(FR) FORMULATIONS COSMÉTIQUES COMPRENANT DE L'ÉTHYLCELLULOSE
Abstract:
(EN) Ethylcellulose dispersions in water are film forming compositions that have found use in personal care applications. Conventional methods can require that aqueous dispersions of water-insoluble polymers such as ethylcellulose be obtained using surfactants such as sodium lauryl sulfate (SLS). There is a desire to reduce the degree of consumer exposure to SLS in personal care products. The present invention describes ethylcellulose dispersions comprising surfactants to substantially replace sodium lauryl sulfate. The present invention also describes methods of reducing or substantially eliminating SLS in personal care products that comprise ethylcellulose dispersions.
(FR) Les dispersions d'éthylcellulose dans l'eau sont des compositions filmogènes qui sont utilisées dans des applications de soins corporels. Les procédés classiques peuvent nécessiter que les dispersions aqueuses de polymères insolubles dans l'eau tels que l'éthylcellulose soient obtenues en utilisant des tensioactifs tels que le laurylsulfate de sodium (SLS). Il apparaît souhaitable de réduire le degré d'exposition du consommateur au SLS dans des produits de soins corporels. La présente invention concerne des dispersions d'éthylcellulose comprenant des tensioactifs visant à remplacer de façon substantielle le laurylsulfate de sodium. La présente invention concerne également des procédés permettant de diminuer ou d'éliminer substantiellement le SLS dans les produits de soins corporels qui comprennent des dispersions d'éthylcellulose.
