CA 2192801

The present invention relates to a dryer-added fabric treatment article of manufacturing to reduce the fading of fabrics from sunlight comprising: I) a composition comprising: a) from about 5 % to about 75 %, by weight of the composition, of a sun-fade protection active selected from the group consisting of: (i) a non-fabric staining, light stable, antioxidant compound preferably containing at least one C8-C22 hydrocarbon fatty organic moiety; (ii) a non-fabric staining, light stable, sunscreen compound; and (iii) mixtures thereof; b) from about 10 % to about 95 % by weight of the composition of a fabric conditioning compound; and II) a substrate, on which said composition is attached, which provides for release of an effective amount of said sun-fade protection active and said fabric conditioning compound onto fabrics in an automatic laundry dryer at automatic laundry dryer operating temperatures; wherein said antioxidant compound is a solid having a melting point of less than about 80 ~C, or a liquid at a temperature of less than about 40 ~C; and wherein said sunscreen compound absorbs light at a wavelength of from about 290 nm to about 450 nm and is a solid compound having a melting point of from about 25 ~C to about 90 ~C, or a viscous liquid at a temperature of less than about 40 ~C.

L'invention porte sur un produit protecteur ajouté en séchoir réduisant la décoloration du linge sous l'effet de la lumière solaire et comprenant: I) une composition comprenant A) environ 5 à environ 75 % en poids d'un composé actif de protection solaire choisi dans un groupe comprenant: i) un composé antioxydant stable à la lumière et ne tachant pas le linge, contenant de préférence au moins une fraction organique grasse hydrocarbonée C¿8?-C¿22?; ii) un composé écran solaire stable à la lumière et ne tachant pas le linge; iii) un mélange des composés i) et ii); (B) environ 10 à environ 95 % en poids d'un composé de conditionnement du linge; et II) un substrat auquel est fixée ladite composition libérant une quantité efficace des composés (A) et (B) sur le linge dans les séchoirs des laveries automatiques à leur température normale de fonctionnement; le composé oxydant susdit étant soit un solide dont la température de fusion est inférieure à environ 80 ~C soit un liquide à une température inférieure à environ 40 ~C, et l'écran solaire qui absorbe la lumière pour les longueurs d'onde comprises entre environ 290 nm et environ 450 nm est un composé solide dont la température de fusion est comprise entre environ 25 et environ 90 ~C ou un liquide visqueux à une température inférieure à 40 ~C.
