Product description

Ascorbyl Glucoside is a stable vitamin C derivative that is formed 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), which yields a bio-based form of vitamin C with better stability in formulations and a lower tendency towards undesirable darkening compared to pure ascorbic acid. On the skin, it behaves like a “vitamin C pool” – the enzyme α-glucosidase present on the membranes of skin cells gradually cleaves the bond and releases active vitamin C over time, which supports a more long-lasting effect without the strong “shock” typical of less stable forms.

Key benefits

• Evening of skin tone and support of brightening – helps reduce melanin formation through tyrosinase inhibition.
• Support in lightening existing pigmentation – the released vitamin C can participate in reduction mechanisms in melanin.
• Antioxidant protection – helps reduce oxidative stress and supports the skin’s defenses 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 standard emulsions and aqueous systems where more stable performance is required.
• High tolerability – in formulations it is generally perceived as a mild and gentle vitamin C derivative.

Suitable for products such as

• Serums and facial emulsions for brightening and evening skin tone.
• Creams for pigment spots and uneven skin tone.
• Anti-age products (day/night creams, concentrates).
• After-sun and regenerating products after sun exposure.
• Products with SPF (supporting antioxidant component).
• Cleansing products (mild 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 part of the water/hydrolate while mixing, and only then add the remainder of the phase.
• Recommended dosage: typically 0.5–2.0% for daily use; for specific products it is possible to go higher (depending on the target and the tolerability of the formulation).
• 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 hydrating systems.
• Stabilisation tips: at higher dosages or higher manufacturing temperatures, the use of buffers (e.g. citrate system) and antioxidant auxiliaries helps to limit colour 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.
