   de 0.05 à 0.2 mg/cm<2> sur la peau.

[0005] Ladite composition, qui contient de l'alcool isopropylique, qui constitue l'agent alcoolique pour la formation du film susdit, des acides organiques, dont la propriété est de former un ester en réaction avec le propylène glycol, comprend avantageusement, en poids, de 40 à 70% d'eau déminéralisée, de 10 à 45% de propylène glycol, de 0.5 à 5% d'acide malique, de 0.1 à 5% d'acide benzoïque, de 0,04 à 5% d'acide salicylique, et de 0.1 à 2.5% d'un agent conservateur, tel que le mélange 30% de parabène de propyle et 70% de parabène de méthyle connu sous le nom de "meproesters".
La composition susdite peut également comprendre un colorant améliorant son aspect, ce colorant, introduit dans la composition à raison de 0.001% à 0.01% en poids,

   étant choisi parmi les colorants neutres par rapport aux constituants susdits.

[0006] On a obtenu d'excellents résultats réparateurs de l'épiderme, et en particulier des résultats durables, avec une composition comprenant en poids 52.03% d'eau déminéralisée, 34.65% de propylène glycol associé à 1.23% de propylène glycol monomalate, de 7.5% d'alcool isopropylique, de 1.3% d'acide malique, 0.15% d'acide benzoïque, 0.04% d'acide salicilique, et de 3% d'amplificateur de l'effet filmogène.
Suivant l'invention, la composition réparatrice pour l'épiderme après brûlure, peut se présenter sous la forme d'un gel pouvant être utilisé dans un distributeur à tête de distribution (flacon-pompe).

[0007] Lorsque ce gel est destiné à être utilisé dans un distributeur à tête de distribution à bille (roll-on),

   on abaisse la viscosité du gel défini ci-dessus en augmentant la quantité d'eau.
