Gamma Methyl Ionone

This is a widely used synthetic fragrancing ingredient, particularly used in production of personal care products, perfumes and as a fragrancing ingredient for cleaning products.

Khush Ingredients sources this key material from outside the EU where producers declare that they are against animal testing so it is suitable for cosmetics use. However, this does mean that Khush Ingredients has to pay import duty into the EU so pricing is a little higher than European sourced material.

Our principal source is from China, where 180kg drums are available.

Supply route is approximately 8 weeks from producer and goods are shipped and delivered using ADR transport for a UN3082 class 9 material.
