Executive Brief

Soapbottle has launched “Soapbottle Solids,” a highly concentrated solid soap bar designed to eliminate the need for single-use plastic bottles and pumps. While the company’s long-term vision involves a rigid soap-based container for liquids, this intermediate solution offers an immediate plastic-free alternative.

The 150g bars are engineered to be more durable than conventional soaps, with a 3 oz bar offering the functional equivalent of approximately 12 oz of liquid soap. By removing the water content found in liquid formulas, Soapbottle reduces production water usage and transport weight. The system features a biodegradable design and a unique integrated hanging mechanism, positioning it as a zero-waste solution for the personal care market.

Keywords: Solid Soap, Plastic-free Packaging, Zero Waste, Biodegradable, Concentrated Formula.

Technical Intelligence

1. Core Technology / Process

• Concentration: The formulation removes the water carrier found in liquid soaps, resulting in a highly concentrated solid matrix.
• Production: Reported to consume significantly less water during manufacturing compared to liquid equivalents.
• Packaging Design: Utilizes a “two-in-one” gift and shipping box where the shipping label section tears away, leaving a clean gift box to avoid secondary packaging waste.

2. Key Ingredients / Specifications

• Format: Solid soap bar, approximately 150g weight.
• Dimensions: ~11 cm x 5.5 cm x 2.5 cm.
• Accessories: Includes a plastic-free cotton ribbon (manufactured in a German weaving mill) for hanging and drying the bar.
• Material: Biodegradable soap formula; free from plastic containers.

3. Performance Data

• Equivalency: 3 oz of solid bar soap is functionally equivalent to ~12 oz of liquid soap.
• Durability: One bar lasts approximately 2-4 months with regular use.
• Efficiency: Lathers faster than watered-down liquid soaps, enhancing user experience and longevity.

4. Market / Sustainability

• Waste Reduction: Eliminates single-use plastic bottles and pumps typically used for liquid hand wash.
• Future Roadmap: Serves as a market entry product while the company develops its “liquid-in-a-packaging-made-from-soap” concept.
• Industry Context: Joins other solid format initiatives from major players like Procter & Gamble (shampoo bars for Head & Shoulders, Pantene) and BBDO (bottle-shaped solid shampoo).
