Patent No.No. 4000078Registration DateAugust 17, 2007
Aureo culture fluid and EF lactic acid bacteria, which are highly effective moisturizers, were found to be highly safe skin moisturizers with excellent durability of moisturizing effect and usability.Aureo culture fluid is characterized by its β1,3-1,6 bonding, which has physiological activities such as anti-allergic and anti-inflammatory effects, so it is expected not only to moisturize but also to reduce allergic symptoms such as atopic dermatitis.Aureo culture fluid and EF lactic acid bacteria were applied to the skin of women in their 20s to 50s, and the moisture content in the stratum corneum of the epidermis was measured.In a mouse test conducted at Tokyo Denki University, the amount of hyaluronic acid as well as ceramide, which is necessary to maintain the moisturizing effect and protect the skin from external stimuli, increased.
This Japanese patent (Patent No. 4000078) covers Aureobasidium pullulans-derived β-glucan as a moisturizer for skin, protecting cosmeceutical applications of this multifunctional polysaccharide.
AP β-glucan demonstrated skin moisturizing properties in the patent claims. The hygroscopic properties of the β-glucan polysaccharide enable water retention in skin, while its anti-inflammatory activities may reduce skin irritation. These properties support AP-glucan's use in skincare applications.
Cosmeceutical patents for AP-glucan demonstrate its versatile applications beyond immune health into skincare and dermatology. The moisturizing and potential anti-inflammatory skin effects represent an additional commercial application for Aureobasidium pullulans-derived β-glucan.
