Abstract: front page image
(EN)The invention provides a personal care product or a home care product having self- assembled microparticles having an acid having two or more acid groups and an organic base in a solvent. The microparticles may form into a macrostructure and provide a support for carrying components of a personal care or home care composition. The particle is of micron scale. The microparticle may be obtained by contacting a bis-acid and organic base in a hydrophilic solvent, wherein the acid is insoluble or sparingly soluble in the hydrophilic solvent and the organic base is soluble in a hydrophilic solvent.
(FR)L'invention concerne un produit de soins personnels ou un produit de soins à domicile comprenant des microparticules auto-assemblées ayant un acide présentant deux groupes acides ou plus et une base organique dans un solvant. Les microparticules peuvent se former en une macrostructure et fournir un support pour porter des constituants d'une composition de soins personnels ou de soins à domicile. La taille d'une particule est de l'ordre du micron. La microparticule peut être obtenue en mettant en contact un bis-acide et une base organique dans un solvant hydrophile, ledit acide étant insoluble ou peu soluble dans le solvant hydrophile et la base organique étant soluble dans un solvant hydrophile.
