The information here describes the ingredient in general. Its possible sources may vary and do not necessarily show the origin or form used in a particular YUMA product. For product-specific information, check the relevant product page.
Just a few parts per million (ppm) of p-tert-Butylcyclohexanone are enough to significantly influence a fragrance, which is comparable to a single drop in an Olympic-sized swimming pool.
Perfumers use p-tert-Butylcyclohexanone as a key to unlock specific scent notes in complex compositions, particularly when they want to create the impression of patchouli without using the natural oil.
The use of synthetic ingredients like p-tert-Butylcyclohexanone contributes to sustainable perfumery by reducing the need to overexploit natural resources such as rare woods and endangered plants.
The IFRA Standards form an industry self-regulatory system. They may prohibit or restrict the use of particular fragrance ingredients, or set specifications, according to end use. The status below reflects the IFRA data recorded for this ingredient. It is not a product certification and does not replace applicable law or assessment of the finished product.
IFRA categories group end uses by the type and level of exposure. A restriction or maximum concentration applies only to the stated category and does not automatically apply to another use. Check the related IFRA document for the applicable Standard version and its full conditions.

The safety of p-tert-Butylcyclohexanone has been evaluated by the Research Institute for Fragrance Materials (RIFM), and a peer-reviewed safety assessment has been published. It was found to have the potential to cause skin sensitization in a small percentage of individuals. This means that in a limited number of people, repeated contact may cause a temporary reaction, including skin redness, rash or itching.
To prevent sensitization, RIFM has established a maximum acceptable concentration level for this ingredient, and the International Fragrance Association (IFRA) has set safe usage standards for p-tert-Butylcyclohexanone in household and personal care products. Although an ingredient may have the potential for skin sensitization, most people will not be affected. Everyone's skin is different, so consult a healthcare professional with any questions you may have.
