Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer is a synthetic polymer used in various cosmetic formulations. This ingredient is also known by other names such as Poly(norbornene-co-tris(trimethylsiloxy)silylnorbornene). It is a copolymer, meaning it is composed of two different monomers: norbornene and tris(trimethylsiloxy)silylnorbornene. These monomers are chemically bonded to create a larger, more complex molecule that exhibits unique properties beneficial for cosmetic applications.
The history of Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer in cosmetics is relatively recent, emerging from advancements in polymer chemistry and material science. Initially developed for industrial applications due to its robust film-forming capabilities and stability, it soon found its way into the cosmetic industry. Researchers discovered that its unique chemical structure could provide desirable properties such as forming a flexible, durable film on the skin or hair, and controlling the viscosity of cosmetic products.
The production of this copolymer involves a polymerization process where norbornene and tris(trimethylsiloxy)silylnorbornene monomers are chemically reacted in the presence of a catalyst. This process results in a long-chain polymer that combines the beneficial properties of both monomers. The norbornene component contributes to the rigidity and strength of the polymer, while the tris(trimethylsiloxy)silylnorbornene part imparts flexibility and a smooth, silky texture. This combination makes the copolymer particularly useful in creating products that need to form a protective, yet breathable, film on the skin or hair.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer:
One of the primary benefits of Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer is its film-forming capability. This means that when applied to the skin or hair, it creates a thin, continuous layer. This film can help in several ways:
Another significant benefit of this copolymer is its ability to control the viscosity of cosmetic formulations. Viscosity refers to the thickness or thinness of a product. Here’s how this function is beneficial:
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).
Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer is generally considered safe for use in cosmetic products. It is designed to form a film on the skin and control viscosity, which can enhance the texture and application of the product. However, as with any cosmetic ingredient, there are potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from this ingredient are relatively uncommon. However, it is always a good practice to conduct a patch test before widespread usage to ensure that you do not have a sensitivity or allergy to the ingredient.
In terms of comedogenicity, Norbornene/Tris(Trimethylsiloxy)Silylnorbornene Copolymer is rated as a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means that it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
