Ingredient review
PEG-35 Almond Glycerides
INCI: PEG-35 ALMOND GLYCERIDES
A mild, almond-derived emulsifier that helps blend water and oil in creams and lotions without heavy irritation.
In plain English
PEG-35 Almond Glycerides is a semi-synthetic ingredient made from almond oil and a process called ethoxylation. It acts as a bridge between water and oil, allowing them to mix into a smooth cream or lotion. Because it's derived from almond oil, it also adds a light, non-greasy feel to the skin. The 'PEG-35' part means it has been modified to be water-friendly, so it rinses off easily and doesn't leave a heavy residue.

Quick decision guide
Useful, but context matters
PEG-35 Almond 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-35 Almond 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 almond glycerides with ethylene oxide (PEG-35). It combines the skin-friendly properties of almond oil with the water-mixing ability of PEG compounds.
How it works
In a formula, PEG-35 Almond Glycerides positions itself at the interface of water and oil droplets, reducing surface tension so the two phases blend into a stable emulsion. This prevents the product from separating and gives it a smooth, uniform texture. On skin, it leaves a thin, conditioning film that helps retain moisture.
Pros
Gentle on skin
PEG-35 Almond Glycerides has a low irritation risk, making it suitable for sensitive skin types and daily use in moisturizers and cleansers.
Light conditioning feel
Unlike heavier oils, it leaves a non-greasy, smooth finish on the skin, which is ideal for lightweight lotions and gel-creams.
Cons and cautions
Ethoxylation concerns
The manufacturing process can create trace amounts of 1,4-dioxane, a potential carcinogen. However, reputable brands purify their ingredients to keep levels well below safety limits.
Not natural
Despite being derived from almond oil, the ethoxylation step makes it a semi-synthetic ingredient, which may not appeal to those seeking fully natural formulations.
Best for
- Anyone looking for a gentle, non-irritating emulsifier in their moisturizer or cleanser
- People with normal to dry skin who want a light conditioning effect
Use caution if
- Those who strictly avoid PEG compounds or ethoxylated ingredients due to personal preference
Usage tips
Safety summary
PEG-35 Almond Glycerides is considered safe for cosmetic use at typical concentrations. The main concern is potential contamination with 1,4-dioxane, but purification steps keep levels within safe limits. It has low irritation and comedogenic risk.
Research notes
The Cosmetic Ingredient Review (CIR) has evaluated PEG almond glycerides and found them safe for use in cosmetics. No recent peer-reviewed studies specifically on PEG-35 Almond Glycerides were identified, but its safety profile is supported by broader reviews of PEG compounds and almond-derived ingredients.
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, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed it safe at typical use concentrations.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- The ethoxylation process uses ethylene oxide, which is derived from fossil fuels. However, the ingredient itself is biodegradable under standard wastewater treatment conditions.
Good to know
- PEG-35 Almond Glycerides is often listed near the middle of an ingredient list, indicating moderate concentration.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel when used as directed.
