What Is Lauryl/Myristyl Glycol Hydroxypropyl Ether?
Lauryl/Myristyl Glycol Hydroxypropyl Ether is a synthetic ingredient created by reacting medium-chain fatty alcohols, mainly lauryl (C12) and myristyl (C14), with propylene oxide to introduce a hydroxypropyl group. The result is a mild, water-dispersible molecule that combines the cleansing ability of fatty alcohols with the solubility boost provided by the ether linkage. While plant oils such as coconut and palm often supply the starting fatty alcohols, the final ingredient is produced in a lab under controlled conditions to ensure consistent purity.
Its use in cosmetics grew in the late 1990s when formulators looked for gentler alternatives to traditional sulfates. By attaching a hydroxypropyl group, chemists managed to lower the irritation potential typical of raw fatty alcohols while improving foaming performance. Today the ingredient is manufactured through a multi-step process: fatty alcohols are first isolated, then reacted with propylene oxide in the presence of a catalyst, followed by purification and quality checks.
You will most often see Lauryl/Myristyl Glycol Hydroxypropyl Ether in rinse-off products such as facial cleansers, body washes and shampoos. It also appears in bubble baths, shaving creams and foaming masks where a rich lather is desirable but skin comfort is still a priority.
Lauryl/Myristyl Glycol Hydroxypropyl Ether’s Cosmetic Benefits/Uses
This ingredient supports a formula in two main ways
- Cleansing: Its amphiphilic structure lifts away oil, dirt and makeup without stripping the skin’s natural moisture, leaving a fresh comfortable feel after rinsing
- Foam Boosting: It enhances the volume, stability and creaminess of lather, making cleansers and shampoos feel more luxurious and helping the product spread evenly across skin or hair
Who Can Use Lauryl/Myristyl Glycol Hydroxypropyl Ether
This gentle cleanser works well for most skin types, including oily, combination, normal and even sensitive or reactive skin, because it removes grime without aggressively stripping natural oils. People with very dry or compromised skin may still want to pair it with richer moisturizers, but the ingredient itself is not inherently drying.
Since the fatty alcohols used in its production usually come from plant oils such as coconut or palm, Lauryl/Myristyl Glycol Hydroxypropyl Ether is generally suitable for vegans and vegetarians. Anyone strictly avoiding palm derivatives should check the brand’s sourcing information to be sure.
There is no evidence that the ingredient poses special risks to women who are pregnant or breastfeeding when used topically in rinse-off products. This is not medical advice and anyone expecting or nursing should review skincare choices with a qualified healthcare professional.
The molecule is not known to cause photosensitivity, so it will not make skin more prone to sunburn. It is also safe for color-treated hair because it is milder than traditional sulfates.
Potential Side Effects/Adverse Reactions
Reactions to Lauryl/Myristyl Glycol Hydroxypropyl Ether vary from person to person. The following are potential side effects that could occur, though most users experience none of them when the ingredient is properly formulated and used:
- Mild skin irritation such as redness or itching
- Dryness or tightness if the product is left on the skin for an extended time
- Eye stinging if the cleanser accidentally gets into the eyes
- Allergic contact dermatitis in individuals sensitive to fatty alcohol derivatives
If any of these reactions occur stop using the product and seek advice from a healthcare professional
Comedogenic Rating
Rating: 1/5
Lauryl/Myristyl Glycol Hydroxypropyl Ether is highly water dispersible and usually appears in rinse-off formulas, which cuts down the time it stays on skin and lowers the risk of pore blockage. Its modified structure is less oily than raw fatty alcohols, so it is considered practically non-comedogenic for most users.
Suitable for acne-prone skin, though individual experiences can differ.
Because it is typically combined with other mild surfactants, any breakout concerns are more likely linked to the overall formula or to leave-on products layered afterward rather than to this ingredient itself.
Summary
Lauryl/Myristyl Glycol Hydroxypropyl Ether serves two key roles: it cleans by surrounding and lifting away oil and dirt, and it boosts foam so cleansers and shampoos feel rich and spread easily. Its amphiphilic design lets the hydrophobic fatty chain grab grime while the hydroxypropyl portion keeps everything suspended in water for a quick rinse.
While not as famous as sulfates or betaines, it enjoys steady use among brands looking for gentle yet effective lather, especially in products marketed for sensitive skin.
Overall safety data are strong, with low irritation and almost no comedogenic risk when used as directed. As with any new skincare product, it is wise to do a small patch test first to check personal tolerance.
