What Is Polyglyceryl-6 Behenate?
Polyglyceryl-6 Behenate is an ester created by linking six glycerin units to behenic acid, a fatty acid usually sourced from natural oils like rapeseed or peanut. The process that joins these two parts is called esterification, where heat and safe catalysts bond the glycerin chain to the fatty acid. This produces a waxy, plant-derived ingredient that is biodegradable and free of ethoxylation, which is why many formulators see it as a greener swap for older emulsifiers.
The cosmetic industry started turning to polyglyceryl esters in the early 2000s when brands wanted milder, more sustainable alternatives to traditional PEG-based emulsifiers. As testing showed that Polyglyceryl-6 Behenate could hold oil and water together without irritation, it quickly found a place in face creams, lotions, sunscreens, tinted moisturizers, lip balms, masks and baby care products. Its ability to boost stability while giving a soft, non-greasy feel keeps it popular in both mass and luxury ranges.
Polyglyceryl-6 Behenate’s Cosmetic Benefits/Uses
In skin care and makeup formulas Polyglyceryl-6 Behenate mainly works as an emulsion stabiliser. By anchoring oil droplets within the water phase it prevents creams or lotions from separating on the shelf or on the skin. This leads to a smoother texture, longer product life, consistent active delivery and a pleasant, velvety finish without the need for heavier waxes or high levels of synthetic surfactants.
Who Can Use Polyglyceryl-6 Behenate
Polyglyceryl-6 Behenate is generally well tolerated by all skin types, including sensitive, dry, oily and combination skin, because it is a mild emulsifier that does not add heavy oils or harsh surfactants to a formula. Its light, waxy structure sits comfortably on the skin without leaving a greasy film, making it suitable for acne-prone users as well.
The ingredient is sourced from plant-derived glycerin and behenic acid obtained from oils like rapeseed or peanut, so products containing it are typically appropriate for vegetarians and vegans. Always check the full ingredient list to confirm no animal-based additives have been included elsewhere in the formula.
Current safety data show no known reproductive or developmental risks, so Polyglyceryl-6 Behenate is considered safe for use during pregnancy and while breastfeeding. This is not medical advice and anyone who is pregnant or nursing should still clear any skincare routine with a healthcare professional to be extra cautious.
The ingredient does not make skin more sensitive to sunlight and has no reported impact on photosensitivity. It is also biodegradable and free of ethoxylation, which appeals to users seeking greener, low-irritation products.
Potential Side Effects/Adverse Reactions
Reactions to topical Polyglyceryl-6 Behenate differ from person to person. The points below outline possible side effects that could occur, but most people will not experience them when using a well-formulated product.
- Mild redness or stinging in very sensitive skin
- Allergic contact dermatitis in individuals with a specific fatty acid or peanut oil allergy
- Rare clogged pores or breakouts if used in an overly occlusive formula on highly acne-prone skin
If any irritation or adverse reaction develops discontinue use and consult a medical professional.
Comedogenic Rating
Rating: 1 / 5
Polyglyceryl-6 Behenate has a very low chance of clogging pores because its large molecular structure sits on the skin’s surface rather than seeping deep into follicles. It is derived from lightweight glycerin and a single fatty acid so it does not have the thick, oily feel often linked to breakouts. Most formulations use it at modest levels purely to stabilise emulsions, further lowering any pore clogging risk.
Overall this ingredient is considered suitable for acne-prone skin.
Formulas that pair Polyglyceryl-6 Behenate with heavy oils or waxes could still trigger congestion, so always look at the full ingredient list if you are highly breakout-prone.
Summary
Polyglyceryl-6 Behenate is mainly valued for keeping oil and water blended, extending product shelf life and giving creams a smooth, non greasy finish without harsh surfactants. It does this by anchoring oil droplets inside the water phase thanks to its dual glycerin-fatty acid structure.
The ingredient has gained steady popularity since the early 2000s among brands that want mild plant-based emulsifiers, and it now appears in everything from baby lotions to prestige sunscreens.
Safety data show it is low risk for irritation, non sensitising and biodegradable. Even so, skin can differ person to person so it is wise to perform a quick patch test when trying any new product that contains Polyglyceryl-6 Behenate.
