flow behavior 4. shelf life at temperatures higher and lo~er than room temperature.
The test ~ethods used were those customary in thè cosmetic industry. The pearL luster effect ~as assessed visually in comparison to commercially available pearl luster dispersions. The optical density ~as determ1ned photometrically on 0.5 g/l dilutions in water by means of a Dr. Large turbidimeter.
Tested from these aspects the pearl luster dis-persions described in Examples 1-5 have excellent properties ~hich are comparable to those of commercially available products orD in some cases, are better than those of com-mercially available products~ Ho~ever~ unlike these com~ercially ~vailable dispersions, the dispersions according to the invention are fluent even below 20C.
