This holds also true for make-up, which shall be removed from the skin, hair and skin appendages, and in particular from the face.
Cleansing compositions intended for face cleansing have to meet special requirements. As the skin of the face is a very sensitive part of the skin, the eye area and the eyes being even more sensitive, cleansing compositions for face cleansing have to be compatible to the skin of the face and the eyes. Furthermore, the compositions have to be distributed on the skin easily, without the necessity of intense rubbing, which may lead to skin irritations.
To meet these requirements a cleansing composition in form of a foam may be provided.
Prior art already knows cleansing compositions in form of a foam.

There is still the need to further improve the cleansing compositions in form of foam cleanser. It is desirable to provide a transparent composition, which upon release from the packaging device generates a stable foam. The foam should be sufficiently stable. Moreover, the com position has to be transparent even at lower temperatures, which might occur during trans portation in winter. Additionally, in order to remove make-up, too, the cleansing foam has to show a high cleansing efficacy.

Examples
The examples below are intended to illustrate the present invention without limiting it. The numerical values in the examples are percentages by weight, based on the total weight of the particular preparations, given as active content.
Example 1 :
Example 2:
Example 3:
Example 4:
Example 5:
In order to evaluate the influence of fatty acids and/or the respective salts thereof having dif ferent chain length on the long term stability, different compositions were produced.
Neutralisation Rate 103%
Sample preparation:
1 ) Weigh in all the raw materials for each sample into a beaker,
2) Heat under stirring to 70°C until clear solution,
3) Cool down to room temperature.
Samples of the different compositions were kept at different temperatures and photos were taken. The results are shown in Figures 1 to 3.
*room temperature
The above mentioned tests were conducted because the solubility of fatty acids decreases with decreasing temperature. Decreasing temperature is an issue, if the products are trans ported and stored at temperatures, which are typical in winter. At lower temperatures the fatty acids tend to precipitate. These precipitates might clog the pump header of the packag ing device. This clogging might then result in a bad foam quality, especially an irregular foam
The transparency of a sample at lower temperatures indicates that no precipitates are formed and in consequence the foam quality will be as desired, namely a regular, stable foam, even at lower temperatures.
Referring to stability at lower temperatures the compositions 1 and 2 show the best results. Compositions 1 and 2 contain the fatty acid with the higher number of carbon atoms, namely palmitic acid, in a lower amount than the fatty acids having smaller numbers of carbon at oms, namely lauric acid and myristic acid. It becomes apparent that it is important to pay at tention to the composition of the combination of fatty acids. Best results are obtained, if fatty acids having smaller numbers of carbon atoms are contained in excess to the fatty acid hav ing a higher number of carbon atoms.
To evaluate the foam stability the above mentioned compositions 1 to 6 were filled in a pack aging device, namely a pump foamer. An equal amount of foam was released directly to a tissue paper. The paper was monitored with regard to the water liberated from the foam. The higher the amount of water liberated from the foam the less stable the foam is. After 20 minutes of monitoring it became apparent that the foam of compositions 1 , 2, and 3 showed a higher stability than the foam of compositions 4, 5, and 6.
Furthermore, the stability of the foam was evaluated after having been distributed on the skin, in this case on the hands. Compositions 1 to 6 were filled in a packaging device, namely a pump foamer. An equal amount of foam was released directly to one hand. The foam was distributed by rubbing for 20times. The results are shown in Fig. 4.
It becomes apparent that after rubbing the foam of compositions 1 to 3 is more prominent, indicating a more stable foam.
In addition, the creaminess of the foam and the feeling of the skin were evaluated in a panel test. 8 persons applied the foam, generated from compositions 1 to 6 to their hands. The creaminess of the foam was evaluated as well as the smoothness of the skin after rinsing off the foam on a scale of 5, where 1 means bad and 5 means very good.
It becomes apparent, that the creaminess of the foam of compositions 1 to 3 was evaluated better than the creaminess of the foam of compositions 4 to 6.
Summing up, all 6 compositions generate stable foams, however compositions having a total amount of fatty higher than 1 % by weight are evaluated better.
Example 6:
In a second step the influence of certain polyols was evaluated in relation to foam properties and quality. For this purpose different compositions were prepared.
The composition of the combination of fatty acids was kept unchanged.
Sample preparation:
1 ) Weigh in all the raw materials for each sample into a beaker,
2) Heat under stirring to 70°C until clear solution,
3) Cool down to room temperature.
To evaluate the foam stability the above mentioned compositions 7 to 1 1 were filled in a packaging device, namely a pump foamer. An equal amount of foam was released directly to a tissue paper. The paper was monitored with regard to the water liberated from the foam. The higher the amount of water liberated from the foam the less stable the foam is. After 1 hour of monitoring it became apparent that the foam of composition 8 showed the lowest sta bility, the foam was collapsed nearly completely. Compositions 7, 9, 10, and 1 1 showed a significantly higher foam stability.
Furthermore, the stability of the foam was evaluated after having been distributed on the skin, in this case on the hands. Compositions 7 to 1 1 were filled in a packaging device, namely a pump foamer. An equal amount of foam was released directly to one hand. The foam was distributed by rubbing for 20times. The results are shown in Fig.5.
It becomes apparent that after rubbing the foam of composition 8 disappears more quickly than the foam of the other compositions. The foam generated from composition 8 is less sta ble.
In addition the creaminess of the foam and the feeling of the skin were evaluated in a panel test. 8 persons applied the foam, generated from compositions 7 to 1 1 to the hands. The creaminess of the foam was evaluated as well as the smoothness of the skin after rinsing off the foam on a scale of 5, where 1 means bad and 5 means very good.
It becomes apparent that overall the creaminess of the foam of compositions 7 to 1 1 was evaluated better than the creaminess of the foam of compositions 1 to 6, shown in Example 5. The same holds true for the feeling of the skin after rinsing. The compositions 1 to 6 ac cording to example 5 do not contain any polyol. The addition of polyols, however, contributes to the stability of the foam, helps to improve the creaminess of the foam and results in a bet ter feeling of the skin after having rinsed off the foam. Having a more detailed look at the re-
suits, the foam generated from compositions 9 to 1 1 is evaluated better than the one of com position 7 and 8. Compositions 9 to 1 1 contain mixtures of polyols, namely mixtures of glyc erol and propylene glycol.
Furthermore, the skin feeling after rinsing off the foam is evaluated better after application of foam generated from compositions 9 to 1 1 than the skin feeling after application of foam from compositions 7 and 8. Also in relation to the skin feeling, a mixture of polyols, in this case glycerol and propylene glycol, results in the best evaluations.
