Sorbeth-6
INCI: SORBETH-6
Sorbeth-6 is a gentle, synthetic ingredient that helps products clean and mix without stripping the skin.
In plain English
Sorbeth-6 is a man-made ingredient that helps water and oil blend together in your skincare and haircare products. It also helps lift dirt and oil from your skin or hair so they can be rinsed away. Because it's very mild, it's often used in gentle cleansers and shampoos that won't leave your skin feeling tight or dry.

Quick decision guide
Useful, but context matters
Sorbeth-6 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 Sorbeth-6.
- 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
Sorbeth-6 is a polyethylene glycol (PEG) derivative of sorbitol, a sugar alcohol. It belongs to a family of ingredients called ethoxylated sorbitans, which are used as mild surfactants and emulsifiers in cosmetics.
How it works
Sorbeth-6 works by reducing the surface tension between water and oil, allowing them to mix into a stable emulsion. In cleansers, it helps surround and lift away dirt, oil, and makeup so they can be rinsed off easily. Its mild nature means it cleans without stripping the skin's natural moisture barrier.
Pros
Very gentle on skin
Sorbeth-6 is much milder than traditional sulfates, making it a good choice for sensitive or dry skin types that need a non-stripping cleanser.
Versatile emulsifier
It helps blend water and oil phases smoothly, which improves the texture and stability of lotions, creams, and cleansers.
Cons and cautions
Synthetic origin
Sorbeth-6 is manufactured using ethylene oxide, which raises environmental and processing concerns, though the final ingredient is considered safe in cosmetics.
Limited biodegradability
Like many PEG-based ingredients, Sorbeth-6 may not break down quickly in the environment, which is a consideration for eco-conscious consumers.
Best for
- People with normal to dry skin looking for a gentle cleanser
- Those who prefer mild, non-stripping shampoos
Use caution if
- Individuals with known sensitivity to PEG compounds (rare)
- Those seeking 100% natural or plant-derived ingredients only
Usage tips
Safety summary
Sorbeth-6 is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. However, as a PEG derivative, some consumers prefer to avoid it due to concerns about ethylene oxide residues, though these are tightly regulated.
Research notes
The Cosmetic Ingredient Review (CIR) has evaluated PEG derivatives and found them safe for cosmetic use. Studies indicate low skin irritation and sensitization potential. No significant human or animal studies specifically on Sorbeth-6 are widely cited, but the broader class is well-documented.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. The Cosmetic Ingredient Review (CIR) panel has deemed PEG derivatives safe as used in cosmetics.
- Common uses
- Cleansers, Shampoos, Body washes, Lotions
- Environmental note
- Sorbeth-6 is synthetic and may have moderate persistence in water systems. Look for products with biodegradable surfactants if environmental impact is a priority.
Good to know
- Sorbeth-6 is often used in 'sulfate-free' cleansers as a gentle alternative.
- It can also function as a humectant, helping to retain moisture in the skin.
