PPG-36 Oleate

INCI: PPG-36 OLEATE

PPG-36 Oleate is a synthetic emollient that helps products glide on smoothly, but it may be moderately comedogenic for acne-prone skin.

In plain English

PPG-36 Oleate is a man-made oil-like ingredient used in skincare and cosmetics to make products feel silky and spread easily. It's a type of polymer (a long chain molecule) combined with a fatty acid from olive oil. While it helps moisturize by forming a light film on the skin, it can sometimes clog pores in people who are prone to breakouts.

Quick decision guide

Useful, but context matters

PPG-36 Oleate can be useful, but watch for possible clogging concerns.

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 PPG-36 Oleate.
  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

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

moderate

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

What it is

PPG-36 Oleate is a synthetic ester created by reacting polypropylene glycol (a polymer) with oleic acid (a fatty acid found in olive oil). It functions as an emollient and emulsifier, helping to soften skin and stabilize mixtures of oil and water.

How it works

In a cosmetic product, PPG-36 Oleate sits on the skin's surface, reducing water loss by forming a thin, non-greasy barrier. As an emulsifier, it helps blend oil and water ingredients so the product stays uniform and applies smoothly.

Pros

Smooth texture

PPG-36 Oleate gives products a silky, non-sticky feel, making them pleasant to apply and wear.

Effective emulsifier

It helps keep oil and water mixed in creams and lotions, preventing separation and ensuring consistent performance.

Cons and cautions

Moderate comedogenic risk

This ingredient can clog pores for some people, especially those with acne-prone skin, potentially leading to breakouts.

Synthetic origin

As a man-made polymer, it may not be preferred by consumers seeking natural or plant-based skincare options.

Best for

  • People with normal to dry skin looking for a lightweight emollient
  • Those who use makeup removers or cleansing balms and want a smooth texture

Use caution if

  • Individuals with acne-prone or very oily skin who are sensitive to pore-clogging ingredients

Usage tips

If you have acne-prone skin, patch test products containing PPG-36 Oleate before full-face use.
Use in rinse-off products like cleansers to minimize prolonged contact with the skin.

Safety summary

PPG-36 Oleate is considered safe for use in cosmetics at typical concentrations. It has low irritation potential, but its moderate comedogenic risk means it may not suit everyone, particularly those with acne-prone skin.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found PPG derivatives to be safe in cosmetics. Comedogenicity data is limited but anecdotal reports suggest moderate pore-clogging potential.

Common label clues

Typical concentration
Typically 1–10% in leave-on products, up to 20% in rinse-off products
Regulatory status
Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no known restrictions at typical concentrations.
Common uses
Moisturizers, Cleansers, Makeup removers, Hair conditioners
Environmental note
As a synthetic polymer, PPG-36 Oleate may not be biodegradable, but it is not classified as a microplastic due to its solubility.

Good to know

  • PPG-36 Oleate is often used in makeup removers because it helps dissolve waterproof makeup without heavy oils.
  • The '36' refers to the number of propylene glycol units in the polymer chain, which affects its thickness and feel.
