The chemical name of glycerol is glycerol glycerol, which has a sweet taste and is a colorless, transparent, viscous liquid. It is a product produced by chemical industry and has good water absorbency. It is commonly used as a raw material for cosmetics.
method:
Prepare a standard curve, accurately weighed the appropriate amount of glycerol, add water to make 28.00%, 29.00%, 30.00%, 31.00%, 32.00% (concentrations are g/V), and use the refractive method to determine its refractive index at t=20°C. Rate [1], the results are shown in the following table:
in conclusion:
ATAGO Refraction Desktop glycerol refractometer RX-9000a, (economy) digital glycerol refractive index Abbe refractometer DR-A1, hand-held digital glycerol concentration meter PAL-23S, portable glycerol refractometer PAL -24S, determination of 30% glycerol skin care water glycerol content, speed, ease of operation, the results consistent with the iodometric method.

The refractometry method is one of the rapid tests for hospital preparations. The glycerin skin care water is a regular formulation for hospitals. The classical method for determining the legal content is the iodine method. Iodometric method requires sodium thiosulfate standard solution and a variety of reagents, and time-consuming. Glycerine skin care water is a transparent liquid, high glycerol content, glycerol has a strong refractive index, in line with the refractive index content determination. The content determination by refractometry does not require sodium thiosulfate standard solution and multiple reagents, and no energy is needed to avoid the disadvantages of the iodometric method and increase the measurement efficiency. The results are consistent with the iodometric method.
