Description
- The present invention relates to di-alkyl substituted imidazoline derivatives where the two alkyl groups are linked through an ester function to the imidazoline core. The di-alkyl substituted imidazoline derivatives of the present invention may also be used in compositions such as fabric care compositions and hair conditioning compositions.
- Supply and storage of fabric softening compositions and their individual ingredients in less developed countries can pose logistical problems. Oftentimes, the transportation of products is over long distances, using poor infrastructures, and in high temperatures. Also, due to limitations to resources in less developed countries, it is preferential that the used fabric conditioning compositions are readily biodegradable and have minimal environmental impact.
- Traditionally, fabric softening compositions have used dialkyl quaternary conditioning actives. However, a major drawback to these compounds is that they need to be stored and shipped with the addition of a dilution solvent. Considering the logistical issues associated with storage and shipping in less developed countries, it is preferable to not use solvents.
- Di-alkyl substituted imidazoline compounds are known in the art. Oftentimes they are used as fabric softening and hair conditioning actives. However, other industrial applications include the use as antistatic and as corrosion inhibitor. Given their lower melting point, the di-alkyl substituted imidazoline derivatives can be stored and shipped without the need to add a dilution solvent, leading to important logistical cost savings. They are also non-corrosive, meaning construction material of lower grade metallurgy can be utilised for manufacturing, storage and shipment equipment. Nevertheless, di-alkyl substituted imidazoline derivatives are not readily biodegradable, which is an undesirable characteristic of this class of compounds.
EP 345,842 A2 JP05-105670 JP06-228870 - There is a need in the art for fabric softening compositions that comprise readily biodegradable actives which do not form persistent monoalkyl substituted break-down products upon degradation. There is also a need for a fabric softening composition in which the fabric softening active can be easily and safely stored and transported over long distances using poor infrastructures and in high temperatures. Lastly there is a need for a fabric softening composition for use in less developed countries that comprises all of the above characteristics, but which is also in a consumer accepted product form.
- It was surprisingly found that granular fabric softening compositions comprising a di-alkyl substituted imidazole derivative according to the formula of claim 1 offered a fabric softening composition in which the softening active is readily biodegradable, and is in a consumer accepted product form. Also, the fabric softening active can be shipped safely and easily, in the absence of a dilution solvent.

- Groups A and B, both independently being O-(C=O)-, act as points of degradation, ensuring the diester derivative does not form a persistent monoalkyl species.
