What Is Dimethicone/Vinyl Dimethicone/Polyglyceryl-10 Heptaoleate Crosspolymer?
Dimethicone/Vinyl Dimethicone/Polyglyceryl-10 Heptaoleate Crosspolymer is a specialty silicone made by linking together three building blocks: dimethicone, vinyl dimethicone and polyglyceryl-10 heptaoleate. Dimethicone and vinyl dimethicone are smooth, flexible silicones that come from silica found in sand, while polyglyceryl-10 heptaoleate is a plant-derived ester created by joining glycerin with oleic acid from natural oils. Chemists combine these materials in a controlled process called crosslinking, turning the liquid ingredients into a soft solid network that disperses easily in oils or emulsions. Silicone chemistries like this began appearing in cosmetics in the late 1990s when brands wanted lighter textures and longer wear; formulators soon discovered that adding a plant-based polyglyceryl piece improved spreadability and skin feel. Today this crosspolymer shows up in many product types, including primers, liquid and powder foundations, tinted moisturizers, setting sprays, BB and CC creams, daily sunscreens, leave-on hair serums, sheet masks and rich facial creams that aim to give a silky finish.
Dimethicone/Vinyl Dimethicone/Polyglyceryl-10 Heptaoleate Crosspolymer’s Cosmetic Benefits/Uses
This ingredient offers one main action that gives formulas their signature smooth feel and long-lasting finish.
Film forming: When spread over skin or hair the crosspolymer sets into an invisible flexible layer that locks in moisture, blurs fine lines, boosts water resistance and helps makeup stay put. Because the film is breathable and non-sticky it leaves a soft, velvety touch that many people associate with high-end cosmetics.
Who Can Use Dimethicone/Vinyl Dimethicone/Polyglyceryl-10 Heptaoleate Crosspolymer
This crosslinked silicone suits most skin types including dry, normal, combination, oily and even sensitive skins because it forms a lightweight breathable film that does not pull water from the skin or leave a greasy residue. Extremely acne-prone users who react to any occlusive layer may still prefer to avoid heavy silicone films, though the ingredient itself is widely regarded as low risk for clogged pores.
The raw materials come from mineral and plant sources and contain no animal derivatives, so finished products using this polymer are generally acceptable for both vegetarians and vegans provided the rest of the formula also meets their standards.
Absorption through skin is negligible and there are no published reproductive toxicity concerns, so products with this ingredient are considered safe for pregnant or breastfeeding women. This is not medical advice and anyone expecting or nursing should confirm product choices with a qualified healthcare professional.
The molecule does not make skin more sensitive to sunlight, so it does not raise any photosensitivity issues. It can be layered with common actives like retinoids, vitamin C or exfoliating acids without known incompatibilities.
Potential Side Effects/Adverse Reactions
Reactions to topical Dimethicone/Vinyl Dimethicone/Polyglyceryl-10 Heptaoleate Crosspolymer vary from person to person. The effects listed below are possible but uncommon when the ingredient is used at normal cosmetic levels and manufactured correctly.
- Contact irritation or redness in very sensitive individuals
- Acne-like breakouts in users already prone to congestion
- Mild eye stinging if product migrates into the eyes before it sets
- Buildup on hair shafts leading to dullness when used in leave-on hair products without periodic clarifying
- Enhanced potency of strong actives trapped under the film, potentially amplifying irritation from those actives
If any discomfort, rash or persistent breakout develops, stop using the product and consult a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1/5 – The crosslinked structure creates a large, inert molecule that stays on the surface and does not readily sink into pores, so it is unlikely to clog them. Most clinical and anecdotal reports show very few breakout issues when it is used at typical levels. Because it still forms a breathable film, people who are highly prone to congestion can usually tolerate it, but very oily skins layered under heavy makeup may notice occasional build-up. Overall it is considered suitable for acne-prone users.
Extra note: formulas that pair this polymer with heavier waxes or butters can raise the combined comedogenic potential, so pore-clogging risk depends on the full ingredient list, not this silicone alone.
Summary
Dimethicone/Vinyl Dimethicone/Polyglyceryl-10 Heptaoleate Crosspolymer is a film-forming silicone that glides on then sets into a flexible veil, locking in hydration, improving spreadability, blurring fine lines and boosting makeup wear time. Its hybrid of classic dimethicone and plant-based polyglyceryl ester gives products a lightweight, velvety finish without greasy afterfeel.
The polymer enjoys steady popularity in primers, liquid foundations, sunscreens and hair serums where consumers expect a smooth touch and long-lasting performance, though it is less common than standard dimethicone because it costs more and requires specific processing.
Regulatory panels and published data rate it as low-risk for irritation, sensitization and systemic absorption, making it safe for regular cosmetic use. As with any new product it is wise to patch test first to make sure your individual skin agrees with the full formula.
