What Is Polyglyceryl-6 Tetrabehenate?
Polyglyceryl-6 Tetrabehenate is a plant-derived ester created by linking six glycerin molecules to four molecules of behenic acid, a long-chain fatty acid most often sourced from canola or peanut oil. This combination yields a large, mild surfactant molecule that is friendly to both skin and the environment.
Polyglyceryl esters began gaining popularity in the early 2000s when formulators searched for greener alternatives to traditional polyethylene glycol (PEG) emulsifiers. Because glycerin and fatty acids come from renewable vegetable oils, these ingredients fit the bill for brands that want biodegradable, non-ethoxylated options.
The manufacturing process starts with heating glycerin so the molecules join together and form polyglycerin. In a separate step, behenic acid is activated and then esterified with the polyglycerin backbone. Careful control of temperature and catalysts results in the targeted “six-to-four” structure that balances oil and water affinity.
Thanks to its gentle nature and strong emulsifying power, Polyglyceryl-6 Tetrabehenate shows up in rich moisturizers, sunscreen creams, color-stay foundations, cleansing balms, stick deodorants, lipsticks and face masks where a stable, velvety texture is prized.
Polyglyceryl-6 Tetrabehenate’s Cosmetic Benefits/Uses
This ingredient plays one main role in formulations, yet that single job delivers several practical advantages for both the product and the user.
Emulsifying: Polyglyceryl-6 Tetrabehenate helps oil and water mix evenly, creating smooth lotions and creams that resist separating over time. Its large, naturally derived structure forms a flexible film around tiny oil droplets, locking in stability without the stickiness sometimes associated with synthetic surfactants. A well-built emulsion spreads easily, feels lightweight on skin and allows active ingredients to be distributed uniformly, improving overall performance and user satisfaction.
Who Can Use Polyglyceryl-6 Tetrabehenate
Polyglyceryl-6 Tetrabehenate is generally well tolerated by all skin types. Dry, normal and combination skin benefit most from the cushioning feel it adds to creams, while oily or very acne-prone complexions may find thick formulas containing high levels of this ingredient a bit rich. The molecule itself is lightweight and nonocclusive, so any heaviness usually comes from the overall product texture rather than the emulsifier.
Because it is manufactured from plant glycerin and vegetable-derived behenic acid, it is suitable for vegans and vegetarians. No animal inputs or by-products are used in standard production.
The Cosmetic Ingredient Review panel classifies this material as safe for use during pregnancy and breastfeeding when formulated within typical concentrations. That said, this is not medical advice and anyone who is pregnant or nursing should run new skincare products past their physician to be sure they meet individual health needs.
Polyglyceryl-6 Tetrabehenate does not increase photosensitivity, so it will not make skin more prone to sunburn. It also plays well with common actives such as retinoids, vitamin C and AHAs because it carries no charge and stays stable across a wide pH range.
Potential Side Effects/Adverse Reactions
Side effects from topical Polyglyceryl-6 Tetrabehenate can vary from person to person. The following list covers potential reactions, yet most users will not experience any issues when the ingredient is used correctly in a finished formula.
- Mild stinging or redness on very sensitive skin
- Contact dermatitis in individuals with an existing allergy to fatty acids derived from peanut or canola oil
- Breakouts or a feeling of heaviness in those who are extremely acne prone if the overall product is rich in oils or waxes
If any uncomfortable reaction occurs discontinue use and consult a qualified healthcare professional.
Comedogenic Rating
Rating: 1 / 5
Polyglyceryl-6 Tetrabehenate scores low because its bulky glycerin backbone keeps it from slipping into pores the way smaller, straight fatty acids can. It forms a light surface film that helps oils and water stay blended yet is not highly occlusive, so sebum can still flow out. While behenic acid on its own can edge toward pore clogging, the esterification process reduces that risk and typical use levels in formulas remain modest.
Overall the ingredient is generally suitable for skin that is prone to acne or breakouts, though the total oil load of the finished product still matters.
If you are extremely sensitive to long chain fatty acids or very heavy creams you may still prefer lightweight emulsions that use lower percentages of this material.
Summary
Polyglyceryl-6 Tetrabehenate is first and foremost an emulsifier that bridges oil and water. Its six-unit glycerin spine loves water while the four behenic acid tails love oil, so together they arrange themselves at the interface and keep a formula smooth, stable and pleasant to spread. This same structure also adds a soft, cushiony feel without greasiness.
Although it is not yet a household name, the push for plant based, PEG-free and biodegradable ingredients has made it increasingly popular among clean beauty and dermatologist led brands alike. You will most often spot it in richer creams, color cosmetics and hybrid sunscreen-moisturizer textures.
Safety data show it is non irritating for the vast majority of users, vegan friendly and safe during pregnancy when used at normal cosmetic levels. As with any new skincare ingredient it is wise to patch test a product first and monitor how your skin responds, particularly if you have a history of sensitivities.
