What it does:
Glycerine is naturally water-loving (the structure of the molecules make it like a magnet to water molecules) and fatty acids like oleic acid are naturally oil-loving. When you combine these qualities into one compound, you have the perfect ingredient for helping keep all of the other ingredients in a formula together! In technical terms, it’s called an “emulsifier” and if you want to visualize it at work, think of what it looks like when you mix oil and water – they quickly go their separate ways (the oil floats up and the water sinks down). If you added an emulsifier and mixed it all up, all three ingredients would remain evenly dispersed as one, uniform final product. In our Honest Deodorant, it helps create a stable mixture for a consistent, refreshing experience every time.
Why we use it:
This plant-based, mild emulsifier is an excellent alternative to the more questionable standard alternatives like polyethylene glycol (PEG) and triethanolamine (TEA). Not only that, it’s Whole Foods Premium Body Care approved – and their standards, developed by a team of scientists over the course of years, are some of the strictest available. If they give it a thumbs-up, we do, too. And the icing on the cake is that it’s also approved for use in ECOCERT Certified cosmetics — a stamp of approval that gives us great confidence in the safety and sustainability of this ingredient. (ECOCERT is based in Europe and is one of the largest organic certification organizations in the world, conducting supply chain inspections in over 80 countries!) Ester is awesome!
Why we’re featuring it today:
There are an increasing amount of sources that recommend avoiding ingredients you can’t pronounce. It’s a great starting point for trying to better understand what’s inside your products, but it certainly doesn’t mean that anything difficult to pronounce is inherently bad. Polyglyceryl-4 oleate is a great example.
