CAMELLIA JAPONICA SEED OIL TRIACETIN ESTERS.

Valuable / SKIN CONDITIONING - EMOLLIENT

An advanced, esterified version of traditional Tsubaki oil designed for superior spreadability and a weightless finish. This precision-engineered lipid provides the antioxidant benefits of Camellia japonica without the heavy, occlusive feel of raw botanical oils.

Summary

Emollient Skin Conditioning Barrier Repair Antioxidant Delivery

Science

Mechanism of Action

By undergoing transesterification with triacetin, the dense triglycerides of Camellia oil are structurally modified into shorter-chain esters. This creates a biomimetic emollient that reinforces the lipid barrier and reduces transepidermal water loss (TEWL) while maintaining a high refractive index for a natural skin glow.

Because it is an esterified oil, it is often used at higher levels (up to 10%) as a base emollient; however, its bio-active properties regarding inflammation and brightening are documented as low as 0.1%.
