Interview: Formulating with Plant-Powered Actives — A Rare Beauty Chemist Speaks
We talk to Rare Beauty’s lead chemist about the promise and pitfalls of plant-powered actives in 2026 — sustainability, efficacy, and sourcing challenges.
Interview: Formulating with Plant-Powered Actives — A Rare Beauty Chemist Speaks
Hook: Plant-derived actives are everywhere in marketing, but is the science keeping pace? Our conversation with Rare Beauty’s lead chemist cuts through the hype and lays out what R&D teams must do to ship safe, effective plant-powered products.
Excerpted Q&A
Q: What changed between 2023 and 2026?
A: The supply chain matured. We finally have contractable supply for certain bio-derivatives with decent impurity specs. That allows us to choose greener chemistries without sacrificing performance.
Q: Are plant actives always better?
A: Not always. Plants introduce batch variability and allergen vectors. Our approach is hybrid: use plant-derived scaffolds where they make a difference and synthetic analogs where they improve stability and lower impurity risk.
Material Innovation and Practical Partnerships
One of the surprising crossovers the chemist cited was working with craft and material researchers to develop packaging adhesives and secondary components that are plant-sourced. The recent material research notes at Material Alchemy: The Evolution of Plant-Based Glues for Handicrafts in 2026 mirror a lot of what R&D teams are now prototyping.
Sourcing & Traceability
Traceability was a major theme. Chemists now demand batch-level provenance for bioactives and pair that data with supply chain mapping tools. For brand teams, publishing that provenance is a trust lever — third-party audits and lifecycle statements are table stakes.
Consumer Education and Context
Plant-powered doesn’t mean drop-in replacement. Consumers have to be educated about trade-offs: allergen risks, sustainability footprints, and performance thresholds. Editorial teams should craft deep explainers and linked resources that help shoppers make informed decisions — for instance, the vegan food sector’s approach to sustainable packaging provides useful analogies, documented in Sustainable Packaging.
Future R&D Moves
The chemist expects two big moves by 2028:
- Standardized bioactive profiles for commonly used plant extracts.
- Shared open datasets for lower-barrier model training on plant-derived ingredient stability.
Closing Advice from the Lab
A final, practical recommendation: when evaluating partners, study adjacent industry proof points — for instance, how vegan brands solve packaging and material choices and how craft innovators are replacing fossil-based adhesives. Read research like Material Alchemy and the vegan packaging playbook at Sustainable Packaging to understand the material trade-offs before committing to large-scale production.
