Hi Storm, I'm not sure I completely understand your question.
But, the basic instructions for using Salvo are as follows:
Directions for use:
1. Weigh out the required amount of your active ingredient.
2. Optional: Remove label.
3. Use a funnel to add your powdered active ingredient directly into your Salvo bottle. (Note: To prevent overflow, it is recommended to perform this step very slowly. If overflow seems inevitable, perform steps 4, 5, and 6 before adding any more of your powdered active ingredient.)
4. Shake well.
5. Place your Salvo bottle in a basin of hot (near boiling) water, and let sit for 15-20 minutes. The bottle should be submerged to the shoulder. The bottle-cap, if on, should not be in-contact with the water.
6. Remove from basin and allow to cool before use.
Technical Notes:
-Salvo is generally compatible with active ingredients that have LogP values of 1.5-4.0. Salvo’s system is designed for use with lipophilic ingredients, does not affect the polar route of stratum corneum permeation, and thus compounds with lower lipophilicity will not partition adequately into the SC lipids. Compounds with LogP values higher than 4.0 might have such high affinity for those same SC lipids that they accumulate there & don’t reach the lower levels of the epidermis at reasonable concentrations.
-Molecular weight is a good indicator of chemical surface area, which is directly related to diffusion coefficient. As such, compounds with a MW >500 are not expected to work well in this topical system.
-’Melting point’ is an indicator of solubility in skin lipids. In general, compounds with low melting points are more compatible with topical solutions than compounds with high melting points.
-Ionized species will permeate less readily than free acid forms.
BTW: what are you trying to mix, and what dose are you looking for?
