Dimethyl Isosorbide

Product Description

Manufactured via high-precision organic refining at our advanced direct factory, our high-purity Dimethyl Isosorbide (DMI) guarantees exceptional batch stability for premium cosmetic formulations.

As a highly substantive, sustainable polar solvent, it works through advanced molecular miscible partitioning to significantly lower the mass-transfer resistance of the stratum corneum, facilitating deep dermal penetration of co-administered hydrophilic and lipophilic actives.

Driven by the escalating market demand for high-performance anti-aging and brightening skin treatments, this innovative chemical maximizes active material bio-availability, dramatically elevating the commercial value of clinical personal care brands.

Product Specification

• Product Name: Dimethyl Isosorbide (DMI)
• Chemical Class: Cyclic Ether / Penetration Enhancer
• CAS No.: 5306-85-4
• Appearance: Clear, colorless, virtually odorless liquid
• Purity (Assay): ≥ 99.5% [Suggested]
• Solubility: Soluble in water, cosmetic glycols, ethanol, and most oils

Key Benefits & Applications

• Advanced Dermal Penetration: Dramatically intensifies the epidermal transport of active molecules like Vitamin C derivatives, Salicylic Acid, and Retinoids, optimizing their localized therapeutic bio-availability.
• Active Stabilization Matrix: Prevents the premature degradation or crystallization of challenging active compounds in aqueous solution architectures, extending product shelf life.
• Non-Irritating Vehicle: Replaces harsh industrial glycol carriers, delivering a smooth, non-greasy skin feel with superior cutaneous tolerance suitable for reactive skin lines.

Formulation Guidelines

• Recommended Usage Rate: 1.0% - 10.0% [Suggested depending on active load requirements].
• Processing Phase: Can be easily added to either the water or oil phase; displays excellent thermal stability under conventional manufacturing temperatures.
• Optimum pH Range: Highly stable across a broad pH spectrum (pH 3.0 - 8.5), making it highly versatile for acid-based peels or alkaline formulas.
• Synergy: Combine with Sodium Levulinate for a synergistic system that accelerates antimicrobial penetration through bacterial cell walls while maximizing active ingredient transdermal delivery.
