- Deposit spreading 2 cm wide and 100 ⁇ m thick on a glass plate. The deposit is made using a film puller and is left to dry for 2h and 24h.
- Friction resistance the film is scraped by a round trip with a spatula.
- % ai * percentage by weight of phyllosilicatesynthetic active ingredient in water
- compositions 1 and 2 in gel form, are stable and make it possible to obtain a film of good quality, a dry feel and to provide good resistance to water and friction. These compositions retain a sensory pleasure adapted for an antiperspirant / deodorant application.
- a synthetic phyllosilicate suitable for the invention makes it possible to have better resistance properties of the film to water and to friction, and better drying times than a formula containing synthetic phyllosilicate alone and even more. much better properties than a formula without phyllosilicate and without film-forming.
- Example 10 Other compositions according to the invention based on deodorant active agents such as zinc pidolate, Na- (1-oxododecil) -L-ethyl arginate hydrochloride or potassium alum, as electrolyte
- deodorant active agents such as zinc pidolate, Na- (1-oxododecil) -L-ethyl arginate hydrochloride or potassium alum, as electrolyte
- Examples 10.1 to 10.4 were prepared by simply mixing the ingredients with magnetic stirring at room temperature (20-30 ° C) until a homogeneous mixture was formed.
- compositions 10.1 and 10.4 according to the invention are stable after 24 hours. It has also been observed that a synthetic phyllosilicate according to the invention is not destructured by the addition of electrolytes corresponding to deodorant active agents such as zinc pidolate, N- (1-oxododecil) -L-ethyl hydroxychloride. arginate or potassium alum, and even helps to increase the viscosity of compositions comprising such electrolytes.
