What it is
Butyl Hydroxycyclohexane Carboxylate is a synthetic ester derived from cyclohexane and butanol. It is designed to activate the same skin receptors as menthol (TRPM8) but with less irritation and no strong odor, making it a popular alternative in cooling formulations.
How it works
It works by binding to TRPM8 receptors in the skin, which are the same receptors that detect cool temperatures. This triggers a mild, pleasant cooling sensation without actually lowering skin temperature, helping to soothe and refresh the skin.
Pros
Gentle cooling
Provides a mild, pleasant cooling effect without the strong odor or irritation commonly associated with menthol, making it suitable for sensitive skin.
Versatile use
Can be added to a wide range of products like serums, moisturizers, and eye creams to enhance the sensory experience without altering the product's scent.
Cons and cautions
Synthetic origin
As a lab-made compound, it may not appeal to consumers seeking exclusively natural or plant-derived ingredients.
Potential tingling
A small number of users may experience a mild tingling or cooling sensation that could be uncomfortable if they are unaccustomed to cooling agents.
Best for
- Anyone looking for a refreshing, cooling sensation in skincare
- People with sensitive skin who find menthol too harsh
Use caution if
- Those who prefer only natural ingredients
- Individuals with known allergies to synthetic esters
