PEG/PPG-240/60 Copolymer

INCI: PEG/PPG-240/60 COPOLYMER

A safe, synthetic thickener that gives water-based products a silky, non-sticky feel, but offers no active skin benefits.

In plain English

PEG/PPG-240/60 Copolymer is a large synthetic molecule added to skincare and haircare to make the product feel thicker, smoother, and more spreadable. It doesn't actively treat the skin—it's more like a texture helper that prevents watery formulas from running off your face. Because it's a polymer, it can also form a very light, invisible film that helps other ingredients stay put. It's considered very gentle and unlikely to clog pores or cause irritation.

Quick decision guide

Useful, but context matters

PEG/PPG-240/60 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-240/60 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 repeating units of ethylene oxide (PEG) and propylene oxide (PPG), resulting in a very large molecule that dissolves in water and acts as a thickener and film former.

How it works

When added to water, the long polymer chains entangle and increase the viscosity of the formula, creating a gel-like consistency. Upon application, the water evaporates and the polymer leaves a thin, flexible film on the skin or hair, which can improve the feel and longevity of the product.

Pros

Excellent texture enhancer

Provides a silky, non-tacky feel that makes water-based products pleasant to apply and layer under makeup or sunscreen.

Very low irritation risk

Large polymer molecules are too big to penetrate the skin, so they sit on the surface and rarely cause stinging, redness, or allergic reactions.

Cons and cautions

No active skin benefits

This ingredient only improves product feel and stability—it doesn't hydrate, exfoliate, or deliver any nutrients to the skin.

Synthetic and non-biodegradable

As a synthetic polymer, it may not break down easily in the environment, which is a concern for eco-conscious consumers.

Best for

  • Anyone who prefers lightweight, non-sticky gel or serum textures
  • People with oily or combination skin who want hydration without heaviness

Use caution if

  • Those seeking only natural or plant-derived ingredients
  • Individuals with very sensitive skin who react to many synthetic polymers (rare)

Usage tips

Look for this ingredient in gel-based moisturizers and serums if you dislike heavy creams.
Layer products containing this polymer from thinnest to thickest to avoid pilling.

Safety summary

PEG/PPG-240/60 Copolymer is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and the large molecular size prevents skin penetration. Regulatory bodies like the CIR have deemed it safe at typical use levels.

Research notes

Safety assessments focus on the broader class of PEG/PPG copolymers. The Cosmetic Ingredient Review (CIR) has reviewed similar polymers and found them safe for cosmetic use. No specific clinical studies on this exact copolymer were identified, but its chemical class is well-established as low-risk.

Common label clues

Typical concentration
0.1% to 2%
Regulatory status
Approved for use in cosmetics globally; reviewed by the Cosmetic Ingredient Review (CIR) panel and considered safe at typical concentrations.
Common uses
Serums, Gels, Moisturizers, Hair Styling Products, Masks
Environmental note
As a synthetic polymer, it is not readily biodegradable. However, it is used in low concentrations and is not classified as a microplastic due to its water solubility.

Good to know

  • PEG/PPG copolymers are common in cosmetics and have been reviewed by safety panels as safe for topical use.
  • The numbers 240/60 refer to the average number of repeating units in the polymer chain, which determines its thickness and film-forming properties.
