The Rhassoul Library
A working library for people who specify, formulate and build products with Moroccan Rhassoul.
Material Notes
Origin, performance, comparison and qualification—before the formulation begins.
What is Moroccan Rhassoul? Origin, geology and a living history.
Before it became an INCI name, Rhassoul was a place-bound mineral and a washing ritual.
02Material NoteMoroccan Lava Clay: useful properties, responsible claims and best practice.
The value is not a miracle claim. It is the set of behaviours a formulator can observe, tune and prove.
03Material NoteRhassoul vs other clays: what is genuinely different?
Colour is not identity. Origin is not performance. A useful comparison starts with mineralogy and ends at the bench.
04Material NoteFrom sample to specification: how to qualify Rhassoul for cosmetics.
A beautiful sample starts a conversation. A repeatable qualification process starts supply.
Formulation Briefs
Application routes, bench questions and development frameworks for downstream teams.
Formulation Brief 01 — Rhassoul face and body masks.
Design the drying curve, spread and rinse—not just the percentage of clay.
06Formulation BriefFormulation Brief 02 — Rhassoul for hair and scalp cleansing.
Scalp cleansing is only half the brief. Particle removal, wet combing and fibre feel decide whether the concept works.
07Formulation BriefFormulation Brief 03 — Waterless cleansing powders with Rhassoul.
Waterless at manufacture does not mean riskless at use. Design the powder, the pack and the activation ritual as one system.
08Formulation BriefFormulation Brief 04 — Rhassoul in soap, hammam and professional spa.
A professional ritual is both a formula and a service protocol. Design the hand-off between them.
