​We don't claim 100% natural laundry formulas. This is mainly due to the ingredients available at the moment and product safety.

For example, our active cleaning agents come from natural sources, but during production it may be required that they are mixed with a processing aid, which may not be natural. So there may be trace elements left behind. This is the case with all ingredients of this kind, in just about every product on the market.

Also, sometimes we use nature identical ingredients, these are ingredients that have the exact same chemical structure as their natural counterparts, but it is more sustainable to product them in a lab, usually through a reaction process. There are also situations where an ingredient is derived from a natural source but though processing to create a usable cleaning ingredient, it is not different to what is found in nature.

As our formulas use so many naturally derived ingredients, they are susceptible to spoiling, so we need to use preservatives with a very broad spectrum of activity. There isn't a naturally derived option for this, so we use a safe synthetic version.

Our botanical fragrances are created by perfumers together with our scent obsessed founder Sam. Before we launch, we rigorously test on different fabrics to ensure a long lasting scent.

Yes. Non bio is the best laundry detergent for washing wool and delicates as these items contain enzymes that bio detergents may damage. All Wilton Laundry detergents are non bio.
