A Bar of Contrary's Whey Goat Milk Soap

Compounding the Soap

 

Pharmacy & Soap Making

Pharmacy and soap making share a common thread in that both require a knowledge of compounding. Ellie’s challenge was to craft a product with shea butter but without using additives, fragrances, or essential oils. She chose ingredients weighted towards the other key properties of a quality goat milk soap—lathering well, long lasting, cleansing, as well as conditioning the skin.

The Conditioning Properties

Conditioning is a term commonly used to describe the emollient and humectant properties of an ingredient.

  • Emollients increase the skin’s water content by reducing evaporation.
  • Humectants attract water to the upper layer of the skin.

Therefore, the conditioning properties of an ingredient allow the external layers of the skin to remain softer and more pliable; this in turn promotes the natural elastic properties of skin.

Fatty Acids—the Backbone of Soap Making

The oils and the shea butter contain fatty acids, which are the backbone of soap making. Choosing the right fatty acids reminded Ellie of baking a pie crust. A crust requires flour, water, and fat—which can be butter, shortening, animal fat or oil. How one combines these basic ingredients will result in either a delectably flaky crust or, well, not. Ellie needed to select oils with attributes that, once combined with goat milk and sodium hydroxide (lye), would achieve the perfect balance of nature and science to nurture the skin.  

“I’ve been using Contrary’s Whey Goat Milk Soap exclusively for a few years now and can easily say I won’t turn back to regular soap ever again. Before switching to Contrary’s Whey goat milk soap, my dry itchy skin would keep me up at night, especially in the winter months, but now I rest easily and am able to shower before bed without a problem. Great soap for everyone, but a must-have for sensitive skin.”
