Question 1

Is Cocamide DEA/CDEA6501-92% (Ninol) harmful to humans? Does it affect the environment?

Accepted Answer

Cocamide DEA/CDEA6501-92% (Ninol) has clear irritant and potential carcinogenic risks to humans, and also poses certain ecotoxicity to aquatic environments, requiring standardized use under strict protective conditions. Detailed Explanation The main health risks of Cocamide DEA (Ninol) to humans are reflected in three aspects: skin irritation (GHS Category 2, H315), serious eye irritation (GHS Category 2, H319), and potential carcinogenicity (GHS Category 2, H351). The International Agency for Research on Cancer (IARC) classifies it as Group 2B — "possibly carcinogenic to humans," mainly due to residual diethanolamine (DEA) in the product. DEA can react with nitrosating agents under specific conditions to form nitrosamines, which are known carcinogenic precursors. At normal use concentrations (e.g., typically added at 1%-3% in shampoos and shower gels), its irritancy is greatly reduced by dilution, but direct contact with the concentrated product can still cause significant skin and eye discomfort. In terms of the environment, Cocamide DEA is a moderately biodegradable nonionic surctant. Although its basic structure is derived from natural coconut oil, the diethanolamide group makes its degradation rate in the natural environment slower than that of fully natural tty acid derivatives. If leaked into water bodies, the surctant effect reduces the surce tension of water, affecting fish gill respiration and aquatic microbial communities. This product has certain acute toxicity to aquatic organisms (fish 96h-LC50 is typically in the range of 1-10 mg/L), and may produce persistent foam in water bodies, affecting reoxygenation and the normal function of aquatic ecosystems. Therefore, untreated wastewater containing this product must not be discharged directly into natural water bodies. Overall, under conditions of compliant use and proper disposal, the actual risks of Cocamide DEA to humans and the environment are within a controllable range. Decades of widespread use in the global daily chemical industry have also proven its safety in finished products. However, during production, transportation, and handling of concentrated products, safety regulations must be strictly followed, personal protective equipment must be worn, and wastewater must be treated to meet standards before discharge.

After work, thoroughly wash exposed areas (P264). Ventilation requirements: Keep the workplace well-ventilated and install local exhaust ventilation if necessary. Formula control: In end-use consumer products (shampoos, shower gels, etc.), the recommended addition amount is controlled at 1%-5%, so that after dilution, it does not cause significant skin irritation. Nitrosamine prevention: Avoid coexistence with nitrosating agents (such as certain preservatives like nitrites) in the formula, control the residual DEA content in raw materials, and consider adding antioxidants like tocopherols to inhibit nitrosamine formation. Wastewater treatment: Industrial wastewater containing this product must be treated through a biological treatment system (activated sludge process) to meet standards before discharge. It is strictly prohibited to discharge directly into rivers or soil without treatment. Storage conditions: Store in a cool, well-ventilated place in sealed containers, keep temperature at 10–40°C, and keep away from strong oxidizers and strong acids. Precautions If in eyes: Rinse cautiously with plenty of flowing water for at least 15 minutes and seek medical attention (P305+P351+P338). If on skin: Immediately remove contaminated clothing, wash thoroughly with soap and water (P302+P352). In case of spillage: Use sand, vermiculite or other inert materials to absorb and collect, dispose of as hazardous waste, do not flush into drains. This product is combustible but not flammable. In case of fire, use dry powder, carbon dioxide, water fog. Firefighters must wear self-contained breathing apparatus. Pregnant and lactating women should avoid direct contact with concentrated products. Use in finished products must comply with relevant cosmetic regulations on DEA residue limits.

Question 8

How to use Cocamide DEA/CDEA6501-92% (Ninol)? What is the recommended dosage?

