Overview of cosmetic raw material anionic surfactant AOS 35
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 cosmetic raw material anionic surfactant AOS 35
-
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 cosmetic raw material anionic surfactant AOS 35
Cosmetic raw materials such as anionic surfactants (AS) like AOS 35 can be classified into several parameters based on their properties and usage. Here are some of the most commonly used parameters:
1. Solubility: The solubility of anionic surfactants in water or other liquids is a measure of how easily they dissolve in the solution. A higher solubility indicates that the surfactant is more soluble and can dissolve more easily in the fluid.
2. Emulsification: Anionic surfactants are effective emulsifiers because they can help to stabilize mixtures of two immiscible liquids, such as oil and water. The effectiveness of anionic surfactants depends on the size and charge of the surfactant molecules and the compatibility of the surfactant with the oil droplets in the mixture.
3. pH stability: The pH stability of anionic surfactants is important because it affects their performance in various applications. Some surfactants become unstable at high pH values and lose their effectiveness in the presence of acids or bases.
4. Stability under heat: The stability of anionic surfactants under heat also depends on its chemical structure and composition. Some surfactants become more stable when heated due to changes in their molecular conformation, while others may lose their effectiveness at high temperatures.
5. Emulsion stability: The stability of anionic surfactants in emulsions depends on the size and charge of the surfactant molecules, as well as the compatibility of the surfactant with the droplets in the emulsion. Some surfactants are more effective in creating stable emulsions due to their ability to form strong interfacial bonds with the droplets.
Overall, the selection of anionic surfactant for a particular cosmetic application requires careful consideration of these factors and testing to determine the best choice for the specific application and environment.

FAQs of cosmetic raw material anionic surfactant AOS 35
Q: Is cosmetic raw material anionic surfactant AOS 35 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 cosmetic raw material anionic surfactant AOS 35 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 cosmetic raw material anionic surfactant AOS 35 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 cosmetic raw material anionic surfactant AOS 35 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 cosmetic raw material anionic surfactant AOS 35?
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.
