| Résumé : |
Fatliquors for leather are usually very complex products. The major part of a natural based leather fatliquor consists of processed natural oils or substances derived from them. Furthermore, there can be emulsifiers, crude oils, antioxidants and various auxiliaries improving the penetration of the lubricating components and/or the stability of the formulation.
Fish oil has for many decades been the most prominent raw material used for leather fatliquors. The main advantage of fish oil in application is the high level of softness it creates in leather. By means of sulphitationor sulphation, fish oil can easily be transformed into the anionic, lubricating material which effectively prevents the leather fibres from sticking together.
With the premise to produce eco-friendly leather articles, one has to ask, how sustainable is the use of fish oil in comparison with its most important alternative, vegetable oils ? This paper provides an overview of the sustainability of both oils and the advantages of replacing fish oil with alternatives that have a better eco-profile. |
