Ingredient review
Laureth-16
INCI: Laureth-16
Laureth-16 is a gentle surfactant and emulsifier that helps products foam and rinse cleanly, but it may be slightly drying for very sensitive skin.
In plain English
Laureth-16 is a synthetic ingredient that helps water and oil mix together in your cleansers and shampoos. It also creates a light foam and helps rinse away dirt without leaving a greasy film. Think of it as a helper that makes your wash products feel smooth and effective, though it can be a little drying if your skin is already dry or sensitive.

Quick decision guide
Useful, but context matters
Laureth-16 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 Laureth-16.
- 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
Laureth-16 is a polyethylene glycol (PEG) ether of lauryl alcohol, a fatty alcohol derived from coconut or palm oil. It belongs to the laureth family of surfactants, which are known for being milder than traditional sulfates.
How it works
In a cosmetic product, Laureth-16 lowers the surface tension between oil and water, allowing them to blend into a stable emulsion. It also helps create foam and lifts dirt and oil from the skin or hair so they can be rinsed away easily.
Pros
Gentle on skin
Laureth-16 is much milder than sodium lauryl sulfate (SLS), making it a good choice for daily cleansing without over-stripping the skin's natural oils.
Improves rinse-off feel
It helps products rinse cleanly without leaving a heavy residue, so your skin feels fresh and not greasy after washing.
Cons and cautions
Potential for mild dryness
Even though it's mild, Laureth-16 can still remove some natural moisture, especially if used in high concentrations or on already dry skin.
Synthetic and not biodegradable
As a PEG-derived compound, it is not biodegradable and may raise environmental concerns for eco-conscious users.
Best for
- People with normal to combination skin looking for a gentle cleanser
- Those who prefer sulfate-free but still foaming formulas
Use caution if
- Individuals with very dry or eczema-prone skin who may find even mild surfactants drying
- Anyone seeking a completely natural ingredient list
Usage tips
Safety summary
Laureth-16 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though it may cause slight dryness in very sensitive skin. Regulatory bodies like the CIR have approved its use.
Research notes
Studies on laureth compounds indicate they are mild surfactants with low skin irritation potential. Most safety data comes from broader reviews of PEG ethers and fatty alcohol derivatives, showing good skin compatibility at low concentrations.
Common label clues
- Typical concentration
- Usually 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed laureth compounds and found them safe at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Conditioners, Emulsions
- Environmental note
- Laureth-16 is derived from palm or coconut oil, which may involve deforestation concerns. It is not readily biodegradable, so it can persist in water systems.
Good to know
- Laureth-16 is often used alongside other surfactants to balance foam and mildness.
- It is not the same as sodium laureth sulfate (SLES), which is a stronger, more common surfactant.
