Information about Reservoir-Tech

Based on the information available about Reservoir-Tech (Product ID: 1246), here are the answers to your questions:

1. Can it be added to an existing cream or lotion at 3%?

   • The recommended usage rate for Reservoir-Tech is 2.5-5.0%, so using 3% is within the suggested range.
   • The mixing instruction states to "Blend to match the recipe at any stage or at the last step." While it can be added at the final step, it is generally recommended to incorporate ingredients during the formulation process to ensure proper dispersion and stability within the product base. Adding it to a finished product might not guarantee optimal results or stability compared to formulating from scratch.

2. How to mix Reservoir-Tech? Can it be stirred manually?

   • The description suggests using a "Blend" method. This typically implies using a mechanical mixer or blender to ensure the product is properly dispersed throughout the formula.
   • Reservoir-Tech is described as a clear liquid that can be dispersed but is insoluble in water or oil. Manual stirring might not be sufficient to achieve a uniform and stable dispersion, especially in a cream or lotion base. Using a blender is recommended for best results.

3. If it cannot be used with carriers 1, 2, and 3, does that mean it can be used with 4 and 5?

   • Reservoir-Tech functions differently from traditional penetration enhancers (carriers 1-5, 7). It is described as not a direct carrier but rather forms a film on the skin to help retain and gradually release active ingredients.
   • The description states that for some ingredients (like AHA, BHA), Reservoir-Tech cannot be combined with carriers 1, 2, and 3. This highlights specific compatibility considerations when using Reservoir-Tech with certain actives and those carriers.
   • The description does not state that Reservoir-Tech can be used with carriers 4 (1,2-Hexanediol) or 5 (Ethoxydiglycol). In fact, carriers 4 and 5 are mentioned as being used "in conjunction with 1,2,3" to increase transport efficiency, suggesting they work alongside the traditional carriers.
   • Given that Reservoir-Tech has a distinct mechanism (film-forming for gradual release) compared to the penetration enhancers (carriers 1-5, 7), it is not intended to be combined with carriers 1-5 and 7 unless specifically indicated. The description does not support combining Reservoir-Tech with carriers 4 or 5.
