Overview of Anionic Surfactant LAS 25155-30-0 SDBS for Detergent Powder
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 LAS 25155-30-0 SDBS for Detergent Powder
-
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 LAS 25155-30-0 SDBS for Detergent Powder
Anionic surfactants (ASs) are used in detergents due to their ability to adsorb dirt and oil onto surfaces. The parameter “LAS” stands for Los Angeles Anionic Surfactant, which is one type of AS. The number after “25155-30-0” refers to the molecular weight of the surfactant.
The formula for LAS 25155-30-0 is as follows:
LA25155-30-0 = 0.024 g/m^3 x (1 + 0.7059 x (molar mass of the soap base)) x (1 + 0.693 x (molar mass of the alkyl groups))
where:
* LA25155-30-0 is the molecular weight of the surfactant in grams per cubic meter
* molar mass of soap base is the molar mass of the sodium hydroxide, which is the main soap base in most detergents.
* molar mass of alkyl groups is the molar mass of each alkyl group in the soap base, such as benzene, ethyl alcohol, or methyl tertiary amine.
Using this formula, we can calculate the molecular weight of LAS 25155-30-0 based on its concentration and other factors. This information is important for determining the effectiveness of the AS in cleaning and removing dirt from surfaces.

FAQs of Anionic Surfactant LAS 25155-30-0 SDBS for Detergent Powder
Q: Is Anionic Surfactant LAS 25155-30-0 SDBS for Detergent Powder 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 LAS 25155-30-0 SDBS for Detergent Powder 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 LAS 25155-30-0 SDBS for Detergent Powder 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 LAS 25155-30-0 SDBS for Detergent Powder 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 LAS 25155-30-0 SDBS for Detergent Powder?
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.
