Summary: In this episode, I spoke with Belinda Carli from the Institute of Personal Care Sciences in an HLB 101 to help make formulating easier. HLB, or hydrophilic-lipophilic balance, of the ingredients you incorporate into your emulsions play a role in their end feel and function, but why? In our conversation, Belinda broke down HLB, how it relates to different emulsion types and why (e.g. oil-in-water or water-in-oil emulsions), and steps you can take to use this concept to improve your skills as a formulator.
