DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a concentrate comprising a mixture of alkylglycosides and at least one fatty alcohol, as well as to uses of these concentrates, in particular as pearling agent or for preparing emulsions.
BACKGROUND OF THE INVENTION
Alkylglycosides are well-known compounds.
They may be prepared in particular according to the processes described in French Patent Application 93.02877 filed on Mar. 12, 1993 and French Patent Application 93.03188 filed on Mar. 19, 1993, both in the name of the Applicant.
They may be used as surfactants, alone or in combination with other surfactants, in numerous applications. In this regard, reference may be made, for example, to the brochure Triton CG 110 of May 1975, distributed by the company Rohm & Haas or to patent application EP-A-70,074, which describe compositions and formulations combining surfactants and alkylglycosides, these being useful in particular in detergency or in cosmetics.
The application for patent WO 92/06778, in the name of the Applicant, describes compositions comprising 60 to 90% by weight of at least one fatty alcohol having from 12 to 22 carbon atoms and from 10 to 40% by weight of an alkylpolyoside (or alkylglycoside), the alkyl part of which may be identical to that of the fatty alcohol.
These compositions are useful as self-emulsifiable agents.
SUMMARY OF THE INVENTION
A first subject of the present invention consists of a composition in the form of an alkylglycoside-based concentrate having properties which, as far as the Applicant is aware, have never been obtained or achieved beforehand using alkylglycosides.
A second subject of the present invention consists of the use of the said concentrate as a pearling agent, for the purpose of producing a pearlescent appearance which is stable over time.
A third subject of the present invention consists of the use of the said concentrate for the preparation of emulsion, in particular of fluid emulsions such as milks, which are stable over time.
A fourth subject of in the invention consists of compositions, in particular cleansing soaps or syndets, containing the concentrate, which is of little or no irritance to man or animals.
A fifth subject of the invention consists of foaming compositions comprising an emulsified oil phase, which is stable over time.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
According to a first aspect of the invention, it consists of a concentrate comprising: formula (I) and of at least one alkylglycoside of formula (II): radical containing from 8 to 15 carbon atoms. radical containing from 16 to 22 carbon atoms. and 10, R.sub.1 OH, R.sub.1 being a saturated or unsaturated linear or branched aliphatic radical containing from 8 to 22 carbon atoms.
The concentrate according to the invention may be used in particular as a pearling agent in order to provide a pearling effect which is homogeneous and stable over time. This is entirely surprising insofar as compositions such as those described in the application for patent WO 92/06778 mentioned above cannot impart such a pearling effect.
The alkylglycosides of formulae (I) and (II) may contain, as saccharide residue G or G', a glucose, mannose, galactose, idose, arabinose, xylose, ribose, gulose, lyxose or fructose residue. Advantageously, G and G' are identical and each represent a glucose residue. G and G' may be in .alpha. or .beta. anomeric form, and the saccharide unit may be in furanoside or pyranoside form.
The indices x and x' represent the average degree of polymerization of the saccharide residue. They preferably represent a number between 1.05 and 2.5, more preferably between 1.05 and 1.35.
It is noted that, when at least one of x and x' is equal to 1, the corresponding alkylglycoside may be classified as an alkylmonoglycoside. When one of x or of x' is greater than 1, the corresponding alkylglycoside may be classified as an alkylpolyglycoside.
Within the concentrate according to the invention, the weight ratio between the said alkylglycosides of formula (I) and those of formu
