Patent ID: 8496994

Claim:
A method for providing fragrance to a substrate, comprising the steps of: a) treating the substrate with a fragrance-containing composition; and b) treating the substrate with a fixative compound or mixture of fixative compounds selected from the group consisting of: a fructan; and a hydrophobically modified fructan, having the formula (I) S AC (-M) s (I) wherein SAC represents: an inulin moiety with a degree of polymerisation (DP) ranging from 2 to 100; (-M) represents a hydrophobic moiety, substituting at least one hydrogen atom of a hydroxyl group of S AC , whereby (-M) is selected from the group consisting of: an alkylcarbamoyl radical of formula R 1 —NH—CO—, an alkenyl-carbamoyl radical of formula R 2 NH—CO—, an alkylcarbonyl radical of formula R 1 —CO—, an alkenylcarbonyl radical of formula R 2 —CO—, an alkyl radical of formula R 1 —, an alkenyl radical of formula R 2 —, and a hydroxyalkyl radical of formula R 3 —, wherein: R 1 represents a linear or branched alkyl group with 4 to 22 carbon atoms, R 2 represents a linear or branched alkenyl group with 4 to 22 carbon atoms, and R 3 represents a linear branched hydroxyalkyl group with 4 to 22 carbon atoms of formula —CHR′—CHOH—R″, wherein R′ is hydrogen or a linear or branched alkyl radical and R″ is a linear or branched alkyl radical; and s represents the number of hydrophobic moieties (-M) attached to S AC , expressed as the number average degree of substitution (av.DS) per monomeric unit contained in S AC and which ranges from 0.01 to 1.0: whereby step b) may be executed prior to, simultaneously with, and/or subsequent to the execution of step a), and wherein when the substrate is a textile, steps a) and b) are carried out during a washing cycle.
