Methyl Lactate ●
TL;DR. This ingredient is primarily used as a solvent and carrier, helping dissolve fragrance materials, actives, and other formula components. It can also support spreadability and sensory feel in leave-on or rinse-off products.
What does Methyl Lactate do in a cosmetic formula?
This ingredient is primarily used as a solvent and carrier, helping dissolve fragrance materials, actives, and other formula components. It can also support spreadability and sensory feel in leave-on or rinse-off products.
Is Methyl Lactate clean?
Clean-beauty frameworks generally view this ingredient as low concern when used appropriately, with the main caveat being possible eye or skin irritation at higher levels because it is an active solvent. It is not a common restricted-list trigger in major clean standards.
Is Methyl Lactate sustainable?
This material can be made from fermentation-derived feedstocks and is generally regarded as readily biodegradable. Its sustainability profile is stronger when both inputs are renewable rather than fossil-derived.
Is Methyl Lactate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when produced from approved natural-origin feedstocks using permitted esterification chemistry. From a Green Chemistry perspective, it aligns well through biodegradability, effective solvency, and potential renewable sourcing.
How does Methyl Lactate work chemically?
The molecule is a small, polar, water-miscible ester with a hydroxyl group, which gives it useful solvency for moderately polar materials and some fragrance components. It is more stable in mildly acidic to neutral systems and can hydrolyze under strongly acidic or alkaline conditions, especially with heat and water present.
