What Is Polyglyceryl-10 Pentalinoleate?
Polyglyceryl-10 Pentalinoleate is a plant-derived ingredient created by linking ten glycerin molecules with five linoleic acid units. Glycerin usually comes from vegetable oils like coconut or soybean while linoleic acid is commonly sourced from oils such as safflower or sunflower. Chemists first explored polyglyceryl esters in the 1980s as a gentler alternative to traditional surfactants. Over time the beauty industry began favoring them for their ability to moisturize skin without relying on petrochemicals or heavy silicones.
The manufacturing process starts with glycerin that is polymerized under heat to form decaglycerol. Linoleic acid is then reacted with this long glycerin chain in a controlled setting to produce the pentaester. The result is a soft wax-like substance that blends well with both oils and water-based ingredients, making it highly versatile for formulators.
You will find Polyglyceryl-10 Pentalinoleate in rich face creams, hydrating masks, anti-aging serums, cleansing balms, makeup removers and body lotions. Its ability to stabilize oil-in-water mixtures also makes it popular in tinted moisturizers and sunscreens where an even, non-greasy feel is essential.
Polyglyceryl-10 Pentalinoleate’s Cosmetic Benefits/Uses
This multifunctional ester supports both the texture and the conditioning power of a product
- Emollient: Softens and smooths the skin surface helping to reduce flakiness and give formulas a luxurious slip that glides on easily
- Emulsifying: Allows oils and water to stay blended so creams stay stable, feel lighter and deliver actives evenly without separating over time
Who Can Use Polyglyceryl-10 Pentalinoleate
This ingredient is generally friendly to all skin types. Dry and mature skin benefit from its smoothing feel while normal and combination skin enjoy the lightweight moisture. Even oily or blemish-prone skin can usually tolerate it since it does not clog pores on its own and helps keep creamy formulas from feeling heavy. People with very sensitive or allergy-prone skin should still pay attention to the full ingredient list, as reactions often stem from other additives rather than from Polyglyceryl-10 Pentalinoleate itself.
Because both the glycerin and linoleic acid used are sourced from plants, products using this ester can fit into vegan and vegetarian lifestyles. No animal-derived raw materials or by-products are needed during production.
The compound has no known hormonal activity and is not listed as a restricted substance during pregnancy. That said, anyone who is pregnant or breastfeeding should check with a doctor before adding new products to a routine, just to be safe as individual circumstances vary.
It does not make skin more sensitive to sunlight, so there is no added risk of sunburn or pigmentation when it is applied during daytime use.
Potential Side Effects/Adverse Reactions
Responses to topical ingredients vary from person to person. The points below outline potential side effects of Polyglyceryl-10 Pentalinoleate, but most users will not experience them when the ingredient is used correctly in well-formulated products.
- Mild skin irritation such as redness or a stinging feel in very reactive skin
- Allergic contact dermatitis in individuals with a specific sensitivity to polyglyceryl esters
- Breakouts if the overall product is too rich for an oily skin type
- Eye discomfort if a cleansing balm or makeup remover containing the ester is not rinsed away fully and residue enters the eyes
Should any of these issues occur discontinue use and seek advice from a healthcare professional

Rating: 1 / 5
Polyglyceryl-10 Pentalinoleate has a very low tendency to clog pores because its bulky glycerin backbone keeps the molecule from packing tightly inside follicles. The linoleic acid segments are also known to thin sebum which can help prevent congestion. That said, if the overall formula is extremely rich or layered over occlusive products some blemish-prone users might still see breakouts.
Suitable for acne-prone skin in most cases.
Formulators sometimes pair this ester with heavier oils so always consider the full ingredient list when judging pore-clogging potential.
Summary
Polyglyceryl-10 Pentalinoleate works as an emollient that softens rough patches and as an emulsifier that keeps oil and water mixed for a smooth stable texture. Its glycerin chain attracts a hint of moisture while the linoleic acid side groups add slip and skin comfort, letting creams spread easily without a greasy afterfeel.
You will spot it more often in clean beauty and indie lines that avoid PEGs but it is still less mainstream than classic emulsifiers so not every brand uses it yet.
Overall safety is high with low irritation risk, no known hormonal activity and vegan sourcing. As with any new skincare ingredient perform a quick patch test the first time you try a product containing it to make sure your skin reacts kindly.
