Ingredient review
Glyceryl Stearate Citrate
INCI: Glyceryl Stearate Citrate
A mild, plant-derived emulsifier that helps create stable, creamy textures without common irritation.
In plain English
Glyceryl Stearate Citrate is an ingredient that helps oil and water mix together in creams and lotions. It's made from glycerin (a natural moisturizer), stearic acid (a fatty acid from plants or animals), and citric acid (found in citrus fruits). This combination creates a gentle emulsifier that gives products a smooth, creamy feel without being harsh on the skin. It's often used in 'natural' or 'gentle' formulations because it's considered milder than some traditional emulsifiers.

Quick decision guide
Easy yes for most routines
Glyceryl Stearate Citrate 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 Glyceryl Stearate Citrate.
- 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
A semi-synthetic emulsifier created by combining glycerin, stearic acid (a fatty acid), and citric acid. It is commonly used in cosmetics to stabilize oil-in-water emulsions, meaning it helps tiny oil droplets stay evenly dispersed in water, preventing separation.
How it works
When you mix oil and water, they naturally separate. Glyceryl Stearate Citrate has a water-loving head and an oil-loving tail, so it positions itself at the boundary between oil and water droplets. This reduces surface tension and keeps the mixture stable, resulting in a uniform, creamy product that feels smooth when applied to the skin.
Pros
Gentle on skin
Glyceryl Stearate Citrate is known for its low irritation potential, making it a good choice for sensitive skin formulations.
Improves product texture
It helps create a smooth, creamy consistency that feels pleasant and non-greasy on the skin.
Cons and cautions
Semi-synthetic origin
While derived from natural sources, it undergoes chemical processing, which may not appeal to those seeking 100% natural ingredients.
Limited compatibility
It may not work well with all oil types or in very high-oil formulations, potentially requiring additional stabilizers.
Best for
- People with normal to dry skin looking for a gentle moisturizer
- Those with sensitive or reactive skin who want to avoid harsh emulsifiers
Use caution if
- Individuals with a known allergy to any of its components (glycerin, stearic acid, citric acid)
Usage tips
Safety summary
Glyceryl Stearate Citrate is widely regarded as safe for use in cosmetics. It has a low irritation and comedogenic rating, making it suitable for most skin types, including sensitive skin. No significant safety concerns have been reported in standard use concentrations.
Research notes
Research supports its use as a mild emulsifier with good skin compatibility. Studies indicate it does not cause significant irritation or sensitization in patch tests. Its safety profile is well-established through industry use and regulatory approvals.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. It is listed in the CosIng database as a safe ingredient for topical use.
- Common uses
- Moisturizers, Creams, Lotions, Sunscreens, Cleansers
- Environmental note
- Derived from renewable plant sources and considered biodegradable, making it a relatively eco-friendly choice compared to some synthetic emulsifiers.
Good to know
- Glyceryl Stearate Citrate is often listed as a 'green' emulsifier because it is biodegradable and derived from renewable resources.
- It is commonly found in products labeled as 'natural' or 'gentle' but is not considered 100% natural due to the chemical esterification process.
