There are many determinants of the effect of anion-cation surfactant compounding on surface activity, and there is a synergistic effect in the case of suitable structure of both parties. In the mixed system of anion-cation surfactants, due to the strong electrostatic attraction of positive/negative ions between molecules, it is easy to form a rod-shaped colloid […]

Surfactants are indispensable additives. Adding a certain amount of surfactant solvents to detergents can enhance their solubility and detergency, but due to their toxicity, they can cause significant skin irritation. The use of surfactants in large quantities is also potentially harmful to the ecosystem. In order to meet the increasing demand for health care and

Matrix raw materials are the main raw materials constituting the cosmetic dosage form, accounting for a relatively large proportion of the cosmetic formulations, generally divided into oily raw materials, powder raw materials, colloidal raw materials, surfactants, solvents and so on. Oil raw materials is the formation of a variety of creams, emulsions cosmetics base materials,

What is the difference between essential oils and serum oils? What are the differences in potency ingredients? The concentration of essential oils and essential oils is not the same, the essential oil content of essential oils is relatively low usually around 5%, essential oils are 100% extraction. In the method of use, the essence of

Questions. 1 In the same formula, an oil-controlling ingredient is added in different proportions, and all of them have an oil-controlling effect, can we say that it is caused by this oil-controlling ingredient? Is it necessary to do an oil control test on the base of the formulation (without the oil control ingredient)? To screen

Essence, the ultimate in skincare products, has quickly become an essential part of facial care over the years. However, many people still don’t know what essences are and how they work. Why do I need to use a serum? There are many types of serums on the market, and according to texture, they can be

Questions. 1 Can the HLB value be calculated to determine the stability of a cosmetic? Is this helpful for formulation design? HLB value can only roughly determine an emulsifier matching range, and it is necessary to constantly adjust the matching ratio to find the most suitable ratio. HLB value can only roughly determine whether the

According to the application of the Facial mask material, all kinds of diversified materials are being explored and applied, and new membrane cloths are emerging in an endless stream. At present, the membrane cloth materials on the market mainly include non-woven cloth, silk cloth, Tencel cloth, biofiber membrane, bamboo charcoal fiber membrane, cotton fiber membrane,

Foam problems in water treatment troubled a lot of people, debugging the initial foam, surfactant foam, impact foam, peroxide foam, circulating water treatment by adding non-oxidizing biocides generated by the foam and so on, so the use of antifoam in water treatment is relatively common, this article comprehensively introduces the principle of antifoam agent, classification,

What if the viscosity of the shampoo system is too high or too low? This is also the current wash products in the mass production of more difficult to control the point, for the problem of over-thickening, basically in the production of sodium chloride do not add a one-time can solve this problem. For the
