Ingredient review
PPG-2 Dimethicone
INCI: PPG-2 Dimethicone
A gentle silicone that smooths skin and improves product feel without clogging pores.
In plain English
PPG-2 Dimethicone is a type of silicone that helps skincare products glide on smoothly and leaves skin feeling soft and silky. It forms a very light, breathable film on the skin that helps lock in moisture without feeling heavy or greasy. Unlike some heavier silicones, it is unlikely to clog pores or cause breakouts.

Quick decision guide
Useful, but context matters
PPG-2 Dimethicone 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-2 Dimethicone.
- 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-2 Dimethicone is a synthetic silicone polymer derived from dimethicone. It is a clear, odorless liquid that is used in cosmetics as an emollient and skin conditioner. The 'PPG-2' part refers to a short chain of propylene glycol units attached to the silicone backbone, which makes it more water-friendly and lighter than plain dimethicone.
How it works
When applied to the skin, PPG-2 Dimethicone spreads into a thin, even film that fills in fine lines and uneven texture, creating a smooth surface. This film also helps reduce water loss from the skin (transepidermal water loss, or TEWL) by acting as a gentle barrier. Because it is non-occlusive, it allows the skin to breathe while still providing a soft, velvety finish.
Pros
Lightweight feel
PPG-2 Dimethicone provides a silky, non-greasy finish that doesn't weigh down the skin, making it ideal for daytime use and under makeup.
Low irritation potential
It is generally very gentle and rarely causes stinging or redness, even for sensitive skin types.
Cons and cautions
Silicone buildup
If not removed thoroughly with a double cleanse or micellar water, it can accumulate on the skin over time, potentially leading to dullness or clogged pores for some users.
Not biodegradable
Like many silicones, PPG-2 Dimethicone is not readily biodegradable, which may be a concern for environmentally conscious consumers.
Best for
- People with normal to oily skin who want a lightweight, non-greasy feel
- Anyone looking for a smoothing primer or makeup base
Use caution if
- Those who prefer silicone-free or minimalist ingredient lists
Usage tips
Safety summary
PPG-2 Dimethicone is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic rating, making it suitable for most skin types. However, individuals with very sensitive or acne-prone skin should patch test first, as reactions are rare but possible.
Research notes
Research on PPG-2 Dimethicone is limited, but it is closely related to dimethicone, which has been extensively studied. The Cosmetic Ingredient Review (CIR) panel has deemed dimethicone and its derivatives safe for topical use. No significant toxicity or health concerns have been identified in cosmetic applications.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and the European Commission, with no concentration restrictions.
- Common uses
- Moisturizers, Serums, Primers, Sunscreens, Makeup foundations
- Environmental note
- PPG-2 Dimethicone is a synthetic silicone that is not readily biodegradable. Some manufacturers are moving toward more eco-friendly alternatives, but it remains widely used for its performance benefits.
Good to know
- PPG-2 Dimethicone is often used in combination with other silicones to fine-tune product feel.
- It is considered safe by major cosmetic safety panels when used as directed.
