What role does PPG-26-2G Butanol Polyether -26 play in skin care products?

PPG-26-2G Butanol Polyether -26 is an emulsifier, which can make one liquid uniformly dispersed in another immiscible liquid with tiny droplets to form a uniform and stable emulsion.

Most of the creams, lotions, makeup remover and basic cleanser are lotions, which are beneficial to skin absorption and moisturizing.

At the same time, in order to reach the shelf life of at least three years marked on the packaging box, these products need to use emulsifiers to improve their stability.

Emulsifier is also added to the facial cleansing oil. Emulsification can dissolve oily makeup and dirt on the face. If your hands are still greasy and sticky after washing, it means that the emulsification is poor. The cold temperature will affect this process, so it is best to wash it with warm water in winter.

Extended data:

Emulsifiers can be used not only in skin care products, but also in food and industry.

At this year's "3 15" party, CCTV exposed some cottage products, among which "six pure walnuts" were impressive. This fake and shoddy product is blended with additives, and there is no walnut component in it. The taste of walnut depends on walnut essence, and a can of walnut essence can produce 8000 bottles of such "walnut" products.

Acesulfame, aspartame, potassium sorbate, sodium cyclamate ... What are the chemical names that make people unknown so? Is it harmful to human body?

Mo, a professor at the School of Chemical Engineering of Northwest Normal University, said that food additives mainly give food a brand-new life, including taste, appearance and shelf life. According to their different functions, they are mainly divided into essence, sweetener, water-retaining agent, colorant, filler, bleach, defoamer, deoxidizer, coagulant, emulsifier, antioxidant, preservative and so on.

These food additives play an indispensable role in food production and are outstanding contributions made by chemical researchers to society. However, if consumers often eat foods with excessive synthetic sweeteners and preservatives, it will cause irreversible harm to human body and nervous system, especially to the elderly, pregnant women and children with weak metabolic detoxification ability.

Acesulfame-K is the fourth generation synthetic sweetener in the world, which is similar to saccharin, soluble in water, good in taste, calorie-free, and has the characteristics of non-metabolism and non-absorption in human body. It is an ideal sweetener for middle-aged and elderly people, obese patients and diabetic patients. But if eaten in large quantities in a short time, it will cause thrombocytopenia.

Aspartame: It is a natural oligosaccharide, which will not cause dental caries, has pure sweetness, low hygroscopicity and is not sticky. Many diabetics and dieters use aspartame as a sugar substitute. But aspartame is not suitable for hot drinks, because it will decompose at high temperature and lose its sweetness.

Potassium sorbate: colorless to white scaly crystals or crystalline powder, odorless or slightly odorless. It is hygroscopic and soluble in water and ethanol. It is often used as a preservative and added to food.

Sodium cyclamate: white needle, flake crystal or crystalline powder, sweet in taste. The sweetness of its dilute solution is about 30 times that of sucrose, and the price is only one third of that of sucrose. It is a commonly used sweetener in food production.

Professor Mo reminded consumers that food additives are one of the normal ingredients of food, which are essential in the process of food manufacturing and processing, and there is no harm in using them correctly and according to regulations. However, consumers should strengthen their awareness of self-protection, know more about food safety knowledge, try to buy goods produced by regular manufacturers, and don't buy foods with too bright colors, too strong tastes and abnormal tastes.
