Overview of Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant
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 Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant
- 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 Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant
- 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 Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant
Guerbet C12 alcohol ethoxylates, also known as alkyl ethoxylates or C12EOx (where x is the number of ethoxy groups), are nonionic surfactants with the CAS number 60636-37-5. These compounds are derived from the reaction between C12 fatty alcohols and ethylene oxide.
Parameters of Guerbet C12 alcohol ethoxylates as surfactants:
1. Structure: They consist of a hydrophobic fatty alcohol chain (C12) linked to multiple hydrophilic ethoxy (OCH2CH2-) groups through an ester bond. The number of ethoxy groups (x) determines the degree of hydrophilicity and the overall molecule’s balance between water solubility and oil compatibility.
2. Hydrophilic-lipophilic balance (HLB): The HLB value for C12 alcohol ethoxylates typically ranges from 9 to 14, depending on the specific ethoxylation level. Higher HLB values indicate greater hydrophilicity, making them suitable for use in aqueous systems.
3. Solubility: They are soluble in both water and oils, making them versatile surfactants that can act as emulsifiers, wetting agents, and foaming agents.
4. Surfactant properties: They exhibit good emulsifying, solubilizing, and dispersing abilities, which help to stabilize oil-in-water (O/W) or water-in-oil (W/O) emulsions.
5. Foaming properties: Depending on the ethoxylation level, Guerbet C12 alcohol ethoxylates can create mild to moderate foam, making them useful in personal care products like shampoos and soaps.
6. Biodegradability: They are generally biodegradable, contributing to their environmentally friendly nature, although the actual biodegradation rate may vary based on the specific ester bond structure and environmental conditions.
7. Skin and hair compatibility: Due to their mild nature, they are often used in cosmetic and personal care formulations, providing a gentle cleansing and conditioning effect.
8. Application: Common applications include detergents, adhesives, coatings, paper and pulp processing, and pharmaceuticals.
Remember that the exact properties of a Guerbet C12 alcohol ethoxylate may vary depending on the specific formulation and the degree of ethoxylation (x). It is essential to consult the manufacturer’s specifications for detailed information on the product’s performance and recommended usage.

FAQs of Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant
Q1. What exactly do Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant do?
A: Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant 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 Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant 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 Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant affect skin and hair?
A: Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant 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 Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant contribute to the effectiveness of cleaning products?
A: In cleaning products, Guerbet C12 alcohol ethoxylates CAS 60636-37-5 surfactant 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.
