The substance is also known as glycerol or propanetriol and is a thick sugary alcohol, which is part of all fatty substances.
Glycerine is highly hygroscopic i.e. capable of absorbing water/steam from its’ surroundings and thereby retains moisture. This is used in cosmetics, where it is added to creams as a moisturizing and moisture-retaining ingredient.
Glycerine is also added as a stabilizer and emulsifier in order to ease and stabilize the mix of fatty and watery ingredients.
Works as an emulsifier in cosmetic products, which means that the substance enables the mix of two substance, which normally would not easily mix (for instance oil and water). In addition to this, the substance has softening, moisturizing, smoothing and anti-static effects by neutralizing the electric charge on surfaces.
