Quick decision guide
Useful, but context matters
Octyldodecyl Bis-Hydroxypropyl Dimethicone Citrate Crosspolymer 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 Octyldodecyl Bis-Hydroxypropyl Dimethicone Citrate Crosspolymer.
- 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 modified with citrate (a derivative of citric acid) and a fatty alcohol (octyldodecanol). It is a crosspolymer, meaning its molecules are linked together to create a stable, film-forming structure.
How it works
When applied, it leaves a lightweight, breathable film on the skin's surface. This film smooths the skin, reduces water loss, and helps other ingredients spread evenly. It also gives a soft, velvety feel and can improve the wear time of makeup.
Pros
Silky, non-greasy feel
Leaves a velvety finish that reduces friction, making it ideal for primers and sunscreens.
Improves product wear
Forms a flexible film that helps makeup and SPF stay put longer without feeling heavy.
Cons and cautions
Synthetic origin
Made from petrochemicals, which may not align with natural or minimalist skincare preferences.
Potential heaviness on oily skin
In high concentrations, it can feel slightly occlusive for those with very oily or acne-prone skin.
Best for
- Anyone looking for a smooth, silky finish in moisturizers or makeup
- People with normal to dry skin who want extra slip and spreadability
Use caution if
- Those who strictly avoid silicones in their skincare routine
Usage tips
Safety summary
Considered safe for topical use in cosmetics. Low irritation and comedogenic risk. Not absorbed into the skin. Some consumers avoid silicones for personal or environmental reasons.
Research notes
Limited independent studies specific to this polymer, but silicone crosspolymers in general are well-tolerated and widely used. Safety assessments by cosmetic ingredient review panels support their use at typical concentrations.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (US) and EU CosIng database, with no known restrictions.
- Common uses
- Moisturizers, Sunscreens, Primers, Foundations
- Environmental note
- As a silicone derivative, it may not be biodegradable. However, its high molecular weight reduces absorption and environmental persistence concerns compared to smaller silicones.
Good to know
- This ingredient is often used in 'silicone-based' primers and long-wear foundations.
- It is considered non-comedogenic and safe for sensitive skin.
