Ingredient review
PEG-5 Tsubakiate Glycerides
INCI: PEG-5 TSUBAKIATE GLYCERIDES
A gentle, oil-derived emollient that softens skin and hair without feeling heavy, with low irritation potential.
In plain English
PEG-5 Tsubakiate Glycerides is a modified version of camellia oil (tsubaki oil) that has been processed to mix better with water and other ingredients. It helps moisturize and soften skin and hair by forming a light, non-greasy film that reduces water loss. The 'PEG-5' part means it's been made more water-friendly, so it spreads easily and rinses off cleanly. It's considered very gentle and unlikely to clog pores.

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-5 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.

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 camellia seed oil glycerides with polyethylene glycol (PEG), resulting in a water-dispersible emollient that retains the nourishing properties of the original oil.
How it works
It sits on the surface of skin or hair, forming a thin, breathable layer that locks in moisture and smooths rough texture. Its PEG modification allows it to be easily incorporated into water-based formulas and to rinse off without leaving a greasy residue.
Pros
Lightweight feel
Unlike many oils, this ingredient absorbs quickly and leaves no heavy residue, making it ideal for daytime use and for people with oily skin.
Low irritation risk
Clinical and anecdotal evidence suggests it rarely causes stinging or redness, so it's suitable for sensitive skin types.
Cons and cautions
Semi-synthetic origin
The PEG modification means it's not a pure natural oil, which may be a drawback for consumers seeking 100% natural or organic products.
Limited research
While camellia oil is well-studied, specific studies on PEG-5 Tsubakiate Glycerides are sparse, so its long-term effects are less documented.
Best for
- People with dry or normal skin looking for a light moisturizer
- Those with oily or acne-prone skin who want a non-comedogenic emollient
- Anyone seeking a gentle conditioner for fine or limp hair
Use caution if
- Individuals with known sensitivity to PEG compounds or camellia oil
- Those strictly avoiding any synthetic processing in their skincare
Usage tips
Safety summary
PEG-5 Tsubakiate Glycerides is considered safe for cosmetic use at typical concentrations. The PEG component is low-risk, and the ingredient has low irritation and comedogenic potential. As with any ingredient, patch test if you have sensitive skin.
Research notes
Camellia oil is well-documented for its moisturizing and antioxidant benefits. PEG derivatives are widely used and reviewed by safety panels (e.g., CIR) as safe. Direct studies on this specific compound are limited, but its components are well-tolerated.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and Japan. PEG compounds are generally recognized as safe at low concentrations.
- Common uses
- Moisturizers, Hair conditioners, Cleansing oils, Serums
- Environmental note
- PEG compounds can be biodegradable, but their production involves petrochemical processing. Camellia oil is a renewable plant source.
Good to know
- Tsubaki oil is a traditional Japanese beauty oil rich in oleic acid and antioxidants.
- The 'PEG-5' indicates the average number of ethylene oxide units, which affects water solubility.
