Problems solved by technology

So, for example, with prior art compositions, users will not be able to rinse their upper body, or wash their hair, or shave their armpits during the degradation phase after applying said composition to their legs.
This can lead to a significant increase in the total time spent in the bath when excess hair needs to be removed

Embodiment

[0057] According to the formula given in Table 1, by making cetearyl alcohol, cetearyl alcohol polyoxyethylene (20) ether (ceteareth 20), PPG-15 stearyl ether, paraffin and VP / cetearyl alcohol A composition was prepared by emulsifying a 70°C melt of a carbene copolymer. The resulting mixture was cooled to 40°C before adding the depilatory agent, and the other ingredients were mixed in while cooling from 70°C to 40°C.

[0058] The resulting composition was applied to hyperhaired skin and prior art depilatory formulations were applied to hyperhaired skin of the same size. Table 2 lists the percentage of depilatory cream remaining on the skin after 3 minutes, 4 minutes, 5 minutes and 6 minutes of water running down the shower head. The results are also shown in graph form in the figure 1 , where the graph plots the percentage of cream that remained on the skin during the test.

[0059] The resulting composition exhibits improved low rinse properties compared to prior art depil...

Abstract

Depilatory compositions comprising a depilatory agent , fatty alcohol and VP / hexadecene copolymer provide improved resistance to rinsing of the compositions from the skin . The compositions provide f or a method - of depilation in wet conditions using a tool to apply and remove the compositions .

Description

technical field [0001] The present invention relates to a depilatory composition in the form of an oil-in-water emulsion, to the preparation of the depilatory composition, and to a method of using the depilatory composition to remove hair from human skin. Background technique [0002] Compositions for removing excess body hair are known and come in a variety of types. One type of composition requires initial heating before being applied to the skin in a generally molten state. It is then allowed to cure before being removed from the skin along with the unwanted hair. This is known in the art as epilation because the hair is removed from the skin by the root. [0003] Another type of composition is in the form of a cream, which can be applied to the skin at room temperature. The cream includes substances that degrade keratin in the hair. The composition is typically applied to the skin where unwanted hair is located and then left on the site for a predetermined period of ...
