INCI: PEG-13 Sunflower Glycerides

A mild, sunflower-derived emulsifier that helps blend water and oil in your skincare products without stripping the skin.

In plain English

PEG-13 Sunflower Glycerides is a semi-synthetic ingredient made by combining sunflower oil with a small amount of polyethylene glycol (PEG). In your skincare, it acts as a gentle bridge between water and oil, allowing them to mix into a stable cream or lotion. It also helps condition the skin, leaving it feeling soft and smooth. Because it comes from sunflower oil, it's considered a milder alternative to some harsher emulsifiers.

Quick decision guide

Useful, but context matters

PEG-13 Sunflower Glycerides 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 PEG-13 Sunflower Glycerides.
  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

PEG-13 Sunflower Glycerides is a modified plant oil. It starts with sunflower oil glycerides (the fatty part of sunflower oil) and reacts them with 13 units of ethylene oxide (PEG). This process creates a molecule that can attract both water and oil, making it useful for blending ingredients that normally don't mix.

How it works

In a cosmetic formula, this ingredient sits at the boundary between water droplets and oil droplets, reducing surface tension so they can form a stable emulsion. This prevents your lotion or cream from separating. On the skin, it leaves a light, non-greasy film that helps lock in moisture and improve texture.

Pros

Gentle on skin

Derived from sunflower oil, this emulsifier has a low irritation risk and is well-tolerated even by sensitive skin types.

Stable formulas

It helps prevent your creams and lotions from separating, so you get a consistent texture every time you use the product.

Cons and cautions

PEG-related concerns

As a PEG compound, trace impurities like ethylene oxide or 1,4-dioxane can form during manufacturing. Reputable brands use purified grades that meet safety limits.

Not fully natural

Even though it starts with sunflower oil, the PEG modification makes it semi-synthetic, which may not appeal to fans of 100% natural skincare.

Best for

  • Anyone looking for a gentle, plant-derived emulsifier in their moisturizers or cleansers
  • People with dry or normal skin who want a lightweight conditioning feel

Use caution if

  • Those who strictly avoid PEG-derived ingredients due to personal preference or ethical sourcing concerns

Usage tips

Look for this ingredient in the middle to end of the ingredient list — it's typically used at low concentrations.
Pair with other gentle emulsifiers for extra stability in water-heavy formulas like serums.

Safety summary

PEG-13 Sunflower Glycerides is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace impurities (ethylene oxide, 1,4-dioxane) during manufacturing, which are tightly regulated and kept to very low levels in finished products. For most people, it poses a very low risk of irritation or allergy.

Research notes

There is limited direct research on PEG-13 Sunflower Glycerides specifically, but it belongs to a well-studied class of PEG-modified glycerides. The Cosmetic Ingredient Review (CIR) has reviewed similar PEG compounds and concluded they are safe for cosmetic use when formulated to minimize impurities. Sunflower oil itself is well-known for its skin-conditioning properties.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and found them safe when formulated to minimize impurities.
Common uses
Moisturizers, Cleansers, Serums, Sunscreens
Environmental note
Sunflower oil is a renewable resource, but the PEG process uses ethylene oxide derived from fossil fuels. Biodegradability is moderate; check individual product formulations for full environmental profile.

Good to know

  • PEG-13 Sunflower Glycerides is often used in 'natural' or 'gentle' product lines as a milder alternative to traditional PEG emulsifiers.
  • The number '13' refers to the average length of the PEG chain, which affects how water- or oil-loving the molecule is.
