- Emulsification: AEO-9 excels at breaking down and dispersing oily stains and soils during the washing process, ensuring they don’t stand a chance.
- Foaming Agent: While excessive foam isn’t always desirable, controlled foaming with AEO-9 helps lift and suspend dirt and grime.
- Decontamination: AEO-9 is a key player in the decontamination process by enhancing the detergent’s ability to dislodge and remove various types of dirt and stains from fabrics.
- Biodegradability: AEO-9’s high biodegradability makes it an eco-friendly ingredient in detergent formulations.
- Solubility: AEO-9 exhibits good solubility, ensuring it can be effectively dispersed in the liquid detergent.
Amount of AEO-9 in Liquid Detergent:
AEO-9 is usually found in concentrations ranging from 1% to 2% by weight in liquid detergents. The specific amount may vary depending on the manufacturer’s goals for cleaning and foaming performance.
The Role and Amount of CDEA in Liquid Detergent
Role of CDEA in Liquid Detergent:
Cocamide Diethanolamine (CDEA) is a key player in liquid detergents, contributing its unique attributes to the formula:
- Foaming Agent: CDEA is renowned for its foaming properties. When added to liquid detergents, it enhances the foaming capacity of the product. This is particularly valuable in products like shampoos and liquid soaps, where rich lathering is desired.
- Viscosity Enhancer: CDEA increases the viscosity of liquid detergents, contributing to their texture and stability. This property enhances the user experience, making the product feel more substantial and easier to apply.
- Cleaning Power: CDEA also contributes to the cleaning power of liquid detergents, particularly for removing greasy and oily dirt. It aids in breaking down and emulsifying oils and dirt for effective cleaning.
- Dermatological Effect: In personal care products like shampoos and liquid soaps, CDEA can provide a soothing and moisturizing effect on the skin.
Amount of CDEA in Liquid Detergent:
Liquid detergents typically contain 2% to 4% CDEA by weight. This ingredient enhances foaming and cleaning performance, particularly in high-foaming products like shampoos and body washes.
The Role and Amount of EDTA in Liquid Detergent
Role of EDTA in Liquid Detergent:
Ethylenediaminetetraacetic Acid (EDTA) is a significant component in the formulation of liquid detergents, contributing its unique properties:
- Water Softening: EDTA acts as a chelating agent, binding to metal ions like calcium and magnesium in hard water. This softens the water, allowing the primary surfactants to work more effectively and preventing mineral deposits on fabrics.
- Stain Removal: By sequestering metal ions, EDTA prevents them from binding to stains or fabrics, making it easier for the detergent to break down and remove stains.
- Preservative: EDTA can also act as a preservative in liquid detergents, extending the product’s shelf life by inhibiting the growth of microorganisms and maintaining stability.
Amount of EDTA in Liquid Detergent:
The concentration of EDTA in liquid detergents can vary depending on the specific formulation and product requirements. In general, EDTA is used in relatively small percentages compared to primary surfactants. The amount of EDTA is carefully adjusted to achieve the desired water softening and stain removal effects without overloading the product with unnecessary chelating agents.
It is common for the concentration of EDTA in household laundry detergents to range from 0.5% to 5% by weight. However, the exact percentage may vary between different brands and formulations. Manufacturers carefully consider the balance of ingredients to optimize the detergent’s performance, especially in regions with hard water.
The Role and Amount of Sodium Chloride in Liquid Detergent:
Role of Sodium Chloride in Liquid Detergent:
Sodium chloride, or table salt (NaCl), plays a specific role in liquid detergent formulations:
- Viscosity and Thickness: It increases the detergent’s viscosity and thickness for user convenience.
- Enhanced Detergent Texture: Sodium chloride provides a balanced texture to the detergent. It contributes to the solid consistency of the liquid detergent, ensuring it’s neither too thick nor too thin. This balance is crucial for user convenience and product stability.
- Stabilizing Surfactants: Sodium chloride helps stabilize the surfactants in the detergent, ensuring that they maintain their performance over time. Surfactants are responsible for breaking down and removing stains, so their stability is essential for effective cleaning.
- Reduced Separation: Sodium chloride helps detergent ingredients adhere to one another, preventing phase separation and ensuring the uniform distribution of components in the liquid detergent.
Amount of Sodium Chloride in Liquid Detergent:
Typically, sodium chloride is added at concentrations of 2-3% by weight, carefully adjusted to achieve the desired thickening and stabilization effects without compromising the performance of other detergent components.
The Role and Amount of Deionized Water in Liquid Detergent:
Role of Deionized Water in Liquid Detergent:
Deionized water, often abbreviated as DI water or simply as distilled water, plays a crucial role in the formulation of liquid detergents:
- Solvent and Carrier: Deionized water acts as a solvent and carrier for the various detergent ingredients. It provides a medium in which other components can be dissolved or suspended, ensuring they are evenly distributed throughout the detergent.
- Dilution and Concentration: Manufacturers use deionized water to control the concentration of the detergent. By adding the appropriate amount of water, they can adjust the concentration of the detergent solution to meet the desired product specifications.
- Preventing Residue and Stains: Deionized water is particularly useful because it contains no minerals or ions. This lack of impurities means that it leaves behind no residue, spots, or stains on surfaces or clothing when used in detergents. It helps ensure that the cleaning process leaves surfaces or fabrics spotless.
