The composition of facial cleanser generally comprises an oily component, an aqueous component. Partial free surfactants and nutrients.
Oily component
Used as a solvent and emollient in facial cleanser formulations. It mainly contains mineral oil – a good solvent to remove oil and cosmetic residues. Further oily components are: isopropyl myristate, isopropyl palmitate, caprylic/capric glyceride, and lanolin, cetyl alcohol, stearyl alcohol and the like as a solvent or an emollient.
Surfactant
A mild surfactant with good cleansing action. Such surfactants include anionic, amphoteric and nonionic surfactants such as triethanolammonium dodecyl sulfate, disodium lauryl ether succinate, cocamidopropyl betaine, coco monoethanol Amide. Geropon AS-200, Jordapon CI-75, sodium lauroyl sarcosinate, and the like. As an emulsifier. Commonly used are self-emulsifying glyceryl monostearate Tween-20, Tween-80, polyoxyethylene (30) dipolyhydroxystearate and the like. In recent years. More raw materials can be used as an emulsifier for facial cleanser. Such as SalcareSC91, TinovisADM, Sepigel 501 and so on.
Foam-type facial cleanser also frequently uses sodium cocoyl isethionate, a mixture of fatty acids and the like, which can produce a rich and stable foam, which is mild to the skin and has good detergency and dispersibility. It is suitable for hard water, has good biodegradability, and does not require emulsification during preparation. Also commonly used are lauroyl sarcosinates.
Aqueous phase component
It mainly includes water-soluble polymer substances such as water, glycerin and propylene glycol. Water has a good decontamination effect and is also a good moisturizer; glycerin and propylene glycol are moisturizers: water-soluble polymer materials have a stable thickening effect.
Other components
It mainly includes flavors, preservatives, antioxidants, and the like. Flavor gives the product a good aroma. Covers the bad smell of raw materials; antioxidants prevent oxidation of oils in the formula: Preservatives prevent the growth of microorganisms in the product. Keep the product stable: the chelating agent chelate the calcium and magnesium ions in the water. Increase the cleaning effect of the product in hard water. There are also some additives with special effects. Such as antibacterial agents, whitening agents, thin fat agents and so on.
