Phytosphingosine (CAS 554-62-1)

Application and positioning

The sphingoid base upstream of ceramide synthesis, used both as an antimicrobial lipid and as a barrier precursor. Supplied as a high-purity crystalline solid. It dissolves in hot alcohol and is practically insoluble in water, so the melting phase of your process sets the use level you can reach. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the purity and microbiological documentation cosmetic formulators require.
