  • Near anhydrous consumer products comprising fragranced aminoplast capsules
    Patent number: 8242069
    Abstract: A liquid substantially non-aqueous cleaning or conditioning composition containing a surfactant or a conditioning active ingredient, a content in water which is not above 10% by weight, relative to the total weight of the composition, and a fragrance encapsulated in aminoplast type microcapsules. The compositions of the invention, in the form of fabric detergents or softeners, are particularly stable during storage and have an improved olfactive impact on fabrics.
