K3 Vita-C



Highly stable water-soluble Vitamin C derivative

 

Effective in collagen synthesis at very low usage levels

 

No discoloration of formulations

Technology overview


K3 Vita-C is a water-soluble vitamin C derivative that is highly stable in finished products. It outperforms other vitamin C derivatives in, residual activity over time, color stability in finished products and in collagen formation performance.

 

K3 Vita-C’s stability was tested in function of time in a 1% aqueous solution at 25˚C in comparison to straight Ascorbic Acid, Ascorbic Acid-2-Glucoside (AA2G) and Magnesium Ascorbyl Phosphate (MAP). The residual activity of each product over time show clear difference, demonstrating the superior stability performance of K3 Vita-C.

 

The long-term stability of K3 Vita-C in finished formulations further ensures no discoloration of the products upon storage. Storage stability tests of 1% solutions of straight Ascorbic acid and several Vitamin C derivatives were performed at 50˚C for 30 days. Ascorbic Acid, AA2G and MAP show clear discoloration, whereas the samples containing K3 Vita-C shows no discoloration.

 

K3 Vita-C is very effective in collagen formation. In-vitro tests show that K3 Vita-C outperforms straight Ascorbic Acid and other Vitamin C derivatives (AA2G, MAP, SAP, ATM and Vitamin C Palmitate). The in-vitro tests involve culturing of cells in the presence of the various ingredients tested and concentrations of procollagen Type I C-peptide (PIP) is measured.

Application and uses


K3 Vita-C has a wide range of applications due to its stability and performance:

 

Skin care & anti-aging: Promotion of collagen synthesis, wrinkle reduction, prevention of discoloration from vitamin C and derivatives, adding other Vitamin C benefits including skin brightening and anti-oxidant properties

Formulation guidelines


The following formulation guidelines will help in successfully using K3 Vita-C  in formulations:

 

General guidelines:

  • K3 Vita-C is used in the water phase of formulations
  • Recommended dosage: 0.1 – 1%
  • Optimum pH range: 1 – 10
  • Temperature: compatible with normal processing temperatures
  • Simple mixing and dissolving into the water phase is sufficient

Benefits and claims in finished products

 

  • Highly stable Vitamin C derivative
