Overview of anionic surfactant sodium lauryl ether sulfate sles 70% powder K12
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 anionic surfactant sodium lauryl ether sulfate sles 70% powder K12
-
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 anionic surfactant sodium lauryl ether sulfate sles 70% powder K12
The sodium lauryl ether sulfate (SLES) anionic surfactant has a molecular weight of approximately 894 g/mol and a melting point of around 100°C. It is commonly used as a preservative in various industries, including cosmetics, detergents, and pharmaceuticals.
The “K” parameter refers to the skin stability index, which measures how well SLES retains its surface tension on the skin over time. A higher K value indicates better skin stability, while a lower K value suggests increased skin sensitivity or irritation.
To determine the K parameter of SLES, you would need to perform a stability study using the relevant testing methods. This may involve measuring the degree of moisture retention of SLES on a surface at different temperatures and under different humidity levels, as well as evaluating its overall skin compatibility with other ingredients.

FAQs of anionic surfactant sodium lauryl ether sulfate sles 70% powder K12
Q: Is anionic surfactant sodium lauryl ether sulfate sles 70% powder K12 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 anionic surfactant sodium lauryl ether sulfate sles 70% powder K12 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 anionic surfactant sodium lauryl ether sulfate sles 70% powder K12 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 anionic surfactant sodium lauryl ether sulfate sles 70% powder K12 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 anionic surfactant sodium lauryl ether sulfate sles 70% powder K12?
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.
