USE OF AN OIL COMPRISING A POLAR GROUP
AS AID FOR THE DEPOSITION OF NON-IONIZABLE APOLARE OIL
The subject of the present invention is the use in an aqueous formula of an oil comprising one or more polar groups but no cationic group, as an aid for the deposition of an oil which does not comprise an ionizable group in a pH range from 2 to at 12 ni neutral polar group.

 In many fields, whether they concern the treatment of the skin and / or the hair, or the treatment of textiles or the manufacture of paper, it is often sought to deposit a substance on a surface so as to modify it. the state.

 Thus, in the particular field of cosmetics, it can be sought to deposit a non-polar hydrophobic compound, such as an oil for example, on the hair so as to protect the surface or to treat the damaged parts. The difficulty encountered is related to the fact that the deposit is not sufficient, and in this case, the more marked that the affected area is damaged (chemical treatment type fading or mechanical).

 In international application WO 99/29286, it has been proposed to use aminated silicone oils combined with hydroxylated silicone oils, so as to increase the deposit on the damaged hair. The use of these amino silicones is, however, particularly expensive and may be ineffective in certain formulations.

 The present invention relates to the use of a dispersion comprising a nonionizable apolary oil combined with a compound which assists the deposition of said oil on different surfaces.

 In addition, the present invention makes it possible to increase the quantities of oil deposited, whether on the rather hydrophilic surfaces than on the hydrophobic surfaces.

These and other objects are achieved by the present invention which therefore relates to the use in an aqueous formulation, of a polar oil (A) defined as: (i) comprising at least one polar group selected from hydroxyl functions ether, amide, ester, carboxylic, phosphoric, phosphonic, sulfuric, sulfonic, sulfosuccinic, or the corresponding salts; (ii) and not comprising a cationic group at a pH of between 2 and 13;

 as an aid for the deposition on a surface of a dispersion of an apolar oil (B) defined as non-ionizable at a pH of between 2 and 12 and not comprising any of the aforementioned polar groups (i).

destinées à la cosmétique, la détergence, le traitement des textiles ou du papier, les revêtements peinture. It likewise relates to the use of dispersion in formulations

intended for cosmetics, detergents, textile or paper treatments, paint coatings.

 But other features and advantages of the present invention will appear more clearly on reading the description which follows.

 As has been indicated before, the subject of the invention is the use of a dispersion of an oil (A) comprising (i) at least one polar group chosen from hydroxyl, ether, amide, ester and carboxylic functions. phosphoric, phosphonic, sulfuric, sulfonic, sulfosuccinic, or the corresponding salts; and not comprising (ii) cationic group at a pH of from 2 to 13; as an aid for the deposition on a surface of a dispersion of apolare oil (B) defined as non-ionizable at a pH of between 2 and 12 and not including any of the polar groups (i) mentioned above.

 For the purposes of the present invention, the term "dispersion" covers the case where the dispersed phase is in solid (or pasty) form or in liquid form.

 In addition, the term oil will be used indifferently to denote compounds in liquid, pasty or solid form at room temperature. Preferably, the oil (B) used is in a liquid form at room temperature (20-300C).

This multiple emulsion can be of various natures. Thus, the oil droplets (B) may, according to one possibility, comprise an aqueous phase dispersed within the same droplets of oil (water-in-oil-in-water). Alternatively, the oil droplets (B) may be dispersed within droplets of another oil (oil-in-oil-in-water). The oil dispersion (B) can likewise be in the form of a dispersion of solid particles of oil. This is especially the case with oils with a melting point above room temperature (20 ° C). Waxes are an example.

 Furthermore, the average particle size (liquid or solid) of the oil dispersion (B) is more particularly less than or equal to 60 μm, in particular less than or equal to 30 μm, and preferably less than or equal to 2 μm.

<Desc / Clms Page number 3>

 Formulas 5 and 6 are in the form of oil-in-water direct emulsions and have a size of 1 μm.

 The deposition of the emulsions of each formula was quantified on a silanized glass plate by octadecyltrichlorosilane hydrophobic groups (procedure according to JB Brzoska, 1. Ben Azouz, F. Rondelez, Langmuir, 1994, 10, 4367).

 The deposits are measured at 25 ° C. in a laminar flow cell (microscopic observation (Zeiss * 50) of the deposit of the emulsions placed on the surface observed).

 The cell (55 * 13 * 0.6 mm3) is made of 2 hydrophobic glass plates separated by a Teflon blade.

 The flow rate in the cell is 50 ml / hour (laminar flow).

 An equilibrium surface coverage ratio (surface ratio of the emulsion and the total area) is measured.
