Science & Benefits

A synthetic tetraester that provides high-gloss emolliency and a rich moisture feel with zero comedogenic risk. Its unique 'four-arm' molecular structure makes it exceptionally stable and prevents it from penetrating into the sebaceous follicle. In 2026, it is the preferred lipid for high-performance, non-comedogenic moisturizers, offering the sensory benefits of heavy plant oils without the risk of inducing acne cosmetica or feeding fungal organisms.
