Even though glycerine has been a staple in my stockroom for ages, it has remained one of those 'background ingredients'.
But that all changed this year.
These past few months, glycerine has made its way into a front and center position due to a series of glycerite how-to's on this blog.
Since you ask.
A glycerite is an extract made with herbs (flowers, or other substance) using glycerine as the main medium of extraction – a glycerine extract, if you will.
That picture up there is a lemon glycerite being strained (and yes, it smells deliciously of fresh lemon).
My recent glycerite how-to's have been so popular with you lovely readers that I have gotten all kinds of feedback and questions from you, so today we're going to take a closer look at glycerine.
Glycerine = GlycerolGlycerine is also known as glycerol. It's a clear, viscous (read: thick-ish, syrup-y) liquid that is sweet to the taste, slightly sticky to the touch, and categorized as non-toxic.
Glycerine has multiple uses within the food, medical, and cosmetics industries. It has gazillions of applications.
Yes, I'm exaggerating, but it really is very widely used.
As a barely-scratch-the-surface kind of list, you'll find glycerine as a component of
- food syrups
- e-cigarette liquid
- and this list could go on for a very long time....
Glycerine Fun Fact
Glycerine functions beautifully as a 'water-look-alike' in photography and film studios because it stays where it is put until the shot is done. (Now you know how they can 'capture' that perfect moment of dewy-freshness under a million hot lights that would make real water evaporate in seconds).
Glycerine can be made from both animal and vegetable sources. Vegetable glycerine is most often made from soy, palm or coconut. The non-plant-based version of glycerine is made from animal tallow.
Both Animal and Vegetable
PropertiesIn skin care products, glycerine functions as a humectant – drawing moisture to the skin when it comprises under a certain percentage of a formula. It is generally recommended to keep the total content of glycerine to under 10%.
Added at higher percentages, glycerine can do quite the opposite and draw moisture from the skin.
Dosage is everything when it comes to glycerine.
Another cool thing glycerine can do is function as a preservative, or aid to a preservative – and, again, dosage is pretty much the key.
UsesA proven ingredient with a long history of use, glycerine is an ideal addition to creams, lotions, serums, tonics, face mists and other products where moisture-boosting is desired.
Soapy goodness: I'm sure you've tried (or at least heard of) glycerine soap, which is often recommended for sensitive skin types.
Glycerine soap is easily recognizable because of its translucent quality.
Guess which one of the soaps below has glycerine?
Ok, that was a total trick question because hand-crafted soap (such as the 2 you see here) will always have a content of glycerine – even if the soap is not translucent. Companies that mass-produce soap will almost always separate out the glycerine to be sold and used in other products.
The glycerine content of artisan soap could very well be why many people with sensitive or very dry skin will better tolerate them. Count yours truly as one.
