What is Alpha-Glucan?

Alpha-glucan (α-glucan) is a versatile polysaccharide with a range of roles in skincare formulations. Its molecular structure endows it with several beneficial properties, including acting as a chelating agent, bulking agent, prebiotic, and humectant.

 

 

Key Properties and Benefits

Chelating Agent: Alpha-glucan prevents metal ions and metallic compounds from interfering with the skin's function. This helps maintain the stability and efficacy of the formulation by minimizing potential interactions with other ingredients.

Bulking Agent: It increases the viscosity or thickness of cosmetic formulations. This can improve the texture and application experience of the product, contributing to a more desirable consistency.

Prebiotic: Alpha-glucan supports a healthy skin microbiome by nourishing beneficial microorganisms on the skin. This promotes a balanced skin environment, which is crucial for maintaining skin health and resilience.

Humectant: It attracts and retains moisture in the skin, ensuring sustained hydration. This property is essential for keeping the skin plump and supple.

Enhances Ingredient Delivery: Alpha-glucan's ability to improve the penetration of other ingredients in a formulation means that it can enhance the overall effectiveness of skincare products. This is particularly valuable in formulations designed to deliver active ingredients deeper into the skin.

Antioxidant Potential: Preliminary studies suggest that alpha-glucan may have antioxidant properties, which could help neutralize free radicals and protect the skin from oxidative stress.

 

 

Source and Usage

Alpha-glucan is commonly derived from natural sources like fungi, including mushrooms. While it offers notable benefits when applied topically, it does not have the same prebiotic effects when ingested due to its large size, which prevents it from being fermented by gut bacteria. Instead, it acts as an insoluble fiber as it passes through the digestive system.

 

 

Research and Comparison

The skin-specific benefits of alpha-glucan are less extensively researched compared to other glucans, such as beta-glucan and alpha-glucan oligosaccharide. Each of these glucans offers distinct properties and benefits, with alpha-glucan oligosaccharide being a popular derivative used in skincare for its specific functions.

 

 

FDA Status

While the FDA does not specifically approve alpha-glucan as a standalone ingredient, it is generally recognized as safe for use in cosmetics. The ingredient's safety is supported by its role in maintaining product stability and enhancing the efficacy of other active ingredients.

 

 

Conclusion

Alpha-glucan is a multifaceted ingredient with significant roles in skincare, including its functions as a chelating agent, bulking agent, prebiotic, and humectant. Its ability to enhance ingredient delivery and provide hydration makes it a valuable addition to various skincare formulations.
