Neomenthol, also known by its chemical name (1R, 2R, 5S)-rel-5-Methyl-2-(1-methylethyl)-cyclohexanol or (+-)-Neomenthol, is a compound primarily used in the cosmetic industry for its perfuming properties. This ingredient is a stereoisomer of menthol, meaning it shares the same molecular formula but differs in the arrangement of its atoms. Neomenthol is often derived from natural sources such as peppermint oil, but it can also be synthesized in a laboratory setting.
The history of neomenthol in cosmetics dates back to the early 20th century when the demand for refreshing and aromatic compounds began to rise. Its cooling and minty scent made it a popular choice for a variety of personal care products, from lotions to shampoos. Over time, advancements in chemistry allowed for the more efficient extraction and synthesis of neomenthol, making it more accessible and affordable for widespread use.
The production of neomenthol typically involves the hydrogenation of pulegone or the isomerization of menthol. These processes can be carried out through various chemical reactions that rearrange the molecular structure to produce neomenthol. The resulting compound is then purified and incorporated into cosmetic formulations to enhance their fragrance profile.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Neomenthol:
Neomenthol is primarily used in cosmetics for its perfuming properties. This means it is added to products to impart a pleasant scent. The refreshing and minty aroma of Neomenthol can enhance the sensory experience of using a cosmetic product, making it more enjoyable to apply. Whether it’s in a lotion, shampoo, or body wash, the inclusion of Neomenthol can make the product smell invigorating and fresh, which can be particularly appealing in personal care routines.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Neomenthol is generally considered safe for use in cosmetic products, but like any ingredient, it may not be suitable for everyone. It is important to be aware of its allergenic potential and the possible side effects associated with its topical application.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of neomenthol during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to neomenthol are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to conduct a patch test before widespread usage of any product containing neomenthol.
Neomenthol has a comedogenic rating of 1, which means it is considered to be very low on the scale of pore-clogging potential. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to contribute to these skin issues.
