2. Physical and Chemical Properties

2.1 Appearance

• At room temperature, it typically appears as a white to light yellow flake solid. This solid form is convenient for storage and transportation, and can be easily processed into various formulations.

2.2 Melting Point

• The melting point is in the range of 65 ± 5°C. This property is crucial for applications where temperature - related processing is involved, such as melting it for blending with other liquid ingredients in the manufacturing of personal care or cleaning products.

2.3 Solubility

• It is insoluble in water. However, it can form a clear solution when combined with soap or other surfactants. This characteristic makes it suitable for formulating products that require a stable mixture of oil - soluble and water - soluble components. For example, in liquid detergents, it can help disperse oil - based stains in the water - based cleaning solution.

2.4 pH - related Property

• In a 10g/L, 10% ethanol solution, the pH value ranges from 8.0 - 10.0. This slightly alkaline nature is beneficial in certain applications, such as in soap - based products, as it can contribute to the overall pH balance and enhance the cleaning and emulsifying effects.

2.5 Other Key Chemical Properties

• It is a non - ionic surfactant, which means it does not carry an electrical charge in solution. This property gives it excellent compatibility with a wide range of other surfactants, both ionic and non - ionic. It also shows good stability across different pH levels, from acidic to moderately alkaline environments, and in the presence of hard water.

3. Product Characteristics

3.1 Emulsifying and Foaming Abilities

• Emulsification: Coconut Oil Monoethanolamide has strong emulsifying properties. It can effectively reduce the interfacial tension between oil and water phases, allowing for the formation of stable emulsions. This is highly useful in products like creams, lotions, and some types of liquid soaps, where a homogeneous mixture of oil and water is required.
• Foam Stabilization: It is an excellent foam booster and stabilizer. Even at low concentrations, it can significantly enhance the foam volume and stability in products such as shampoos, bubble baths, and liquid hand soaps. The stable foam not only improves the user experience but also aids in the cleaning process by increasing the contact time between the product and the surface to be cleaned.

3.2 Thickening Property

• It has outstanding thickening capabilities. When added to formulations containing alkyl ether sulfates, alkyl sulfates, or amphoteric surfactants, it can increase the viscosity of the product. This thickening effect is particularly valuable in liquid detergents and personal care products, as it gives the products a more desirable texture and helps in their application. For example, in a shampoo, the thickened consistency makes it easier to dispense and spread evenly on the hair.

3.3 Wetting and Detergency

• Wetting Agent: As a wetting agent, it can lower the surface tension of water, enabling better penetration and spreading of the product on various surfaces. This is beneficial in cleaning applications, as it allows the detergent to reach and surround dirt and stains more effectively.
• Detergency: It contributes to the overall detergency of cleaning products. It can help in the removal of oil - based and particulate dirt from surfaces, making it a key ingredient in solid soap, soap powder, washing powder, and liquid detergents.

3.4 Biodegradability

• It has excellent biodegradability, with a degradation rate of over 97%. This makes it an environmentally friendly choice, especially in the context of increasing concerns about the environmental impact of surfactants. When used in household and personal care products, it breaks down naturally in the environment, reducing the risk of long - term pollution.

3.5 Other Benefits

• It has good fragrance - retention properties, which means it can help hold and release the fragrance in products for a longer time. In addition, it has some anti - static properties, which can be useful in hair care products to prevent flyaways and in fabric softeners to reduce static cling in clothes.

4. Preparation Method

• Coconut Oil Monoethanolamide is typically produced by the reaction of fatty acids derived from refined, bleached, and deodorized (RBD) coconut oil with monoethanolamine. There are different reaction methods, such as the one - step and two - step processes.
• One - step Process: In the one - step process, coconut oil and monoethanolamine react directly under appropriate conditions. This method is relatively simple, but it may result in a product with lower purity due to the formation of by - products.
• Two - step Process: The two - step process usually involves an initial reaction to form an intermediate, followed by a second reaction to obtain the final product. This method can produce a product with a lighter color, a higher amide content (up to 95% or more), and better thickening and foam - stabilizing properties. The reaction conditions, including temperature, pressure, and reaction time, are carefully controlled to optimize the yield and quality of the product. After the reaction, the product may undergo purification steps such as distillation or extraction to remove impurities and unreacted starting materials.

5. Application Fields

5.1 Personal Care Products

• Shampoos: In shampoos, it acts as a thickener, foam stabilizer, and mild cleansing agent. It helps to create a rich, creamy lather that effectively cleanses the hair without stripping it of its natural oils. It also contributes to a pleasant user experience with its fragrance - retention properties.
• Bubble Baths and Liquid Soaps: It is used to enhance foam formation and stability in bubble baths, creating a luxurious and long - lasting foam. In liquid soaps, it provides thickening and cleansing functions, while also being gentle on the skin.
• Pearlescent Products: Coconut Oil Monoethanolamide is often used in the preparation of pearlescent detergents and products. It has emulsifying and light - shielding properties that help in creating the pearlescent effect, making products like pearlescent shampoos and body washes more aesthetically appealing.

5.2 Household Cleaning Products

• Solid and Liquid Detergents: In solid soap, soap powder, and liquid laundry detergents, it is used as a detergent, foam booster, and thickener. It helps in the removal of various types of stains, including oil - based and protein - based stains, and improves the overall cleaning performance of the detergent.
• Dishwashing Liquids: It can be added to dishwashing liquids to enhance foam stability and cleaning power. Its ability to emulsify grease and oils makes it effective in removing food residues from dishes.

5.3 Other Industrial Applications

• Textile and Leather Industry: In the textile industry, it can be used as a fiber softener, anti - static agent, and detergent. It helps to make fabrics softer, reduces static electricity during processing and use, and can be used in textile washing formulations. In the leather industry, it may be used in leather cleaning and conditioning products to clean and soften the leather.
• Cosmetic and Pharmaceutical Emulsions: Due to its excellent emulsifying properties, it can be used in the formulation of cosmetic emulsions such as creams and lotions, as well as in some pharmaceutical emulsions, to ensure the stability of the product and the proper dispersion of active ingredients.

6. Recommended Dosage

• The recommended dosage of Coconut Oil Monoethanolamide in most applications typically ranges from 1% - 3% by weight of the final product formulation. However, the exact dosage may vary depending on the specific application, the type and concentration of other ingredients in the formulation, and the desired product performance. For example, in some high - end personal care products where a more intense thickening or foaming effect is required, the dosage may be closer to 3%, while in some industrial cleaning products with a more complex formulation, a lower dosage of around 1% - 2% may be sufficient.

7. Packaging and Storage

• Packaging: It is usually packaged in 25 - kg paper - plastic composite bags, which provide good protection against moisture and physical damage during storage and transportation. For larger - scale industrial users, it may also be available in bulk containers.
• Storage: Store it in a cool, dry place away from direct sunlight and heat sources. The storage area should be well - ventilated. Avoid storing it near strong oxidizing agents or acids, as it may react with them. Under
