Ingredient review
PEG-60 Tsubakiate Glycerides
INCI: PEG-60 Tsubakiate Glycerides
A gentle, camellia-derived emulsifier that helps blend oil and water while leaving skin feeling soft and conditioned.
In plain English
PEG-60 Tsubakiate Glycerides is a semi-synthetic ingredient made by attaching polyethylene glycol (PEG) to glycerides from camellia (tsubaki) oil. In skincare, it acts as an emulsifier, meaning it helps oil and water mix together so your lotion or cream stays smooth and doesn't separate. It also has mild skin-conditioning properties, so it can leave your skin feeling a bit softer after use. Because it's derived from a traditional Japanese beauty oil, it's often found in gentle, non-stripping cleansers and moisturizers.

Quick decision guide
Useful, but context matters
PEG-60 Tsubakiate 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-60 Tsubakiate 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 polyethylene glycol (PEG) with glycerides from camellia japonica seed oil (also known as tsubaki oil). It is a waxy or pasty solid that helps stabilize oil-in-water emulsions.
How it works
Its molecular structure has a water-loving (hydrophilic) PEG chain and an oil-loving (lipophilic) fatty acid portion. When added to a formula, it positions itself at the boundary between oil and water droplets, reducing surface tension so the two phases blend into a stable, creamy emulsion. This prevents your product from separating into oily and watery layers.
Pros
Gentle emulsifier
It creates stable emulsions without the need for harsh surfactants, making it ideal for sensitive skin formulas.
Adds softness
Beyond just mixing ingredients, it leaves a subtle conditioning feel on the skin, so your moisturizer or cleanser feels more luxurious.
Cons and cautions
PEG processing concerns
As a PEG derivative, there is a small risk of contamination with 1,4-dioxane during manufacturing, though reputable brands use purification steps to keep levels safe.
Not fully natural
Despite its botanical origin, the PEG modification makes it semi-synthetic, which may not appeal to those seeking 100% natural formulations.
Best for
- People with normal to dry skin who want a gentle, non-stripping cleanser or moisturizer
- Those who prefer products with plant-derived ingredients and mild emulsifiers
Use caution if
- Individuals with a known allergy or sensitivity to camellia oil or PEG compounds (rare)
Usage tips
Safety summary
PEG-60 Tsubakiate Glycerides is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace impurities (1,4-dioxane) from the PEG manufacturing process, but reputable suppliers and brands ensure these are kept within safe limits. Allergic reactions are very rare.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and concluded they are safe for use in cosmetics when formulated to minimize impurities. Specific studies on PEG-60 Tsubakiate Glycerides are limited, but its components (camellia oil glycerides and PEG) are well-studied and widely used.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products; up to 10% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics in the EU, US, and Japan. The CIR panel has reviewed PEG compounds and found them safe at typical concentrations, provided impurities are controlled.
- Common uses
- Cleansers, Lotions, Creams, Serums
- Environmental note
- PEG compounds are not readily biodegradable in all environments, but at the low concentrations used in cosmetics, their environmental impact is considered minimal. Some manufacturers are moving toward biodegradable alternatives like polyglyceryl esters.
Good to know
- Tsubaki (camellia) oil has been used in Japanese beauty rituals for centuries for its moisturizing and antioxidant properties.
- PEG-60 Tsubakiate Glycerides is considered safe by the Cosmetic Ingredient Review (CIR) panel when used as directed.
