Review of Folium Biosciences Water-Soluble Liquid

Folium Biosciences developed its proprietary Water-Soluble Liquid through nanoemulsion technology, which decreases the size of CBD’s molecules enough to make it water-soluble.

CBD oil, by nature, is a hydrophobic or non-water-soluble substance, which lowers the bioavailability or body absorption of CBD products[1]. Lower bioavailability means a larger dose is required for the product to be effective[2].

According to its website, Folium Biosciences’ Water-Soluble Liquid allows for high bioavailability and may efficiently permeate the skin. It is recommended for cosmetics products.

Review of Folium Biosciences HydroPCR™ Oil

Built with Nano-Enhanced Absorption Technology or NEAT, the HydroPCR™ Oil is a water-soluble, 4% hemp oil formula. The product is designed for ready-to-drink beverages, including bottled water.

Folium Biosciences states that HydroPCR™ Oil has higher shelf stability than CBD isolates, which tends to form large droplets in oil-in-liquid solutions, also known as Ostwald Ripening[3].

HydroPCR™ Oil delays the Ostwald Ripening due to its water solubility, which leads to more stable shelf life.


From seed-to-shelf, Forum Biosciences produces top-quality CBD products through scientifically advanced manufacturing processes. 

However, lab test results are unavailable, making it difficult to ascertain the products’ potency and purity. The company must address this limitation to improve its service.
