A Primer on Micelle Formation and Packing Parameters of Surfactants

Discover how micelle formation and surfactant packing parameters shape the products you formulate every day. In this deep dive, we break down the critical micelle concentration, the packing parameter equation, and how molecular structure predicts the microstructure and why it matters for viscosity, foam, skin mildness, and oil loading.

Understanding Lipid Organization in the Stratum Corneum and Why It Matters for Formulation

The skin barrier is more than just a layer of dead cells, it's a highly organized lipid matrix that determines how well your skin holds moisture, responds to stress, and resists external aggressors. We break down the composition of the stratum corneum lipid mortar, how packing arrangements govern barrier function, and what shifting lipid ratios mean for formulating effective barrier products.

How Emollient Structure Affects Texture, Slip, and After-Feel in Formulations

Choosing the right emollient is one of the trickiest parts of formulation and defaulting to your go-to ingredient every time probably isn't serving your formula. Read on to explore how emollient chemical structure directly governs viscosity, spreadability, slip, and after-feel and how you can make smarter, more intentional selections from the start.
