Description

Oligopeptide P11-4 CAS NO 593266-60-5 is a synthetic, biomimetic peptide specifically designed to promote the remineralization of dental enamel. This compound matters because it offers a targeted, non-invasive approach to early caries management by forming a scaffold that guides the deposition of hydroxyapatite crystals. It is primarily needed by manufacturers in the oral care and dental industries for formulating advanced toothpaste, mouthwash, and professional dental treatments.

Application

• Advanced Toothpaste Formulations: As a key active ingredient for enamel repair and sensitivity relief.
• Therapeutic Mouthwashes: For daily-use products targeting early-stage tooth decay (white spot lesions).
• Professional Dental Products: Including gels, varnishes, and creams used in dental clinics for preventive care.
• Sensitive Teeth Products: To help occlude dentinal tubules and reduce hypersensitivity.
• Cosmetic Dentistry: In products aimed at improving enamel luster and surface smoothness.
• Chewing Gum and Lozenges: For extended oral contact and sustained remineralization benefits.
• Biomaterial Research: As a model compound for studying peptide-guided biomineralization processes.
