Ingredient review
Magnesium Palmitoyl Glutamate
INCI: Magnesium Palmitoyl Glutamate
A mild, amino-acid-based cleansing agent that effectively removes dirt and oil while helping skin feel soft and hydrated.
In plain English
This ingredient is a gentle cleanser made from palmitic acid (a fatty acid found in palm oil) and glutamic acid (an amino acid). It works by helping water and oil mix so that dirt and makeup can be rinsed away easily. Unlike harsh soaps, it is less likely to leave your skin feeling tight or dry, making it a popular choice for sensitive or dry skin types.

Quick decision guide
Useful, but context matters
Magnesium Palmitoyl Glutamate 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 Magnesium Palmitoyl Glutamate.
- 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
Magnesium Palmitoyl Glutamate is a surfactant and emulsifier derived from palmitic acid (a fatty acid from palm oil) and the amino acid glutamic acid, combined with magnesium. It is part of the amino-acid surfactant family, known for their mildness and skin-conditioning properties.
How it works
In a cosmetic product, this ingredient reduces the surface tension between water and oil, allowing them to mix. This helps lift dirt, excess oil, and makeup from the skin so they can be rinsed away. Its amino-acid structure also allows it to bind to the skin's surface, leaving a light conditioning film that helps maintain moisture.
Pros
Mild on skin
Its amino-acid base makes it much less irritating than traditional sulfate cleansers, so it won't strip your skin's natural moisture barrier.
Conditioning feel
It leaves a light, moisturizing film on the skin after rinsing, helping to prevent that tight, dry feeling many cleansers cause.
Cons and cautions
Palm oil source
Palmitic acid is often derived from palm oil, which can be linked to deforestation if not sustainably sourced. Look for RSPO-certified products if this matters to you.
Lower foam
It produces a creamy, low foam rather than big, bubbly lather. Some people prefer a richer foam for the sensory experience of cleansing.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone who prefers sulfate-free, amino-acid-based cleansing products
Use caution if
- Those seeking a very high-foaming, squeaky-clean feel may find it too mild
Usage tips
