What components are important in a shower gel?

Used daily, shower gels are products designed in a gelified liquid form dedicated to body hygiene. They are generally composed of about 70% water, 20% cleansing bases (surfactants), and a few additional components. However, what is crucial in a shower gel is the cleansing base (surfactants) which will create a delicate foam that removes a large portion of the impurities accumulated on the surface, thus cleaning the body's skin. It is recommended that the formula be composed of a blend of surfactants preferably of natural origin, particularly gentle, non-irritating, biodegradable, and well-tolerated by the skin (e.g., coco-glucoside, sodium cocoyl glutamate, caprylyl/capryl glucoside, etc...).

Other substances are also essential to the composition of a shower gel, such as the presence ofthickening agents (ex: glycerol stearate, polysorbate 20, xanthan gum, etc...) which give the gel its appearance by increasing its viscosity due to their gelling power, softening and humectant components (ex: glycerin, aloe vera juice, inulin, etc...), pH correctors (ex: citric acid, sodium hydroxide, etc...) to stabilize the preparation and adjust the pH of the shower gel to that of the skin, and one or more preservatives which serve to protect the care product against any microbial development, knowing that shower gels are mainly composed of water (an environment conducive to the development of bacteria). Finally, some shower gels may contain active ingredients or plant extracts, present in the formulation in varying quantities.
