Ingredient review
Cholecalciferol PEG-12 Ether
INCI: CHOLECALCIFEROL PEG-12 ETHER
A PEG-modified form of vitamin D3 that may support skin barrier function, but research is limited and the ingredient is uncommon in mainstream products.
In plain English
This ingredient is a version of vitamin D3 that has been chemically linked to a PEG (polyethylene glycol) chain. The PEG part helps the vitamin D3 mix better with water, making it easier to include in water-based skincare products like serums and creams. Vitamin D3 is known for its role in skin health, but this specific modified form is not widely studied or used, so its benefits are still emerging.

Quick decision guide
Useful, but context matters
Cholecalciferol PEG-12 Ether 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 Cholecalciferol PEG-12 Ether.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Cholecalciferol PEG-12 Ether is a semi-synthetic derivative of cholecalciferol (vitamin D3) where a PEG-12 chain is attached. This modification improves the ingredient's water solubility and stability, allowing it to be formulated into water-based cosmetics.
How it works
In a cosmetic product, the PEG chain helps deliver the vitamin D3 portion to the skin. Vitamin D3 is thought to support skin cell turnover and barrier function by interacting with vitamin D receptors on skin cells. However, the specific activity of this PEG-ether form has not been extensively studied.
Pros
Water-soluble vitamin D3
The PEG modification makes vitamin D3 easier to include in water-based products like serums, which are often preferred for lightweight hydration.
Potential barrier support
Vitamin D3 is known to play a role in skin barrier health, and this derivative may offer similar benefits in a more stable form.
Cons and cautions
Limited research
There are very few studies on this specific PEG-12 ether form, so its effectiveness and safety compared to plain vitamin D3 are not well understood.
PEG concerns
Some consumers prefer to avoid PEG compounds due to concerns about manufacturing impurities or environmental persistence, though cosmetic-grade PEGs are generally considered safe.
Best for
- Those interested in novel vitamin D3 derivatives
- People looking for water-soluble vitamin D3 options
Use caution if
- Those with known sensitivity to PEG compounds
- Anyone seeking well-established, heavily researched ingredients
Usage tips
Safety summary
Based on the safety profile of vitamin D3 and PEG compounds, this ingredient is likely safe for topical use at low concentrations. However, specific safety data for this derivative is lacking.
Research notes
Research on cholecalciferol PEG-12 ether is minimal. Most knowledge comes from studies on vitamin D3 itself, which supports skin barrier function and cell regulation. The PEG modification is a common technique to improve formulation properties.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
- Regulatory status
- Not specifically restricted by major regulators like the FDA or EU CosIng, but as a derivative of a vitamin, it falls under general cosmetic ingredient safety requirements.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams
- Environmental note
- PEG compounds can be persistent in the environment, but the small amounts used in cosmetics are unlikely to cause significant impact.
Good to know
- This ingredient is not the same as plain vitamin D3 supplements or oils; it is a chemically modified version for cosmetic use.
- PEG-12 refers to the length of the polyethylene glycol chain, which affects solubility and skin feel.
