In plain English

Polyglyceryl-3 Dilaurate is an ingredient that helps oil and water mix together in a product so it stays smooth and doesn't separate. It's made from glycerin and lauric acid (a fatty acid found in coconut oil), so it's considered gentle and non-irritating. You'll find it in creams, lotions, and cleansers where it helps create a nice, even texture that rinses off easily without leaving a greasy feel.

Quick decision guide

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-3 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Polyglyceryl-3 Dilaurate is a semi-synthetic emulsifier made by combining glycerin (a natural humectant) with lauric acid (a fatty acid from coconut or palm kernel oil). It belongs to the polyglyceryl ester family, known for being mild and biodegradable.

How it works

In a cosmetic product, Polyglyceryl-3 Dilaurate sits at the boundary between oil and water droplets, reducing surface tension so they can mix into a stable emulsion. This prevents the product from separating and gives it a smooth, creamy consistency. Because it's a non-ionic surfactant, it's very gentle on the skin and doesn't disrupt the natural moisture barrier.

Pros

Gentle on skin

Polyglyceryl-3 Dilaurate has a very low irritation score, making it ideal for sensitive skin types and daily use without causing redness or dryness.

Lightweight texture

It helps create emulsions that feel light and non-greasy, so your moisturizer or sunscreen spreads easily and absorbs quickly without a heavy residue.

Cons and cautions

Sourcing concerns

Lauric acid is often derived from palm oil, which can be associated with deforestation unless certified sustainable. Look for RSPO-certified sources if this matters to you.

Limited standalone benefits

This ingredient is primarily a texture and stability helper — it doesn't actively moisturize or treat skin conditions on its own, so it's always used in combination with other active ingredients.

Best for

Anyone looking for a gentle, non-stripping cleanser or moisturizer
People with sensitive, dry, or eczema-prone skin who react to harsher surfactants

Use caution if

Those with a known allergy to coconut-derived ingredients (rare)

Usage tips

Check the ingredient list for 'Polyglyceryl-3 Dilaurate' if you have sensitive skin and want a gentle cleanser or lotion.

Pair with humectants like glycerin or hyaluronic acid for extra hydration in your moisturizer.

Safety summary

Polyglyceryl-3 Dilaurate is considered very safe for cosmetic use. It has low irritation and sensitization potential, and no significant toxicity concerns have been identified in available studies. It is not known to be comedogenic.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel and other regulatory bodies have concluded that polyglyceryl esters, including Polyglyceryl-3 Dilaurate, are safe as used in cosmetics. Studies show very low skin irritation and no evidence of systemic toxicity. Research is ongoing but currently supports its use as a mild emulsifier.

Common label clues

Typical concentration: 0.5% to 5%
Regulatory status: Approved for use in cosmetics globally, including by the EU Cosmetics Regulation and the US FDA (as a cosmetic ingredient). No concentration restrictions are typically imposed.
Common uses: Moisturizers, Cleansers, Serums, Sunscreens
Environmental note: Derived from plant-based glycerin and lauric acid (often from coconut or palm kernel oil). To minimize environmental impact, look for products using RSPO-certified palm oil or coconut-derived sources.

Good to know

Polyglyceryl-3 Dilaurate is considered a 'green' emulsifier because it's biodegradable and made from renewable plant sources.
It is often used in 'oil-in-water' emulsions, which are the most common type of lotion and cream.
