Procedures

Phase A: Preparing the Base

  1. Add Deionized Water: Start with a clean mixing beaker. Measure and pour 153.60 g of deionized water into the beaker.
  2. Dissolve EDTA-2Na: Gradually add 0.40 g of EDTA-2Na to the water. Stir the mixture until the EDTA-2Na is completely dissolved. This ingredient acts as a chelating agent, binding metal ions and enhancing the cleaning efficiency.
  3. Adjust pH with Caustic Soda: Carefully add 1.30 g of caustic soda (sodium hydroxide) to the mixture. Stir gently until the solution is homogeneous. Caustic soda helps to neutralize LABSA and stabilize the pH.

Phase B: Adding Surfactants

  1. Add LABSA 96%: Slowly introduce 10.00 g of LABSA 96% to the mixture. Stir gently to prevent excessive foaming. LABSA is a potent anionic surfactant, excellent for removing grease and dirt.
  2. Add SLES 70%: Add 16.00 g of SLES 70% while continuing to stir gently. SLES is another anionic surfactant that enhances cleaning power and foaming.
  3. Add CAB 35%: Add 8.00 g of CAB 35%, stirring until fully blended. This amphoteric surfactant helps to boost foam and reduce skin irritation.
  4. Add AEO-9 99%: Add 3.00 g of AEO-9, a non-ionic surfactant that enhances cleaning power and is gentle on fabrics.
  5. Add CDEA 85%: Incorporate 3.00 g of CDEA 85% into the blend. Stir thoroughly until the mixture is homogeneous. CDEA increases foam stability and improves viscosity.

Phase C: Final Additives

  1. Add Fragrance and Preservatives: Add your preferred fragrance for a pleasant scent. Follow with an appropriate amount of preservative, such as Methylisothiazolinone (MIT), to ensure the product remains fresh.
  2. Thickening with Sodium Chloride: Slowly add sodium chloride (salt) to achieve the desired thickness. Be cautious to avoid over-thickening, which can cause the detergent to become too viscous.
  3. Colorant (Optional): Add a few drops of colorant if desired. Stir until the color is evenly distributed.

Final Steps

  1. Mix Thoroughly: Ensure all ingredients are fully dissolved and the mixture is uniform. This step is crucial for the performance and stability of the detergent.
  2. Quality Control: Take a sample of the detergent for testing. Check the pH and viscosity to ensure they meet your desired specifications.
  3. Packaging: Once the detergent passes quality control, it’s ready to be packaged. Use clean, dry containers, and label them with the contents and date of production.

Safety and Storage

  • Safety Precautions: Always handle chemicals with care. Use gloves and eye protection to avoid irritation.
  • Storage: Store the finished detergent in a cool, dry place, away from direct sunlight.

What is AEO-9? Key Features

AEO 9 sample pic

AEO-9, a Fatty Alcohol Polyoxyethylene Ether, is a nonionic surfactant widely used in various detergent formulations. It is composed of a fatty alcohol base that is ethoxylated with nine ethylene oxide units. The chemical structure can be represented as R-(OCH₂CH₂) n-OH, where ‘R’ represents a fatty alkyl group derived from natural sources like coconut or palm oil, and ‘n’ indicates the number of ethylene oxide units, which in this case is nine.

The chemical structure can be represented as R-(OCH₂CH₂) n-OH, where ‘R’ represents a fatty alkyl group derived from natural sources like coconut or palm oil, and ‘n’ indicates the number of ethylene oxide units, which in this case is nine.

· Nonionic Nature: AEO-9 is a nonionic surfactant, meaning it does not carry any charge on its hydrophilic (water-attracting) head group. This property makes it compatible with a wide range of other surfactants and ingredients, including anionic, cationic, and other nonionic substances.

· Excellent Emulsifying and Dispersing Properties: The structure of AEO-9 allows it to effectively lower the surface tension of water, helping to emulsify oils and disperse solid particles. This makes it highly effective in cleaning applications where breaking down greasy and oily residues is essential.

· Biodegradability: AEO-9 is readily biodegradable, meaning it can be broken down by microorganisms in the environment and the breakdown results are all nontoxic and eco-friendly. This property is particularly important in reducing the ecological impact of detergents and cleaning products that may enter water systems. Before AEO-9, np-9 and np-10, both being Polyoxyethylene Nonylphenol, were commonly used as the emulsifying and degreasing agents in detergents. However, both np-9 and np-10 are characterized by high resistance to degradation processes, while showing a tendency to bioaccumulation. And they are considered as Endocrine disrupting compounds (EDCs) that pose significant environmental risks, particularly to aquatic ecosystems.

AEO-9 is so far the best replacement option for NP-9 and NP-10 in detergents.

· Solubility: AEO-9 is readily soluble in water and various organic solvents, which enhances its versatility in formulation. It can be used in both aqueous(common liquid detergents) and non-aqueous(detergent pods) systems, making it suitable for a wide range of cleaning products.

· Mildness: Due to its nonionic nature and structure, AEO-9 is generally mild on the skin, reducing the risk of irritation compared to harsher surfactants like sulfates. This makes it suitable for formulations that come into direct contact with the skin, such as hand dishwashing liquids and personal care products. However, it is worth noting that AEO-9 has a very strong degreasing ability, and when it is excessively used in hand-washing formulas, it may stripe out the protective sebums in our skin, leading to dryness and even peeling.

The Usage Parameters

Concentration:

  • The typical usage concentration of AEO-9 in formulations can vary depending on the desired effect and the specific application. In liquid detergents, the concentration often ranges from 1% to 10%, with higher concentrations used in more demanding applications like industrial cleaners.
    • In hand-washing formulas, the dosage of AEO-9 is recommended to be below 1.5%, or otherwise, a compensatory skin-caring ingredient is necessary, such as Glycerine.
    • AEO-9 can thin the detergent formulas, so when high viscosity is desired for a formula, the dosage of AEO-9 must also be carefully considered, or otherwise, an additional thickening agent such as HPMC must be incorporated.

 pH Stability:

  • AEO-9 is stable across a wide pH range, typically from 3 to 12. This makes it versatile for use in both acidic and alkaline cleaning products without significant loss of performance.

 Temperature:

  • AEO-9 remains stable and effective across a broad temperature range. However, its physical state can change with temperature; it typically appears as a creamy paste below 23°C and as a clear, colorless to light yellow liquid above 23°C. This transition should be considered during storage and formulation.

Compatibility:

  • AEO-9 is compatible with many other nonionic surfactants, anionic surfactants (like SLES or LABSA), and amphoteric surfactants (like CAPB and CAO). It can be used in conjunction with these to enhance the cleaning power, foam stability, or mildness of the formulation.

 Solubility and Mixing:

  • When formulating with AEO-9, ensure it is properly mixed and dissolved, especially in water-based systems. It should be added to the formulation at a stage where thorough mixing can be achieved to prevent any phase separation.
