Poloxamine 1508
INCI: Poloxamine 1508
Poloxamine 1508 is a gentle synthetic ingredient that helps cleanse and stabilize formulas without stripping the skin.
In plain English
Poloxamine 1508 is a man-made molecule that acts like a bridge between oil and water. In skincare, it helps mix ingredients that normally don't blend, like oils and water, and it can also help cleanse the skin by trapping dirt and oil so they rinse away easily. It's known for being very gentle and not causing irritation, making it a good choice for sensitive skin products.

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 Poloxamine 1508.
- 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
Poloxamine 1508 is a synthetic block copolymer, meaning it's a large molecule made of repeating units of ethylene oxide and propylene oxide. It belongs to the poloxamine family, which are non-ionic surfactants known for their mildness and versatility.
How it works
In a cosmetic product, Poloxamine 1508 works by reducing the surface tension between oil and water, allowing them to mix into a stable emulsion. As a surfactant, it also helps lift dirt, oil, and makeup from the skin so they can be rinsed away. Its large molecular structure makes it less likely to penetrate the skin, which contributes to its low irritation potential.
Pros
Very gentle on skin
Poloxamine 1508 has a low irritation risk, making it ideal for sensitive skin types and daily use without causing dryness or redness.
Effective emulsifier
It helps blend oil and water smoothly, improving the texture and stability of creams, lotions, and cleansers.
Cons and cautions
Synthetic ingredient
It is man-made, which may be a drawback for consumers who prefer natural or organic skincare products.
Limited natural appeal
Because it's not derived from plants, it may not align with 'clean beauty' trends, even though it is safe and mild.
Best for
- People with sensitive or reactive skin
- Anyone looking for a gentle, non-stripping cleanser
Use caution if
- Those seeking 100% natural or organic formulations
Usage tips
Safety summary
Poloxamine 1508 is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in available studies.
Research notes
Research on poloxamines, including Poloxamine 1508, indicates they are mild surfactants with good emulsifying properties. Studies show low acute toxicity and skin irritation. However, long-term human exposure data is limited, and most evidence comes from industrial and pharmaceutical applications.
Common label clues
- Typical concentration
- 0.5% to 5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. It is generally recognized as safe when used as directed.
- Common uses
- Cleansers, Shampoos, Body washes, Lotions, Serums
- Environmental note
- Poloxamine 1508 is biodegradable, but as a synthetic compound, its production relies on petrochemicals. It is not derived from renewable resources.
Good to know
- Poloxamine 1508 is often used in baby shampoos because of its gentle nature
- It is biodegradable and considered environmentally friendly compared to some other synthetic surfactants
