Glyceryl Stearate (GMS)
Glyceryl Stearate, also known as Glyceryl MonoStearate, or GMS, is EcoCert certified.
Glyceryl Stearate is the natural glyceryl ester from stearic acid (glycerin and stearic acid) which offers skin conditioning, moisturization and hydration due to the glycerin component.
Functions as a non-ionic opacifier, thickener, and formulation stabilizer, where it also imparts a softer, smoother, feel to your emulsions.
Glyceryl stearate (GMS) is one of the most commonly used ingredients in personal care formulations. But it’s a material that is not well understood by most formulators. GMS is normally used as a low-HLB thickening agent in lamellar gel network (LGN)-based oil-in-water emulsions, often combined with fatty alcohols.
LGN-based emulsions containing thickening polymers are the most common type of oil-in-water formulations sold globally.
Glyceryl Stearate acts as a lubricant on the skin’s surface, which gives the skin a soft and smooth appearance. It also slows the loss of water from the skin by forming a barrier on the skin’s surface. Glyceryl Stearate, and Glyceryl Stearate SE help to form emulsions by reducing the surface tension of the substances to be emulsified.
An interesting characteristic of glyceryl stearate is the ability to make the oils which are combined in the emulsion non greasy, so for example Sunflower can be combined, without adding greasiness to the final product, allowing creams and lotions to be produced which carry the properties of the oil without the greasiness.
Glyceryl stearate can be used to pearlise shower gel, shampoo and hand wash if added in combination with glycerine.
How to use
Heat the glyceryl stearate to 60c – 70c within the oil stage of your formulations. Ensure the glyceryl stearate is fully dissolved into your oil stage (use agitation if required) in order to minimise the risk of graininess in your final formulation.
