Basic Info

Isododecane (CAS Registry Number: 31807-55-3 / 13475-82-6), chemically defined as a highly branched C12 isoparaffinic hydrocarbon mixture, is a clear, odorless, and colorless liquid recognized for its fast-evaporating profile and low surface tension. Consisting predominantly of 2,2,4,6,6-pentamethylheptane isomers, it delivers a dry, non-greasy skin feel and smooth glide without leaving heavy oily residues.
 
At Shandong Zhishang Chem Co., Ltd., our Isododecane is processed using high-pressure catalytic hydrogenation and fractional distillation systems to reach an isoparaffin purity of 99.0% minimum. It functions as an essential volatile carrier, weightless emollient, film-forming solvent, and non-silicone hydrocarbon vehicle across long-wearing color cosmetics, hair serums, sun care formulations, and specialized industrial coatings.

Product Packaging

Isododecane offers a versatile performance profile that makes it valuable across diverse personal care and technical sectors:
 
Long-Wear & Waterproof Color Cosmetics: Serves as the primary solvent vehicle in liquid lipsticks, waterproof mascaras, foundations, and eye liners, evaporating completely to leave a uniform, transfer-resistant polymer film.
 
Silicone-Free Hair & Skin Care: Functions as a weightless, non-greasy emollient in hair serums, dry body oils, and facial cleansers, serving as an effective replacement for volatile cyclomethicones.
 
Sun Care & Deodorants: Enhances pigment dispersion, fast-drying properties, and smooth application in spray sunscreens, antiperspirants, and body mists.
 
Industrial & Specialty Solvents: Acts as a high-purity, low-surface-tension carrier in specialty wax polishes, electronic cleaning fluids, and organometallic chemical reactions.

FAQ

A1: Isododecane delivers equivalent volatility, low surface tension, and a weightless skin feel, but belongs to the hydrocarbon chemical family. This enables formulators to create silicone-free, COSMOS-aligned products while navigating regional regulatory constraints on cyclic siloxanes.

A2: Isododecane dissolves film-forming resins such as trimethylsiloxysilicate effortlessly. Upon application, Isododecane evaporates steadily, leaving a smooth, lightweight, matte, and transfer-resistant layer on the skin or lips.

A3: Isododecane has a flash point of approximately 45 to 48 degrees C, placing it under Class 3 flammable liquids (UN 2286, PG III). Shandong Zhishang Chem provides UN-rated steel drums and IBC totes complete with dangerous goods shipping documentation.

A4: Isododecane is supplied in 150 kg iron drums, 750 kg IBC totes, and ISO tanks. Batch-specific Certificates of Analysis, Safety Data Sheets, and custom laboratory samples are provided upon request.

Quality Management & International Certifications

To comply with strict personal care regulations and international chemical shipping standards, Shandong Zhishang Chem implements comprehensive quality control frameworks:
 
ISO 9001:2015 Quality Management System: Strict process oversight covering raw material hydrogenation, fractional column distillation, quality testing, and drum packaging.
 
EU REACH Registration Compliance: Full technical documentation dossiers available to support European cosmetics importers and specialty chemical distributors.
 
Cosmetic GMP & Clean Beauty Alignment: Produced under Good Manufacturing Practices, free of aromatic solvents, heavy metals, and restricted secondary amine impurities.
 
Global Inventory Approvals: Listed on US TSCA, Canadian DSL, Chinese IECSC, and compliant with COSMOS non-silicone carrier guidelines.
Maintaining an odor-free profile, zero aromatic contamination, and tight distillation ranges is crucial for high-performance cosmetics. Every production lot of Isododecane undergoes four internal quality validation steps before Certificate of Analysis issuance:
 
Gas Chromatography Purity Assay (GC-FID): Quantifies C12 isoparaffin purity at or above 99.0% while confirming aromatic impurities remain below 10 ppm.
 
Distillation Profile Verification (ASTM D86): Monitors initial boiling point and dry point to guarantee predictable evaporation rates for color cosmetic film formation.
 
Karl Fischer Trace Moisture Determination: Maintains water content strictly below 100 ppm to ensure formula stability and prevent phase separation in anhydrated gels.
 
Color and Odor Inspection: Saybolt color testing at or above +30 paired with sensory organoleptic testing to ensure complete cosmetic elegance.
