The CosIng database functions: Introduction and A

by

This series has been written by Natalie Skiller, known as the awesome formulator for Sweet Little Crumb (Facebook, Instagram). It’s my absolute honour to be able to share Natalie’s work with you!  The CosIng Database lists 83 functions. There was 89 but the database is a living document and gets updated so some of these...

Q&A: Let’s define some acronyms!

by

In the December Q&A, Marta suggested, The glossary under Resources is a wonderful thing. Would you consider creating a list of the acronyms that you’ve used in your writing (e.g. AHA, DLS, CMC, GLA, HEC, INCI, MSM, NF, NMF, PF, SC, TEWL, TJ, ARGH)? You always define the acronym when it is first introduced. But,...

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

by

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?

by

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...

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

by

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...
