Ingredient review
PPG-7/PEG-30 Phytosterol
INCI: PPG-7/PEG-30 Phytosterol
A gentle, plant-derived emulsifier that helps blend oil and water in formulas while leaving a smooth, non-greasy feel on skin.
In plain English
This ingredient is a modified plant sterol (a natural fat-like compound from plants) that has been processed with a small amount of synthetic chemistry to make it water-friendly. In skincare, it acts as a bridge between oil and water, helping to create stable, creamy lotions and serums. It also softens and conditions the skin without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
PPG-7/PEG-30 Phytosterol 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 PPG-7/PEG-30 Phytosterol.
- 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 compound made by attaching short chains of propylene glycol (PPG-7) and polyethylene glycol (PEG-30) to phytosterol, a natural plant-derived sterol. This modification makes the normally oil-loving sterol able to mix with water, turning it into a versatile emulsifier and skin conditioner.
How it works
In a formula, the PPG and PEG chains allow the molecule to dissolve in water, while the phytosterol portion remains attracted to oils. This dual nature lets it surround tiny oil droplets and suspend them in water, creating a stable emulsion (like a lotion). On skin, the phytosterol part mimics natural skin lipids, helping to reinforce the skin barrier and reduce moisture loss.
Pros
Gentle emulsifier
It creates stable, creamy emulsions without the irritation potential of some harsher emulsifiers, making it suitable for sensitive skin formulas.
Barrier-friendly
The phytosterol portion mimics natural skin lipids, helping to reinforce the skin barrier and reduce transepidermal water loss (moisture escaping from skin).
Cons and cautions
PEG content
Contains PEG (polyethylene glycol) chains, which some consumers avoid due to concerns about potential impurities from manufacturing, though cosmetic-grade PEGs are considered safe by regulators.
Not fully natural
Despite the plant-derived sterol, the PPG and PEG modifications make it a semi-synthetic ingredient, which may not align with all natural or minimalist skincare philosophies.
Best for
- Anyone using lotions or creams who wants a stable, elegant texture
- People with normal to dry skin looking for gentle barrier support
Use caution if
- Those who strictly avoid all PEG compounds or synthetic processing
Usage tips
Safety summary
PPG-7/PEG-30 Phytosterol is a well-tolerated, low-irritation ingredient with a good safety profile. The PEG component is cosmetic-grade and purified to remove impurities. Regulatory bodies and expert panels consider it safe for use in skincare.
Research notes
Research on this specific compound is limited, but studies on phytosterols in general support their role in skin barrier repair and anti-inflammatory effects. The safety of PPG and PEG compounds in cosmetics has been extensively reviewed and confirmed by the CIR panel.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Moisturizers, Serums, Cleansers, Sunscreens
- Environmental note
- The PPG and PEG components are synthetic and may not be readily biodegradable, though the overall environmental impact is considered low at typical cosmetic concentrations.
Good to know
- PPG-7/PEG-30 Phytosterol is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use concentrations.
- It is often used in 'water-in-oil' emulsions, which are especially moisturizing for dry skin.
