Polyquaternium-28, also known by its chemical name 1-Propanaminium, N, N, N-trimethyl-3-((2-methyl-1-oxo-2-propenyl)amino)-, chloride, polymer with 1-ethenyl-2-pyrrolidinone, is a synthetic polymer commonly used in cosmetic products. This ingredient is part of the polyquaternium family, a group of polymers known for their conditioning and antistatic properties. Polyquaternium-28 is specifically designed to provide film-forming benefits, making it a popular choice in hair care and skincare formulations.
The history of Polyquaternium-28 in cosmetics dates back to the mid-20th century when the demand for more effective and versatile conditioning agents led to the development of synthetic polymers. Researchers discovered that by combining certain monomers, they could create a polymer that not only conditioned hair but also reduced static electricity and formed a protective film on the skin and hair. This innovation quickly found its way into various cosmetic products, from shampoos and conditioners to lotions and creams.
Polyquaternium-28 is made through a polymerization process that involves the reaction of 1-Propanaminium, N, N, N-trimethyl-3-((2-methyl-1-oxo-2-propenyl)amino)-, chloride with 1-ethenyl-2-pyrrolidinone. This chemical reaction results in a long-chain polymer that possesses the desired antistatic and film-forming properties. The production process is carefully controlled to ensure the consistency and safety of the final product, making it suitable for use in a wide range of cosmetic applications.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyquaternium-28:
One of the primary benefits of Polyquaternium-28 is its antistatic property. This means it helps to reduce static electricity, which can be a common issue in hair care products. Static electricity can cause hair to become frizzy, flyaway, and difficult to manage. By incorporating Polyquaternium-28 into formulations, products can help keep hair smooth, manageable, and free from static cling. This is especially beneficial in dry or winter conditions when static electricity tends to be more problematic.
Polyquaternium-28 is also recognized for its film-forming capabilities. This means it can create a thin, continuous layer over the surface where it is applied. In hair care products, this film can help to lock in moisture, protect the hair from environmental damage, and enhance the overall appearance by providing a smooth, glossy finish. In skincare products, the film-forming property can help to create a barrier that protects the skin from external irritants and helps to retain moisture, leading to a hydrated and healthy-looking complexion.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Polyquaternium-28 is generally considered safe for use in cosmetic products, but like any ingredient, it may cause side effects in some individuals. Here are some potential side effects of topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polyquaternium-28 during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Polyquaternium-28 are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to perform a patch test before widespread usage.
Polyquaternium-28 has a comedogenicity rating of 0, meaning it is considered non-comedogenic. This makes it a suitable ingredient for individuals prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
