pvp in cosmetics
In recent years, the good characteristics of water-soluble polymers have made them widely used in the field of cosmetics, and many cosmetics have the addition of
water-soluble polymer compounds. The consumption of water-soluble polymer compounds in the cosmetics industry ranks fifth after that of paper, textile, food and
adhesives. Before the 1950s, people mainly used natural polymers, such as yarrow gum, acacia gum, gelatin, casein gum, etc., due to the instability of its source
and quality, as well as its vulnerability to microbial contamination, the 1960s began to gradually be replaced by semi-synthetic polymers such as cellulose
derivatives and synthetic polymers such as vinylpyrrolidone polymers. Due to the special requirements of cosmetics, the high safety and stability of PVP polymers,
their compatibility with many other compounds, and their unique and excellent solubility make them the leading products of water-soluble synthetic polymers used
in the cosmetics industry. In the structural consumption of PVP, the application in the cosmetics industry accounts for about 35% of other consumption, and the
annual use reaches 16,000 tons/year.
The amount of PVP in cosmetics
0.5 to 5%
The recommended amount of PVP in cosmetics is 0.5-5%. Specifically, PVP is widely used in daily cosmetics because of its good dispersion and film formation. It
can be used to make styling fluid, hairspray and mousse styling agent, and as a shading agent for hair care. In addition, PVP is used in shampoos to enhance foam
stability and as a dispersant and affinity agent in wave styling and hair dye.
PVP has multiple functions in cosmetics, mainly for the stabilization (colloidal protection) and stickiness of dispersions such as emulsions and suspensions, film
formation in hair care products, gelation in gel products, lubrication, moisturizing and film formation in skin care products (facial masks), and foam stabilization.
And in various cosmetic formulations as a pigment stabilizer, deodorant, deodorant, mild agent (reduce the irritating effect of some components on the skin) and
so on.
Due to its excellent surface activity, film forming properties, no irritation to skin and no allergic reaction, PVP has broad prospects for application in the daily
chemical industry, especially in cosmetics, skin care products, hair care products and washing products.
The application of PVP in cosmetics:
The research on the application of PVP in cosmetics began in the 1960s, and now it has been widely used in hair care products, skin care products, ornaments and
other aspects, among which the most prominent is the application in hair care products. As an excellent surfactant, adding PVP to shampoo can make the foam
stable. Because of its physiological compatibility, it will not cause irritation and allergic reactions to the skin, long-term use will not damage the hair, and the hair
after washing is smooth and shiny and easy to comb. Hair spray and mousse with PVP have long-lasting styling, good luster, and because PVP has certain water
absorption, it makes hair smooth and smooth without appearing dry. PVP for hair care products can be used through the selection and proportion of copolymer
monomer types. PVP, which regulates its water absorption and is suitable for dry, neutral and oily hair as a hair conditioner, has unique advantages. The main
component of hair is protein, and the molecular structure of PVP is also similar to protein, so it can be used as a supplement for hair nutrients. Long-term use of
shampoo and hair care products containing PVP can make hair black and shiny. Reduce split ends.
First illustrate the formula of PVP used in hair care and shampoo products:
Hair spray:
Composition ratio (mass percentage %)
PVP 4.0
Ethanol (95%) 70
Propylene glycol 2.0
Purified water 20
Acetylated lanolin 2.0
Essence amount
Pigment amount
The role of PVP in other cosmetics is mainly to stabilize the dispersion system such as emulsion and suspension, moisturizing and film-forming effect in skin care
products, such as PVP in sunscreen, not only moistens, but more importantly, isolates the skin from the sun by forming a film, which plays a role in protecting the
skin. In addition, PVP has special uses in other aspects, such as pigment stabilizer, deodorant, deodorant, toothpaste, shaving cream and many other cosmetics.
The application ingredients and functions of PVP in cosmetics are listed in the following table:

The application of PVP in washing products:
The excellent surface activity of PVP makes it also have a good effect as an ingredient in some washing products. PVPP crosslinked polymer PVPP is used as the
ingredient of toothpaste, which can not only remove dirt and antifouling, but also have anti-inflammatory and analgesic effects. The toothpaste formula containing
PVPP is as follows:
Composition ratio (mass percentage %)

The application of PVP in washing products:
The excellent surface activity of PVP makes it also have a good effect as an ingredient in some washing products. PVPP crosslinked polymer PVPP is used as the
ingredient of toothpaste, which can not only remove dirt and antifouling, but also have anti-inflammatory and analgesic effects.
PVP acrylic copolymer used in bath not only has the role of dispersion stabilizer, detergent, and sterilization and disinfection function, especially as a medicated
soap, soap ingredients used in the summer has a good effect, PVP both oil and water wet properties make it in the cleaning of clothing, especially in the cleaning of
hotels, restaurants with tablecloth cleaning agent has a special effect. For example, Guangzhou Jinyuan Detergent products factory with BASF production of “table
cloth net” for washing tablecloth, not only washing time is short, washed tablecloth white and soft, there is a light fragrance smell, and both sterilization and
disinfection effect.
In summary, the function of PVP in daily chemical products is mainly manifested in the following aspects:
Dispersion stability function: common skin care products, creams and other cosmetics are mostly lotions and suspensions, to make it can be placed for a long time
without precipitation deterioration, so that it is dispersed into a uniform system and has a certain stability time is very important, PVP in cosmetics an important
function is dispersion stability function.
Decontamination and washing function: PVP and its copolymer due to its specific molecular structure, on the one hand has a lipophilic, can remove clothing, hair
and skin oil, sweat stains, etc., on the other hand has a good hydrophilicity, so it is easy to wash clothes and skin stains.
Film forming, moisturizing function: This is the most common function of PVP in cosmetics, widely used in hair care products, skin care products and so on.
Sterilization, disinfection function: mainly used in washing products.
