Abstract
Emulsifying preparation includes a surfactant consisting of an ammonium quaternary compound and a higher alcohol, such as lauryl alcohol, capryl alcohol and so on in mixture with a lower mono- or bi-hydric alcohol, such as isopropyl alcohol or ethyl alcohol or hexylene glycol. This emulsifying preparation is used to quick emulsify, in cold conditions, thermolabile substances and particularly cosmetic products, such as creams, suspensions, lotions, dyeings and so on.
Description
,,IMPROVED_EM LSIFYING_PREPA ATIgN,,
The present invention relates to preparations having an emulsifying action for forming suspensions, emulsions, creams, and in particular relates to auto- emulsifying formulations suitable to rapidly perform their own action even in cold conditions, without any heating.
It is known that for the preparation of emul¬ sions, suspensions and like, there are usually used substances having a surface-acti e effect, often working, in given cases, under an adequate heating in order to faci litate the emulsifying action of the' used surfactant. By using the surfactant alone, however, a foam generally forms particularly when a stirring is applied with a view to produce the homogeni zat i on of the mixture, and this foam is not always desired, because it can slow down the subsequent packing opera¬ tions and help an undesired oxidation of some mixture component s .
The main object of the present invention is to provide an emulsifying composition able to rapidly perform its own activity at room temperature without the need of any heating. The preparation according to the present invention comprises therefore a surfact¬ ant, generally of cationic type, in combination with an antifoa ing agent and an alcoholic solvent (C to
C6) .
Examples of surfactants employable according to the present invention comprise for instance quater¬ nary ammonium compounds, such as cety L-t r i met l-ammon-
iu chloride, dimethyL-ethyl-cetyl-ammoniurn ethylsul- fate, isobutyl-cresossiethyl-dimethyl-benzylammonium chloride, cetyLpyri diniurn chloride, cetyl-t rimethy l- a monium bromide, a LkyLi soquinolini um-bromide, alkyldi- methyLbenzy lammoni urn chloride, etc.
Examples of antifoaming agents usable according to the present invention are higher alcohols such as lauryl alcohol, oleyl alcohol, cetyl alcohol, stearyl alcohol, whereas the usable alcoholic solvents are isopropyl alcohol, ethyl alcohol, butyl alcohol and hexy lene glycol.
A typical composition of the autoemu Lsi fying preparation according to present invention comprises 34% by weight of acqueous 25% solution of cetyltrime- thylammonium chloride, 33% by weight of Lauryl alcohol dissolved in an equivalent amount by weight of isopro¬ pyl alcohol or hexylene glycol. To obtain the autoemul- sifying preparation, the high molecular weight alcohol is dissolved by gently stirring in lower alcohol, and to the thus obtained solution the quaternary ammonium salt is added when continuing the gentle stirring. The thus obtained mixture is ready to cold produce emulsions for cosmetic use and in particular cosmetic hair emulsions. The present invention will now be described more particularly, based on some embodying examples that are however not to be construed in a limiting sense .

33 kg of lauryl alcohol. Once the mixing is ended,
34 kg of a 25% solution of cety Itri methy l-ammoni urn chloride are fed, always under controlled stirring, until a homogeneous solution is obtained.

When the added components have formed a homogenous solution, 4,5 kg of the emulsifying solution prepared in Example 1 are slowly added. After the addition of the emulsifying solution is completed, stirring is continued for further 15-30 minutes until the homoge¬ neous emulsion is formed. The thus obtained product can be immed ately distπ'but- ed into the vessels for packaging.

The procedures described in Example 5 are repeated by adding 1 kg of emulsifying solution according to Example 1 to 99 kg of deminera Li zed water. Compositions having similar properties as those of Examples 2 to 6 can be obtained by using as emulsifier a product prepared according to Example 1, but substituting for hexylene glycol the same amount of isopropyl alcohol. All the preparations described in previous
Examples are obtained at room temperature, and the relevant final products can be immediately distributed into the packaging vessels, without any need of resting or degassing for the obtained emulsions. Although the present invention was described and explained by means of some preferred embodiments thereof, it will be recognized that changes and/or modifications may be made by those skilled in the art, without departing from the spirit of the invention,
