Methyl Glucose Sesquistearate, a nonionic water-in-oil emulsifier with an HLB value of 6.6, is primarily utilized in the formulation of creams, lotions, and cosmetics, particularly those intended for use near the eyes, due to its low potential for irritation. This emulsifier excels in providing effective emulsification and stability at minimal concentrations, enhancing emulsion viscosity while minimizing the necessity for additional thickening agents. It is effective in reinforcing and stabilizing molded products, such as sticks, by reducing syneresis and improving structural integrity. Additionally, Methyl Glucose Sesquistearate is valued in leather care for texture enhancement and offers moisture retention benefits in cleansing applications by acting as a mild barrier. It is frequently employed in a variety of skin care products, including lotions, creams, skin conditioning mousses, and decorative cosmetics. In combination with PEG-20 Methyl Glucose Sesquistearate, it delivers sophisticated oil-in-water emulsions with enhanced shelf life, viscosity, and stability, providing notable safety and performance benefits compared to traditional emulsifiers.
What is Methyl Glucose Sesquistearate, and what are its main properties?
Methyl Glucose Sesquistearate is a mixture of mono- and diesters of methyl glucose and stearic acid. These are solid, off-white flakes that serve as a nonionic water-in-oil emulsifier with a Hydrophilic-Lipophilic Balance (HLB) value of 6.6. It is known for its low eye irritation profile and is commonly used in creams, lotions, and makeup products.
How is Methyl Glucose Sesquistearate beneficial in cosmetic formulations?
It provides effective emulsification and stability even at low concentrations, enhancing emulsion viscosity and reducing the need for additional thickeners. This emulsifier helps in strengthening and rigidifying molded sticks, reducing syneresis, and acts as a stabilizer in multiple-phase makeup products.
Is Methyl Glucose Sesquistearate safe for sensitive skin, particularly around the eyes?
Yes, Methyl Glucose Sesquistearate is considered safe for sensitive skin, especially around the eyes. Human patch tests have demonstrated no irritation or sensitization, making it an ideal ingredient for eye-area cosmetics.
In what types of products can Methyl Glucose Sesquistearate be used?
Methyl Glucose Sesquistearate is versatile and can be used in a variety of personal care products, including lotions, creams, skin conditioning mousses, decorative cosmetics, and as a moisture-retentive barrier in cleansing applications.
How does Methyl Glucose Sesquistearate enhance the performance of molded cosmetic sticks?
It strengthens and rigidifies molded sticks, thereby significantly reducing syneresis. This means the product is less likely to experience phase separation or liquid exudation, maintaining its integrity and longevity.
What are the benefits of combining Methyl Glucose Sesquistearate with PEG-20 Methyl Glucose Sesquistearate in formulations?
Combining these two compounds produces elegant oil-in-water emulsions with enhanced long-term shelf life, viscosity, and stability. This potent combination offers superior safety and performance advantages compared to traditional emulsifiers when used together in formulations.
