Emulsifiers & Surfactant Selection for Stable Cosmetics

On-Demand Course

Recorded on Feb 8, 2022

Avoid instability issues in your cosmetic emulsions (o/w, w/o, blends…) by learning about the various stabilization mechanisms, formulation methodologies, evaluation techniques & tests to cater the current market needs!

Mark Chandler will help you become autonomous in formulating stable cleansers, leave-on skin care products, shampoos, hand wash, etc., by sharing detailed insights on classes of emulsifiers & surfactant, their selection & formulation.

Why should you view this course?

Emulsifiers and surfactants play a significant role in formulating stable cosmetic products (synthetic, natural, sensory…). But, is it easy to attain desired stability with the ingredients (o/w, w/o, blends…) that aren’t compatible? Fortunately, there is a clearly defined structure that can help you get started. Join this course and:

  1. Select faster the right surfactant / emulsifier depending on your application (cleanser or leave-on skin care products) by reviewing their functions and chemistries.

  2. Manage product stability better by learning about the various stabilization mechanisms (steric, charge, pickering, polymeric…) formulation methodologies, evaluation techniques (HLB) and tests.

  3. Get expert insights on various instability challenges (droplet coalescence, flocculation, creaming, sedimentation), especially when trying to formulate more natural or sensory products.

The depth and breadth of the technical information was perfect for all levels of cosmetic scientists. We learned more details on emulsifier and surfactant systems than was previously known

I learned how to process liquid cyrstal emulsions; I was not doing it properly, or as Mark suggested. Well rounded exposure with good presentation.
