Polyquaternium 37

Polyquaternium 37
Polyquaternium 37 is a polymeric quaternary ammonium salt. It is used in hair care products as an anti-static agent, film former and fixative.
Polyquaternium 37 is classified as :
Antistatic
Film forming
CAS Number of Polyquaternium 37:    26161-33-1
COSING REF No of Polyquaternium 37:    79206
Chem/IUPAC Name of Polyquaternium 37:    Ethanaminium, N, N, N-trimethyl-2-((2-methyl-1-oxo-2-propenyl)oxy)- chloride homopolymer

Functions of Polyquaternium 37:

Polyquaternium 37 is one of the most widely-used members of the Polyquaternium group (similar ingredients with different numbers to indicate their chemical compositions) and is an anti-static agent and film former seen primarily in hair care products. A patent filed by a European beauty company notes that Polyquaternium 37 (in conjunction with fatty alcohol and a surfactant) provides "hair conditioning composition with excellent body enhancing and volume up effect especially for fine hair and also gives hair excellent combability, elasticity and shine;" it goes on to say that it does not way hair down either.

Polyquaternium 37 works by providing a positive charge to counteract the negative charge often found in shampoos and other hair care products. They bond ionically to the hair and "and provide conditioning benefits such as ease of combing, hair alignment, elasticity and shine," according to the Hairlicious blog.

Safety Measures/Side Effects of Polyquaternium 37:

Polyquaternium 37 is considered a low hazard ingredient by the Cosmetics Database, which only notes data gaps and bioaccumulation as a concern. No other studies were found that reported any negative side effects or adverse reactions.

Details of Polyquaternium 37:
A cationic polymer molecule (a big molecule with repeated subunits and a positive charge) that acts both as a film-former and conditioning ingredient as well as a thickening agent. 

A cationic thickening and stabilizing polymer
Excellent conditioning properties for skin and hair coupled with a great sensory profile add up to a winning combination in modern hair care products. Polyquaternium 37 delivers in all areas, and is even suitable for clear formulations. The cationic polymer thickens and stabilizes, and can be processed cold or hot at various manufacturing phases. Polyquaternium 37 is free of preservatives, effective at low concentration and suitable for EO-free concepts, giving it attractive sustainability properties.

Polyquaternium 37 is a synthetic cationic polymer that can be used in cosmetic applications as a thickening, suspending, and conditioning agent. Polyquaternium 37 is compatible with a wide range of cationic and nonionic surfactants.

Polyquaternium

Polyquaternium is the International Nomenclature for Cosmetic Ingredients designation for several polycationic polymers that are used in the personal care industry. Polyquaternium is a neologism used to emphasize the presence of quaternary ammonium centers in the polymer. INCI has approved at least 40 different polymers under the polyquaternium designation. Different polymers are distinguished by the numerical value that follows the word "polyquaternium". Polyquaternium-5, polyquaternium-7, and polyquaternium-47 are three examples, each a chemically different type of polymer. The numbers are assigned in the order in which they are registered rather than because of their chemical structure.

Polyquaterniums find particular application in conditioners, shampoo, hair mousse, hair spray, hair dye, personal lubricant, and contact lens solutions. Because they are positively charged, they neutralize the negative charges of most shampoos and hair proteins and help hair lie flat. Their positive charges also ionically bond them to hair and skin. Some have antimicrobial properties.

Polyquaternium 37   
Avoid
Polyquaternium 37 is Used to keep down fly-aways due to static electricity. Also used as a hair fixative, so this means it can build up in your hair with repeated use, making it sticky or crunchy. Fine in gels or styling products, but use caution in shampoos and conditioners. There is also concern that it tends to build up in the environment.

What is Polyquaternium 37?

Polyquaternium 37 is a charged (polycationic) polymer normally used in the personal care industry i.e. Hair care.

What does  Polyquaternium 37 do for the hair?

Since they are positively charged, they neutralize the negative charges of most shampoos, relaxers, hair proteins etc. helping the hair to lay flat. Their positive charge, ionically bond to the hair. It is particularly useful to use cationic polymers on hair exposed to high alkalinity relaxers to decrease damage to hair. They attach to the hair and provide conditioning benefits such as ease of combing, hair alignment, elasticity and shine. Polyquaternium 37 also helps to reduce flyaways & static.
