What is African Black Soap?

Origins & Traditional Craftsmanship

African black soap, known as “ose dudu” in Yoruba or “alata samina” in Ghana, represents centuries of West African skincare wisdom. Authentic versions originate primarily from Nigeria and Ghana, crafted through traditional methods that combine:

  • Plant ash from banana peels, cocoa pods, palm leaves, or shea bark

  • Natural oils and butters including shea butter, palm kernel oil, coconut oil, and palm oil

  • Traditional saponification process using potash derived from plant ash

Key Differences from “Activated Charcoal Black Soap”

Traditional African Black Soap

  • Color: Brown to dark brown with irregular texture

  • Made with: Plant ash (potash)

  • Properties: Naturally antibacterial from traditional ingredients

  • Crafting: Handcrafted, often with visible texture variations

Activated Charcoal Soap

  • Color: Pure black, uniform appearance

  • Made with: Activated charcoal powder

  • Mechanism: Adsorption-based cleansing

  • Production: Machine-manufactured, smooth texture

Antibacterial & Cleansing Mechanisms

Research indicates that traditional African black soap’s cleansing properties stem from its alkaline nature and natural antimicrobial compounds found in plant ash and oils. The soap’s effectiveness against bacteria and fungi makes it particularly suitable for acne-prone and oily skin types.

The pH Controversy: Understanding Skin Barrier Impact

Why pH Matters

Healthy skin has an acid mantle with pH 4.5–5.5, which:

  • Protects against bacteria

  • Maintains barrier function

  • Prevents water loss (TEWL)

  • Supports skin microbiome

Traditional African Black Soap pH Levels

  • pH: 8–10 (alkaline)

  • Effects: temporarily raises skin pH, increases TEWL, may irritate sensitive skin

Safe Usage Strategies

  • Short contact (under 60 sec)

  • Immediate moisturizing afterward

  • Start with 2–3 times weekly

  • Optional: use pH-balancing toner

pH-Balanced Alternatives

Formulations adjusted to pH 5.5–7, combining tradition with sensitivity-friendly use.
