Abstract
There are provided wrinkle reducing compositions and method for treating fabrics in order to improve various properties of fabrics, in particular, reduction or removal of unwanted wrinkles, by means of an aqueous composition comprising a nonionic polyhydric alcohol humectant and a water-soluble wetting agent selected from a cationic surfactant, a non-alkoxylated nonionic surfactant and an anionic surfactant.
Claims37
A wrinkle reducing composition, comprising:
- (A) a wrinkle reducing active, comprising a nonionic polyhydric alcohol humectant and a water-soluble wetting agent selected from the group consisting of a cationic surfactant, a non-alkoxylated nonionic surfactant, and an anionic surfactant;
- (B) at least one material selected from the group consisting of:
- a salt having the formula:
- AM, wherein A is a cation selected from the group consisting of sodium, calcium, potassium, and magnesium, and M is an anion selected from the group consisting of sulfate, chloride, nitrate, carbonate, borate, and carboxylate;
- uncomplexed cyclodextrin;
- and
- a lubricant selected from the group consisting of a water-insoluble cationic softener, cyclomethicones, and fatty acid esters of mono- or polyhydric alcohols or anhydride thereof containing from 1 to 8 carbon atoms;
- and
- (C) a liquid aqueous carrier.
A method for reducing or removing wrinkles on fabrics and malodours on fabrics which comprises the steps of contacting the fabrics with a composition comprising
- A. a wrinkle reducing active, comprising a nonionic polyhydric alcohol humectant and a water-soluble wetting agent selected from a cationic surfactant, a non-alkoxylated nonionic surfactant and an anionic surfactant;
- B. an uncomplexed cyclodextrin;
- and
- C. a liquid aqueous carrier.
A wrinkle reducing composition, comprising:
- A. a wrinkle reducing active, comprising a nonionic polyhydric alcohol humectant and a water-soluble wetting agent selected from a cationic surfactant, a non-alkoxylated nonionic surfactant and an anionic surfactant;
- provided that when said water-soluble wetting agent is a cationic surfactant comprising a choline ester, said choline ester has the structure:
- wherein R1 is a C10-C22, preferably a C12-C14 linear or branched alkyl, alkenyl or alkaryl chain or M−, N+(R6R7R8)(CH2)s;
- X and Y, independently, are selected from the group consisting of COO, OCO, O, CO, OCOO, CONH, NHCO, OCONH and NHCOO wherein at least one of X or Y is a COO, OCO, OCOO, OCONH or NHCOO group;
- R2, R3, R4, R6, R7, and R8 are independently selected from the group consisting of alkyl, alkenyl, hydroxyalkyl and hydroxy-alkenyl groups having from 1 to 4 carbon atoms and alkaryl groups;
- and R5 is independently H or a C1-C3 alkyl group;
- wherein the values of m, n, s and t independently lie in the range of from 0 to 8, the value of b lies in the range from 0 to 20, and the values of a, u and v independently are either 0 or 1 with the proviso that at least one of u or v must be 1;
- and wherein M is a counter anion;
- and
- B. a liquid aqueous carrier.
