Product description

Ascorbyl Glucoside is a stable derivative of vitamin C, created by combining ascorbic acid with glucose (2-O-alpha-D-glucopyranosyl-L-ascorbic acid). In practice, it is a raw material produced by a biotechnological/enzymatic process (glycosylation), through which a bio-based form of vitamin C is obtained, with better stability in formulations and a lower tendency to undesirable darkening compared to pure ascorbic acid. On the skin, it behaves as a “vitamin C pool” – the enzyme α-glucosidase present on skin cell membranes gradually cleaves the bond and releases active vitamin C over time, which supports a longer-lasting effect without the sharp “shock” typical of less stable forms.

Key benefits

• Evening out skin tone and supporting brightening – helps reduce melanin production through tyrosinase inhibition.
• Supporting lightening of existing pigmentation – the released vitamin C can take part in reduction mechanisms in melanin.
• Antioxidant protection – helps reduce oxidative stress and supports skin defense after UV exposure.
• Anti-age effect – supports collagen production and improvement in the appearance of fine lines with regular use.
• Formulation stability – compared to pure vitamin C, it is more suitable for conventional emulsions and aqueous systems where a more stable performance is required.
• High tolerability – in formulations it is perceived as a mild and gentle vitamin C derivative.

Suitable for products such as

• Serums and facial emulsions for brightening and evening out skin tone
• Creams for dark spots and uneven skin tone
• Anti-age products (day/night creams, concentrates)
• After-sun and regenerative products after sun exposure
• Products with SPF (supporting antioxidant component)
• Cleansing products (gentle cleansing gels/cleansing waters) with appropriate pH adjustment

Use in formulation

• Soluble in: water (aqueous phase).
  In practice, it is recommended to dissolve it in a portion of the water/hydrolate during mixing and then add the remainder of the phase.
• Recommended dosage: commonly 0.5–2.0 % for daily use; for specific products, higher levels are possible (depending on the target and the formulation’s tolerability).
• Recommended pH of the finished formulation: typically 5.5–7.0 (suitable for most facial care products).
• Compatible with: O/W emulsions, gels, aqueous serums and hydration systems.
• Stabilization tips: at higher usage levels or higher manufacturing temperatures, the use of buffers (e.g. citrate system) and antioxidant auxiliaries helps to limit color changes.

Safety and storage

• Avoid contact with eyes and mucous membranes; in case of accidental contact, rinse with water.
• For sensitive skin, we recommend testing the tolerability of the finished product on a small area.
• Store in a well-closed container, in a dry place, at room temperature, protected from light and moisture.
