Abstract

Quaternized monoalkyl compounds derived from fatty acids are described. The quats are produced from fatty acid materials which contain at least about 30% by weight of larger chains containing at least 20 carbons in length. Personal care products produced using these quats are also described.

Claims

1. A monoalkyl quat material comprising a quaternized monoalkyl amidoamine wherein said monoalkyl group has an iodine value of greater than 0 and includes at least about 30% of at least a C-20 fatty acid component by weight, said quaternized monoalkyl amidoamine being dissolved or dispersed in a solvent at a cationic activity of between about 25% and about 90%.

2. The monoalkyl quat material of claim 1 wherein said monoalkyl group has an iodine value of between greater than 0 and about 200.

3. The monoalkyl quat material of claim 2 wherein said monoalkyl quats and solvent are, when combined, in a liquid form at 25°

C.

4. The monoalkyl quat material of claims 1, 2 or 3 wherein said monoalkyl group is derived from the fatty acids contained in triglycerides, waxes or an oil selected from the group consisting of HEAR oil, cod liver oil, herring oil, menhaden oil, mustard seed oil, pilchard oil, hear oil, salmon oil, sardine oil, meadowfoam oil and shark liver oil.

5. The monoalkyl quat material of claims 1, 2 or 3 wherein said monoalkyl group is derived from the fatty acids selected from the group consisting of Eicosenoic acid, Eicosapentaenoic acid, Erucic acid, 1-2% Docosapentaenoic acid, Docosahexaenoic acid, Eicosatetraenoic acid, Tetrcosanoic acid, arachidic acid, behemic acid, gadoleic acid, arachadonic acid and culpodonic acid.

6. The monoalkyl quat material of claims 1, 2 or 3 further comprising a shampoo base, conditioner base, facial soap base, hair color base or body wash base said monoalkyl quats being provided in an amount of between about 0.1 and about 10% cationic activity by weight.

7. The monoalkyl quat material of claim 1 wherein said amidoamine includes an alkoxy, substituted alkoxy, alkyl, hydroxy or polyalkoxy group.

8. A personal care product comprising:

a shampoo base, conditioner base, facial soap base, hair color base, body wash base or liquid soap base and between about 0.1 to about 10% by activity of a monoalkyl quat material comprising a quaternized monoalkyl amidoamine wherein said monoalkyl group has an iodine value of greater than 0 and includes at least about 30% of at least a C-20 fatty acid component by weight, said quaternized monoalkyl amidoamine being dissolved or dispersed in a solvent.

9. The personal care product of claim 8 wherein said monoalkyl group is derived from the fatty acids contained in triglycerides, waxes or an oil selected from the group consisting of HEAR oil, cod liver oil, herring oil, menhaden oil, mustard seed oil, pilchard oil, hear oil, salmon oil, sardine oil, meadowfoam oil and shark liver oil.

10. The personal care product of claim 8 wherein said monoalkyl group is derived from the fatty acids selected from the group consisting of Eicosenoic acid, Eicosapentaenoic acid, Erucic acid, 1-2% Docosapentaenoic acid, Docosahexaenoic acid, Eicosatetraenoic acid, Tetrcosanoic acid, arachidic acid, behemic acid, gadoleic acid, arachadonic acid and culpodonic acid.
