Moroccan black soap (Beldi) is a soft, paste-like cleanser traditionally used in the hammam before exfoliation with a kessa glove. It leaves the skin clean and supple without harsh surfactants when used correctly.
Quick facts
- INCI: Potassium Olivate (and) Aqua (and) Olea Europaea Fruit Oil (and optional essential oils).
- Type: Potassium soap paste from saponified olive paste/olive oil.
- Typical pH (10%): 9.5–11.0 — alkaline like classic soaps.
- Texture/appearance: amber-to-dark brown translucent gel/paste; fragrance may be natural or added (e.g., eucalyptus).
Benefits (when used as directed)
- Efficient removal of sweat, oil and dead cells prior to mechanical exfoliation.
- Smooth, supple skin feel after warm steam and gentle scrubbing.
- Simple INCI with high olive-derived fatty-acid content; no synthetic SLES/SLS needed.
How to use with a kessa glove (hammam routine)
- Warm shower or steam for 5–10 minutes to soften the skin.
- Apply a thin layer of black soap on wet skin; leave 2–5 minutes.
- Rinse lightly, then exfoliate with a damp kessa glove using long strokes. Avoid broken/irritated areas.
- Rinse thoroughly. Optionally follow with ghassoul clay mask and a few drops of premium oil (e.g., argan).
Quality & lab ranges to publish
- pH (10%): 9.5–11.0. Report batch value.
- Total fatty matter (TFM): typical 40–60% for paste soaps (method dependent).
- Water activity/microbiology: challenge test or periodic microbiology as per GMP for rinse-off products.
- Contaminants: heavy metals/PAH within cosmetic limits for natural raw materials.
Truthful, compliant claims
- “Traditional olive-based soap paste for deep cleansing before exfoliation.”
- “Leaves skin smooth and refreshed.”
- Avoid: medical/therapeutic claims (treats eczema, cures acne, etc.).
Common variations
- Fragrance: eucalyptus, orange blossom, lavender; ensure IFRA compliance.
- Add-ins: argan oil, extracts; keep total unsaponified oils modest to preserve rinse-off.
Safety & cautions
- Alkaline pH can sting eyes and recent shaves; avoid mucous membranes & broken skin.
- Patch test for fragrance-sensitive users; provide full allergen disclosure (Annex III EU/IFRA where applicable).
- For children or very dry/compromised skin, reduce contact time and follow with emollients.
Storage & shelf life
- Close jar well to limit water ingress; store cool and away from light.
- Typical shelf life: 24 months unopened; after opening, best within 12 months.
Values above are indicative; always publish lot-specific CoA numbers (pH, TFM, microbiology) and keep documentation per cosmetic regulation and GMP.
