Meroxapol 174
INCI: Meroxapol 174
A mild synthetic surfactant that helps blend oil and water in cleansers, generally well-tolerated but not a standout active ingredient.
In plain English
Meroxapol 174 is a man-made ingredient that helps oil and water mix together in products like face washes and shampoos. It creates a gentle lather and helps remove dirt and oil without stripping the skin. Think of it as a helper that keeps the formula stable and easy to rinse off.

Quick decision guide
Useful, but context matters
Meroxapol 174 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 Meroxapol 174.
- 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
Meroxapol 174 is a synthetic block copolymer, part of the poloxamer family, designed to act as a surfactant and emulsifier in cosmetic formulations.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable mixture. This helps cleansers lift dirt and oil from the skin and rinse away cleanly without leaving a heavy residue.
Pros
Gentle cleanser
Meroxapol 174 cleans without stripping the skin's natural moisture barrier, making it suitable for daily use.
Stable formula
It helps keep oil and water mixed, preventing separation and ensuring a consistent product texture.
Cons and cautions
Synthetic origin
It is not derived from natural sources, which may be a drawback for consumers seeking plant-based ingredients.
Limited standout benefits
It functions primarily as a formulation aid rather than providing active skincare benefits like hydration or anti-aging.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Those who prefer synthetic but mild surfactants
Use caution if
- Individuals seeking 100% natural or organic formulations
- Those with known sensitivity to poloxamers (rare)
Usage tips
Safety summary
Meroxapol 174 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with very sensitive skin should patch-test new products.
Research notes
Research on poloxamers supports their safety as surfactants. However, specific studies on Meroxapol 174 are limited, with most data coming from the broader poloxamer family.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- As a synthetic polymer, it may not be biodegradable, but it is used in low concentrations and is generally considered low-risk for aquatic environments.
Good to know
- Meroxapol 174 is part of a larger family of poloxamers, which vary in their properties based on molecular weight.
- It is often used in combination with other surfactants to fine-tune lather and mildness.
