Abstract

An alcoholic foam composition, which can be dispensed as a foam via a pump-foam system contains a) at least 52 to ≦99 wt % of an alcohol or mixture of alcohols, b) a surfactant or a surfactant mixture, c) at least one polyalkylene glycol, d) optionally, at least one foam stabilizer, e) optionally, at least one member selected from the group consisting of cosmetic auxiliaries, adjuvants, active ingredients, and mixtures thereof, and f) optionally water. The surface tension of component b) lies in the range of ±15 dyn/cm of the surface tension of component a) or corresponds to the surface tension of component a), and the sum of components a) to f) is 100 wt % relative to the total quantity of the foam composition.

Claims (31)

1. An alcoholic foamable composition, capable of forming a stabilized pump foam, comprising:

a) 55 to 96 wt % of an alcohol or a mixture of alcohols of the general formula

R—OH

wherein R denotes an aliphatic straight-chain or branched hydrocarbon group having 1 to 8 carbon atoms,

b) 1 to 10 wt % of (i) at least one silicone surfactant or (ii) a mixture of fluoro and silicone surfactants, wherein the surface tension of (i) or (ii) is 20 to 40 dyn/cm,

c) 0.05 to 2 wt % PEG polymer selected from the group consisting of PEG 7M to PEG 45M and mixtures thereof,

d) 0.1 to 3 wt % of ethylcellulose polymer as foam stabilizer,

e) optionally, at least one member selected from the group consisting of cosmetic auxiliaries, adjuvants, active ingredients, and mixtures thereof, and

f) water,

wherein the sum of components a) to f) is 100 wt % relative to the total quantity of the foamable composition, and

wherein said alcoholic foamable composition is in the form of a pump-foam formulation before it is foamed, said pump-foam formulation being capable of forming a stabilized pump foam.

2. The alcoholic foamable composition according to claim 1 , wherein component a) comprises at least one member selected from the group consisting of methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, isobutyl alcohol, tert-butyl alcohol, the amyl alcohols, 1-petanol, 2-pentanol, 3-pentanol, neopentyl alcohol, 1-hexanol and mixtures thereof.

3. The alcoholic foamable composition according to claim 1 , wherein component a) is ethanol.

4. The alcoholic foamable composition according to claim 1 , wherein the surfactant consists of a silicone surfactant or a mixture of silicone surfactants.

5. The alcoholic foamable composition according to claim 1 , which does not comprise a fluoro surfactant.

6. The alcoholic foamable composition according to claim 1 , wherein component b) comprises a polysiloxane-polyether copolymer.

7. The alcoholic foamable composition according to claim 1 , wherein component b) comprises a teraalkylammonium perfluoroal kylsulfonate.

8. A disinfectant, comprising the alcoholic foamable composition according to claim 1 .

9. An antiseptic for wound, skin, stools and sputum disinfection or instrument disinfection, comprising the alcoholic foamable composition according to claim 1 .

10. A laundry and surface disinfectant, comprising the alcoholic foamable composition according to claim 1 .

11. A skin and hand disinfectant, comprising the alcoholic foamable composition according to claim 1 .

12. An alcoholic foamable composition, capable of forming a stabilized pump foam, comprising:

a) 55 to 96 wt % , relative to the total quantity of the foamable composition, of ethanol,

b) 1 to 10 wt % of bis-PEG/PPG-20/20 dimethicone which is not fluorinated,

c) 0.05 to 2 wt % PEG polymer selected from the group consisting of PEG 7M to PEG 45M and mixtures thereof,

d) 0.1 to 3 wt % of ethylcellulose polymer,

e) optionally, at least one member selected from the group consisting of cosmetic auxiliaries, adjuvants, active ingredients, and mixtures thereof, and

f) water,

wherein the surface tension of component b) lies in the range of ±15 dyn/cm of the surface tension of component a) or corresponds to the surface tension of component a), and

wherein the sum of components a) to f) is 100 wt % relative to the total quantity of the foamable composition,

wherein said alcoholic foamable composition is in the form of a pump-foam formulation before it is foamed, said pump-foam formulation being capable of forming a stabilized pump foam.
