Polyquaternium-7 is an organic compound in the polyquaternium class of chemicals and used in the personal care industry. It is the copolymer of acrylamide and the quaternary ammonium salt diallyldimethylammonium chloride. [1]

Contents

Its molecular formula is: (C8H16ClN)n(C3H5NO)m. [2]

Functions

Polyquaternium-7 is used for its antistatic and film forming properties. [1]

Usage

Polyquaternium 7 is the designation established with the original association, Cosmetics, Toiletries, and Fragrance Association (CTFA), now known as the Personal Care Products Council. There are an abundance of product names containing the same or a similar active ingredient for applications outside the cosmetics and personal care industry.

Polyquaternium-7 is applied in waste treatment for laundry, emulsion breaking, sludge dewatering and drainage and retention aid. It is a cationic polyelectrolyte. [3]

Polyquaternium-7 is used as modifier, for example in shampoo, hair conditioner, hair spray, mousse, soap, gel, styling agent, shaving product, deodorant and antiperspirant. [4] The DADMAC monomer is highly hydrophilic. Absorption of moisture from the air lends "conditioning" properties to the products that contain the copolymer such as shampoos, hair and skin conditioners and other personal care products including some bar soaps.

Safety

According to its safety data sheet, it is not persistent, bioaccumulative, or toxic. [3] Not a hazardous substance or mixture according to Regulation (EC) No. 1272/2008 or EC-directives 67/548/EEC or 1999/45/EC. [3]

Scientific studies

The influence of the synthetic cationic polymer polyquaternium-7 on the rheology and microstructure of creams was investigated. [5]

Efficacy, mechanism and test methods of conditioning polymers in some shampoo formulations was investigated. [6]

Surfactant Substance that lowers the surface tension between a liquid and another material

Surfactants are compounds that lower the surface tension between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants. The word "surfactant" is a blend of surface-active agent, coined c.  1950.

Benzalkonium chloride Surfactant and antiseptic agent

Benzalkonium chloride, also known as alkyldimethylbenzylammonium chloride (ADBAC) and by the trade name Zephiran, is a type of cationic surfactant. It is an organic salt classified as a quaternary ammonium compound. ADBACs have three main categories of use: as a biocide, a cationic surfactant, and a phase transfer agent. ADBACs are a mixture of alkylbenzyldimethylammonium chlorides, in which the alkyl group has various even-numbered alkyl chain lengths.

Hair conditioner Hair care product

Hair conditioner is a hair care product used to improve the feel, appearance and manageability of hair. Its main purpose is to reduce friction between strands of hair to allow smoother brushing or combing, which might otherwise cause damage to the scalp. Various other benefits are often advertised, such as hair repair, strengthening, or a reduction in split ends.

Polydimethylsiloxane Chemical compound

Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones.

, R being an alkyl group or an aryl group. Unlike the ammonium ion and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution. Quaternary ammonium salts or quaternary ammonium compounds are salts of quaternary ammonium cations. Polyquats are a variety of engineered polymer forms which provide multiple quat molecules within a larger molecule.

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.

A fabric softener or fabric conditioner is a conditioner that is applied to laundry during the rinse cycle in a washing machine to reduce harshness in clothes that are dried in air after machine washing. In contrast to laundry detergents, fabric softeners may be regarded as a kind of after-treatment laundry aid.

A conditioner is a substance or process that improves the quality of another material. Conditioning agents used in cosmetic products are also known as moisturizers in skincare products and usually are composed of various oils and lubricants. One method of their use is as a coating of the substrate to alter the feel and appearance. For cosmetic products, this effect is a temporary one but can help to protect skin and hair from further damage.

The nitrogen center substituted with two methyl groups and two stearyl groups. The combination of long-chain hydrocarbon groups and the cationic ammonium confers surfactant- or a detergent-like properties. For professional use only, it can be found in many wares-and-equipment sanitizers as well as cleaner/sanitizer combinations that are standard in the foodservice industry – it was once a major component of fabric softeners, but has been largely phased out because of its low biodegradability. In household products, it may also be found as an ingredient in cosmetics and hair conditioners in which it is added primarily for its antistatic effects. It is also used in organic synthesis as a phase transfer catalyst to increase reaction rates in a two-phase organic-water system.

Shower gel Liquid products used for cleaning the body

Shower gel is a specialized liquid product used for cleaning the body during showers. Not to be confused with liquid soaps, shower gels, in fact, do not contain saponified oil. Instead, it uses synthetic detergents derived from either petroleum or plant sources.

Cetrimonium chloride, or cetyltrimethylammonium chloride (CTAC), is a topical antiseptic and surfactant. Long-chain quaternary ammonium surfactants, such as cetyltrimethylammonium chloride (CTAC), are generally combined with long-chain fatty alcohols, such as stearyl alcohols, in formulations of hair conditioners and shampoos. The cationic surfactant concentration in conditioners is generally of the order of 1–2% and the alcohol concentrations are usually equal to or greater than those of the cationic surfactants. The ternary system, surfactant/fatty alcohol/water, leads to a lamellar structure forming a percolated network giving rise to a gel.

It gives conditioning properties to shampoos and after-shampoo hair care products. The effects of the cationic charge density, guar concentration in aqueous solution, and treatment time on bleached European hair have been studied. A mechanical testing method has been successfully applied to determine the efficacy of cationic guars to improve the ease of combing. The results were confirmed in a shampoo formulation on both virgin and bleached hair.

Shampoo Hair care product

Shampoo is a hair care product, typically in the form of a viscous liquid, that is used for cleaning hair. Less commonly, shampoo is available in bar form, like a bar of soap. Shampoo is used by applying it to wet hair, massaging the product into the scalp, and then rinsing it out. Some users may follow a shampooing with the use of hair conditioner.

Polymers with the ability to kill or inhibit the growth of microorganisms such as bacteria, fungi, or viruses are classified as antimicrobial agents. This class of polymers consists of natural polymers with inherent antimicrobial activity and polymers modified to exhibit antimicrobial activity. Polymers are generally nonvolatile, chemically stable, and can be chemically and physically modified to display desired characteristics and antimicrobial activity. Antimicrobial polymers are a prime candidate for use in the food industry to prevent bacterial contamination and in water sanitation to inhibit the growth of microorganisms in drinking water.
