What Is Ppg-7/Succinic Acid Copolymer?
Ppg-7/Succinic Acid Copolymer is a synthetic polymer created by linking propylene glycol (specifically Ppg-7) with succinic acid, a naturally occurring dicarboxylic acid. The result is a chain-like molecule that carries both water-loving and oil-loving parts, giving it useful surface-coating abilities. Chemists first explored this type of copolymer in the late twentieth century while looking for lightweight alternatives to heavier resins used in hair sprays and skin treatments. Today manufacturers produce it through controlled condensation: propylene oxide is polymerized to form Ppg-7, then reacted with succinic acid under heat and vacuum, producing a smooth, pourable resin once the water formed in the reaction is removed.
You will most often see Ppg-7/Succinic Acid Copolymer in leave-in and rinse-off hair products such as sprays, mousses and conditioners. It also appears in some facial primers, long-wear makeup, lightweight moisturizers and sunscreen films where a breathable protective layer is needed.
Ppg-7/Succinic Acid Copolymer’s Cosmetic Benefits/Uses
This ingredient pulls its weight in formulas by improving how products look, feel and last on hair or skin.
- Film forming: It spreads into a thin uniform layer that dries into a flexible film. This film helps lock in moisture, boosts product durability and gives makeup or sunscreen better resistance against sweat and rubbing
- Hair conditioning: The polymer smooths the hair shaft making strands easier to comb, adding light softness without heaviness and reducing static for a sleeker finish
Who Can Use Ppg-7/Succinic Acid Copolymer
Ppg-7/Succinic Acid Copolymer is generally well tolerated by all skin types including oily, dry and combination skin thanks to its lightweight non-greasy film. Sensitive skin usually handles it without issues, though anyone with a known sensitivity to synthetic polymers should proceed carefully. Because the ingredient is fully synthetic and contains no animal derivatives it is considered suitable for both vegans and vegetarians.
Current safety data show no specific hazards for pregnant or breastfeeding women when the ingredient is used topically in normal cosmetic concentrations. That said this information is not medical advice and anyone who is pregnant or nursing should have a doctor review their personal care routine to be safe.
The polymer does not cause photosensitivity so it will not make skin more prone to sunburn. It is also color safe for treated hair and rinses out easily without leaving heavy buildup when used as directed.
Potential Side Effects/Adverse Reactions
Individual reactions to topical Ppg-7/Succinic Acid Copolymer can vary. The effects listed below are only potential outcomes and are unlikely for most users when the ingredient is properly formulated.
- Mild skin irritation such as slight redness or itching, usually in people with very reactive skin
- Contact dermatitis in rare cases where an allergy to the polymer or other formula components exists
- Temporary buildup on hair leading to a weighed-down feel if products containing high concentrations are not washed out regularly
- Eye irritation if the product accidentally gets into the eyes during application
If any of these effects occur stop using the product and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1/5 (very low). Ppg-7/Succinic Acid Copolymer is a lightweight water-dispersible polymer that does not leave an occlusive oily residue on skin. Its molecules are too large to slip into pores and it rinses away easily, so it has little tendency to trap sebum or dead cells that could spark breakouts. For most acne-prone individuals this ingredient is considered safe to use. Because it can be paired with heavier waxes or oils in certain formulas, overall pore-clogging risk depends on the full product, not the polymer itself.
Summary
Ppg-7/Succinic Acid Copolymer mainly acts as a film former and hair conditioner. It flows into a thin uniform layer that dries into a flexible breathable film, helping products stay put, resist rubbing and hold moisture. On hair the same film smooths the cuticle so strands feel softer, tangle less and carry less static without weighing styles down.
While not the most talked-about ingredient it appears steadily in modern lightweight sprays, leave-ins and long-wear makeup where its subtle performance shines. Current safety reviews show it is low risk for irritation or comedogenicity when used in normal cosmetic levels. Still, everyone’s skin is different so it is smart to patch test any new product featuring this polymer to be sure it works well for you.
