Overview of Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate
Anionic surfactants are a class of surface-active agents characterized by a negatively charged hydrophilic head group when dissolved in water. This charge arises from the presence of a sulfate, sulfonate, phosphate, or carboxylate group. They are among the most widely used surfactants due to their effective cleaning properties, foaming capacity, and broad compatibility with other formulation ingredients. Anionic surfactants find extensive application across industries, including personal care, household cleaning, textiles, and industrial processes.
Features of Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate
-
Negative Charge: The anionic head group imparts water solubility and enables interaction with positively charged surfaces or particles.
-
Detergency: Exceptional at removing dirt, grease, and oils due to their strong polarity and ability to penetrate and disrupt these substances.
-
Foaming Properties: Many anionic surfactants generate stable and abundant foam, making them ideal for applications where lather is desired.
-
Cost-Effectiveness: They are often less expensive than nonionic, cationic, or amphoteric surfactants due to the abundance of raw materials and established production processes.
-
Compatibility: Can be combined with other surfactants to enhance performance or adjust properties, although care must be taken to avoid precipitation or incompatibility issues.
-
Environmental Considerations: Some anionic surfactants may pose environmental concerns due to their persistence or toxicity; however, biodegradable options are available.

Parameters of Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate
The parameter “Sles 70” in the context of anionic surfactants is likely referring to a specific type of anion surfactant that contains sodium lauryl ether (SL-81) and sulfuric acid as a primary component. The exact chemical formula for this surfactant can vary depending on the manufacturer or country, but it typically includes ingredients such as Sodium Lauryl Ether (SL-81), Potassium Acetate, Sodium Lauroyl Sulfonate (SL-82), Polyethylene glycol (PEG), Dimethyl Carbonate, Water, and/or Ammonia.
The “Anionic Surfactant Sodium Lauryl Ether Sulphate Parameter” refers to one of several parameters used to measure the performance of anionic surfactants in various applications. Some common parameters include:
1. cetrimonium chloride (CET)
* Cetrimonium chloride (CET) is a well-known anionic surfactant with a cationic group attached to its hydroxyl group. It is used primarily in hair care products due to its ability to cut and detangle hair.
2. trihexyldodecane hydrochloride (THD)
* HDL is another anionic surfactant commonly used in hair care products due to its effectiveness in removing dirt, oil, and other impurities from the hair.
3. amine derivatives (AMD)
* MDAs are anionic surfactants that contain a positively charged amino group attached to their hydroxyl groups. They are often used in personal care products such as soap, shampoo, and conditioners because they provide good foaming and lather properties.
4. alkylated sulfonates (ASs)
* ASs are anionic surfactants derived from alkyl sulfate groups. They are particularly useful in laundry detergents due to their high cleaning power and water resistance.
To determine the specific parameter value of “Sles 70” in the context of anionic surfactants, you would need to consult the product label or contact the manufacturer for more information about the specific formulation and characteristics of the surfactant.

FAQs of Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate
Q: Is Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate suitable for all skin types?
A: While commonly used, some anionic surfactants can be harsh on sensitive skin due to their strong cleansing action. Milder forms or combinations with other surfactant types are recommended for sensitive formulations.
Q: Does Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate biodegrade easily?
A: Biodegradability varies with the specific type of anionic surfactant. Linear alkylbenzene sulfonates (LAS) and alcohol ethoxysulfates (AES) are examples of biodegradable anionic surfactants commonly used in environmentally friendly products.
Q: Why does Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate foam so much?
A: Their molecular structure allows them to reduce the surface tension of water significantly, facilitating the formation of stable air bubbles and thus producing foam.
Q: Is Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate compatible with hard water?
A: Hard water can reduce the effectiveness of anionic surfactants by forming insoluble salts. However, builders like sodium tripolyphosphate are often added to counteract this effect.
Q: Are there any environmental concerns associated with Sles 70 Anionic Surfactants Sodium Lauryl Ether Sulphate?
A: Yes, certain anionic surfactants can persist in the environment or be toxic to aquatic life. Regulations exist to limit the use of harmful types, and research focuses on developing more eco-friendly alternatives.
