Dioctadecyl Dimethyl Ammonium Chloride-CAS 107-64-2
Cosmetic-grade Dioctadecyl Dimethyl Ammonium Chloride (DODAC) is a high-purity long-chain quaternary ammonium cationic surfactant specially refined for daily chemical and personal care systems. With dual octadecyl long-chain structure, it has stronger lipophilicity, excellent film-forming, softening and antistatic properties compared with conventional short-chain quaternary ammonium salts, and is a core high-efficiency conditioning auxiliary for hair and skin care formulas.
In hair care products, DODAC can firmly adsorb on the hair cuticle, form a smooth and dense protective film, effectively reduce hair friction coefficient, improve dry and wet combing performance, thoroughly solve hair dryness, frizzy, knotted and static flyaway problems, and endow hair with lasting softness, smoothness and luster.
It has excellent softening and finishing effects on fiber fabrics, which can significantly improve fabric fluffy and soft feeling, eliminate static adhesion, and is widely used in daily fabric softening formulas. In addition, this product has good emulsifying, dispersing and flocculating purification capabilities, which can stabilize oil-water dispersion systems and adsorb suspended impurities in water, assisting in formula purification and system stabilization.
With low irritation, stable chemical properties and no peculiar smell, it is compatible with cationic and nonionic surfactants without reaction and deactivation, and is a multi-functional high-value auxiliary widely used in high-end conditioning and softening daily chemical products.
Key Benefits
• Superior Hair Conditioning & Smoothing: Long-chain lipophilic structure adheres tightly to hair cuticles, repairs dry and frizzy hair, reduces combing resistance, and creates long-lasting silky smooth hair texture.
• Powerful Antistatic Performance: Effectively neutralize static charges on hair and fabric surfaces, eliminate static flyaway and adhesion problems, and maintain stable and fluffy texture.
• Excellent Softening & Fluffing Effect: Significantly improve the softness and ductility of hair and fiber fabrics, relieve dry and hard texture, and upgrade the delicate and fluffy touch of finished products.
• Multi-Functional Emulsification & Purification: Integrates emulsification, dispersion and flocculation functions, stabilizes oil-water system, adsorbs suspended impurities, and optimizes formula clarity and stability.
• Mild & Safe High Compatibility: Low irritation to skin and hair, no peculiar smell, stable performance, perfectly compatible with cationic and nonionic formula systems, no inactivation or precipitation.
• High Purity & Cost-Effective: Cosmetic high-purity refined grade, low impurity content, low dosage and obvious effect, suitable for mass production of high-end conditioning daily chemicals.
Applications
• Professional Hair Care Products: Widely used in hair conditioner, hair mask, hair care essence, smoothing shampoo and hair care spray, improve hair smoothness, softness and anti-static ability, repair damaged hair quality.
• Daily Fabric Softening Products: The core raw material of clothing softener, fabric finishing agent and textile care products, soften fiber fabrics, eliminate static electricity, and maintain fluffy and soft clothing feel.
• Skin Care & Body Care Formulas: Applied in body lotion, body cream and mild care products, assist in moisturizing and smoothing skin, improve skin ductility and delicate touch.
• Daily Chemical Emulsification System: Served as cationic emulsifier and dispersant in oil-water separation formulas, stabilize system uniformity, prevent layering and precipitation, and improve formula durability.
• Water Purification & Flocculation Formulas: Used in daily chemical water treatment and formula purification, adsorb suspended particles, purify water quality, and optimize finished product clarity.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of cosmetic grade DODAC?
A1: The standard MOQ is 1KG, and sample orders are supported for formula testing and stability trial production.
• Q2: What certification documents can be provided?
A2: Complete COA, MSDS and full set of global customs clearance documents are available to support export declaration.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Conventional addition ratio is 0.3%-1.0% for hair care products, 0.2%-0.8% for fabric softeners, adjustable according to conditioning and softening effect requirements.
• Q4: What is the core advantage of DODAC compared with ordinary quaternary ammonium salts?
A4: DODAC has double long-chain structure, stronger lipophilicity, better film-forming, smoothing and antistatic effects, more durable conditioning effect, less irritation, and is not easy to cause hair dryness and hardening.
• Q5: What formula compatibility taboos should be noted?
A5: It is forbidden to mix and use with anionic surfactants, which will cause flocculation and inactivation. It is perfectly compatible with cationic and nonionic surfactant systems.
• Q6: Do you support stable large-batch supply all year round?
A6: Sufficient factory production capacity ensures continuous, stable and large-volume supply throughout the year to support long-term cooperative orders and customized formula demands.
