Ingredient review
Steareth-60 Cetyl Ether
INCI: Steareth-60 Cetyl Ether
A reliable emulsifier that creates smooth, stable creams without common irritation concerns.
In plain English
Steareth-60 Cetyl Ether is a semi-synthetic ingredient that helps water and oil mix together in skincare products. Think of it as a friendly bridge that keeps your moisturizer from separating into a watery mess and an oily slick. It also gives creams a silky, spreadable texture that feels nice on the skin. Because it's made from a gentle type of alcohol (cetyl alcohol) and a mild ethoxylated compound, it's considered very low risk for irritation or clogging pores.

Quick decision guide
Useful, but context matters
Steareth-60 Cetyl Ether 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 Steareth-60 Cetyl Ether.
- 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 derived from cetyl alcohol (a fatty alcohol from plant oils) and ethylene oxide. It belongs to the steareth family of emulsifiers, known for their mildness and ability to create stable oil-in-water emulsions.
How it works
When mixed into a formula, Steareth-60 Cetyl Ether positions itself at the boundary between oil and water droplets. Its water-loving (hydrophilic) end grabs onto water, while its oil-loving (lipophilic) end holds onto oil. This prevents the two phases from separating, resulting in a smooth, uniform cream or lotion. It also helps thicken the product slightly, improving spreadability and skin feel.
Pros
Gentle on skin
Steareth-60 Cetyl Ether has a very low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin types.
Improves product texture
It gives creams and lotions a smooth, silky feel that spreads easily without leaving a heavy or greasy residue.
Cons and cautions
Semi-synthetic origin
Because it's made through ethoxylation, some consumers prefer to avoid it in favor of naturally derived emulsifiers.
Potential trace impurities
The manufacturing process can produce trace amounts of 1,4-dioxane, a possible carcinogen, though levels are strictly limited by regulators and are generally considered safe.
Best for
- Anyone looking for a gentle, non-irritating moisturizer or cream
- People with sensitive or reactive skin who want stable formulas without harsh emulsifiers
Use caution if
- Those who prefer completely natural or plant-based ingredients (this is semi-synthetic)
Usage tips
Safety summary
Steareth-60 Cetyl Ether is considered safe for use in cosmetics at typical concentrations. The main concern is trace 1,4-dioxane from ethoxylation, but levels are tightly regulated and generally below 1 ppm. Irritation and comedogenicity are very low.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that steareth compounds, including Steareth-60 Cetyl Ether, are safe when formulated to minimize 1,4-dioxane. No significant human or animal studies show irritation or sensitization at typical use levels.
Common label clues
- Typical concentration
- 1-5%
- Regulatory status
- Approved for use in cosmetics globally. The Cosmetic Ingredient Review (CIR) panel has deemed it safe at concentrations up to 10%.
- Common uses
- Moisturizers, Creams, Lotions, Sunscreens, Hair conditioners
- Environmental note
- As an ethoxylated compound, it may not be readily biodegradable in all aquatic environments. However, it is not classified as a persistent pollutant.
Good to know
- Steareth-60 Cetyl Ether is often used alongside other emulsifiers to fine-tune texture and stability.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at concentrations up to 10%.
