INCI: Poloxamer 124
Poloxamer 124 is a gentle synthetic ingredient that helps mix oil and water, making cleansers effective without stripping the skin.
In plain English
Poloxamer 124 is a man-made molecule that acts like a bridge between oil and water. In skincare, it helps cleansers remove dirt, makeup, and excess oil while rinsing away cleanly. It is considered very mild and is often used in products for sensitive skin because it cleans without leaving a greasy residue or causing irritation.

Quick decision guide
Useful, but context matters
Poloxamer 124 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 Poloxamer 124.
- 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 124 is a synthetic block copolymer made from ethylene oxide and propylene oxide. It belongs to the poloxamer family, known for their ability to act as surfactants (cleaning agents) and emulsifiers (mixing oil and water).
How it works
In a cosmetic product, Poloxamer 124 reduces the surface tension between oil and water, allowing them to blend into a stable mixture. When you rinse, it helps lift away oily impurities and dirt so they can be washed off easily. Its mildness comes from its large molecular structure, which is less likely to penetrate the skin barrier.
Pros
Very mild on skin
Poloxamer 124 is one of the gentlest surfactants, making it ideal for sensitive skin and daily cleansing without irritation.
Excellent rinsability
It rinses off completely, leaving no sticky or oily film behind, which helps maintain a clean, fresh feel.
Cons and cautions
Synthetic ingredient
It is not naturally derived, which may be a drawback for those seeking plant-based or natural skincare.
Potential for slight dryness at high levels
While generally mild, very high concentrations (above 10%) can sometimes cause mild dryness, especially on already dry skin.
Best for
- People with normal to sensitive skin looking for a mild cleanser
- Those who prefer non-soap, synthetic cleansers that are less alkaline
Use caution if
- Individuals with known allergies to polyethylene glycol (PEG) compounds (rare)
Usage tips
Safety summary
Poloxamer 124 is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been raised by regulatory bodies.
Research notes
Studies on poloxamers show they are well-tolerated on skin and eyes. The Cosmetic Ingredient Review (CIR) panel reviewed poloxamers and concluded they are safe as used in cosmetic formulations. Research continues on their use in drug delivery, but cosmetic safety is well-established.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, USA, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed poloxamers safe as used in cosmetics.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- Poloxamers are synthetic and not readily biodegradable, though they are considered low in toxicity to aquatic life at typical use levels.
Good to know
- Poloxamer 124 is also used in contact lens solutions and some medical formulations due to its low irritation profile
- It is often listed as Pluronic L44 on ingredient labels
