AUR-Glucan

Q: What is the recommended usage rate for AUR-Glucan?

The recommended usage range is 1%–5%. Use 1%–2% for hydration boosts and sensory enhancement, and 3%–5% for intensive moisturization and barrier support.

Q: How does AUR-Glucan (β-Glucan) work?

It binds water and forms a thin, breathable film on the skin’s surface to help reduce TEWL, smooth texture, and support the skin’s natural barrier and comfort.

Q: How does it compare to Hyaluronic Acid?

Both are effective humectants. β-Glucan also contributes a distinct film-forming effect that helps lock in moisture and provides a silky, cushiony feel, with additional soothing benefits.

Q: What is the optimal pH range for AUR-Glucan?

Formulate within pH 4.0–7.0 for stability and performance.

Q: Is AUR-Glucan suitable for sensitive skin?

Yes. Its hydrating and comforting properties make it well-suited for dry, dehydrated, or sensitive skin, including post-care routines.

Q: Is this ingredient derived from oats?

No. AUR-Glucan is produced by fermenting the yeast Aureobasidium pullulans, providing a grain-free source of β-Glucan.

Q: Will the film-forming property feel heavy or clog pores?

No. The film is thin, flexible, and breathable, offering a smooth, non-occlusive, non-tacky finish.

Performance & Formulation Insights for AUR-Glucan

How β-Glucan Works for Superior Hydration

AUR-Glucan delivers dual-action hydration powered by β-Glucan produced via fermentation of the yeast Aureobasidium pullulans. As a highly hydrophilic polysaccharide, β-Glucan binds and holds water at the skin’s surface while forming a thin, flexible, breathable film. This film helps reduce transepidermal water loss (TEWL), cushions the skin, and imparts a silky, non-tacky finish. Beyond moisturization, β-Glucan is widely appreciated for its skin-comforting properties and support of the skin’s natural barrier function, making it ideal for dry, dehydrated, or sensitive skin.

Formulation Guidelines

AUR-Glucan is a water-soluble liquid that can be added to the water phase or during the cool-down stage to maintain integrity of the biopolymer. Recommended usage is 1–5%, with 1–2% for hydration boosts and sensory enhancement, and 3–5% for intensive moisturization and barrier support. It is compatible across typical skincare pH ranges (4.0–7.0) and layers well with other humectants such as hyaluronic acid and glycerin, as well as barrier-supportive ingredients.
