TETRAMETHYL-OCTANAL

Description

Tetramethyl-octanal, also known as ISO E Super, is a synthetic aroma chemical widely used in the fragrance industry and increasingly incorporated into haircare formulations. This versatile compound is characterized by its woody, amber-like scent with subtle floral notes. In haircare products, tetramethyl-octanal serves multiple purposes beyond its olfactory properties.

As a fixative, it enhances the longevity of other fragrances in hair products, ensuring a lasting scent. Its low molecular weight allows for efficient penetration into hair fibers, contributing to improved hair manageability and smoothness. Tetramethyl-octanal has been observed to have mild antioxidant properties, potentially offering protection against environmental stressors.

In shampoos and conditioners, this ingredient can help reduce static electricity and frizz, leading to smoother, more manageable hair. It also acts as an emollient, providing a silky feel to hair without excessive oiliness. While generally considered safe for use in cosmetics, some individuals may experience skin sensitization. As with any fragrance component, patch testing is recommended for those with sensitive skin or a history of allergic reactions to fragrances.
