Using emulPearl (Glycol Distearate) in Liquid Soap

Based on the information for emulPearl (Glycol Distearate), it is used as a pearlizing agent to create a pearlescent or lustrous appearance in products like creams and lotions. The product description states that it should be mixed in the oil phase or emulsifier (such as a detergent) and requires heat (around 60-80°C, specifically around 65°C for dissolution) to dissolve in oil.

To answer your questions:

1. Do you need to add oil if your liquid soap formula has no oil?
   Yes, the product description indicates that emulPearl (Glycol Distearate) dissolves in oil with heat. If your liquid soap or shower cream formula does not contain an oil phase, you would typically need to add a small amount of a suitable cosmetic oil or compatible solvent to dissolve the emulPearl using heat before incorporating it into your main shower cream base. This helps ensure it is properly dispersed and creates the desired pearlizing effect.

2. Will adding oil react with the shower cream base?
   Adding a small amount of a compatible cosmetic oil specifically for dissolving the emulPearl is generally acceptable and unlikely to cause a significant adverse reaction with most standard shower cream bases (which are primarily water and surfactants). This is a common method for incorporating oil-soluble or dispersible ingredients into aqueous surfactant systems. The oil helps to carry and disperse the pearlizing agent. However, it's always recommended to test the final formulation for stability and performance to ensure compatibility and desired results.
