The present invention relates to a sensory emulsifying composition, in particular for cosmetic use, capable of obtaining a liquid oil-in-water-type emulsion comprising at least one cyclodextrin in the form of solid particles, said particles having a volumetric average particle size d(4,3), measured by laser granulometry, of between 2 and 20 μm, preferably between 3 and 12 μm, and more preferably between 4 and 8 μm, and at least one emulsifier of natural origin selected from water-in-oil emulsifiers, having a hydrophilic-lipophilic balance (HLB) of less than 8.

Emulsifying composition comprising a water-in-oil emulsifier and a cyclodextrin of selected particle size, capable of providing an oil-in-water emulsion with improved sensory effects for cosmetic use

The present application pertains to the field of cosmetics, more specifically the field of topical care of bad odors, by the action of a bactericidal and/or bacteriostatic topical composition, and of capturing odors. The topical composition according to the invention comprises at least one cyclodextrin, a 1,4-3, 6-dianhydrohexitol and/or a 1,4-3, 6-dianhydrohexitol derivative. It can be useful for the oral sphere, but also for areas of the skin where bad odors may develop due to microbial activity, namely the underarms, crotch and feet. Preferably, the topical composition of the invention is used for treating the oral sphere, most preferably for treating halitosis.

Topical composition for treating bad body odors, in particular halitosis

The application relates to an emulsifying composition, in particular for cosmetic use, allowing an oil-in-water emulsion (O/W) to be obtained, the emulsion comprising at least one cyclodextrin and at least one O/W emulsifier of natural origin with a hydrophilic-lipophilic balance value (HLB) of more than 8. The O/W emulsifier of natural origin can be selected from alkyl polyglucosides, mixtures of at least one alkyl polyglucoside and at least one fatty alcohol, and non-ethoxylated polyol fatty esters. The application also relates to a composition of the Pickering emulsion type, in particular for cosmetic use, containing the emulsifying composition according to the invention, and to the process for preparing such a composition of the O/W Pickering emulsion type, in particular at low temperatures.

The invention relates to the use of a native or modified leguminous starch for producing an adhesive labeling composition. Said leguminous starch has an amylose content ranging between 25 and 60 percent by weight (dry/dry) and can be embodied as pea starch, especially pea starch having an amylose content of at least 30 percent but less than 50 percent by weight. The adhesive composition can advantageously be used for labeling glass or plastic bottles and can contain another natural polysaccharide polymer or protein polymer in addition to the leguminous starch, for example another native or modified leguminous or non-leguminous starch, particularly a starch having an amylopectin content of at least 80 percent by weight (dry/dry). The use of a leguminous starch makes it possible to obtain labeling adhesives, optionally highly dry (&#x3e;40%) substances, which have excellent characteristics regarding stability during storage, rheology, and water resistance.

Use of a leguminous starch in an adhesive labeling composition

An adhesive composition, includes at least one vegetable starch the amylose content of which is between 30 and 60%. The invention further relates to the method for using the composition, including application thereof to lignocellulose materials, the forming of a panel and the hot pressing thereof. The emissions of formaldehyde vapor during the method are as low as possible. The invention further relates to the panels produced as above and in particular the panels emitting reduced amounts of formaldehyde into the atmosphere.

The invention relates to a surface treatment method, in which a material other than the human body, which is selected from metallic materials and fibrous materials, is brought into contact with a composition comprising at least one dianhydrohexitol ether (compound A). The dianhydrohexitol ether can be associated with a compound B which is selected from among solubilising agents, acid agents and alkaline agents. The fibrous material to undergo surface treatment is chosen from the following materials in particular, namely: wood materials, vegetable materials, paper materials and textile materials.

Described is the use, for preparing or treating bituminous compositions, of at least one compound selected among: esters of glycolic, lactic and gluconic acids, methylic, ethylic and isobutylic esters of glutaric, succinic and adipic acids, and ethers or esters of a product resulting from internal dehydration of a sugar, preferably a hydrogenated sugar. Also described is a method for preparing or treating such compositions and the resulting compositions.
