INCI: SORBETH-2 HEXAISOSTEARATE

A reliable, low-irritation emulsifier that helps create stable, creamy formulas without clogging pores.

beautyskincareemulsifier

In plain English

Sorbeth-2 Hexaisostearate is a semi-synthetic ingredient made from sorbitol (a sugar alcohol) and isostearic acid (a fatty acid). It acts like a bridge between water and oil, allowing them to mix into a smooth, stable cream or lotion. Because it's gentle and has a low risk of clogging pores, it's often used in moisturizers and cleansers for sensitive or acne-prone skin.

Quick decision guide

Useful, but context matters

Sorbeth-2 Hexaisostearate 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Sorbeth-2 Hexaisostearate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A polyethylene glycol (PEG) derivative of sorbitol esterified with isostearic acid. It functions as a non-ionic surfactant and emulsifier.

How it works

It reduces the surface tension between oil and water, allowing them to form a stable emulsion. This prevents the product from separating and gives it a smooth, uniform texture.

Pros

Gentle on skin

Sorbeth-2 Hexaisostearate has a low irritation risk, making it suitable for sensitive skin types and daily use.

Non-comedogenic

It has a low comedogenic rating, meaning it's unlikely to clog pores or contribute to breakouts.

Cons and cautions

Potential sustainability issues

The isostearic acid component may be derived from palm oil, which raises environmental and ethical concerns unless certified sustainable.

PEG-related purity concerns

As a PEG derivative, it may contain trace impurities like ethylene oxide or 1,4-dioxane if not properly purified, though reputable manufacturers ensure safety.

Best for

  • People with sensitive or reactive skin
  • Those looking for a non-comedogenic emulsifier in moisturizers or sunscreens

Use caution if

  • Individuals with a known allergy to PEG compounds (rare)

Usage tips

Look for products that list this ingredient near the middle of the INCI list for typical emulsifier concentrations.
If you are concerned about sustainability, choose brands that use certified sustainable palm oil or alternative emulsifiers.

Safety summary

Sorbeth-2 Hexaisostearate is considered safe for cosmetic use with low irritation and comedogenic potential. As with all PEG compounds, quality control during manufacturing is important to avoid impurities.

Research notes

The Cosmetic Ingredient Review (CIR) has evaluated PEG sorbitan esters and found them safe for use in cosmetics. No significant human or animal toxicity concerns have been reported at typical concentrations.
