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

1. An alcoholic foamable composition comprising:

a) 52 to 99 wt. %, relative to the total quantity of the foamable composition, of an alcohol or mixture of alcohols of formula R—

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

b) 0.5 to 20 wt. %, relative to the total quantity of the foamable composition, of at least one silicone surfactant selected from the group consisting of methylphenylpolysiloxanes, cyclic silicones, bis-PEG/PPG-20/20 dimethicone, PEG/PPG-14/4 dimethicone, PEG/PPG-4/12 dimethicone, PEG/PPG-20/20 dimethicone, and PEG/PPG-20/6 dimethicone, wherein said at least one silicone surfactant is not fluorinated and the surface tension of said at least one silicone surfactant lies within the range of ±

15 dyn/cm of the surface tension of component (a);

c) 0.01 to 3 wt. %, relative to the total quantity of the foamable composition, of at least one polyalkylene glycol;

d) optionally, 0.01 to 20 wt. %, relative to the total quantity of the foamable composition, of 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;

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 the surface tension of component b) is ≧

20 to ≦

40 dyn/cm.

3. 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, and mixtures thereof.

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

5. The alcoholic foamable composition according to claim 1, wherein at least 52 to ≦

99 wt %, relative to the total quantity of the foam composition, of ethanol is contained in the foamable composition alone or as part of component a).

6. The alcoholic foamable composition according to claim 1, wherein greater than 60 wt %, relative to the total quantity of the foamable composition, of ethanol is contained in the foamable composition as component a).

7. The alcoholic foamable composition according to claim 1, wherein the at least one polyalkylene glycol is selected from polyethylene oxide homopolymers.

8. The alcoholic foamable composition according to claim 7, wherein one or more of the polyethylene oxide homopolymers are selected from the group consisting of PEG-5M, PEG-7M, PEG-14M, PEG-23M, PEG-45M, and PEG-90M.

9. The alcoholic foamable composition according to claim 1, wherein the at least one polyalkylene glycol is selected from polyethylene oxide homopolymers having a molecular weight of from 100,000 to 8,000,000.

10. The alcoholic foamable composition according to claim 1, wherein 0.01 to 10 wt %, relative to the total quantity of the foamable composition, of at least one foam stabilizer is contained in the foam as component d).

11. The alcoholic foamable composition according to claim 1, wherein component d) comprises an alkylcellulose.

12. The alcoholic foamable composition according to claim 1, comprising:

55 to 96 wt % of ethanol, 1 to 10 wt % of at least one of said silicone surfactants, 0.0 to 3 wt % of ethylcellulose polymer, and 0.05 to 2 wt % PEG polymer selected from the group consisting of PEG 7M to PEG 45M and mixtures thereof.

13. A disinfectant, comprising:

the alcoholic foamable composition according to claim 1.

14. An antiseptic for wound, skin, stools and sputum disinfection or instrument disinfection, comprising:

the alcoholic foamable composition according to claim 1.

15. A laundry and surface disinfectant, comprising:

the alcoholic foamable composition according to claim 1.

16. A skin and hand disinfectant, comprising:

the alcoholic foamable composition according to claim 1.

17. A method of disinfecting skin with a stabilized pump foam said method comprising:

applying a stabilized pump foam to the skin of a consumer, wherein stabilized pump foam is formed from the alcoholic foamable composition according to claim 1.

18. The method of claim 17, wherein the stabilized pump foam is applied to a hand of the consumer.

19. The method of claim 17, wherein component a) of the foamable composition is ethanol at a concentration of greater than 60 wt %, relative to the total quantity of the foam composition.

20. A method of dispensing a stabilized pump foam, said method comprising:

dispensing a stabilized pump foam from a pump-foam system, wherein the stabilized pump foam is formed from the alcoholic foamable composition according to claim 1.

21. A pump-foam system for dispensing a stabilized pump foam, said pump-foam system comprising:

the alcoholic foamable composition according to claim 1 to be dispensed via the pump-foam system.
