Dimethyl Urea

Product Description

Green Stone Swiss supplies cosmetic-grade Dimethyl Urea under a direct factory model, with GMP-aligned quality control, batch documentation, and sample support for brands developing professional nail-care systems.

Dimethyl Urea (1,3-dimethylurea; C₃H₈N₂O; CAS 96-31-1) is a urea derivative listed in CosIng with a nail-conditioning function. In nail hardeners and treatments it is used to support controlled keratin cross-linking in the nail plate, helping improve apparent hardness and flexibility versus overly aggressive formaldehyde-type approaches.

It is typically specified for nail hardeners, base coats, and leave-on nail conditioners where formulators need a water-soluble, documentable conditioning active rather than a face-serum humectant hero.

Key Benefits & Applications

Dimethyl Urea is a high-purity nail-conditioning ingredient for professional hardeners, base coats, and nail-treatment formulas.

• Supports CosIng nail-conditioning performance in leave-on nail-care systems
• Used to promote controlled keratin cross-linking for firmer, less brittle-feeling nail plates
• Suitable for nail hardeners, ridge fillers, base coats, and cuticle-adjacent treatments
• Water-soluble profile supports aqueous and solvent-compatible nail chassis
• Typical use level: Formulation-dependent; finalize by product type and regional assessment

Formulation Guidelines

Use these notes to incorporate Dimethyl Urea into stable nail-conditioning and hardener systems.

• Suggested Use Level: Formulation-dependent; confirm in finished-product testing and regional compliance review
• Addition: Dissolve in the aqueous or compatible solvent phase with moderate stirring; avoid unnecessary prolonged high heat
• pH Range: Adjust and buffer to common cosmetic pH targets for the chassis; verify clarity, drying, and film feel
• Compatibility: Screen with resins, plasticizers, pigments, and film formers used in nail systems; confirm adhesion and flexibility in the final lacquer or treatment
• Stability: Keep bulk dry and sealed; protect finished goods from humidity where practical
• Combine with Hydroxypropyltrimonium Hydrolyzed Keratin for keratin-focused nail and cuticle-conditioning systems.
