Solubility of Caffeine Products

Based on the product information, ingredients like Encapsulated Caffeine and Energy-Blend™ (which contains Caffeine) are described as soluble in water. Encapsulated Caffeine can be dissolved directly in water, with heat assisting the process. Energy-Blend™ is also water-soluble due to the use of hydrotrope technology.

Ethyl Alcohol (alcohol) is a common solvent in cosmetic formulations and is miscible with water. While the product descriptions for the caffeine ingredients specifically mention water solubility, alcohol could potentially be used as a co-solvent or in formulations where alcohol is desired. However, water is explicitly stated as a suitable solvent for both products.

Therefore, water is a recommended solvent for these caffeine-containing ingredients.
