Ingredient review
Poloxamer 182
INCI: Poloxamer 182
Poloxamer 182 is a gentle synthetic surfactant that helps cleanse without stripping the skin's natural moisture barrier.
In plain English
Poloxamer 182 is a man-made ingredient that helps water and oil mix together in products like cleansers and shampoos. It works by reducing the surface tension between oil and water, allowing them to blend and rinse away dirt, makeup, and excess oil. Because it is mild and non-irritating, it is often used in gentle cleansing formulas.

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 Poloxamer 182.
- 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
Poloxamer 182 is a synthetic block copolymer made from ethylene oxide and propylene oxide. It belongs to the poloxamer family of non-ionic surfactants, known for their mildness and ability to emulsify oils.
How it works
In a cosmetic product, Poloxamer 182 acts as a surfactant and emulsifier. It surrounds oil droplets, allowing them to be suspended in water so they can be rinsed away. It also helps stabilize formulations that contain both water and oil phases, preventing separation.
Pros
Mild on skin
Poloxamer 182 is known for low irritation potential, making it suitable for sensitive skin types when used in appropriate concentrations.
Effective emulsifier
It helps blend oil and water, improving the texture and stability of cleansers and makeup removers without harshness.
Cons and cautions
Synthetic ingredient
As a synthetic polymer, it may not appeal to consumers seeking natural or plant-based skincare ingredients.
Potential for dryness at high levels
In very high concentrations, it can slightly disrupt the skin's natural oils, though this is rare in well-formulated products.
Best for
- People with normal to oily skin looking for a mild cleanser
- Those who prefer fragrance-free or low-irritation products
Use caution if
- Individuals with extremely dry or compromised skin barriers who may need even gentler cleansing options
Usage tips
Safety summary
Poloxamer 182 is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and is not known to be comedogenic. Regulatory bodies like the CIR have reviewed it favorably.
Research notes
Studies on poloxamers indicate they are mild surfactants with low toxicity. Research supports their use in gentle cleansing products, though individual formulations should always be patch-tested.
Common label clues
- Typical concentration
- 1% to 10% depending on formulation
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed poloxamers safe as used in cosmetics.
