抵消恶臭的组合物
摘要：
抵消恶臭的组合物，包含(i)通式(I)R1R2R3R4N+X'的盐，其中R1、R2、R3、R4独立地选自C1-4烷基，或R1、R2、R3、R4可以一起构成含氮的环系，其中氮是吡啶鎓或咪唑啉鎓环的组成部分；且X'是抗衡离子，其特征在于其质子化形式具有1－6的酸度常数(pKa)；和(ii)通式R5R6C=CR7C(=O)YR8(II)的α,β-不饱和羰基化合物，其中R5、R6、R7和R8独立地选自氢和C1-10烃基残基，该残基可以是饱和的、不饱和的、芳族的、环状的、支链的或无支链的且任选地被取代，或R5、R6、R7和R8可以一起构成环系且Y是氧或单一共价键，条件是当R8是氢时，Y是共价键。该组合物可以掺入到消费中品且能够从空气中或表面上除去恶臭。

A malodour-counteracting composition comprising (i) a salt of general formula (I) €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 1 R 2 R 3 R 4 N + X - €ƒ€ƒ€ƒ€ƒ€ƒ(I) wherein R 1 ,R 2 , R 3 , R 4 are independently selected from C 1-4 alkyl, or R 1 , R 2 , R 3 , R 4 may together constitute a nitrogen-containing cyclic system in which the nitrogen is part of a pyridinium or an imidazolinium ring; and X- is a counterion characterised by its protonated form having an acidity constant (pKa) lying between 1 and 6; and (ii) an alpha, beta-unsaturated carbonyl compound of the general formula €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 5 R 6 C=CR 7 C(=O)YR 8 €ƒ€ƒ€ƒ€ƒ€ƒ(II) in which R 5 , R 6 , R 7 , R 8 and Y are selected such that; (a) R 5 , R 6 , R 7 , R 8 are independently selected from hydrogen and C 1-10 hydrocarbyl residues which may be saturated, unsaturated, aromatic, cyclic, branched or unbranched, and which are optionally substituted, and Y is a covalent bond; or (b) at least one of R 5 and R 6 is an ester group, the other and R 7 are selected as described in (a) and Y is oxygen, such that the compound is a di-ester or tri-ester. The composition may be incorporated into consumer products and is able to remove malodours from the air or from surfaces.
