PEG/PPG-12/35 Copolymer

INCI: PEG/PPG-12/35 Copolymer

A gentle synthetic polymer that helps products feel silky and spread evenly without clogging pores.

In plain English

PEG/PPG-12/35 Copolymer is a man-made ingredient that helps skincare products glide on smoothly and feel lightweight. It also holds a bit of moisture on the skin, which can make your face feel softer. Because it's a polymer (a long chain of molecules), it forms a very thin, breathable film that doesn't feel heavy or sticky.

Quick decision guide

Useful, but context matters

PEG/PPG-12/35 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging PEG/PPG-12/35 Copolymer.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic copolymer made from ethylene oxide and propylene oxide chains, designed to improve product texture and water-binding ability.

How it works

It sits on the skin's surface, forming a flexible film that reduces water loss and helps other ingredients spread evenly. Its humectant properties also attract a small amount of moisture from the air.

Pros

Silky texture

Creates a smooth, velvety feel on skin without heavy oils, making it ideal for lightweight serums and moisturizers.

Low irritation

Rated very low on irritation and comedogenic scales, so it's generally safe for sensitive and acne-prone skin.

Cons and cautions

Synthetic origin

Made from petrochemicals, which may be a concern for those seeking fully natural or biodegradable formulas.

Potential tackiness

At higher concentrations, it can leave a slightly sticky or tacky residue, especially in humid conditions.

Best for

  • People with normal to dry skin wanting lightweight hydration
  • Anyone who prefers non-greasy, fast-absorbing textures

Use caution if

  • Those strictly avoiding all synthetic ingredients
  • Individuals with known sensitivity to PEG compounds (rare)

Usage tips

Apply on damp skin to enhance the humectant effect and reduce any tackiness.
Layer with a richer moisturizer if you have very dry skin, as this polymer alone is not a heavy occlusive.

Safety summary

Considered safe for topical use in cosmetics. PEG compounds have been scrutinized for potential contamination with 1,4-dioxane during manufacturing, but cosmetic-grade PEGs are purified to meet safety standards. The risk is negligible in properly formulated products.

Research notes

Limited independent studies on this specific copolymer, but the broader class of PEG/PPG polymers is well-documented for low skin irritation and effective film-forming properties. Safety assessments by the Cosmetic Ingredient Review (CIR) support its use.

Common label clues

Typical concentration
0.5–5% in leave-on products
Regulatory status
Approved for cosmetic use globally, including by the FDA and EU CosIng database, with no known restrictions at typical use levels.
Common uses
Serums, Moisturizers, Sunscreens, Makeup
Environmental note
As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is not considered a major environmental concern compared to microplastics.

Good to know

  • PEG/PPG copolymers are common in many drugstore and prestige brands due to their versatility.
  • They are often used in sunscreens to improve water resistance and even application.
