[0060] Example Ex.1 was compared to a commercial product, known under the Product name Nivea repair and care, which has the following INCI: aqua, glycerin, C15-19 alkane, isopropyl palmitate, cetearyl alcohol, dimethicone, glyceryl stearate SE, panthenol, glyceryl stearate, myristyl alcohol, cera microcristallina, hydrogenated coco-glycerides, paraffinum liquidum, carbomer, sodium cetearyl sulfate, sodium hydroxide, ethylhexylglycerin, phenoxyethanol, linalool, benzyl alcohol, parfum.

[0061] The formulas were compared by applying 100 μl of each formula on two separate square section (size: 8 cm×5 cm) on the back, namely one on each side net to the spine, of a human body. After application (5 minutes) it was evaluated how much residue was found to be left. The rating was in the range from—meaning low amount of residue—to 5—high amount of residue. Furthermore, the absorption speed was analyzed by comparing both sections.

[0062] In this first set of experiments it was found that the score for the residue for Ex.1 was 2.0 while the commercial had a worse score with 2.3. Furthermore, it was noticed that Ex.1 absorbed significantly faster than the commercial product.

[0063] Afterwards, the participants in the study were ask to start cycling for 15 minutes. While workout the back of the participants were monitored using a thermal imaging camera. After the workout it was found that the skin surface temperature of the section treated with Ex.1 was in average 2° C. lower than the one treated with the commercial product. The barrier formed commercial product leads to a heating up of the skin which is not desirable. No barrier was formed in the section treated with Ex.1 such that heat can be released to the environment. Accordingly, without the barrier the cutaneous respiration and/or the breathability of the human skin is not hindered, while a moisturization effect of the skin is achieved. Both products were perceived by the participants to moisturize the skin sufficiently.
