Ingredient review
Sorbeth-30
INCI: SORBETH-30
Sorbeth-30 is a gentle, water-loving humectant that helps hydrate the skin and improve product texture without clogging pores.
In plain English
Sorbeth-30 is a semi-synthetic ingredient made from sorbitol (a natural sugar alcohol) and ethylene oxide. In skincare, it acts like a sponge that pulls water into the outer layer of your skin, helping it feel softer and more hydrated. It also helps other ingredients mix well with water and gives products a smooth, non-greasy feel. Because it's non-comedogenic and low-irritation, it's generally safe for most skin types, including sensitive and acne-prone skin.

Quick decision guide
Useful, but context matters
Sorbeth-30 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-30.
- 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-30 is a polyethylene glycol (PEG) ether of sorbitol, a sugar alcohol found naturally in fruits. It is produced by reacting sorbitol with about 30 units of ethylene oxide, resulting in a water-soluble, mild humectant and surfactant.
How it works
Sorbeth-30 works by attracting and holding water molecules from the environment or deeper skin layers to the stratum corneum (the outermost skin layer), increasing hydration. It also reduces the surface tension of water, helping other ingredients spread evenly and improving the overall texture of a formula.
Pros
Gentle hydration
Sorbeth-30 provides effective moisture without the sticky or heavy feel of some oils, making it ideal for lightweight lotions and serums.
Low irritation potential
With a low irritation and comedogenic rating, it is suitable for sensitive and acne-prone skin, reducing the chance of breakouts or redness.
Cons and cautions
PEG-derived concerns
As a PEG compound, Sorbeth-30 may be produced using ethylene oxide, which some consumers prefer to avoid due to potential trace impurities (though cosmetic-grade PEGs are purified).
Less researched than alternatives
Compared to humectants like glycerin or hyaluronic acid, Sorbeth-30 has fewer published studies on its long-term skin benefits and safety.
Best for
- People with dry or dehydrated skin looking for a lightweight humectant
- Those with sensitive or acne-prone skin who need a non-comedogenic moisturizing ingredient
Use caution if
- Individuals who prefer to avoid PEG-derived ingredients due to personal or environmental concerns
Usage tips
Safety summary
Sorbeth-30 is considered safe for cosmetic use at concentrations up to 5% based on industry safety assessments. It has low acute toxicity and is not a significant skin irritant or sensitizer. However, as a PEG derivative, some consumers may prefer alternatives due to concerns about ethylene oxide residues, though cosmetic-grade ingredients are purified to meet safety standards.
Research notes
Research on Sorbeth-30 is limited compared to more common humectants. The Cosmetic Ingredient Review (CIR) has evaluated PEG sorbitan derivatives and found them safe for use in cosmetics. Most evidence comes from formulation studies rather than clinical trials on skin health.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific restrictions at typical concentrations.
- Common uses
- Moisturizers, Serums, Cleansers, Toners
- Environmental note
- PEG compounds can be slow to biodegrade in aquatic environments; however, Sorbeth-30 is generally considered low-risk when used in rinse-off products.
Good to know
- Sorbeth-30 is often used in combination with other humectants to boost overall hydration.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use concentrations.
