The ingredient narratives reshaping clean beauty.
Castor Oil
aka ricinus communis · ricinus oil · ricinoleic acid
The thick, sticky, faintly sweet workhorse — used by Refy and Ceremonia in brow gels and hair oils, and used industrially across virtually all clean lipsticks and balms as a glide and structure agent. Ricinoleic acid (~90% of fatty acid content) is unique in nature and gives castor its distinctive viscosity and mild antimicrobial properties.
- unique ricinoleic acid content (~90%)
- structural backbone of clean color cosmetics
- occlusive lash/brow conditioner with anecdotal growth claims
- lip balms and tinted balms
- brow and lash conditioners
- hair oils
- color cosmetics base
Cold-pressed Indian or Brazilian-sourced is typical. Hydrogenated castor oil (PEG variants) is widely used as an emulsifier — look for non-PEG forms in clean positioning. Pairs with rosehip, jojoba, and shea in balm and lip systems.
Hair-growth claims (lashes, brows, scalp) outpace the clinical evidence. Castor wax allergy is rare but documented.
Trusted — heritage ingredient with clean-formulation utility.
