Overview of Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6
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 Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6
- 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 Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6
- 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 Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6
Sodium Lauroyl Sarcosinate (LS-30) is a mild surfactant that is commonly used in personal care products such as shampoos, soaps, and body washes due to its excellent emulsifying and foaming properties. It is derived from sodium salt of lauroyl sarcosine, which is a fatty acid derived from the amino acid sarcosine.
Here’s a breakdown of some key parameters for Sodium Lauroyl Sarcosinate (CAS No. 137-16-6):
1. Appearance: Colorless or light yellow transparent liquid – This means it has a clear and translucent appearance, making it suitable for products where a visually appealing and clean look is desired.
2. Chemical Formula: NaC12H25SO3N + CH3CH2COONa – The compound consists of a sodium salt (Na+) combined with the lauroyl sarcosinate ester (C12H25SO3N) and a sarcosinolate (CH3CH2COONa).
3. Function: Surfactant – It acts as an emulsifier, helping to blend oil and water-based ingredients, and as a foaming agent, creating a stable lather.
4. pH Compatibility: Mild nature makes it suitable for use in a wide range of pH levels, typically compatible with skin and hair care products that need to maintain a gentle pH.
5. Biodegradability: Sodium Lauroyl Sarcosinate is biodegradable, which means it breaks down naturally in the environment, reducing its environmental impact.
6. Safety: It is generally considered safe for use in cosmetic and personal care products, but like any ingredient, it may cause allergic reactions in some individuals. It is essential to perform a patch test before using it in formulations intended for sensitive skin.
7. Solubility: It is soluble in water, making it easy to incorporate into various product formulations.
8. Regulatory Status: It meets the requirements of many international cosmetic regulations, including EU (Cosmetics Regulation 1223/2009), FDA (U.S. Food and Drug Administration), and others.
In summary, Sodium Lauroyl Sarcosinate (LS-30) is a versatile, mild surfactant that contributes to the effectiveness and compatibility of personal care products while maintaining a low environmental impact.

FAQs of Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6
Q1. What exactly do Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 do?
A: Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 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 Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 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 Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 affect skin and hair?
A: Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 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 Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 contribute to the effectiveness of cleaning products?
A: In cleaning products, Sodium Lauroyl Sarcosinate LS-30 Mild surfactant Colorless or light yellow transparent liquid CAS 137-16-6 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.
