PEG-7 Sunflower Glycerides
INCI: PEG-7 Sunflower Glycerides
A mild, sunflower-derived emulsifier that helps blend oil and water in cleansers and creams, with low irritation potential.
In plain English
PEG-7 Sunflower Glycerides is a semi-synthetic ingredient made by attaching a small PEG chain to sunflower oil glycerides. It acts as a bridge between oil and water, allowing them to mix into a stable cream or lotion. Because it's derived from sunflower oil, it's considered gentle and non-stripping, making it popular in mild cleansers and moisturizers.

Quick decision guide
Easy yes for most routines
PEG-7 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging PEG-7 Sunflower Glycerides.
- 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
A semi-synthetic emulsifier created by reacting sunflower oil glycerides with ethylene oxide (PEG-7). The sunflower base provides a natural origin, while the PEG chain gives it water-loving properties.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a smooth, stable emulsion. This helps cleansers remove makeup and sunscreen without leaving a greasy residue, and helps creams feel light and spreadable.
Pros
Gentle on skin
Unlike harsher sulfates, PEG-7 Sunflower Glycerides cleanses without stripping the skin's natural moisture barrier, making it suitable for daily use on sensitive or dry skin.
Plant-derived base
The sunflower oil origin means it comes from a renewable, widely available source, appealing to those who prefer naturally derived ingredients.
Cons and cautions
Ethoxylation concerns
The PEG process can produce trace amounts of 1,4-dioxane, a potential contaminant. However, reputable manufacturers purify the ingredient to safe levels.
Not fully natural
Despite the sunflower base, the addition of PEG makes it semi-synthetic, which may not appeal to those seeking 100% natural formulations.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone who prefers plant-derived ingredients in their skincare
Use caution if
- Those who strictly avoid all PEG compounds or ethoxylated ingredients
Usage tips
Safety summary
PEG-7 Sunflower Glycerides is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with 1,4-dioxane, but manufacturers are required to keep levels within safe limits. It has low irritation and comedogenic potential.
Research notes
Research on PEG-7 Sunflower Glycerides specifically is limited, but the broader class of PEG glycerides has been reviewed by the Cosmetic Ingredient Review panel and found safe for cosmetic use. Studies confirm low skin irritation and good emulsifying properties.
Common label clues
- Typical concentration
- 1% to 10%
- 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
- Cleansers, Moisturizers, Body washes, Makeup removers
- Environmental note
- Sunflower oil is a renewable resource, and the ingredient is generally considered biodegradable. However, the ethoxylation process requires energy and chemical processing.
Good to know
- PEG-7 Sunflower Glycerides is often used in 'oil-to-milk' cleansers that transform from an oily texture to a milky lotion when mixed with water.
- It is considered biodegradable and has a favorable environmental profile compared to some petroleum-based emulsifiers.
