Oleth-5 is a versatile surfactant with many uses. First, it dissolves well in alcohols, propylene glycol, cottonseed oil, and mineral oil. Moreover, it offers strong emulsifying, wetting, and dispersing abilities. For comparison, related products like OV-10 and OV-24 dissolve easily in water.

In cosmetics, Oleth-5 has several key roles. Primarily, it acts as a softener, lubricant, solubilizer, and emulsifier. For instance, manufacturers use it in astringent creams and lotions. Additionally, it solubilizes bromic acid for products like lipsticks and liquid hair balms. Furthermore, it is a common ingredient in foam baths, shampoos, cold wave agents, depilatory products, and hair straighteners.
Beyond personal care, Oleth-5 serves in specialized formulations. Specifically, it works as an oil-soluble spreading agent. This allows it to help create transparent gels from blends of mineral oil, isopropyl ester, oleyl alcohol, and water. In the pharmaceutical industry, companies mainly use it as an emulsifier, lubricant, and solubilizer for medicated creams and emulsions.
Finally, Oleth-5 has important industrial applications. It functions as an emulsifying wetting agent and a heavy-duty cleaner. Also, the rubber industry uses it as a dispersant. Most significantly, it is a key component in oil spill dispersants for the petroleum and environmental protection sectors.
In summary, Oleth-5 is a multifunctional ingredient that bridges cosmetic products, medicine, and heavy industry.
