What Is Dipentaerythrityl Hexaoctanoate/Hexabehenate?
Dipentaerythrityl Hexaoctanoate/Hexabehenate is a specialty ester created by combining a pentaerythritol dimer with six fatty acids, specifically octanoic and behenic acids. The result is a smooth wax-like substance that melts easily into oils and creams. It is synthesized through an esterification process where the fatty acids react with dipentaerythritol under controlled heat and vacuum, followed by purification to remove any unreacted materials. Chemists began exploring complex esters like this in the late 1990s as safer, plant-friendly options to replace heavier mineral oils and animal fats. Today manufacturers often derive the fatty acid portions from sustainable coconut, palm or rapeseed sources.
You will spot this ingredient in silky moisturizers, rich night creams, anti-aging serums, sunscreen lotions and creamy makeup such as foundations or BB creams. It is prized for giving formulas a plush feel without making them greasy, allowing brands to create products that glide on smoothly and leave a soft finish.
Dipentaerythrityl Hexaoctanoate/Hexabehenate’s Cosmetic Benefits/Uses
This multitasking ester brings a couple of key perks to personal care products:
- Skin conditioning: Forms a lightweight film that locks in water, leaving skin feeling soft, supple and comforted. It also helps reduce moisture loss throughout the day so the complexion looks fresh longer.
- Viscosity controlling: Adds body and thickness to creams and lotions so they feel rich and spread evenly. It also helps stabilize emulsions which keeps the formula from separating over time.
Who Can Use Dipentaerythrityl Hexaoctanoate/Hexabehenate
This silky ester is generally well tolerated by all skin types, including dry, normal, combination, oily and sensitive skin. It has a light texture that rarely feels heavy or greasy so even those who shy away from richer creams can usually use it comfortably. Extremely acne prone users may want to monitor how their skin responds, as any fatty ingredient has the potential to sit in pores if layered too thickly.
Because the raw materials are typically sourced from plants and no animal derivatives are involved, products that rely on this ester are considered suitable for vegans and vegetarians. Always check the full ingredient list though, since other components in the same product might not share this status.
Current safety data show no specific risks for pregnant or breastfeeding women when the ingredient is used as intended in cosmetic products. Still, this is not medical advice, and anyone who is expecting or nursing should run the formula past a healthcare professional just to be safe.
The ester does not increase sun sensitivity, so it will not make skin more prone to burning. It also plays nicely with common actives such as retinol, vitamin C and niacinamide and does not interfere with makeup wear time.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Dipentaerythrityl Hexaoctanoate/Hexabehenate vary from person to person. The issues listed below are possibilities only and are not expected for most users when the ingredient is properly formulated in a product.
- Mild redness or itching in very sensitive skin
- Rare allergic contact dermatitis if someone is specifically sensitized to the ester or residual fatty acids
- Clogged pores or small breakouts in individuals highly prone to comedones when used in heavy layers
- Temporary stinging if the product migrates into the eyes
If any of these reactions occur discontinue use and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 1/5
Although Dipentaerythrityl Hexaoctanoate/Hexabehenate is made from fatty acids its molecular structure is bulky and tends to sit on the surface rather than settling deep inside pores. This reduces the chance of the ingredient trapping oil and debris that could trigger blemishes. Most lab and user reports list it as low clogging compared with heavier plant butters or straight oils.
Suitable for acne-prone skin in most cases as long as the overall formula is light and applied sparingly.
If breakouts do appear they are usually linked to a high concentration of the ester or to other richer ingredients in the same product.
Summary
Dipentaerythrityl Hexaoctanoate/Hexabehenate conditions skin by forming a breathable film that slows water loss and leaves a smooth velvety finish. At the same time its waxy yet melt-in texture thickens creams and stabilizes emulsions so they stay uniform and easy to spread.
You will mainly see it in mid to high-end moisturizers sunscreens and color cosmetics but it is not as common as classics like glycerin or shea butter. Brands that want a lighter alternative to mineral oil or petrolatum often choose it.
Current safety assessments show a very low risk of irritation or systemic harm when used in cosmetics. Still skin is personal so try a small patch first whenever you pick up a new product containing this ester just to make sure it suits you.
