Abstract

Cosmetic and/or pharmaceutical preparations comprising (a) a carbonate of the formula (I): wherein R 1 is a linear alkyl and/or alkenyl group having from 6 to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or a group derived from a polyol having from 2 to 15 carbon atoms and at least two hydroxyl groups; R 2 has the same meaning as R 1 or is an alkyl group having from 1 to 5 carbon atoms and each of n and m independently has a value of from 0 to 100; and (b) a propellant can be used as aerosols.

Claims (11)

1. A cosmetic and/or pharmaceutical preparation comprising (a) a carbonate of the formula (I):

wherein R 1 is a linear alkyl and/or alkenyl group having from 6 to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or a group derived from a polyol having from 2 to 15 carbon atoms and at least two hydroxyl groups; R 2 has the same meaning as R 1 or is an alkyl group having from 1 to 5 carbon atoms and each of n and m independently has a value of from 0 to 100; and (b) a propellant.

2. The preparation of claim 1 wherein the carbonate comprises at least one of diisooctyl carbonate, dihexyl carbonate and di-n-octyl carbonate.

3. The preparation of claim 2 wherein the dialkyl carbonate comprises di-n-octyl carbonate.

4. The preparation of claim 1 wherein the amount of the carbonate is from 1 to 50% by weight.

5. The preparation of claim 1 wherein the propellant comprises at least one member selected from the group consisting of dimethyl ether, carbon dioxide, a chlorofluorocarbons, a nitrogen oxide, pentane, butane, propane and isomers of pentane, butane and propane.

6. The preparation of claim 5 wherein the amount of the propellant is from 3 to 95% by weight.

7. The preparation of claim 1 further comprising at least one member selected from the group consisting of polymers, silicone compounds, lecithin, phospholipids, biogenic agents, UV protection factors, antioxidants deodorants, antiperspirants, antidandruff agents, film formers, insect repellents, self-tanning agents, tyrosine inhibitors, hydrotropes, solubilizers, preservatives, perfume oils, and dyes.

8. The preparation of claim 1 wherein the mole ratio of component (a) to (b) is from 1:5 to 1:1.

9. A cosmetic and/or pharmaceutical preparation comprising (a) from 1 to 50% by weight of a carbonate of the formula (I):

wherein R 1 is a linear alkyl and/or alkenyl group having from 6 to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or a group derived from a polyol having from 2 to 15 carbon atoms and at (east two hydroxyl groups; R 2 has the same meaning as R 1 or is an alkyl group having from 1 to 5 carbon atoms and each of n and m independently has a value of from 0 to 100; (b) from 3 to 95% by weight of a propellant; and (c) from 0 to 30% by weight of auxiliaries and additives and the remainder water.
