THE STORY OF DIMETHYL ISOSORBIDE
Dimethyl Isosorbide: The High-Performance Delivery Solvent for Modern Cosmetics
Dimethyl Isosorbide (DMI) is an advanced solvent and penetration enhancer widely used in skincare, haircare, and pharmaceutical formulations. Known for its ability to deliver actives deeper and more efficiently, DMI improves the performance of ingredients like retinol, salicylic acid, glycolic acid, niacinamide, ferulic acid, and peptides — making formulations more effective and stable.
Eco-Derived Dimethyl Glucose Ester Engineered for Efficient Delivery
Dimethyl Isosorbide is synthesized from isosorbide, a renewable sugar-derived molecule obtained from sorbitol (corn/cane sugar).
Its molecular structure allows it to:
• Dissolve poorly soluble actives
• Enhance stability of sensitive ingredients
• Improve dermal penetration without irritation
TRCkem supplies cosmetic- and pharmaceutical-grade DMI with high purity for advanced formulations.
Boost. Deliver. Stabilize.
Key functional benefits:
✅ Enhances dermal penetration of active ingredients
✅ Boosts performance of acids (AHA/BHA) & retinoids
✅ Stabilizes volatile/oxidation-prone actives
✅ Improves solubility of poorly soluble compounds
✅ Reduces irritation by enabling lower dosage of strong actives
Used in: retinol serums, brightening boosters, exfoliating solutions, anti-aging creams, transdermal patches, scalp serums, and clear gel systems.
Safe, Stable & Versatile — Ideal for High-Active Formulations
• Typical use level: 1–10% (up to 20% for high-active systems)
• Mixable with water, alcohols, glycols, and many oils
• Ideal for serums, gels, hair tonics, and chemical exfoliants
• Enhances stability of actives like:
– Retinol, Resveratrol
– Salicylic Acid / Lactic Acid
– Vitamin C Esters
• Low irritation, non-sensitizing, and globally approved
• Store in cool, dry conditions — highly stable & non-reactive
Formulator’s Queries, We Answered
1. What is Dimethyl Isosorbide?
Dimethyl Isosorbide (DMI) is a highly pure, clear, and stable solvent derived from sorbitol (a sugar alcohol). It is widely used in the personal care and cosmetic industry as a carrier agent to enhance the delivery and penetration of active ingredients into the skin.
2. What is the CAS number and INCI name of Dimethyl Isosorbide?
CAS Number: 5306-85-4
INCI Name: Dimethyl Isosorbide
3. What are the main benefits of using Dimethyl Isosorbide in cosmetic formulations?
Enhanced delivery: Improves the absorption and bioavailability of active ingredients like vitamins, peptides, and botanical extracts.
Solubilization: Helps dissolve poorly soluble ingredients, making formulations more stable.
Stability booster: Enhances the chemical stability of sensitive actives.
Skin feel improvement: Provides a light, non-greasy, and pleasant sensory profile.
4. In what types of personal care products is Dimethyl Isosorbide commonly used?
Dimethyl Isosorbide is used in a wide range of products, including:
Anti-aging creams and serums
Acne treatments
Skin-brightening products
Scalp and hair care solutions
