Abstract

Suggested are new flavour and fragrance compositions comprising selected acetophenone derivatives for dissolving flavours and fragrances, and further especially for dissolving lipophilic compounds, which are implemented in these products.

First claim

The invention claimed is:

1. A formulation consisting of:
(a) from 0.05 to 5.0% by weight of 4-hydroxyacetophenone or a cosmetically or pharmaceutically acceptable salt thereof;
(b) from 0.05 to 5.0% by weight of at least one lipophilic flavor and/or fragrance having a different structure from said component (a);
(c) from 0.05 to 10% by weight lipophilic components;
(d) from 0.5 to 25% by weight of at least one emulsifier selected from the group consisting of
products of the addition of 2 to 30 mol ethylene oxide and/or 0 to 5 mol propylene oxide onto linear C 8 -C 22 fatty alcohols, onto C 12 -C 22 fatty acids and onto alkyl phenols containing 8 to 15 carbon atoms in the alkyl group;
C 12 -C 18 fatty acid monoesters and diesters of addition products of 1 to 30 mol ethylene oxide onto glycerol;
glycerol mono- and diesters and sorbitan mono- and diesters of saturated and unsaturated fatty acids containing 6 to 22 carbon atoms and ethylene oxide addition products thereof;
addition products of 15 to 60 mol ethylene oxide onto castor oil and/or hydrogenated castor oil;
polyol esters;
addition products of 2 to 15 mol ethylene oxide onto castor oil and/or hydrogenated castor oil;
partial esters based on linear, branched, unsaturated or saturated C 6-22 fatty acids, ricinoleic acid, or 12-hydroxystearic acid, or glycerol, polyglycerol, pentaerythritol, dipentaerythritol, or alkyl glucosides;
mono-, di and trialkyl phosphates and mono-, di- and/or tri-PEG-alkyl phosphates and salts thereof;
wool wax alcohols;
polysiloxane/polyalkyl polyether copolymers;
mixed esters of pentaerythritol, fatty acids, citric acid and fatty alcohol and/or mixed esters of C 6-22 fatty acids, methyl glucose and polyols;
polyalkylene glycols;
glycerol carbonate;
partial glycerides;
sorbitan esters;
aliphatic C 12 -C 22 fatty acids;
betaines;
N-alkyl glycines;
N-alkyl propionic acids;

N-hydroxyethyl-N-alkylamidopropyl glycines;
N-alkyl taurines;
N-alkyl sarcosines;
2-alkylaminopropionic acids; and
alkylaminoacetic acids containing around 8 to 18 carbon atoms in the alkyl group;
(e) from 5% by weight to 50% by weight alcohol;
(f) water; and
(g) a further additive selected from the group consisting of superfatting agent, consistency factor, rheology additive, polymer, silicone, wax, stabilizer, primary sun protection factor, secondary sun protection factor, anti-ageing active, cooling agent, antimicrobial agent, dye, fragrance, flavor, aroma compounds, organic solvent, sequestrant, chelating agent, and thickener, on condition that the amounts of (a)-(g) which are present in the formulation add up to 100% by weight;
wherein the formulation is selected from the group consisting of a cosmetic formulation, a pharmaceutical formulation, and a household formulation.

2. A clear transparent solution consisting of:
(a) from 0.05 to 5.0% by weight of 4-hydroxyacetophenone or a cosmetically or pharmaceutically acceptable salt thereof;
(b) from 0.05 to 5.0% by weight of at least one lipophilic flavor and/or fragrance having a different structure from said component (a);
(c) from 0.05 to 10% by weight lipophilic components;
(d) from 0.5 to 25% by weight of at least one emulsifier selected from the group consisting of
products of the addition of 2 to 30 mol ethylene oxide and/or 0 to 5 mol propylene oxide onto linear C 8 -C 22 fatty alcohols, onto C 12 -C 22 fatty acids and onto alkyl phenols containing 8 to 15 carbon atoms in the alkyl group;
C 12 -C 18 fatty acid monoesters and diesters of addition products of 1 to 30 mol ethylene oxide onto glycerol;
glycerol mono- and diesters and sorbitan mono- and diesters of saturated and unsaturated fatty acids containing 6 to 22 carbon atoms and ethylene oxide addition products thereof;

mixed esters of pentaerythritol, fatty acids, citric acid and fatty alcohol and/or mixed esters of C 6-22 fatty acids, methyl glucose and polyols;
polyalkylene glycols;
glycerol carbonate;
partial glycerides;
sorbitan esters;
aliphatic C 12 -C 22 fatty acids;
betaines;
N-alkyl glycines;
N-alkyl propionic acids;
