Norbornanediamine/Resorcinol Diglycidyl Ether Crosspolymer, also known by its more technical name Bicyclo[2.2.1]heptanedimethanamine, polymer with 2,2′-[1,3-phenylenebis(oxymethylene)]bis[oxirane], is a synthetic polymer used primarily in the cosmetic industry.
The ingredient is a result of advanced polymer chemistry, combining norbornanediamine and resorcinol diglycidyl ether. Norbornanediamine is a bicyclic amine, while resorcinol diglycidyl ether is an epoxy compound. When these two components undergo a polymerization reaction, they form a crosslinked network that is highly effective at creating films on the skin or hair.
Historically, the use of such polymers in cosmetics has evolved with advancements in material science. Initially, simpler film-forming agents were used, but as the demand for more sophisticated and multifunctional ingredients grew, chemists began to develop more complex polymers like Norbornanediamine/Resorcinol Diglycidyl Ether Crosspolymer. This ingredient has been incorporated into various cosmetic formulations to provide long-lasting, flexible films that enhance the performance and durability of the product.
The manufacturing process involves a controlled chemical reaction where norbornanediamine and resorcinol diglycidyl ether are combined under specific conditions to form the crosspolymer. This process ensures that the resulting polymer has the desired properties, such as film-forming ability, stability, and safety for use in cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Norbornanediamine/Resorcinol Diglycidyl Ether Crosspolymer:
One of the primary benefits of Norbornanediamine/Resorcinol Diglycidyl Ether Crosspolymer is its ability to form a film on the skin or hair. This means that when applied, it creates a thin, continuous layer that can help protect the skin or hair from environmental factors. For instance, in skincare products, this film can act as a barrier against pollutants and other external aggressors, helping to maintain the skin’s integrity and health. In hair care products, it can provide a protective coating that shields the hair from damage caused by styling tools or harsh weather conditions.
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).
When considering the use of Norbornanediamine/Resorcinol Diglycidyl Ether Crosspolymer in cosmetic products, it is important to be aware of its safety, suitability, and allergenic potential.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of this particular ingredient 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.
Side effects and adverse reactions from this ingredient are generally uncommon. However, as with any cosmetic ingredient, individual reactions can vary. It is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Norbornanediamine/Resorcinol Diglycidyl Ether Crosspolymer has a rating of 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating indicates that it is unlikely to clog pores and is generally suitable for individuals prone to acne, blemishes, or breakouts.
