Some recipes use guar gum and xanthum gum together to increase viscosity of lotions and creams. I have to say, I thought this was quite a poor method compared with using glycerine. As oil and water do not mix we add ingredients such as emulsifiers, stabilisers and use processing methods to help our lotion stay emulsified. Unappealing consistency, poor leave-on skin feel to some people. How can we create a sufficiently stable emulsion? Start with only 1/2 tsp of xanthum gum, and add it to 1/4 cup of room temperature distilled water.

The amount of emulsifier needed for a given emulsion is highly dependent on the droplet size (ie, surface area), the emulsifier efficiency, and the composition of the two phases. When mixed into batters or tempura xanthan gum adds good cling, allowing the batter to stick more easily to the food. Some preservatives which are surface active, such as caprylyl glycol, ethylhexylglycerin, pentylene glycol can affect stability. However this category of emulsifier is getting more and more popular and can also be used to stabilize and thicken as well as to emulsify.

Within a droplet structure the emulsifier forms a monomolecular layer on the surface of the droplet and good coverage of the surface area of the droplet ensures longer term stability. An emulsion can be defined as a dispersion of one material (usually the oil phase) inside another non-miscible (water) phase. Whisk the xanthan gum into the liquid. … Then, when you add water phase (preferably warm, around 50°C), only a light stir is sufficient to distribute all xanthan gum (unless you need to stir well to form an emulsion). (If you click on the ingredient names you will be taken to some articles about these two essential ingredients.

Emulsions allow oils and butters to be applied to the skin in an aesthetically pleasing fashion and offers the formulator a great degree of formulation flexibility and easy modification of characteristics such as viscosity, feel and appearance. Step 4: Use high shear mixing at the right temperature. Xanthan gum has a very neutral flavor so it mixes well with foods without masking their flavor. However this is not a natural state – J W Gibbs, On the equilibrium of heterogeneous substances (1878), stated that “the only point in time where an emulsion is stable, is when it is completely separated”. You can also improve the dispersion of xanthan gum by first mixing it with sugar, then adding it to the liquid. Place the glycerine into a small beaker/container, add the xanthan gum and stir until fully dissolved.
