What Is Polyglyceryl-35 Lauryl Ether?
Polyglyceryl-35 Lauryl Ether is a plant-derived ingredient created by joining lauryl alcohol, usually sourced from coconut or sustainable palm, with a long chain of 35 glycerin units. The result is a mild, water-loving molecule that helps oil and water stay mixed. Interest in greener surfactants and gentler emulsifiers grew in the late 1990s, prompting formulators to explore polyglycerol derivatives like this one. To make it, chemists first link glycerin molecules together through heat and a food-grade catalyst, then attach lauryl alcohol to the polymer in a controlled reaction that forms an ether bond. The finished material appears as a clear to pale yellow liquid or soft solid, easily dispersed in water.
You will most often spot Polyglyceryl-35 Lauryl Ether in facial cleansers, micellar waters, lightweight moisturizers, sunscreens, makeup removers, baby toiletries and leave-on lotions where a gentle cleansing or stabilizing action is desired.
Polyglyceryl-35 Lauryl Ether’s Cosmetic Benefits/Uses
This multitasking ingredient improves both the texture and the performance of many personal care products.
- Emulsion stabilising: Keeps oil and water phases from separating so creams stay smooth and uniform throughout their shelf life. A stable emulsion feels nicer on the skin and delivers active ingredients more evenly.
- Cleansing: Acts as a mild surfactant that lifts away dirt, excess oil and makeup without stripping the skin’s natural barrier, making formulas gentler and suitable for daily use.
Who Can Use Polyglyceryl-35 Lauryl Ether
This mild emulsifier suits most skin types including dry, oily, combination, sensitive and acne-prone skin because it cleanses without stripping natural lipids and has a very low irritation profile. Those with known allergies to coconut or palm derivatives should check the full ingredient list since the lauryl portion is sourced from these plants.
Polyglyceryl-35 Lauryl Ether is manufactured from vegetable glycerin and plant-based fatty alcohol so it is generally considered suitable for vegans and vegetarians. As with any raw material, certification policies can vary by supplier so strict lifestyle followers may wish to confirm that no animal by-products are used at any stage of production.
The ingredient is regarded as low risk for expectant or nursing mothers because it does not readily penetrate the skin or interfere with hormones. This is not medical advice and anyone who is pregnant or breastfeeding should discuss new skincare products with a qualified healthcare provider for extra peace of mind.
It does not increase photosensitivity and can be used morning or night without affecting sun tolerance. Because it is gentle enough for baby washes and eye makeup removers it is often included in formulas aimed at delicate skin.
Potential Side Effects/Adverse Reactions
Reactions to topical Polyglyceryl-35 Lauryl Ether differ from person to person. The points below outline potential side effects which remain uncommon when the ingredient is used correctly in a finished cosmetic product.
- Mild skin irritation in very sensitive individuals
- Allergic contact dermatitis in people with specific coconut or palm allergies
- Temporary eye stinging or watering if the product accidentally gets into the eyes
- Occasional dryness or feeling of tightness when used in high concentrations or in multiple products layered together
If any of these reactions occur discontinue use immediately and consult a medical professional if symptoms persist or worsen.
Comedogenic Rating
Rating: 1/5
Polyglyceryl-35 Lauryl Ether is highly water soluble and has a large, bulky structure that does not readily penetrate pores or mix with skin sebum. These properties keep it from building up inside follicles, giving it a very low likelihood of clogging pores.
Because of this low rating it is generally considered suitable for acne-prone or breakout-prone skin.
As with any surfactant, the finished formula matters; heavy oils or rich butters paired with it could still raise the overall comedogenic risk, so always look at the product as a whole.
Summary
Polyglyceryl-35 Lauryl Ether mainly stabilises emulsions and provides gentle cleansing. The multi-glycerin backbone attracts water while the lauryl tail binds to oils, letting it sit at the oil-water interface to keep creams homogenous and sweep away dirt when used in cleansers.
It is not the most famous ingredient on store shelves but its plant origin, mildness and versatility have made it steadily more popular with formulators focused on clean beauty and baby care.
Safety data show a very low irritation and sensitisation potential, and regulatory bodies allow it without special restrictions. Still, everyone’s skin is unique so it is wise to patch test any new product containing Polyglyceryl-35 Lauryl Ether before full-face use just to be safe.
