Glycols are a class of alcohols that contain two hydroxyl groups, which can also be called a diols.
Hexylene glycol is a clear, hygroscopic liquid with a mild, sweet odor.
Hexylene glycol is most often synthetically produced.
Hexylene glycol is manufactured by the condensation of 2 molecules of acetone to produce diacetone alcohol, which is further hydrogenated to produce hexylene glycol. This is then purified.
Hexylene glycol is used in the formulation of hair and bath products, eye and facial makeup, fragrances, personal cleanliness products, and shaving and skin care products at concentrations ranging from 0.1% – 25%.
Hexylene glycol as a surfactant helps to cleanse and moisturize the skin as well as thinning out the formulation to improve absorption, texture and allow other ingredients to work better.

Functions Of Hexylene Glycol
Hexylene glycol is added to cosmetics and skincare products based on its functions as a surfactant, an emulsifier, and a viscosity-reducing agent.
Surfactant
Surfactant is the short term for surface active agents.
Surfactants are compounds that lower the surface tension between two substances.
In skincare products, surfactants work to lift dirt, oil and fats from the skin, allowing them to be washed away.
This is possible because while one end of the surfactant molecule is attracted to water, the other end is attracted to oil.
Thus, surfactants attract the oil, dirt, and other impurities that have accumulated on your skin during the day and wash them away.
Due to these properties, hexylene glycol can be found in many different cleansers and body washes.
Emulsifier
Hexylene glycol also functions as an emulsifier.
An emulsifier is needed for products that contain both water and oil components, for example, when oils are added to a water-based formula.
According to EFEMA, when water and oil are mixed together and vigorously shaken, a dispersion of oil droplets in water is formed.
When shaking stops, however, the two phases can start to separate.
To address this problem, an emulsifier like hexylene glycol can be added to the system, which helps the droplets remain dispersed and produces an even and stable formulation.
As an emulsifier, hexylene glycol consists of a water-loving hydrophilic head and an oil-loving hydrophobic tail.
The hydrophilic head is attracted to the water and the hydrophobic tail to the oil.
Once again, hexylene glycol reduces the surface tension by positioning itself between the oil and water, which has a stabilizing effect on the product.
Thinning
Finally, hexylene glycol functions as a viscosity-reducing agent.
The term viscosity corresponds to the concept of “thickness”, for example, honey has a higher viscosity than water.
As a viscosity-reducing agent, hexylene glycol works to thin out heavy formulations and create a thinner, more spreadable product.

This property makes it an ideal choice as a surfactant and emulsifier.
The emulsifier is meant to hold water and oil together to make the products more stable.
Hexylene glycol is used to decrease the viscosity of the product.
So, in high viscosity product, hexylene glycol is used to “thin” the formulation.
Hexylene glycol is a diol (with two hydroxy groups at 2 and 4 positions), a colorless liquid with a mildly sweet odor and oily consistency.
In nature, Hexylene glycol is found in the tobacco plant (Nicotiana tabacum).
