Control components are preservatives, antibacterial agents, thickeners, emulsifiers, flavors, pigments and so on. Preservatives ensure that the product will not rot and deteriorate, antibacterial agents ensure that the product will not be infected by fungi, thickener to adjust the viscosity and flow variation, emulsifier to determine the product evenly dispersed into another substance, essence and pigment to ensure the stability of product smell and color. So, I don't know if that's what you want to know? Or do you want to know the names, the structures, the properties of the various monomer components, and if you want to know about that you can go to the INCI directory and Cos Dna for details
