Difference between GMS and GMS SE

GMS stands for Glyceryl Monostearate, and GMS SE stands for Glyceryl Monostearate Self-Emulsifying.

The main difference lies in their emulsifying properties:

• GMS (Glyceryl Monostearate): This is a common emulsifier and thickener used in cosmetic and food formulations. Standard GMS is not self-emulsifying, meaning it typically requires the addition of a co-emulsifier (another ingredient that helps oil and water mix) to create a stable emulsion (like a cream or lotion).

• GMS SE (Glyceryl Monostearate Self-Emulsifying): This type of GMS contains a small amount of soap or other emulsifying agents added during manufacturing. This makes it "self-emulsifying," allowing it to help mix oil and water on its own to some extent. It can be used as a primary emulsifier in simpler formulations or as a thickener that also provides some emulsifying ability. The self-emulsifying property means it can potentially be used in formulations with little to no other emulsifiers, particularly for changing the texture of water-based systems (like turning a gel into a cream) or in oil-free systems. However, in formulations with significant oil content, using additional emulsifiers is often still recommended for better stability.

In summary, GMS SE has enhanced emulsifying capabilities compared to standard GMS due to the presence of additional emulsifying components, making it more versatile in certain formulation types, especially those aiming for simplicity or specific textures.
