Abstract

The invention relates to compounds of formula (I),in which R1, R2, A and n are as defined. The invention also relates to mineral or organic salts thereof; the use of the compounds of formula (I) and/or of one of the salts thereof as a surfactant, a wetting agent, a detergent, an emulsifying agent, a dispersant, a corrosion inhibitor, and the like; and to compositions comprising at least one compound of formula (I) and/or of one of the salts thereof.

First claim

The invention claimed is:

1. A composition comprising at least one compound of formula (I) and/or a salt thereof, alone or as a mixture, with one or more aqueous, organic or aqueous-organic solvents, and optionally one or more additives and fillers,

wherein:
R 1 and R 2 , which may be identical or different, represent, independently of each other, a linear, branched or cyclic, saturated or unsaturated hydrocarbon-based group, comprising from 1 to 6 carbon atoms, where the sum of the carbon atoms of the groups R 1 and R 2 ranges from 2 to 7, R 1 and R 2 optionally forming, together with the carbon atom that bears R 1 and R 2 , a 6-, 7- or 8-membered ring;
A represents a sequence of one or more units chosen from ethylene oxide, propylene oxide and butylene oxide units, and mixtures thereof; and
n is an integer between, limits inclusive, 2 and 100.

2. The composition as claimed in claim 1 , wherein the compound of formula (I) is in the form of a salt with a metal cation or with an organic compound.

3. The composition as claimed in claim 1 , wherein the compound of formula (I) is in the form of a salt with a alkali metal cation or with an alkaline earth metal cation.

4. The composition as claimed in claim 1 , wherein n in the compound of formula (I) is between, limits inclusive, 2 and 75.

5. The composition as claimed in claim 1 , wherein n in the compound of formula (I) is between, limits inclusive, 2 and 50.

6. The composition as claimed in claim 1 , wherein n in the compound of formula (I) ranges from 3 to 15.

7. The composition as claimed in claim 1 , wherein the compound of formula (I) is in the form of a salt corresponding to formula (II) below:

wherein:
M x+ is a cationic group bearing at least one cation chosen from an ammonium cation, a metal cation, a nitrogen cation, a boron cation and a phosphorus cation, and

x is an integer ranging from 1 to 7.
