2-Hexenal is a strong yet pleasant ingredient with a bold, crisp presence in fragrance. It features green, leafy aroma notes accompanied by nuances of fresh fruit and spices. At very low concentrations, it adds a sense of freshness to various fragrance compositions, making it particularly useful for perfumers.
Although 2-hexenal can be extracted from natural sources such as apricots, citrus fruit, mango, sage, thyme and radish, it is often produced in laboratories using various methods. This approach helps conserve natural earth resources while allowing perfumers to use the unique properties of this ingredient in their creations.
2-Hexenal is responsible for the characteristic scent of freshly cut grass that many people associate with summer. When you mow your lawn, this compound is released into the air, creating that unforgettable summer smell!
In nature, 2-hexenal is part of a plant defense mechanism. It is released when leaves are damaged, acting as a chemical signal that warns neighboring plants of potential dangers and repels certain insects.
Scientists classify 2-hexenal in the family of green leaf volatiles, a group of molecules that play a significant role in ecology. These compounds not only contribute to the aromas we perceive, but also facilitate communication between plants and other organisms in the ecosystem.
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 2-hexenal has been evaluated by the Research Institute for Fragrance Materials (RIFM) and a relevant safety assessment has been published. It has been determined that there is a potential for skin sensitization in a small percentage of individuals. This means that in a limited number of people, repeated contact may cause a temporary reaction, such as 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 established safe-use standards for 2-hexenal 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 if you have any questions. The fragrance industry supports the disclosure of certain ingredients so that individuals who may already have an allergy can choose products suitable for them.
