Considering the effect of different combinations of oils & butters in a basic lotion

Let’s take some time today to see how this all comes together in choosing butters and oils for our lotions! Defining some scientific terms: Solubility, viscosity, surface tension, and interfaces Defining some scientific terms: Contact angle, wetting, refractive index, and specific gravity Defining some cosmetic chemistry terms: Spreadability, play time, cushion, drag, and melt point...

Why is the cosmetic formulator concerned with solubility, viscosity, surface tension, contact angles, wetting, refractive index, specific gravity, spreadability, play time, cushion, drag, and melting point?

I thought we’d take some time to process what we’ve learned over the last few days about these very interesting concepts by considering some emollient combinations. Defining some scientific terms: Solubility, viscosity, surface tension, and interfaces Defining some scientific terms: Contact angle, wetting, refractive index, and specific gravity Defining some cosmetic chemistry terms: Spreadability, play...

Experiments in the workshop: Emulsified sugar scrub variations – modifying the fatty alcohol

Last week, we took a look at making this luscious emulsified scrub with tucuma butter & babassu oil. Today, let’s look at a few ways we could modify it! Let’s take some of the concepts we discussed in today’s other post – Defining some cosmetic chemistry terms: Spreadability, play time, cushion, drag, and melt point –...

Member-to-member super happy wonderful sharing & caring post (September 2018)

Last month, we tried little experiment in the form of the Member-to-member super happy wonderful sharing & caring post, an open post for you to share your thoughts, ask questions, share formulas, and generally connect with other people on this blog. I’m pleased to say it was a rousing success! So I present this post...

Defining some cosmetic chemistry terms: Spreadability, play time, cushion, drag, slip & glide, and melt point

Let’s spend a little more time getting to know some formulating terms and concepts! Check out these posts from Saturday and Sunday… Defining some scientific terms: Solubility, viscosity, surface tension, and interfaces Defining some scientific terms: Contact angle, wetting, refractive index, and specific gravity As we work through these definitions, think about how these ingredients...
