Improvement of the foam properties of foam aerosols by addition of 1 to 35% by weight of a 1,2-propylene glycol mono-C1-C3-alkyl ether.

Description

enaüaclsU: -ZÜrtitÜ

The present invention relates to foam aerosol preparations water-based with improved foam properties, in particular hair care products; So-called foam aerosols are aerosols consisting of three phases, in particular for use in hair care products, shaving foams, skin creams, sunscreens, Etc; are suitable.

They usually contain larger amounts of water. Here is however, the need for existing, water-insoluble active ingredients in solution bring to. A certain amount of organic solvents, for example lower ones Alcohols, however, have the effect that the foaming behavior of these aerosols has a negative effect will.

It has now been found that this disadvantage can be remedied and foam aerosols with excellent foaming behavior can be obtained using such aerosol compositions on an aqueous basis as solvent 1 to 35% by weight, based on the total composition, at least one propylene glycol monoalkyl ether from the group 1-methoxy, 1-ethoxy, 1-n-propyloxy and / or 1-isopropyloxypropanol (-2) is added.

The use of these solvents in foam aerosol compositions Surprisingly not only results in no impairment of the foam properties these products, but is also suitable for active ingredients, dyes and other auxiliaries excellent to bring into solution. They are toxicologically safe and excellent skin and mucous membrane compatible, have, in contrast to other solvents, have a slight inherent odor and are, in contrast to, for example, for isopropyl alcohol, easily perfumable and often used for this purpose Finally, because of their low price, they are also economical and inexpensive applicable.

These propylene glycol alkyl ethers are in the preparations according to the invention in an amount of about 1 to about 35% by weight, preferably 2.5 to 25% by weight, in particular 5 to 15% by weight, based on the total composition.

-2- The foam aerosol composition composed of the present invention en can be used as solutions, dispersions, emulsions or suspensionsX such as pastes for Use. Emulsions whose composition is known per se are preferred and for example in the monograph by P.A. Sanders, "Principles of Aerosol Technology" (1970, Van Nostrand Reinhold Co., New York), p.

222-295.

Information on the formulation of foam aerosol preparations can be found at also at H.R. Sheperd, "Aerosols: Science and Technology" (1961, Interscience Publishers Inc., New York), pp. 313-360, and A.

Herzka / J. Pickthall, "Pressurized Packaging (Aerosols)" (1958, Butterworths Scientitic Publications, London), pp. 229-243.

Suitable products in the form of foam aerosol compositions can be packaged, are in particular hair and skin care products such as shampoos, Conditioners, hair dyes and tints; Skin creams, sunscreens, shaving aids, Depilatories, foam masks, deodorants or antiperspirants.

The raw, active ingredients used in such compositions and auxiliary materials are known and do not need to be listed here.

In addition to the propylene glycol monoalkyletheni used according to the invention can also use other solvents in the good foam properties of the invention Composition non-impairing amounts may be included; such solvents are in particular lower alcohols such as ethyl, n-propyl or isopropyl alcohol, preferably in an amount up to 10% by weight of the total composition.

Foam aerosol preparations contain propellant gases in a proportion from about 4 to about 25 percent by weight of the total composition.

Known suitable propellants are chlorofluorocarbons how Dichlorodifluoromethane, trichloromonofluoromethane, difluoroethane, dithlortetrafluoroethane, etc; and hydrocarbons such as butane, isobutane and propane and their mixtures.

Compressed gases such as nitrogen, N20 or carbon dioxide can also be used be used.
