What Is Polyglyceryl-3 Lactate/Laurate?

Polyglyceryl-3 Lactate/Laurate is a plant-derived ingredient made by linking together three glycerin molecules and then attaching lactic acid and lauric acid, both of which come from natural sources like corn sugar and coconut oil. The result is a gentle surfactant that has both water-loving and oil-loving parts, letting it mix oils with water so they can be rinsed away. This technology first gained traction in the early 2000s when cosmetic chemists searched for milder, eco-friendly alternatives to traditional sulfates. To produce it, manufacturers heat and combine glycerin with lactic and lauric acids in a controlled process called esterification, then purify the mixture to remove any residues. You will spot Polyglyceryl-3 Lactate/Laurate in face cleansers, micellar waters, refreshing toners, gentle body washes and even baby care products where a soft, non-stripping cleanse is essential.

Polyglyceryl-3 Lactate/Laurate’s Cosmetic Benefits/Uses

This ingredient is valued for one primary role in skincare formulas.

As a cleansing agent, Polyglyceryl-3 Lactate/Laurate helps lift away dirt, sunscreen, makeup and excess oil without upsetting the skin’s natural moisture balance. Because it is mild and biodegradable it supports gentle daily cleansing while also appealing to brands focused on sustainability.

Who Can Use Polyglyceryl-3 Lactate/Laurate

This gentle surfactant suits nearly every skin type, including dry, oily, combination and sensitive skin, because it cleans without stripping natural oils. Extremely dry or compromised skin may still want to follow with a rich moisturizer, but the ingredient itself is unlikely to worsen dryness.

Polyglyceryl-3 Lactate/Laurate is plant-derived, so it fits vegan and vegetarian lifestyles. No animal by-products are used in its production.

Current research shows no specific risks for pregnant or breastfeeding women when using this ingredient topically. That said, this is not medical advice and anyone who is pregnant or nursing should review all skincare products with a healthcare professional to be safe.

The ingredient does not make skin more prone to sunburn, so it is not considered photosensitizing. Standard daytime sun protection is still recommended for overall skin health.

Potential Side Effects/Adverse Reactions

Reactions to Polyglyceryl-3 Lactate/Laurate vary from person to person. The following are potential side effects that may occur in rare cases, but most users will not experience them when the ingredient is used correctly in a well-formulated product.

  • Mild redness or stinging especially on very sensitive skin
  • Temporary dryness or tightness if used in a high-foaming cleanser without adequate follow-up hydration
  • Allergic contact dermatitis in individuals who are allergic to any component of the ingredient
  • Eye irritation if the product accidentally gets into the eyes

If you notice any discomfort, stop using the product and seek advice from a medical professional.

Comedogenic Rating

Polyglyceryl-3 Lactate/Laurate has a comedogenic rating of 1 out of 5. It is a lightweight surfactant that remains on the skin only during the wash phase and rinses away cleanly, so it rarely has time to build up in pores. Its structure is dominated by water-friendly glycerin units instead of heavy lipids, keeping the clogging risk low.

Because of this low rating the ingredient is generally suitable for people who are prone to acne or breakouts.

Remember that the full formula matters. A cleanser loaded with rich oils or not rinsed properly could still cause congestion even if this single ingredient is low risk.

Summary

Polyglyceryl-3 Lactate/Laurate is a plant-derived cleansing agent that grabs dirt, sunscreen and excess oil then whisks them away without stripping moisture. It achieves this by pairing water-loving glycerin chains with oil-loving lauric and lactic parts, giving it the ability to bridge oil and water.

The ingredient is growing in popularity as brands search for gentle sulfate-free and eco-friendly alternatives, though it is still less common than older workhorse surfactants.

Current research shows it to be very safe for most users with only rare irritation or clogging issues. Even so, it is smart to perform a quick patch test when introducing any new product that contains this ingredient just to make sure your skin agrees.
