Cosmetic use as deodorant active agent of a siliceous material obtained by hydrolysis and condensation of a tetraalkoxysilane and of an aminoalkyl trialkoxysilane

Abstract

The invention thus relates to the cosmetic use of a siliceous material that may be obtained by hydrolysis and condensation, in the presence of water, of at least one tetraalkoxysilane of formula (I) below: Si(OR)(I) and of at least one aminoalkyl-trialkoxysilane of formula (II) below: RSi(OR)(II) Rdenotes a linear or branched C-Calkyl group; Rdenotes a linear or branched, saturated or unsaturated C-Chydrocarbon-based group, a cyclic C-Chydro-carbon-based group, or denotes a C-Caryl or C-Caryloxy group; the said radicals being substituted with an amino group NHor NHR with R denoting a linear or branched C-Calkyl group; Rdenotes a linear or branched C-Calkyl group; the said material being other than a molecularly imprinted polymer. The invention also relates to a cosmetic process for treating human body odor, in particular underarm odor and optionally human perspiration, which consists in applying to human keratin materials the said siliceous material or a composition containing the same in a cosmetically acceptable medium. The invention also relates to a composition characterized in that it comprises, in a cosmetically acceptable medium, at least the said siliceous material and at least one deodorant agent other than the said siliceous material and/or at least one antiperspirant active agent.
