Overview of Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90%
Surfactants, short for surface-active agents, are compounds that lower the surface tension between two liquids or between a liquid and a solid. They play a crucial role in various industries due to their unique ability to interact with interfaces, enhancing emulsification, dispersion, wetting, foaming, and detergency properties.
Surfactants typically have an amphiphilic nature, meaning they consist of both hydrophilic (water-loving) and hydrophobic (water-repellent) parts. This dual nature enables them to orient themselves at the interface between water and other substances, reducing the interfacial tension. The hydrophilic part is usually polar and often contains oxygen, nitrogen, or sulfur atoms, while the hydrophobic part is typically a long hydrocarbon chain.
Functions of Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90%
- Emulsification: By reducing the interfacial tension, surfactants facilitate the formation and stabilization of emulsions, where one liquid is dispersed in another immiscible liquid.
- Detergency: They help remove dirt and oils from surfaces by lowering the surface tension of water, allowing it to penetrate better into fabrics or surfaces, and by solubilizing greasy substances.
- Wetting: Surfactants speed up the wetting process by reducing the contact angle between a liquid and a solid, enhancing spreading.
- Foaming and Anti-Foaming: Depending on the type, surfactants can either stabilize foam (as in shampoo and soap) or break it down (in industrial processes where foam is undesirable).
- Dispersing Agent: They keep particles suspended in a liquid medium, preventing aggregation and settling.
Applications of Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90%
- Household and Industrial Cleaning Products: Detergents, soaps, and cleaning agents all rely on surfactants to remove dirt and grease.
- Personal Care and Cosmetics: Shampoos, conditioners, toothpaste, and skincare products use surfactants for cleansing, foaming, and emulsifying.
- Textile and Leather Processing: In textile manufacturing, surfactants assist in dyeing, finishing, and fabric softening.
- Agriculture: As adjuvants in pesticides and herbicides, surfactants improve the spreading and sticking of these chemicals to plant surfaces.
- Food Industry: Used as emulsifiers in foods like mayonnaise, ice cream, and salad dressings to stabilize mixtures.
- Oil Recovery and Environmental Remediation: Surfactants can enhance oil recovery in petroleum extraction and aid in the cleanup of oil spills.

Parameters of Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90%
CAS No. 2809-21-4 refers to the chemical compound Hydroxyethyl Disodium Phosphate (HEDP), which is a widely used chelating detergent and a sequestrant agent. HEDP, also known as sodium hexametaphosphate, falls under the category of synthetic surfactants.
Here’s a breakdown of some key parameters for HEDP with concentrations of 60% and 90%:
1. **Chemical Formula**: Na2O(CH2)6PO4.H2O
2. **Molecular Weight**: Approximately 258.1 g/mol
3. **Function**: It acts as a chelating agent, meaning it can form stable complexes with metal ions, preventing them from reacting with other substances and improving water hardness control in detergents.
4. **60% Solution**: A 60% HEDP solution would have 60% weight of HEDP in the mixture, with the remaining 40% being water or other solvents, depending on the formulation.
5. **90% Solution**: A 90% HEDP solution would have a higher concentration of the active ingredient, providing stronger chelating properties. However, this might be less common in consumer products due to increased viscosity and potential handling challenges.
6. **pH**: HEDP solutions typically have a neutral to slightly basic pH, around 7 to 8, which helps maintain the stability of the complexes formed.
7. **Solubility**: HEDP is highly soluble in water, making it easy to incorporate into various cleaning formulations.
8. **Application**: Common applications include laundry detergents, dishwashing liquids, industrial cleaners, and water treatment processes to soften water and prevent scale formation.
9. **Safety and Regulations**: HEDP is generally considered safe for use, but it’s essential to follow proper handling, storage, and disposal guidelines to ensure safety.
Please note that specific parameters like melting point, boiling point, and other physical properties would depend on the exact formulation and conditions. Always consult the manufacturer’s data sheet for detailed information.

FAQs of Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90%
Q1. What exactly do Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% do?
A: Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% lower the surface tension between fluids or between a fluid and a solid, improving properties such as wetting, foaming, detergency, emulsification, and dispersing. They achieve this through their amphiphilic structure, which allows them to interact effectively at interfaces.
Q2. Are surfactants safe for the environment?
A: The environmental impact of Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% varies greatly depending on their type, concentration, and the specific environment they enter. Some surfactants are biodegradable and pose minimal risk when used and disposed of properly. However, non-biodegradable surfactants can accumulate and harm aquatic life. It’s essential to choose eco-friendly options and follow recommended disposal guidelines.
Q3. How do Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% affect skin and hair?
A: Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% in personal care products can have both positive and negative effects. They help clean by removing dirt and oil but may also strip natural oils from the skin and hair, leading to dryness or irritation. Mild or moisturizing surfactants are often used in formulations to minimize these side effects.
Q4. How do Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% contribute to the effectiveness of cleaning products?
A: In cleaning products, Cas No. 2809-21-4 Special Synthetic Surfactant Detergent HEDP 60% 90% work by surrounding dirt particles, making them more soluble in water. They also reduce the surface tension of water, enabling it to penetrate better into fabrics and surfaces, and lift away grease and grime. This dual action of solubilization and penetration significantly enhances cleaning efficiency.
Q5. Why do some surfactants produce more foam than others?
A: The foaming capacity of surfactants depends on their molecular structure and the solution conditions. Generally, surfactants with long hydrocarbon chains and high concentrations tend to produce more stable foam because they can trap air more effectively. Additionally, anionic and nonionic surfactants are often associated with good foaming properties compared to cationic ones.
Q7. How do you determine the right surfactant for a specific application?
A: Choosing the right surfactant involves considering factors such as the required function (e.g., cleaning, emulsifying, wetting), compatibility with other ingredients in the formulation, environmental and safety regulations, cost-effectiveness, and desired end-product properties. Testing different surfactants in small-scale experiments is often necessary to identify the optimal choice for a given application.