Accepted Answer

Cocamide DEA/CDEA6501-92% (Ninol) is a highly efficient nonionic surctant, recommended for use as a thickener, foam stabilizer, and co-emulsifier in formulations. The typical addition amount is 1%–10% of the total formula weight, and the specific dosage should be optimized through experiments based on the system type and performance targets. Detailed Description Cocamide DEA (Ninol) is a high-activity nonionic surctant (active matter ≥92%) produced by Guoli Chemical through condensation of coconut oil with diethanolamine. It has an HLB value of approximately 6–7, appears as a light yellow to amber transparent viscous liquid, is readily soluble in water, and has a cloud point of 80–90°C. It exhibits excellent compatibility with anionic, cationic, and amphoteric surctants. Its core function is to achieve comprehensive effects of thickening, foam stabilization, emulsification, dispersion, and anti-redeposition in liquid cleaning formulations, making it a key auxiliary agent for building high-quality daily chemical cleaning products and industrial cleaning products. In practical use, cocamide DEA significantly amplifies the thickening effect in the presence of salt (such as sodium chloride), so it is widely used in products requiring viscosity control such as shampoos, body washes, and dishwashing detergents. At the same time, it effectively enhances the foam richness and persistence of anionic main surctants (such as AES, LAS), making the foam finer and more stable, and reduces the degreasing irritation of the main surctant on the skin, giving the skin a non-tight, soft touch after washing. This product contains trace free diethanolamine, and the formulation pH is weakly alkaline (1% aqueous solution pH 9.0–11.0). Personal protection should be taken during operation. Storage requires the container to be sealed and stored in a cool, ventilated place at 10–40°C, avoiding coexistence with strong oxidizers and nitrite substances to prevent the formation of potentially carcinogenic N-nitroso compounds. Usage Method and Processing Recommendations Dosing Method: This product is a viscous liquid (kinematic viscosity 400–800 mPa·s at 25°C). Viscosity increases significantly in low-temperature seasons. It is recommended to preheat it at 25–40°C before dosing to cilitate pumping and dispersion. The addition sequence should be after the main surctant is fully dissolved, usually mixed and stirred evenly with anionic surctants (such as AES, LAS) and water. If inorganic salt thickener (sodium chloride) needs to be added, it should be added stepwise after cocamide DEA has been added and stirred evenly, to avoid local high concentration leading to precipitation or gelation. In systems containing amphoteric surctants such as betaine, cocamide DEA can synergize with them to further enhance viscosity and foam performance. Shear and Temperature Control: Stirring speed should not be too high; medium-low speed stirring (100–300 rpm) is recommended to avoid introducing too many bubbles. Heating temperature should not exceed 70°C to avoid amide decomposition or color deepening due to prolonged high temperature. If the formulation contains heat-sensitive components such as fragrance and preservatives, they should be added after the system has cooled below 45°C. Recommended Dosage (Reference Amount) The following are typical recommended dosage ranges for different application areas (based on total formula weight). Actual addition amounts should be confirmed through experiments according to the specific formulation system, target viscosity, and foam performance: Application Area Recommended Dosage (wt%) Main Function Shampoo / Body Wash / Hand Soap 1.5 – 4.0% Thickening, foam stabilization, reducing irritation, imparting smooth skin feel cial Foam / cial Cleanser 1.0 – 3.0% Building dense elastic foam, gentle cleansing, moisturizing Dishwashing Detergent (Dish Soap) 2.0 – 5.0% Thickening, stabilizing foam, enhancing degreasing power Hard Surce Cleaner 1.0 – 3.0% Thickening carrier, extending contact time, enhancing descaling efficiency Industrial Degreaser/Detting Agent 3.0 – 8.0% Emulsifying dispersion, penetrating and stripping heavy oil Textile Scouring Agent / Penetrant 2.0 – 6.0% Wetting and penetrating, removing fiber waxy impurities Leather Degreasing Agent 2.0 – 5.0% Emulsifying and removing natural oils from raw hides Metalworking Fluid (Cutting/Grinding Fluid) 1.0 – 3.0% Emulsifying lubrication, rust prevention, foam suppression Note: The above dosage ranges are industry empirical reference values. Guoli Chemical's product database does not yet have precise recommended dosage parameters for this product. The specific formulation ratio should be determined through laboratory small-scale tests and pilot validation. Application Recommendations Thickening System Optimization: In daily chemical formulations containing AES/LAS, adding 2%–3% cocamide DEA combined with 0.5%–1.5% sodium chloride usually achieves ideal rheological curves and transparency. It is recommended to add salt in portions to avoid sudden viscosity drop (salting-out effect) due to excess. Foam Performance Improvement: For shampoos and body washes pursuing rich and fine foam, combining cocamide DEA with cocamidopropyl betaine (CAB) can significantly improve foam texture and rinsing smoothness while thickening. A typical combination ratio is main surctant:6501:CAB = 10–15:2–3:3–5. Industrial Formulation Notes: In high-alkali or high-electrolyte systems, the main surctant should be pre-dissolved before adding this product to ensure full dispersion and avoid local flocculation. If combined with other nonionic surctants (such as AEO series), the complementary HLB values can be utilized to adjust the emulsifying capacity of the system. Precautions

When used in salt-containing systems, the thickening effect is particularly prominent, effectively reducing the need for additional thickeners and lowering formulation costs. Priority of Recommended Applications: As a preferred thickener and foam stabilizer in personal care formulations like shampoo and shower gel; as a secondary surctant to enhance viscosity and grease removal in dishwashing detergents and hard surce cleaners; as an emulsifying dispersant in industrial degreasers, working synergistically with other primary surctants. In textile and leather processing fields, it is recommended to use as a component of auxiliary formulations, with specific dosage determined by experiments based on process requirements. Dosage Reference: According to the product database of Guoli Chemical, there is no standard value for recommended dosage. It is suggested that users determine the optimal addition ratio through experiments based on the target formulation system. Generally, in liquid detergent formulations, an addition range of 1%~5% can achieve significant thickening and foam stabilization effects.
