Benefits of technology

[0008] The use of articles of this type makes it possible to lift the constraints of formulation in so far as these articles can produce a large range of products, from gels to creams, for various applications, according to the composition applied to the support.

Problems solved by technology

However, insoluble-support patches have the drawback, firstly, of generating waste to be eliminated and, secondly, of being able to perform only one function and of not being modulatable according to the desired aim, contributing to an increase in the number of products to be used in routine care.
However, these films have the drawback of being complex to manufacture, with solubilization of the components, heating and drying in order to obtain a dry film.
In addition, they are difficult to dry if they are too thick, and they are fragile and difficult to handle if the size is too great.

examples

[0117] The article used in the examples is prepared with a support made of PVA-based Kuralon K-II WN2 fibres. It is obtained by heat-sealing, at their periphery, two layers having a weight of 80 g / m2. The article is in the form of a disc 3 cm in diameter, comprising a cavity into which is introduced the composition in an amount of approximately 0.3 grams.
