Embodiment Construction

[0079] Comparative experiment (washing test) and embodiment

[0080] The effectiveness of the invention can be demonstrated exemplarily by means of the following comparative experiments: Preparation of different emulsifier systems. Furthermore, a system containing 0.8% of the adjuvant polyglyceryl-10 stearate according to the invention was compared with a formulation without the adjuvant according to the invention in order to determine by the method described a reduction in the staining effect (reduction of b* ).

[0081] As evidence of the improved elution and reduced stain formation of the formulations according to the invention, in vitro experiments were carried out, the results of which are shown in Table 1.

[0082] Various sunscreen lotions were studied for macular formation in one ex vivo application cycle / wash cycle. In this case, a white prewashed cotton monitor swatch (100% cotton) was used. To this end, each 25 mg test formulation was evenly distributed to the PM...
