Abstract:
1. A method for imparting a substantive fragrance and, optionally, anti-static properties to fabrics in a washing machine and/or in an automatic clothes dryer comprising tumbling said fabrics under heat at a temperature in the range of from about 40° C. up to about 100° C. in said washing machine and/or in said dryer with (a) at least one three-dimensional sachet article which evolves, during the washing cycle and/or during at least one drying cycle, an effective amount of a fragrance-imparting composition at an effective rate and, optionally, an effective amount of an anti-static property-imparting composition at an effective rate and, optionally, (b) an effective amount of an anti-static property-imparting composition separate from said sachet article, said three-dimensional sachet article comprising: i. a non-rigid or substantially rigid hollow containment means consisting of a non-rigid or substantially rigid container wall which is a perforated or continuous, thin lamina separating an inner void from an outer environment totally surrounding said inner void; having a height of from about 4 up to about 10 cm. and a width of from about 1 up to about 10 cm and which is permeable to fragrance compositions and anti-static property-imparting compositions, each of the fragrance components of which fragrance compositions has a calculated C log ii. contained within a major proportion of said inner void and supported by said non-rigid or substantially rigid perforated or continuous container wall, a plurality of polymeric fragrance composition and, optionally, anti-static property-imparting composition-containing and evolving solid or visco-elastic particles which have a total weight of from about 2 grams up to about 50 grams, each of which has an average effective diameter of from about 0.5 mm up to about 10 mm, said fragrance composition, and a filler selected from the group consisting of CaCO wherein C log 10 P is the calculated logarithm to the base 10 of the n-octanol/water partition coefficient for each of the fragrance components of said fragrance composition.
