Ingredient review
Propylene Glycol Linoleate
INCI: Propylene Glycol Linoleate
A gentle emollient that helps soften skin and improve product texture, but offers no unique benefits over more common alternatives.
In plain English
Propylene Glycol Linoleate is a semi-synthetic ingredient made by combining propylene glycol (a common moisturizing alcohol) with linoleic acid (an omega-6 fatty acid found in plant oils). In skincare, it acts as an emollient, meaning it fills in the tiny gaps between skin cells to make the surface feel smoother and softer. It also helps other ingredients spread evenly and can improve the feel of creams and lotions. While it is generally well-tolerated, it is not a standout ingredient and is often used in small amounts as a texture enhancer rather than a primary active.

Quick decision guide
Useful, but context matters
Propylene Glycol Linoleate 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 Propylene Glycol Linoleate.
- 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
An ester formed from propylene glycol and linoleic acid, used primarily as an emollient and skin-conditioning agent in cosmetic formulations.
How it works
It sits on the skin's surface, forming a thin, non-greasy film that reduces water loss and makes the skin feel softer. It also helps other ingredients spread more evenly and can improve the overall sensory feel of a product.
Pros
Gentle on skin
Propylene Glycol Linoleate has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Improves product feel
It helps creams and lotions spread smoothly without leaving a heavy or sticky residue, enhancing the user experience.
Cons and cautions
Not a standout active
It provides basic emollient benefits but does not offer unique or potent skincare effects like antioxidants or peptides.
Potential for mild sensitivity
Although rare, some individuals with very sensitive skin may experience mild irritation, especially if they are reactive to propylene glycol.
Best for
- People with normal to dry skin looking for a gentle emollient
- Those who prefer lightweight, non-greasy moisturizers
Use caution if
- Individuals with known sensitivity to propylene glycol or linoleic acid derivatives
Usage tips
Safety summary
Propylene Glycol Linoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with known sensitivity to propylene glycol should exercise caution.
Research notes
Limited direct research on Propylene Glycol Linoleate specifically, but its components (propylene glycol and linoleic acid) are well-studied and considered safe in cosmetic use. The Cosmetic Ingredient Review (CIR) panel has evaluated similar esters and found them safe.
Common label clues
- Typical concentration
- Usually 0.5% to 5% in leave-on products
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with no known restrictions at typical concentrations.
- Common uses
- Moisturizers, Cleansers, Makeup removers, Body lotions
- Environmental note
- Propylene Glycol Linoleate is semi-synthetic and biodegradable, but its production involves chemical processing of plant-derived fatty acids.
Good to know
- Propylene Glycol Linoleate is often used in combination with other emollients to achieve a specific texture.
- It is not the same as pure propylene glycol, which can be more drying for some people.
