TLDR
Ascorbic acid was relatively stable in glycerin and propylene glycol and in sugar and sorbitol solutions and in syrups containing conjointly vitamins of the B‐complex is not materially affected.Abstract:
The stability of ascorbic acid at several concentrations in various liquid media including aqueous solutions of cellulose gums, pectin, sucrose, dextrose, corn syrup, and in glycerin and propylene glycol was studied The effect of p H in aqueous solutions of ascorbic acid was also studied Viscosity alone as produced by gums did not prevent decomposition of ascorbic acid Sugar and sorbitol solutions exerted a marked stabilizing effect Ascorbic acid was relatively stable in glycerin and propylene glycol and in sugar and sorbitol solutions Data are presented on the rates of decomposition of ascorbic acid in these media after storage at room temperature and at 40°C The stability of ascorbic acid in syrups containing conjointly vitamins of the B‐complex is not materially affectedread more

Enhancement of Ultra-violet Absorption of L-Ascorbic Acid in the Presence of D-Sorbitol
TL;DR: Ascorbic acid in presence of various concentrations of D-sorbitol shows a considerable increase of its characteristic absorption peak both in neutral aqueous solution and in acidic solution, indicating an unusual enhancement of its ultra-violet absorption.

Detection of vitamin C in various falsified oral formulations using voltammetry
TL;DR: In this paper, the authors used voltammetry to identify the concentration of vitamin C present and the type of oral formulation of various falsified healthcare supplements without the need for any sample analysis and found that tablet excipients reduce the oxidation peak current and influence the peak shape and oxidation peak potentials.

Compositions and methods for the treatment of skin
TL;DR: An ascorbic acid-based composition and related method for the treatment of aging, photo-damaged or inflamed skin is disclosed in this article, which includes water and a portion of which has generally been pretreated by being dissolved under relatively high temperature and concentration conditions.
