Polyglyceryl-3 Lactate/Laurate

Polyglyceryl-3 Lactate/Laurate is a mild surfactant created by combining polyglycerin with lactate and laurate fatty acids. Surfactants are molecules with a dual nature: one end attracts water whilst the other attracts oils, allowing them to suspend dirt and sebum for rinsing away. This particular surfactant is valued for its plant-derived origins and gentler profile compared to more traditional cleansing agents.You'll typically find this ingredient in facial cleansers, micellar waters, and makeup removers. It works to lift impurities without disrupting the skin's natural barrier, making it…

This surfactant works through its molecular structure. The hydrophilic (water-loving) portions of the molecule bind to water, whilst the lipophilic (oil-loving) portions attach to sebum, dirt, and makeup. This action suspends impurities in the rinse water so they can be easily washed away.Unlike harsher surfactants, polyglyceryl esters are designed to interact gently with the skin's natural lipids, minimising disruption to the stratum corneum (the outermost layer). This gentler interaction is why it's often chosen for cleansers aimed at sensitive or compromised skin barriers.

Use as directed on your chosen product—typically as part of your morning and evening cleanse. Massage gently onto damp skin, then rinse thoroughly with lukewarm water. If combined with other actives (such as retinoids or acids), ensure your cleanser is pH-appropriate to avoid over-disrupting your barrier. This surfactant generally plays well with other skincare ingredients, so layering should not be problematic.

Polyglyceryl-3 Lactate/Laurate is generally well-tolerated and considered a low-irritancy surfactant. It is approved for use in cosmetics across major regulatory bodies. Patch testing is always sensible if you have very reactive or severely compromised skin.
