Title (EN) HAIR TREATMENT COMPOSITIONS COMPRISING PARTICULATE SUBSTANCES
(FR) COMPOSITIONS DE TRAITEMENT CAPILLAIRE CONTENANT DES SUBSTANCES PARTICULAIRES
Abstract: front page image
(EN)A hair treatment composition which comprises 0.01-5.0 wt% of a particulate substance which is substantially unagglomerated or unaggregated prior to incorporation in the composition, which particulate substance has a modal primary particle size of 7-40 nm, and a Young modulus of at least 4 Gpa, preferably at least 6 GPa, wherein the particulate substance is a silica, a cross-linked polymer, an alumina, an alumina silicate, or a colloidal metal such as titanium dioxide. The association between the primary particles in the composition is such that at least 75 % of the particles are in the form of monodisperse primary particles or have an associated particle size of less than 100 nm.
(FR)La présente invention concerne une composition de traitement capillaire contenant entre 0,01 et 5,0 % en poids d'une substance particulaire qui est sensiblement non agglomérée ou non agrégée avant d'être incorporée dans la composition, cette substance particulaire présentant une taille de particule primaire modale comprise entre 7 et 40 nm, et un module de Young d'au moins 4 GPa, de préférence au moins 6 GPa. Cette substance particulaire peut être de la silice, un polymère réticulé, de l'alumine, du silicate d'alumine, ou un métal colloïdal tel que le dioxyde de titane. L'association entre les particules primaires dans la composition est telle qu'au moins 75 % des particules se présentent sous forme de particules primaires mono-dispersées ou sont caractérisées par une taille de particule associée de 100 nm minimum.
