Ingredient review
Cycloethoxymethicone
INCI: Cycloethoxymethicone
A gentle silicone that improves product feel and spreadability with a low risk of irritation or clogged pores.
In plain English
Cycloethoxymethicone is a type of silicone that feels very light and silky on the skin. It helps creams and serums glide on smoothly without leaving a greasy or sticky finish. Because it evaporates slightly after application, it can also give a soft, powdery feel. It is considered very gentle and unlikely to cause breakouts or irritation for most people.

Quick decision guide
Useful, but context matters
Cycloethoxymethicone 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 Cycloethoxymethicone.
- 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
A synthetic silicone polymer designed to provide a smooth, non-greasy feel and improve the texture of cosmetic products.
How it works
It forms a thin, breathable film on the skin that reduces friction, allowing products to spread evenly. It also helps other ingredients like pigments or active compounds distribute more uniformly.
Pros
Lightweight feel
It provides a silky, non-greasy texture that many people find pleasant, especially for daytime use under makeup.
Low irritation risk
Cycloethoxymethicone is considered very gentle and unlikely to cause stinging, redness, or allergic reactions, making it suitable for sensitive skin.
Cons and cautions
Silicone avoidance
Some people choose to avoid silicones for personal or environmental reasons, and this ingredient is a synthetic silicone.
Potential buildup
If used in large amounts or without proper cleansing, it can accumulate on the skin or hair, potentially leading to a dull appearance over time.
Best for
- People who prefer lightweight, non-greasy moisturizers
- Those with normal to oily skin looking for a smooth finish
Use caution if
- Individuals who deliberately avoid silicones in their routine
- Those with very dry skin who may prefer richer emollients
Usage tips
Safety summary
Cycloethoxymethicone is considered safe for use in cosmetics at typical concentrations. It has low skin irritation and comedogenic potential. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on this specific silicone is limited, but it is structurally similar to other well-studied cyclic silicones that are considered safe. The Cosmetic Ingredient Review (CIR) panel has reviewed related silicones and found them safe as used.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Primers, Sunscreens, Makeup foundations
- Environmental note
- Like many silicones, it may not be readily biodegradable. Some consumers choose silicone-free alternatives for environmental reasons.
Good to know
- Cycloethoxymethicone is a cyclic silicone, similar to cyclomethicone, but with an added ethoxy group that may alter its volatility and feel.
- It is often used in combination with other silicones to fine-tune product texture.
