Nylon-12, also known by its chemical name Azacyclotridecan-2-one, homopolymer, is a versatile synthetic polymer widely used in the cosmetic industry. This ingredient is part of the nylon family, which is a group of synthetic polymers known for their durability and flexibility. Nylon-12 is specifically appreciated for its fine particle size and smooth texture, making it a popular choice in various skincare and makeup products.
The history of Nylon-12 dates back to the mid-20th century when it was first developed as part of the broader category of nylon polymers. Initially used in industrial applications due to its strength and resilience, it didn’t take long for the cosmetic industry to recognize its potential. Over the years, Nylon-12 has become a staple in many cosmetic formulations, particularly in products that benefit from its bulking, opacifying, and viscosity-controlling properties.
Nylon-12 is synthesized through a polymerization process involving the monomer laurolactam. This process creates a homopolymer, which is a polymer consisting of identical monomer units. The resulting material is then processed into fine powders or microspheres, which can be easily incorporated into various cosmetic formulations. This manufacturing process ensures that Nylon-12 maintains its desirable characteristics, such as its ability to provide a silky, smooth feel and improve the overall texture of cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Nylon-12:
Nylon-12 is often used as a bulking agent in cosmetic formulations. This means it helps to increase the volume of a product without significantly altering its other properties. For instance, in powders and foundations, Nylon-12 can add a lightweight, airy texture, making the product feel more substantial and luxurious on the skin. This can also help in achieving a smoother application and a more even finish.
As an opacifying agent, Nylon-12 plays a crucial role in making cosmetic products less transparent or opaque. This is particularly useful in products like foundations, concealers, and certain skincare items where a more opaque finish is desired. By reducing transparency, Nylon-12 helps to mask skin imperfections and provides a more uniform appearance, enhancing the overall aesthetic appeal of the product.
Nylon-12 is also employed as a viscosity controlling agent. This means it helps to adjust the thickness or thinness of a cosmetic product. In creams, lotions, and gels, controlling viscosity is essential for ensuring the product spreads easily and evenly on the skin. Nylon-12 can help achieve the perfect consistency, making the product more user-friendly and effective in its application.
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).
Nylon-12 is generally considered safe for use in cosmetics and personal care products. It is non-toxic and non-irritating, making it suitable for a wide range of skin types. However, as with any 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 Nylon-12 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 Nylon-12 are relatively uncommon, but it is always a good practice to conduct a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
In terms of comedogenicity, Nylon-12 has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that Nylon-12 is unlikely to clog pores, making it a suitable option for individuals prone to acne, blemishes, or breakouts.
