Overview of Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats
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 Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats
- 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 Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats
- 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 Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats
CAS Number: 91995-81-2 refers to the chemical compound Ethoxylated Quaternary Ammonium Compound (EQA or Ethoxylated Quaternary Ammonium Salt), which is commonly used as a cationic surfactant in detergents and other cleaning agents.
Parameters of this raw material:
1. Chemical Name: Ethoxylated Quaternary Ammonium Compound
2. Formula: Generally represented as (R4N+)(C12H25O)X, where R4N+ is a quaternary ammonium group (e.g., methyl, ethyl, butyl, or propyl), and X is the number of ethoxy (CH2(OH)) groups attached (e.g., X = n for nethoxylated).
3. Structure: A cationic surfactant with an ionic head group derived from a quaternary ammonium molecule and an alkyl chain, which provides water solubility and cleaning properties.
4. Function: In detergents, EQA acts as an emulsifier, wetting agent, and antimicrobial agent. Its cationic nature helps in removing soil and grease by neutralizing anionic substances, while its hydrophobic tail allows it to bind to dirt particles.
5. Properties:
– Water soluble: EQAs are typically soluble in water due to the presence of ethoxy groups.
– pH sensitivity: They can be sensitive to pH changes, often requiring a slightly acidic environment to maintain their effectiveness.
– Biodegradability: Some formulations may be biodegradable, while others may have environmental concerns due to persistence in the environment.
– Compatibility: They can form complexes with anionic surfactants, enhancing their cleaning performance.
6. Applications: Commonly used in fabric softeners, laundry detergents, dishwashing liquids, and personal care products like shampoos and conditioners.
Please note that specific details may vary depending on the exact chemical structure and formulation of the detergent containing this raw material.

FAQs of Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats
Q1. What exactly do Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats do?
A: Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats 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 Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats 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 Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats affect skin and hair?
A: Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats 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 Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats contribute to the effectiveness of cleaning products?
A: In cleaning products, Detergent Raw Materials CAS 91995-81-2 Cationic Surfactant Ester Quats 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.
