The following is a disclosure of two classes of skin care cosmetic compositions with excellent cosmetic properties.

The first class of compositions disclosed herein are Self Tanning Moisturising Cream/Lotions with UV-protection. These compositions have excellent application feel, skin moisturization and beauty benefits. They provide excellent skin protection against UV and free radicals as well as natural-looking tan.

The second class of compositions disclosed herein are Self Tanning Non UV - Night Moisturising Cream/Lotions. They provide the same benefits as the first type, except for a lesser degree of UV protection.

It is obvious for the skilled cosmetic formulators that the content of active ingredients in the compositions exemplified below may be modified upwards or downwards when different effects are desired. For example, if a more powerful self-tanning effect is desired, the formulator would immediately consider without any inventive activity increasing the levels of DHA. The range indicated is indicative of what would normally be considered as suitable, but the skilled person could work above or under many of these values without inventive activity.

It is also obvious for the skilled in art that all the specific ingredients listed can be replaced by their known functional equivalents. For example Simulgel® NS can be replaced by any other suitable thickener stable at low pH (<5) such as Sepigel® 305 (SEPPIC), Aristoflex® HMB (Clariant) or Viscolam AT 100 P (Lamberti) or any other suitable AMPS polymers or copolymers known to the skilled persons. The same substitution principle applies to the sunscreens and all the other ingredients listed. The CTFA books and internet websites provide a list of the common cosmetic ingredients and their functional equivalents.

Of course, further known cosmetic ingredients can be added to any of the formulations disclosed below without any inventive activity. Any of the common ingredients listed in the CTFA would be considered by the person skilled in the art for addition to the disclosed compositions to achieve any of the functionalities for which the ingredient is known.

For example, any ingredients listed in EP1,481,664A1, incorporated herein by reference, may be used in the examples below.
