Score terms in plain English
Irritation risk

What it is
Sorbeth-40 Hexaoleate is a polyethylene glycol (PEG) derivative of sorbitol and oleic acid. It belongs to a family of emulsifiers that are chemically modified to be water-soluble while still interacting with oils.
How it works
In a cosmetic product, Sorbeth-40 Hexaoleate sits at the boundary between water and oil droplets, reducing surface tension so the two phases mix into a stable, creamy emulsion. This keeps the product smooth and uniform throughout its shelf life.
Pros
Effective emulsifier
Creates stable, smooth creams and lotions that don't separate, improving product feel and shelf life.
Gentle cleanser
Helps remove makeup and excess oil without stripping the skin's natural moisture barrier.
Cons and cautions
Potential heaviness
May leave a slightly greasy residue on oily or combination skin, which some users find uncomfortable.
PEG concerns
As a PEG derivative, there are purity concerns regarding potential contaminants, though cosmetic-grade versions are typically well-purified.
Best for
- People with normal to dry skin looking for a stable, creamy moisturizer
- Those who use oil-based makeup removers and want a gentle emulsifier
Use caution if
- Individuals with very oily or acne-prone skin who prefer lightweight, non-emulsified products
- Anyone with a known sensitivity to PEG compounds
Usage tips
Safety summary
Sorbeth-40 Hexaoleate is considered safe for topical use at typical cosmetic concentrations. Mild irritation is rare, but individuals with sensitive skin or PEG allergies should patch test first.
Research notes
Research on Sorbeth-40 Hexaoleate is limited, but it is a well-established emulsifier in the cosmetics industry. Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found PEG derivatives to be safe when formulated appropriately.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, subject to concentration limits and purity standards.
- Common uses
- Moisturizers, Cleansers, Sunscreens, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves petrochemicals, which have a higher environmental footprint than some plant-based alternatives.
Good to know
- Sorbeth-40 Hexaoleate is often found in rinse-off products like cleansers rather than leave-on creams.
- It is considered safe for use in cosmetics by major regulatory bodies when used as directed.
