Vinyl Chloride/Vinyl Laurate Copolymer, also known by its chemical name Poly(vinyl chloride-co-vinyl laurate), is a synthetic polymer used primarily in the cosmetic industry for its film-forming properties. This ingredient is a copolymer, which means it is made from two different monomers: vinyl chloride and vinyl laurate. When combined, these monomers create a versatile compound that can form a flexible, durable film on the skin or hair.
The history of Vinyl Chloride/Vinyl Laurate Copolymer in cosmetics dates back to the mid-20th century when synthetic polymers began to gain popularity for their unique properties and versatility. Initially used in industrial applications, the copolymer’s ability to form a continuous film made it an attractive option for cosmetic formulations, particularly in products like hairsprays, mascaras, and nail polishes.
The production of Vinyl Chloride/Vinyl Laurate Copolymer involves a chemical process called copolymerization. In this process, vinyl chloride and vinyl laurate monomers are combined in the presence of a catalyst, which initiates a reaction that links the monomers together to form a long-chain polymer. The resulting copolymer is then purified and processed into a form that can be easily incorporated into various cosmetic products.
While the copolymer is primarily known for its film-forming capabilities, it is important to understand what it can and cannot do. It excels at creating a smooth, even layer that can help protect and enhance the appearance of the skin or hair. However, it does not provide moisturizing benefits or active skincare properties, so it is often used in conjunction with other ingredients that offer these functions.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Vinyl Chloride/Vinyl Laurate Copolymer:
One of the primary benefits of Vinyl Chloride/Vinyl Laurate Copolymer is its film-forming capability. This means that when applied to the skin or hair, it creates a continuous, cohesive layer. This film can serve multiple purposes in cosmetic formulations:
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).
Vinyl Chloride/Vinyl Laurate Copolymer is generally considered safe for use in cosmetics, with a low potential for causing allergic reactions. However, as with any cosmetic ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Vinyl Chloride/Vinyl Laurate Copolymer during pregnancy are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice.
Adverse reactions to this ingredient are relatively uncommon, but it is always prudent to perform a patch test before widespread usage to ensure personal compatibility.
In terms of comedogenicity, Vinyl Chloride/Vinyl Laurate Copolymer is rated at a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means it is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
