Abstract

The present invention relates to a caprolactam-based fatty amide additive having an amine or salified amine ending useful as a hydrogelator for aqueous compositions.

First claim

1 . Gelator additive based on fatty amide which is a product of an addition reaction of a fatty amine R 1 NH 2 with caprolactam with an end amine functional group in amine form or in salified ammonium salt form, by neutralization of said amine functional group by a neutralizing agent, wherein said additive comprises a mixture of 3 different amide compounds resulting from said reaction and which are characterized by the number n of incorporated caprolactam units, which is respectively L 2 and 3, with a mean number II of units (mean per molecule) ranging from 0.8 to 3.

2 . Additive according to claim 1 , wherein said 3 amide compounds are defined according to the following formula (I) and respectively correspond to n=1, n=2 and n=3
R 1 —NH—[—C(═O)(CH 2 ) 5 NH] n -1-C(═O)(CH 2 ) 5 —Y  (I)

with Y being —NH 2 or —NH 3 + X − , if the amine is in salified form and with X − being an organic or inorganic counteranion related to the acid neutralizing agent used, X—H.

3 . Additive according to claim 1 wherein said fatty amine comprises a number of carbon atoms from 10 to 24.

4 . Additive according to claim 1 wherein said amine functional group is in salified form and said neutralizing agent is selected from the group consisting of organic and inorganic acids.

5 . Additive according to claim 1 wherein said additive is a micronized powder having a volume-average size of less than 50 μm.

6 . Additive according to claim 1 wherein it is in gel form in water or in gel form in organic solvent, at a content by weight of less than 5% by weight.

7 . Process for the preparation of an additive according to claim 1 comprising a stage of an addition reaction between fatty amine R 1 NH 2 and caprolactam with a molar ratio of said caprolactam with respect to the said fatty amine from 0.8 to 3 said process not comprising separation or purification stages.

8 . An aqueous composition or a composition in an organic solvent medium comprising at least one additive according to claim 1 .

9 . Composition according to claim 8 which is an aqueous composition having a pH of less than 5.

10 . Composition according to claim 8 which is an aqueous surfactant.

11 . Aqueous composition according to claim 8 which is an aqueous organic binder composition, a coating, an adhesive a cosmetic composition, or an aqueous composition for the treatment of fibres or textiles.

12 . (canceled)

13 . Composition according to claim 8 , which is a composition in an organic solvent in the organogel form, or is a coating composition, an adhesive composition, a mastic or leaktightness agent, stripping agent composition, or a moulding composition.
