Properties and Usage of Sodium Chloride in Cosmetics
Sodium chloride (common salt) is sometimes used in cosmetic formulations like creams, lotions, and sunscreens. Its primary function in these products is often as a thickener or viscosity modifier, particularly in formulations containing certain types of surfactants or polymers. It helps to increase the consistency and stability of the emulsion.
In some cases, it can also contribute to the electrolyte balance of the formulation.
If you want to add Sodium Chloride to a lotion formulation, the appropriate percentage depends heavily on the specific thickeners and other ingredients used in the formula. However, it is typically used at low concentrations, often ranging from 0.1% to 1%. Using too high a concentration can potentially cause irritation or negatively affect the stability of the formulation.
It is recommended to start with a low percentage and adjust based on the desired viscosity and the compatibility with other ingredients in your specific lotion formula.
