Embodiment 1

[0144] Embodiment 1: Composition for steel plate degreasing

[0145] Degreasing of steel plates covered with a homogeneous film of different lubricating oils, lubricants or cutting oils usually used directly in the metalworking industry.

[0146] Compare the degreasing effectiveness of the following compositions:

[0147] - Composition 1: Trichlorethylene (TCE) sold by Riedel-De Haёn with reference number 24254,

[0148] - Composition 2: Dichloromethane (DCM) sold by Riedel-De Haёn with reference number 34488,

[0149] - Composition 3: dipentene (DP) sold by Fluka with reference number 42560,

[0150] - Composition 4: ethyl lactate (EL) sold by Sigma Aldrich,

[0151] - Composition 5: dimethylisosorbide (DMI) in the form of a colorless, odorless and slightly viscous solution prepared by the applicant company, said solution having a purity of about 99.6% of dimethylisosorbide,

[0152] - composition 6: a mixture of component DMI of composition 5 and component DP of composit...

Embodiment 2

[0192] Example 2: Latex-based film-forming composition

[0193] The properties of the following liquid compositions as binders for the preparation of latexes for water-based paints were compared:

[0194] - Composition A: 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, sold under the trade name Nexcoat(R) 795 by Perstorb Oxo, currently used as a combination agent. This product is a glycol ether derivative,

[0195] - Composition B: a mixture of butyl glutarate, butyl succinate and butyl adipate, sold under the trade name DBE IB(R) by Invista,

[0196] - Composition C: Dimethylisosorbide (DMI) prepared by the applicant company, in the form of a colorless, odorless and slightly viscous solution, the purity of DMI is about 99.6%,

[0197] - Composition D: a mixture of composition A (Nexcoat(R) 795) and composition C (DMI) in equal parts by weight,

[0198] - Composition E: a mixture of composition B (DBE-IB(R)) and composition C (DMI) in equal parts by weight.

[0199] The f...

Embodiment 3

[0221] Example 3: Concentrated Liquid Compositions for Extremely Biodegradable Processing Fluids

[0222] The emulsion was prepared from a composition comprising essentially by weight: 25% water, 30.8% rapeseed oil methyl ester (compound B) sold by Novance under the brand name Lubrisorb(R) 92665, 16.3% The dimethylisosorbide (DMI) composition (compound A) prepared by the company and described in the preceding examples, 15.4% of β-cyclodextrin sold by the applicant company under the brand KLEPTOSE(R), 10% of etchant and 1.5% of a sorbitan-derived surfactant.

[0223] The emulsion is prepared by mixing on a colloid attritor an aqueous phase consisting of water, beta-cyclodextrin and a portion of surfactant, and an oily phase consisting of the other components as described above Composition, including rapeseed oil methyl ester and DMI.

[0224] Apparently, the resulting emulsion is slightly viscous, easily dilutable with water, stable over time, and safe because it does not con...

Abstract

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.

Description

technical field [0001] The subject of the present invention is a method for the surface treatment of a material other than the human body, said material being chosen from metals and fibrous materials, said method comprising bringing said metal or fibrous material into contact with a composition comprising at least one A dianhydrohexitol ether, preferably dimethylisosorbide ("DMI") or dimethylisoidide ("DMIi"). Background technique [0002] Of the dicanhydrohexitol ethers known for more than 50 years, DMI, are those that have formed the subject of the most extensive research in terms of preparation and applications. The compound is particularly suggested for use in human treatment as a vectoring agent for active ingredients to allow active ingredients to reach targets inside the human body more efficiently. It is used in particular as a "skin penetrant" in order to improve the penetration of active ingredients into the proteinaceous (keratin) surface layer of the epidermis. ...
