What Is Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer?
Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer is a man-made ingredient created by linking together sorbitol that has been reacted with a small amount of ethylene oxide, the natural fatty acid oleic acid, and dilinoleic acid, which is another fatty material often sourced from vegetable oils. When these pieces are chemically joined they form a flexible network, or polymer, that stays stable in cosmetic formulas.
The idea of using sorbitol-based polymers in skincare took off in the late 20th century as chemists searched for gentle, plant-derived options to soften and smooth skin. By crosslinking the fatty acids with sorbeth-2, formulators were able to craft a molecule that behaves like a lightweight oil yet holds its shape and does not feel greasy.
Production starts with food-grade sorbitol, usually made from corn syrup. It is lightly treated with ethylene oxide to create sorbeth-2, giving it a mild water-loving nature. This is then reacted with oleic and dilinoleic acids under heat and a catalyst, forming long chains that lock together. The result is a creamy, semi-solid substance that blends easily into both water-based and oil-based mixes.
You will most often see Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer in moisturizers, nourishing masks, anti-aging serums, tinted creams, balm cleansers, and rich body butters where a smooth, cushiony after-feel is desired. It is also used in lip products to give a soft glide and in sunscreens to keep the formula uniform.
Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer’s Cosmetic Benefits/Uses
This ingredient serves a couple of key roles that improve how a product feels and performs on skin.
- Skin Conditioning: Forms a light, breathable film that leaves skin feeling silky and hydrated. It helps reduce roughness so the complexion looks smoother and more supple
- Emollient: Fills in tiny gaps between skin cells, creating a soft surface and locking in moisture. This makes creams spread more easily and enhances overall comfort during wear
This ingredient is generally well tolerated by most skin types, including normal, dry, combination and mature skin. Its lightweight emollient nature makes it a good fit for oily and acne-prone skin too, as it softens without leaving a heavy residue. Extremely sensitive or allergy-prone users should check the full formula for additional triggers, but the polymer itself is considered low risk.
Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer is made from plant-derived sorbitol and vegetable oils, so it is suitable for vegans and vegetarians. No animal-sourced raw materials or by-products are involved in its manufacture.
Available safety data show no specific concerns for pregnant or breastfeeding women when this ingredient is applied topically. Still, this is not medical advice and anyone who is expecting or nursing should review any skincare routine with a healthcare professional to be extra safe.
The polymer does not make skin more sensitive to sunlight, so there is no added risk of photosensitivity. It also plays nicely with common actives like vitamin C, niacinamide and retinoids, making it a versatile choice in layered routines.
Potential Side Effects/Adverse Reactions
Responses to topical Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer can vary from person to person. The points below list potential side effects, though they are uncommon when the ingredient is used correctly in a finished product.
- Mild redness or irritation
- Temporary stinging on very compromised or freshly exfoliated skin
- Rare allergic contact dermatitis for individuals sensitive to sorbitol derivatives
If any of these reactions occur stop using the product and consult a medical professional if symptoms persist.
Comedogenic Rating
Rating: 1 / 5
The molecule is large and crosslinked, so it tends to remain on the surface instead of collecting inside pores. It delivers a light, dry finish and is usually added at low to moderate levels, which keeps the risk of clogging minimal.
Generally considered suitable for acne-prone or breakout-prone skin.
If the formula also contains rich butters or waxes overall pore-clogging potential will depend on those companions, not this polymer alone.
Summary
Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer works as a skin conditioner and emollient. It lays down a thin breathable layer that smooths rough spots, seals in water and helps products spread with a cushiony slip.
While not as famous as hyaluronic acid or glycerin it is quietly gaining popularity in creams, masks, lip balms and tinted products where a velvety feel is prized.
Current research shows it is low risk for irritation making it safe for most users. Still, it is smart to perform a quick patch test whenever trying a new product that features this ingredient just to be sure your skin stays happy.
