2025-08-01

PEG-100 Stearate emulsifier is a versatile ingredient commonly used in the chemical industry, specifically within the realm of surface-active agents and emulsifiers. As a non-ionic surfactant, it plays an essential role in stabilizing emulsions, which are mixtures of two immiscible liquids, such as oil and water. This makes it particularly valuable in formulating cosmetic products, pharmaceuticals, and various household items.
The primary component of PEG-100 Stearate is polyethylene glycol (PEG) combined with stearic acid. The "100" in its name refers to the average molecular weight of the PEG portion, indicating a moderate level of ethylene oxide units. This characteristic contributes to its unique emulsifying properties, allowing it to effectively blend oils with water, thereby creating stable emulsions.
One of the key benefits of PEG-100 Stearate emulsifier is its ability to enhance texture and viscosity in formulations. It provides a smooth, creamy consistency that is often desirable in lotions and creams. Additionally, its emollient properties help to soften and soothe the skin, making it a popular choice in cosmetic formulations aimed at moisturizing benefits.
Moreover, PEG-100 Stearate emulsifier is known for its compatibility with a wide range of ingredients. This compatibility makes it easy to incorporate into various formulations without compromising the stability or performance of other components. It can function in both oil-in-water (O/W) and water-in-oil (W/O) emulsions, providing formulators with the flexibility to create diverse products tailored to specific consumer needs.
In terms of safety, PEG-100 Stearate emulsifier has been extensively evaluated and is generally recognized as safe for use in cosmetic and personal care products. However, it is important for formulators to adhere to recommended usage levels and to consider the overall formulation to ensure product safety and efficacy.
In conclusion, PEG-100 Stearate emulsifier serves as a critical ingredient in the formulation of various products across different industries. Its effective emulsifying properties, combined with its ability to improve texture and compatibility, make it an essential component for formulators looking to create stable and appealing products. Understanding its role and functionality can assist manufacturers in optimizing their formulations to meet consumer demands and preferences.
