How 8 Million Bars Of Olive Oil Soap Are Handmade At This Factory In Turkey

Key Concepts

• Saponification: The chemical reaction between fats (olive oil/pomace oil) and an alkali (caustic soda) to produce soap.
• Pomace Oil: The secondary oil extracted from leftover olive pulp, used as the primary base for traditional soap.
• Caustic Soda (Sodium Hydroxide): The essential alkaline agent that triggers the breakdown of fats into soap.
• Mashara: A specific row of soap bars cut during the manual production process.
• Meshed: Traditional soft leather shoes worn by workers to prevent slipping and contamination.
• Harrow: A traditional farming tool repurposed for slicing large slabs of soap into uniform cubes.

The Traditional Soap-Making Process

The production of handmade olive oil soap is a labor-intensive, multi-stage process that prioritizes patience over speed:

1. Extraction: Olives are handpicked (November–March). Extra virgin oil is reserved for food, while the remaining pulp is pressed to extract oil for soap.
2. Boiling: The oil is boiled at approximately 180°C in 20-ton tanks heated by steam. Caustic soda is added to initiate saponification. This stage lasts two days until the mixture becomes a glossy paste.
3. Spreading: The hot mixture is poured onto a paper-covered floor. Workers manually guide the flow to ensure even distribution.
4. Cooling and Cutting: The soap rests overnight to harden. Workers wearing meshed shoes walk on the surface to scrape excess material. Using a harrow, they slice the soap into rows (mashara), yielding 1,400 to 2,500 bars per row.
5. Stamping and Drying: Each bar is hand-stamped with the manufacturer's logo. The bars are then stacked in "domes" (towers of ~7,500 bars) designed for optimal airflow.
6. Aging: The soap cures for up to six months. During this time, the color shifts from a deep olive green to a lighter shade, indicating the soap has reached the desired hardness and shelf life.

Regional Variations and Challenges

• Turkey (Dr. Olu Soaps): A large-scale operation producing 8 tons daily. They utilize steam-heated tanks and export to 25 countries, including Russia and China.
• Palestine (Nablus): Known for high-quality, expensive bars. Due to limited infrastructure, workers manually transport boiling liquid in buckets and use manual marking techniques.
• Lebanon: Employs traditional methods such as using powdered soap flakes to prevent sticking and using dyed cords to mark cutting boundaries.

Industry Challenges:

• Industrial Competition: Mass-produced synthetic detergents are cheaper and faster to manufacture, often containing up to 20 ingredients, including synthetic fragrances.
• Conflict: Political instability in the Middle East has significantly reduced the number of active traditional workshops (e.g., Nablus dropped from 40 to 15).
• Seasonality: Traditional production is limited to the 3–5 month olive harvest season, forcing factories to diversify into machine-made varieties (rose, clay, honey) to remain competitive.

Historical Context and Market Shift

• Origins: Early soap dates back to ancient Babylon and Egypt (fats mixed with ash). Olive oil soap emerged around the 10th century in Aleppo and Nablus.
• The 19th Century: Towns like Nisip became hubs for soap as a traded commodity.
• The 20th Century Decline: The rise of synthetic detergents and liquid soaps marginalized traditional bars, which were perceived as less convenient.
• Modern Resurgence: A growing consumer preference for natural, simple ingredients (olive oil, water, caustic soda) has revitalized the market, particularly for individuals with sensitive skin.

Synthesis and Conclusion

The survival of handmade olive oil soap rests on a delicate balance between preserving centuries-old craftsmanship and adapting to modern market demands. While industrial alternatives offer convenience, the traditional method—defined by its simplicity, natural ingredients, and rigorous aging process—is experiencing a revival. Factories like Dr. Olu’s demonstrate that by maintaining quality and leveraging the "natural" label, traditional producers can successfully export their heritage to a global audience, ensuring that this generational craft remains a viable economic and cultural force.
