Polybutene (Polybutene) is a versatile hydrocarbon-based polymer known for its moderate-low molecular weight and medium viscosity, making it an effective thickener in cosmetic formulations. This multifunctional ingredient not only enhances gloss and provides viscosity control but also serves as an emollient, solubilizer, dispersant, and stabilizing agent. Its unique properties contribute to improved texture and performance in various products, ensuring that formulations maintain stability while delivering a luxurious feel. Keep in mind that due to its composition, Polybutene is classified as HazMat for shipping purposes, highlighting the importance of handling it with care.
