Ingredient review
Polyglyceryl-5 Dilaurate
INCI: Polyglyceryl-5 Dilaurate
A mild, non-irritating emulsifier that creates stable, lightweight formulas without stripping the skin.
In plain English
Polyglyceryl-5 Dilaurate is a gentle ingredient that helps water and oil mix together in your skincare products. Think of it as a friendly bridge that keeps your lotion or cleanser from separating into a watery mess and an oily layer. It's made from glycerin (a natural moisturizing substance) and lauric acid (a fatty acid found in coconut oil), so it's very mild and unlikely to cause irritation. You'll find it in everything from creamy cleansers to lightweight moisturizers, where it helps create a smooth, pleasant texture that rinses off easily or absorbs nicely.

Quick decision guide
Easy yes for most routines
Polyglyceryl-5 Dilaurate 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 Polyglyceryl-5 Dilaurate.
- 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
Polyglyceryl-5 Dilaurate is a non-ionic emulsifier derived from glycerin and lauric acid. It belongs to the polyglyceryl ester family, known for being gentle and biodegradable. The '5' refers to the number of glycerin units in the molecule, which influences its water-loving properties.
How it works
In a cosmetic product, Polyglyceryl-5 Dilaurate positions itself at the boundary between oil and water droplets. Its water-loving (hydrophilic) end interacts with water, while its oil-loving (lipophilic) end interacts with oils. This reduces surface tension, allowing the two phases to blend into a stable, uniform emulsion. It also helps lower the surface tension of water, making it easier to rinse away dirt and oil when used in cleansers.
Pros
Ultra-gentle on skin
Unlike some harsher emulsifiers, Polyglyceryl-5 Dilaurate has a very low irritation score, making it ideal for sensitive, eczema-prone, or compromised skin barriers.
Lightweight feel
It creates emulsions that feel silky and light on the skin, not heavy or greasy, so it works well in gel-creams and fluid lotions.
Cons and cautions
Limited pH tolerance
This emulsifier works best in a neutral to slightly acidic pH range (around 5-7). Very acidic or alkaline formulas may destabilize the emulsion, limiting its use in certain products.
Higher cost
Because it's a specialty polyglyceryl ester, it can be more expensive than commodity emulsifiers, which may slightly increase the price of the final product.
Best for
- People with sensitive or reactive skin looking for gentle cleansers and moisturizers
- Anyone who prefers lightweight, non-greasy textures in their skincare
Use caution if
- Those with a known allergy to coconut-derived ingredients (rare, but possible)
Usage tips
Safety summary
Polyglyceryl-5 Dilaurate is considered very safe for topical use. It has a low irritation and comedogenic potential, and no significant toxicity concerns have been reported in cosmetic concentrations. It is well-tolerated even by sensitive skin types.
Research notes
Research on polyglyceryl esters in general supports their mildness and effectiveness as emulsifiers. Specific studies on Polyglyceryl-5 Dilaurate are limited, but the ingredient class is well-established in cosmetic science with a strong safety profile. It is included in the EU CosIng database and is widely used in commercial formulations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of generally recognized safe ingredients). No concentration restrictions are typical for topical use.
- Common uses
- Cleansers, Moisturizers, Serums, Sunscreens
- Environmental note
- Polyglyceryl-5 Dilaurate is biodegradable and often derived from plant-based glycerin and coconut fatty acids, making it a more environmentally friendly choice compared to some petroleum-based emulsifiers.
Good to know
- Polyglyceryl esters are considered 'green' emulsifiers because they are biodegradable and often made from renewable plant oils.
- The '5' in the name indicates the average number of glycerin units, which affects how water-loving the molecule is.
