Rexine is a material used widely as a substitute of leather. However, there is not much clarity on the materials used in its production. Sometimes, it is even referred to as "Artificial Leather". Does the production of raxine involve killing animals?

Rexine and other artificial leathers are cloth-backed plastics

In general, the whole point of artificial leathers is to not be animal skins, for either ethical or cost reasons. The cloth component is generally plant-derived (again for cost reasons), and modern plastics are purely synthetic.

If that's all you're worried about — that rexine might actually be animal skin — then you needn't worry about that. It's definitely not animal skin.

The Devil's in the details

However, every artificial leather uses its own production formula, and it's theoretically possible that minor chemical additives have an animal source.

Unfortunately, if all you know is that the material you're thinking of is called “rexine”, there's no way to know for certain, since that's not enough information to know what the material actually is and track down its production formula. Brand-name Rexine is a specific type of artificial leather produced by Rexine LTD of the United Kingdom, but much like “kleenex” in the United States, the brand name “Rexine” has suffered from brand genericisation, and now many different materials are popularly called “rexine”.

Brand-name Rexine: probably vegan

Based on Wikipedia's record of the formula, actual brand-name Rexine is probably produced without animal products: it's made from nitrocellulose (which is itself made from cellulose and laboratory-produced, mineral-sourced nitric acid), camphor oil, pigment and alcohol.

The “probably” is because of the non-specific use of “pigment”: the vast majority of industrial processes use synthetic pigments rather than naturally-derived ones, due to greater colour-fastness and lower cost, but since animal-sourced pigments do exist, it's possible — however unlikely — that some colours of Rexine are coloured with an animal-derived pigment.

Buyer beware, and do more research

For all other artificial leathers, the specific manufacturer must be identified, and this can't be done just by finding out what trade name the material goes under. To find out exactly what a specific artificial leather is made out of, you'll have to contact the manufacturer directly and inquire about their formula's sources.

Conclusion

Artificial leathers are definitely not animal skin, and at that “large scale”, they're not animal products.

It's highly likely that any given artificial leather brand does not contain any animal-derived ingredients. For many artificial leather brands, this is the entire purpose. However, it's possible that a given artificial leather brand might use some innocuous chemical as part of its plastic production, which might have some animal source somewhere in its own production history. This is unlikely, but a possibility. If 100% vegan artificial leather is the goal, then the only way to be sure is to talk to the manufacturer of the specific artificial leather and get their response on how they source all ingredients for their formula.
