We help you source Polyquaternium-7 in China

Our Advantages:

Our company began its operation on organic solvents in 2014, and there are currently five megaton scale plants collaborating, located in Yangzhou, Shandong, Ningxia Chemical Parks in Jiangsu, China. Annual sales exceed 10 000 tonnes per year. From 2014 to present, we have provided 28 solvents for foreign users of more than 60 +.

We have been intensely ploughing the Chinese solvent Market and are very familiar with the products that all the solvent plants in China are good at, while being well aware of the environmental and safety policies in the areas where the plants are located. We can accurately predict changes in solvent prices through changes in oil prices, which can inform customers 6-12 months in advance to be ready for transfer.

We have a 20+ year track record of working with suppliers in China and rating reports on them, and we keep our suppliers updated with the latest news so our customers can get the latest supplier reports. We know the market well and have early warning notifications on upstream raw material prices to help you build a stable supply chain.

When selecting suppliers, our procurement specialists will audit the qualification of suppliers, conduct thorough investigations such as field visits and sample testing, and make ratings to ensure the authenticity and legality of supplier information.

We have a long-term stable cooperation with GLP laboratories, encounter customer test results and supplier test results do not match the situation, we will commission a third party to test to ensure the accuracy, authenticity and reliability of the experimental results. In this way, we can effectively control the product quality problems.

We have a long-term cooperative warehouse and can follow up packaging and labeling according to safety regulations and customer requirements. In order to effectively prevent damage to the goods in transit, we have prepared various reinforcement measures and packaging solutions.

Polyquaternium-7 is a polymeric conditioning agent and film-forming polymer. It is made up of repeating units of vinylpyrrolidone (VP) and dimethylaminopropylmethacrylamide (DMAPMA).  

It is used in hair conditioners to increase smoothness, gloss, and body. It functions by cationic association with the surface of damaged hair. 

It is also an effective hair-conditioning agent which remains primarily on the hair after rinsing. It forms a coating film on the outer scales of the hair, protected from humidity and other chemical agents such as shampoos. 

It is used in fabrics to provide a "no wrinkles, no static" finish. An oily coating on the fabric draws them into microscopic crevices by reducing the surface tension of water droplets viewed from above. It removes any contact between two pieces of material. The result is a lack of creases or wrinkle lines in the fabric because it cannot accumulate less-dense areas upon folding.


Polyquaternium-7 or polyquat is a hair-conditioning polymer. It has many applications in the industry, notably in cosmetics and hair care products such as conditioners and styling agents.

This polymer can be used as a conditioner to protect the hair from breakage on exposure to acids such as peroxide that causes the damage of weakening the cuticle layer of the hair shaft due to its inhibiting effects of proteinases enzymes that digest keratin fibers. As it reduces friction caused by rough surfaces (e.g., of skin), this makes skin smoother and more pliable, making it possible for moisturizers to penetrate deeper into skin tissues.

It is used as a styling agent in hair conditioner, hair masks, and lotion. It's an excellent film former that provides all-day protection against humidity.

In fabrics, it helps resist the formation of static electricity. It is used in fabric finishes to produce garments that repel water and have wrinkle and soil resistance properties when dry or wet.
