Emollient ingredient
Lysolecithin
A hydrolysed form of phosphatidylcholine (lecithin) in which one of the two fatty acid chains has been enzymatically removed, leaving a single-chain lysophospholipid. Its asymmetric structure makes it a highly efficient emulsifier and penetration enhancer at low use levels. Distinct from Lecithin (two fatty acid chains) and Hydrogenated Lysolecithin (lysolecithin with saturated fatty acid chain). Used in K-beauty and Japanese formulations to stabilise emulsions and improve skin compatibility.
Also known as: lysophosphatidylcholine, lyso-phosphatidylcholine

Benefits
- ✓Effective emulsifier at low concentrations due to single-chain amphiphilic structure
- ✓Improves skin feel and spreadability of formulations
- ✓Structurally similar to skin's own phospholipids for good skin compatibility
- ✓Enhances delivery of active ingredients across the stratum corneum
Watch for
- ⚠At high concentrations may act as a mild surfactant and disrupt barrier lipids — typically used at low levels (0.1–2%)
- ⚠Derived from soy or egg; those with soy/egg allergies should patch-test (though topical sensitization is rarely reported)
Compatibility
✓ Works well with
+ Lecithin+ Hydrogenated Lecithin+ Ceramide NP+ Glycerin
