Ingredient review
PPG-7/Succinic Acid Copolymer
INCI: PPG-7/SUCCINIC ACID COPOLYMER
A gentle synthetic polymer that improves product feel and helps lock in moisture without clogging pores.
In plain English
This is a man-made ingredient that forms a thin, flexible film on your skin or hair. Think of it like a very lightweight, invisible glove that helps hold moisture in and keeps your hair in place without stiffness. It's commonly used in styling products and moisturizers to improve texture and longevity.

Quick decision guide
Useful, but context matters
PPG-7/Succinic Acid Copolymer is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging PPG-7/Succinic Acid Copolymer.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
PPG-7/Succinic Acid Copolymer is a synthetic polymer created by reacting propylene glycol (PPG) with succinic acid. It belongs to a class of ingredients called film formers, which means they create a continuous layer on the surface of skin or hair.
How it works
When applied, the copolymer spreads into a thin, even film that dries down to a flexible, non-sticky layer. This film helps reduce water loss from the skin (transepidermal water loss, or TEWL) and provides a smooth, silky feel. On hair, it helps hold styles and adds shine without making hair feel crunchy.
Pros
Gentle and non-irritating
This copolymer has a low irritation and comedogenic risk, making it suitable for sensitive skin types.
Flexible film for comfort
Unlike some stiff polymers, it creates a flexible layer that moves with your skin or hair, avoiding a tight or crunchy feel.
Cons and cautions
Synthetic origin
It is a lab-made ingredient, which may not align with preferences for natural or organic skincare routines.
Potential heaviness on oily skin
In high concentrations, the film could feel slightly heavy or occlusive for those with very oily skin.
Best for
- People with dry or dehydrated skin looking for extra moisture retention
- Anyone wanting a smooth, non-greasy finish in serums or moisturizers
- Those who use styling products and want flexible hold without stiffness
Use caution if
- Individuals with very oily or acne-prone skin may prefer lighter alternatives if they find film-formers too heavy
Usage tips
Safety summary
PPG-7/Succinic Acid Copolymer is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in regulatory reviews.
Research notes
While not extensively studied in isolation, succinic acid copolymers are part of a well-established class of film-forming ingredients with a long history of safe use in cosmetics. Their safety is supported by industry assessments and regulatory approvals.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions at typical use levels.
- Common uses
- Hair styling products, Leave-in conditioners, Serums, Moisturizers
- Environmental note
- As a synthetic polymer, its biodegradability depends on formulation and disposal conditions. Some studies suggest succinic acid-based copolymers may break down more readily than traditional acrylic polymers.
Good to know
- PPG-7/Succinic Acid Copolymer is often used in combination with other polymers to fine-tune texture and hold.
- It is considered biodegradable under certain conditions, though specific environmental data may vary by formulation.
