Dioctyl sulfosuccinate sodium salt is also called Docusate sodium(CAS 577-11-7),is a powerful anionic surfactant. Unlike nonionic surfactants, anionic surfactants will ionize into negatively charged molecules in aqueous solution, and have strong lubrication and detergency, making it excellent in cleaning and dispersion. Due to its unique molecular structure, docusate sodium can effectively reduce the interfacial tension between water and oil, making it a key ingredient in products such as tablets, cosmetic emulsions, and industrial lubricants. This article will explore the multiple uses of docusate sodium from the perspective of medical and industrial applications.

1. The “Smoothness” of Docusate Sodium in Medicine

In the pharmaceutical field, docusate sodium is known as the "king of lubrication" and is often used in drugs to treat constipation. Its working principle is to reduce the surface tension in the intestine, promote the penetration of water into the stool, and relieve intestinal discomfort. Many laxatives add a small amount of docusate sodium to enhance the effect.

In terms of lubricant selection, polyethylene glycol (PEG) is another commonly used ingredient. Compared with docusate sodium, PEG has different dissolution rates and water absorption. The combination of the two can achieve a more balanced effect in the treatment of constipation. Combining PEG and docusate sodium, the drug can both enhance lubrication and control the rate of liquid absorption, thereby providing a dual effect.

2. Application of docusate sodium in cosmetics: from smoothness to moisturizing

In addition to medical uses, docusate sodium is widely used in cosmetics, especially in lotions, creams and cleaning products, due to its stable and mild properties. The special structure of docusate sodium can form a stable emulsification system, helping immiscible ingredients such as water and oil to form a stable mixture.

Glyceryl glucoside is a powerful moisturizing ingredient, especially when used in conjunction with docusate sodium in anti-aging products, it can significantly improve hydration. The combination of the two not only enhances the stability of the product, but also makes the ingredients gentler on the skin. For creams and essences, the combination of docusate sodium and glyceryl glucoside can make the moisturizing effect lasting, thereby effectively combating dry skin.

3. Industrial cleaning and solvents: the “hardcore” application of docusate sodium in cleaning

In industrial cleaning agents, docusate sodium is a non-toxic active agent widely used in metal cleaning, machine lubrication and other scenarios. Because it can effectively decompose grease, many degreasing cleaners contain docusate sodium, which is suitable for removing high-viscosity lubricants or fatty acids and other difficult-to-clean substances.

In industrial cleaning, sodium carboxymethyl cellulose (CMC) is used as a thickener and suspending agent in combination with docusate sodium. CMC can increase the viscosity of the solution, making docusate sodium more evenly distributed on the clean surface, thereby improving cleaning efficiency. This combination is particularly suitable for high-intensity cleaning of large equipment.

4. Environmentally friendly and sustainable future: the potential of green surfactants

With the advancement of the concept of sustainable development, the application potential of docusate sodium in environmentally friendly cleaning products is being widely studied. As a more environmentally friendly surfactant, it has a strong degradation ability under natural conditions, which is in line with the trend of sustainable development.

In green beauty,vitamin A propionate is a natural derivative that is favored for its mildness and biocompatibility. Combining docusate sodium with vitamin A propionate can reduce skin irritation in cosmetics while achieving environmental protection goals. For skin care brands that want to balance environmental protection and high efficiency, this combination is undoubtedly an ideal choice.
