Using Natural Lanolin (Cream Type) in Pearlized Shampoo

Based on the information provided:

1. Can natural lanolin be mixed into pearlized shampoo, and will it cause separation?
   For use in shampoo, Lanolin Oil (not the cream type) is recommended at a low concentration (1-2%). It should be mixed with the cleansing agents in the formula, which help to emulsify the oil into the water phase. If you still observe separation, incorporating a thickener like ClearClean can help stabilize the formula and keep the Lanolin Oil dispersed, preventing separation of the water and pearlizer.

2. Which oil is better for dissolving this type of lanolin, and does it dissolve in hot water?
   Both Lanolin Natural (the cream type) and Lanolin Oil are inherently oils and do not require dissolving. They are soluble only in oil and do not dissolve in water, regardless of temperature (hot or cold).
