Abstract

The invention relates to a nanometer water-based gel and a preparation process thereof. The nanometer water-based gel is prepared from the following raw materials in part by weight: 240 to 410 parts of water, 130 to 280 parts of glycerol, 54 to 99 parts of propylene glycol, 113 to 248 parts of carbomer, 10 to 45 parts of gelatin, 22 to 65 parts of starch, 12 to 48 parts of laurinol polyoxyethylene ether and 5 to 14 parts of nanometer silicon dioxide. The nanometer water-based gel is smooth in appearance, beautiful in shapes and transparent and fine, is appropriate in consistence and viscosity, easy to coat and stable in properties, is not compatible with main medicaments, does not obstruct the normal function of skin, has the excellent performance of medicament release, has high safety, is inirritative locally and easy to clean, does not pollute clothes, keeps colloidal and is not dried up or liquefied at normal temperature, and has controllable quality and a simple preparation process.

Science, and technical science with nanoengineering and processing as the main line. It is undeniable that nanoscience and technology is a complete system integrating scientific frontiers and high technology. Nanotechnology mainly ...

Examples

Embodiment 1

[0014] Prepared from the following raw materials in parts by weight, water: glycerin: propylene glycol: carbomer: gelatin: starch: polyoxyethylene lauryl ether: nano silicon dioxide = 325: 202: 75: 165: 30: 26 :20:9.

[0015] The preparation process of the present invention is as follows:

[0016] Moisten the carbomer with water, ethanol, glycerin and propylene glycol according to the above ratio of parts by weight to avoid flying dust, and then gradually add water to swell; then add the rest of the raw materials and mix evenly, and grind until uniform.
