The Eliva Rubber Base Gel nail in Lipstick Pink R260 is a nail product designed to provide a durable and long-lasting manicure. The chemical composition of this product includes a combination of rubber base gel, pigments for coloration, and other additives to enhance adhesion and flexibility. The rubber base gel in this product is typically composed of oligomers such as urethane acrylate or polyester acrylate, which provide a strong and flexible base for the nail polish. These oligomers are cross-linked using photoinitiators such as benzoyl peroxide or UV initiators to create a polymer network that hardens when exposed to UV light. The active ingredients in the lipstick pink coloration may include pigments such as D&C Red No. 7. These pigments are finely ground particles that impart color to the gel. Additionally, the formulation may contain additives such as plasticizers or solvents to adjust the viscosity and improve the application properties of the product. The mechanism of action of this product involves applying a thin layer of the rubber base gel onto the nail plate, followed by curing under a UV or LED lamp. The pigmented gel is then applied on top of the base layer and cured to create a glossy finish. The rubber base gel provides adhesion to the natural nail while allowing flexibility to prevent cracking or chipping.
