Abstract

The present invention relates to a fabric softening bar composition comprising: from about 40% to about 90% by weight of the composition of a hydrophobic fabric softening compound, from about 0.1% to about 10% of an enduring perfume composition comprising at least about 70% of enduring perfume ingredients, and optionally, but preferably, from about 5% to about 30% by weight of the composition of a non-ionic surfactant, and from about 5% to about 30% by weight of the composition, water. These compositions are low sudsing, low lathering, non-detersive fabric softening compositions which provide long lasting perfume effects.

Claims

1. Yarn or fabric comprising cotton and spandex fibres, having a perfume composition deposited on the said yarn or fabric, said perfume comprising a mixture of fragrance materials characterized by containing at least 60 wt % in total of ingredients which are fragrance materials selected from both of Categories I and II:

Category I) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log₁₀P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar silicone stationary phase) lying within the range 1050 to 1600, and

Category II) esters, ethers, nitriles, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log₁₀P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar silicone stationary phase) lying within the range 1300 to 1600.

2. A method of treating yarn or fabric comprising cotton and spandex fibres which comprises treating the yarn or fabric with a perfume comprising a mixture of fragrance materials characterized by containing at least 60 wt % in total of ingredients which are fragrance materials selected from both of Categories I and II:

Category I) hydroxylic materials which are alcohols, phenols or salicylates, with an octanol/water partition coefficient (P) whose common logarithm (log₁₀P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar silicone stationary phase) lying within the range 1050 to 1600, and

Category II) esters, ethers, nitriles, ketones or aldehydes, with an octanol/water partition coefficient (P) whose common logarithm (log₁₀P) is 2.5 or greater, and a gas chromatographic Kovats index (as determined on polydimethylsiloxane as non-polar silicone stationary phase) lying within the range 1300 to 1600.
