The products have good appearance (viscosity, pearl, etc.), flavor and color, can long-term stability, no deterioration, do not fail. Also added sensory additives such as thickeners, preservatives, pearlescent agents, flavors and coloring.
The surfactant is the cosmetic raw material for shower gels, which uses its own adsorption, surface tension reduction, penetration, emulsification, and solubilization, dispersion role, giving the product an excellent degreasing power, detergency and foam. The shower gel to select the principle of the surfactant is to find a balance between detergency and protect the skin. Both to be able to effectively remove the dirt on the body, can not take off too much grease on the skin, but does not allow to stimulate the skin and damage skin tissue.
Skin care agent is caused by dry skin, the formula should also include some skin care agent should choose to use a mild surfactant, in order to avoid excessive degreasing of the surface active agent. Including lotions, disinfectant, water retention, and other medicinal ingredients. Its function is to protect the skin effect of soothing moisturizers is essential additives. Can choose the relatively large molecular weight, water-soluble, high boiling point alcohols such as glycerol, ethylene glycol, sorbitol, and more diethylene glycol. Adsorbed on the surface of the skin in the bathing process, and not easily washed away with water. Surface evaporation of water will leave a protective film covering the skin, to prevent or slow the loss of internal moisture glutathione to keep the skin moist.
Sensory additives human skin pH is weakly acidic. The pH range is generally from 5.5 to 6.5. Therefore, the pH value of the bath gel is best consistent with this degreasing. And at this pH. value under the betaine amphoteric surfactants shows cationic properties, can play sterilization and soft efficacy. Typically it uses citric acid to adjust pH.
People's habits have a specific viscosity on shower gel. Betaine amphoteric surfactant, alkanol amide and amine oxide non-ionic surfactant are the thickening agents. Adjusting the dosage can change the viscosity of the product. In addition, you can use some water-soluble polymers such as polyethylene glycol (6000), Carbopo1 resins, cellulose derivatives, as well as sodium chloride, ammonium chloride, sodium sulfate, inorganic salts to increase the viscosity of the product. Suitable viscosity can increase the stability of the product and it is not easy to have stratification.
