Our technology: Supercritical CO2 extraction method

At Sleep Inc., we use supercritical CO2 extraction to maximize the effective ingredients of plants. This method is a high-pressure extraction technique that uses carbon dioxide, and it is possible to extract useful ingredients from plants in a pure form without using any chemical solvents.

Supercritical CO2 extraction allows extraction at low temperatures, preserving the delicate ingredients of plants in their original form without destroying them. This technology allows Sleep Inc.'s products to be delivered with the original aroma, flavor, and high-purity active ingredients.

Benefits of Supercritical CO2 Extraction

  • No chemical solvents used: As no chemical solvents are used, there is no need to worry about residual solvents, allowing for safe and secure extraction.
  • High-purity extract: Impurities are eliminated as much as possible, and the plant's original active ingredients are retained in high concentrations.
  • Ideal for heat-sensitive ingredients: Extraction at low temperatures is possible, preserving the quality of heat-sensitive plant ingredients.
  • Environmentally friendly: CO2 can be reused, making it a sustainable extraction technique with low environmental impact.
  • Preserves aroma and flavor: The original aroma and flavor of the plants can be used in the product without being damaged.
