Ingredient review
PEG-75 Shea Butter Glycerides
INCI: PEG-75 Shea Butter Glycerides
A gentle, water-friendly version of shea butter that helps blend oil and water in formulas without leaving a greasy feel.
In plain English
PEG-75 Shea Butter Glycerides is a modified form of shea butter that has been treated with polyethylene glycol (PEG) to make it dissolve in water. While regular shea butter is thick and oily, this version mixes easily into cleansers and lotions, helping them feel smooth and moisturizing without being heavy. It acts as an emulsifier, meaning it helps water and oil ingredients stay blended together so your product doesn't separate. It also leaves a soft, conditioned feel on skin.

Quick decision guide
Useful, but context matters
PEG-75 Shea Butter 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-75 Shea Butter 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 ingredient created by reacting shea butter with PEG (polyethylene glycol) to produce a water-soluble glyceride mixture. It retains the moisturizing fatty acids of shea butter but gains the ability to mix with water, making it useful in rinse-off and leave-on formulas.
How it works
The PEG chains attach to shea butter molecules, giving them a water-loving (hydrophilic) end. This allows the ingredient to sit at the boundary between oil and water droplets, stabilizing emulsions. On skin, it deposits a thin layer of shea butter lipids that help soften and smooth the skin barrier without clogging pores.
Pros
Lightweight moisture
Delivers the conditioning benefits of shea butter in a form that feels light and non-greasy, making it ideal for lotions and gel-creams.
Effective emulsifier
Helps create stable, smooth emulsions so your product stays mixed and has a pleasant, consistent texture from first use to last.
Cons and cautions
PEG purity concerns
As a PEG derivative, it may carry trace impurities if not properly refined. Look for products from brands that test for purity to avoid potential irritation.
Not natural
Despite starting from shea butter, the PEG modification makes it a semi-synthetic ingredient, which may not appeal to fans of 100% natural skincare.
Best for
- Anyone looking for a lightweight, non-greasy moisturizer or cleanser
- People with normal to combination skin who want shea butter benefits without heaviness
Use caution if
- Those who strictly avoid PEG-derived ingredients or prefer completely natural formulations
Usage tips
Safety summary
PEG-75 Shea Butter Glycerides is considered safe for topical use at typical cosmetic concentrations. The main safety consideration is the potential for trace impurities (ethylene oxide, 1,4-dioxane) in PEG ingredients, which reputable manufacturers control through purification. It has low irritation and comedogenic potential.
Research notes
The Cosmetic Ingredient Review (CIR) has evaluated PEG compounds and found them safe in cosmetics when formulated to meet purity standards. Shea butter itself is well-studied for its moisturizing and anti-inflammatory properties. Specific studies on PEG-75 Shea Butter Glycerides are limited, but its safety profile is supported by the broader safety data on PEG derivatives and shea butter.
Common label clues
- Typical concentration
- 1–5% in leave-on products; up to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed PEG derivatives safe when formulated to minimize impurities.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves petrochemical processing. Shea butter is a renewable plant resource, often sourced from West Africa.
Good to know
- PEG-75 Shea Butter Glycerides is often listed near the middle of an ingredient list, indicating a moderate concentration.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel when used as directed.
