Cocamide DEA (Ninol/6501 type, CAS: 68603-42-9) produced by Guoli Chemical is a nonionic surfactant synthesized from natural coconut oil. Its core active ingredient is coco fatty acid diethanolamide — an alkanolamide mixture formed by the condensation of coconut oil fatty acids with diethanolamine at a 1:1 molar ratio. The general molecular formula can be expressed as RCON(CH₂CH₂OH)₂, where R represents the mixed fatty acid alkyl chains derived from coconut oil (mainly including mixed chains of caprylic acid C8, capric acid C10, lauric acid C12, myristic acid C14, palmitic acid C16, and oleic acid C18:1, etc.), and the active matter content is strictly controlled at 78.0%~82.0%.
In addition to the main component, the product inevitably contains small amounts of by-products and unreacted raw materials: free diethanolamine content is controlled below 5%, free alcohols (including glycerol, unreacted diols, etc.) not exceeding 2%, tertiary amine content not exceeding 2%, and water not exceeding 1.0%. The product is a light yellow to amber transparent viscous liquid with a density of 1.01~1.05 (25°C) and a freezing point below 10°C. It has good chemical stability under normal storage conditions.
This product is a typical 1:1 type alkanolamide (distinguished from the 2:1 type 6502), with an HLB value of about 3.6~5.8. It has excellent water solubility and outstanding thickening, foam stabilizing, emulsifying, and detergency properties. Its amine value ranges from 120~160 mgKOH/g, and hydroxyl value ranges from 220~280 mgKOH/g. These indicators directly reflect the degree of amidation and active matter purity, and are important criteria for judging product quality.

The core component of this product, coco fatty acid diethanolamide, determines its excellent application performance: in personal care products (shampoos, body washes), it is used for its thickening and foam stabilizing properties, with a recommended dosage of 1%~5%; in liquid detergents (dishwashing liquids, laundry detergents), it serves as a detergency booster, with a recommended dosage of 2%~8%; in textiles, metalworking, and pesticide formulations, it acts as an emulsifying and dispersing component, with dosage adjusted according to specific processes. Due to its slight alkalinity (pH 8.5~10.5 for a 1% aqueous solution), compatibility with acidic components must be considered in the formulation.
