Camellia Japonica Seed Oil

Camellia Japonica Seed Oil is primarily an emollient/occlusive lipid used at relatively high concentrations in moisturizers and cleansing oils, and it is generally well-tolerated in sensitive-skin populations. Irritation and true allergy are uncommon but can occur (often related to individual plant-oil sensitivities or oxidation byproducts), so it is not scored as inert; overall it fits a very gentle profile for daily use with low but nonzero risk. Safety Notes: In commercial skincare it appears at very low levels (~0.1–1%) as a label-claim emollient in lotions, serums, cleansers, and shampoos/conditioners where the primary oil phase is built from other esters/oils. Mid-range use (~2–20%) is common in facial oils, cleansing oils/balms, and richer creams as a substantive emollient. The upper end includes consumer-sold single-ingredient camellia (tsubaki) seed oil products marketed as 100% oil for face/hair/body; this ingredient is not specifically concentration-limited by major cosmetic regulations, so the practical maximum is neat oil.
