Ingredient review
PPG-15 Stearate
INCI: PPG-15 Stearate
A gentle synthetic emollient that helps products feel smooth and spread easily without clogging pores.
In plain English
PPG-15 Stearate is a man-made ingredient that softens and smooths the skin. It works by forming a light, non-greasy film that helps other ingredients spread evenly and makes the product feel silky. It is often used in moisturizers and cleansers to improve texture without leaving a heavy residue.

Quick decision guide
Useful, but context matters
PPG-15 Stearate 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-15 Stearate.
- 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-15 Stearate is a synthetic polymer made by combining propylene glycol (a humectant) with stearic acid (a fatty acid). It acts as an emollient and skin conditioner.
How it works
It sits on the skin's surface, reducing friction and helping the product glide on. It also helps stabilize emulsions, keeping oil and water mixed together for a consistent texture.
Pros
Lightweight feel
Provides a silky, non-greasy texture that absorbs quickly, making it ideal for daytime moisturizers.
Low pore-clogging risk
Rated low on the comedogenic scale, so it's unlikely to cause breakouts for most skin types.
Cons and cautions
Synthetic origin
Not plant-derived or natural, which may be a drawback for consumers seeking clean or green beauty products.
Limited research
Few independent studies exist on its long-term skin effects, though it is generally considered safe by regulators.
Best for
- People with normal to dry skin looking for a lightweight emollient
- Those who prefer non-comedogenic ingredients
Use caution if
- Individuals strictly avoiding synthetic ingredients
- Those with known sensitivity to propylene glycol derivatives
Usage tips
Safety summary
PPG-15 Stearate is considered safe for topical use in cosmetics. It has low irritation and sensitization potential, and is not known to be toxic at typical concentrations.
Research notes
Safety assessments by the CIR panel and other regulatory bodies support its use. No significant adverse effects have been reported in human patch tests or animal studies at cosmetic levels.
