IO Vitamin C Derivative Cream Liquid

Most vitamin C derivatives are presented in thin serums and toners. IO Vitamin C Derivative Cream Liquid takes a different direction on its product card: creams, lotions and balms. That makes it interesting for brands that want a radiance ingredient in a comforting, emulsion-based product rather than in another watery serum.

The glyceryl ascorbate family

Glyceryl ascorbates are made by attaching ascorbic acid to glycerin. The result is more stable in water than pure vitamin C and brings a humectant character from the glycerin part. This ingredient range includes several grades; our catalog lists IO Vitamin C Derivative Liquid and IO Vitamin C Derivative Tonic Liquid as well. The exact INCI of MGA is confirmed on the supplier CoA for each lot, and that is the document to use for the ingredient list.

Specifications from the card

Liquid, soluble in water, pH 3.0 to 6.0 as supplied. Applications: creams, lotions and balms.

Why put a vitamin C derivative in a cream

Many customers prefer a single comforting cream over several layers of serums. Adding a stable vitamin C derivative to that cream lets the product carry a radiance message while still delivering moisture and barrier comfort. It also suits customers with dry skin who find thin acidic serums uncomfortable.

Product formats

Day cream

A light, fast-absorbing emulsion for morning use under sunscreen. The derivative supports a fresh-looking complexion.

Body lotion

Body lotions with vitamin C derivatives are less common and can stand out. Position them for a more even-looking, radiant skin on arms and legs.

Balm

Rich balms for dry areas such as hands, elbows and the face in winter. Check that the derivative stays evenly distributed in a high-wax base.

Formulating guidance

Add the liquid to the cooled emulsion below about 40 °C. Measure the pH immediately after addition and adjust to a mildly acidic range compatible with your preservative and emulsifier. Some emulsifiers lose stability at low pH, so choose a system that tolerates it, for example glucoside or polyglyceryl types. Protect the batch from strong light and metal ions. A gentle partner for an even-looking tone is beta arbutin; confirm compatibility in your base. More radiance ingredients are listed under actives.

Claims and communication

Use wording such as brighter-looking, more radiant and soft, comfortable skin. Mention that daily sun protection is part of any radiance routine. Base claims on testing of the finished product.

Packaging

Tubes and airless jars reduce air contact compared with open jars. For balms, a stick or a tin with a small surface area limits exposure. Opaque materials protect the ascorbate from light.

Testing program

Stability at room temperature, 40 °C and with light exposure for at least eight weeks. Check pH, viscosity, color and odor, and look for separation in emulsions at low pH. A centrifuge test helps predict long-term emulsion stability.

Range planning

A brand can build a simple radiance routine with this ingredient toner, this ingredient day cream and a separate sunscreen. Using related grades in different products keeps the vitamin C theme consistent across textures.
