example i
[0310]The exemplary embodiment describes a formulation and a preparation method thereof disclosed herein.
[0311]2.38 g of hydrogenated phospholipid, 0.12 g of sterol, 0.4 g of methyl paraben, 0.2 g of ethyl paraben and 0.1 g of menthol were weighed and placed in a beaker. 1 mL of anhydrous ethanol was added and dissolved with ultrasonic (40 KHz). While mixing at a high-speed stirring (6000 rpm), water was continuously added till the final volume of 100 mL, and mixed well. The formulation was filled into a containment vessel, such as sprayer or a dropping device, and the containment vessel was sealed. After the results of appearance, volume, content of main ingredient, weight per spray (or weight per drop), microbial limit and other tests were found to meet the requirements, outside packaging was performed to obtain the final product.
[0312]The surface tension of a final product was tested to be 48.851 mN / m by an automatic surface tensionmeter (US Kino, A601). The particle size distrib...

[0314]The exemplary embodiment describes a formulation and a preparation method thereof disclosed herein.
[0315]2.35 g of soya lecithin, 0.15 g of poloxamer, 0.08 g of vitamin E and 0.5 g of phenylethanol were weighed and placed in a beaker. 1 mL of anhydrous ethanol was added and dissolved with ultrasonic (40 KHz). While mixing at high speed (6000 rpm), water was continuously added till the final volume of 100 mL, and mixed well. The formulation was filled into a containment vessel, such as sprayer or a dropping device and the containment vessel was sealed. After the results of appearance, volume, content of main ingredient, weight per spray (or weight per drop), microbial limit and other tests were found to meet the requirements, outside packaging was performed for preparation to obtain the final product.
[0316]The surface tension of a final product was tested to be 16.252 mN / m by an automatic surface tensionmeter (US Kino, A601). The particle size distribution of the product was de...

[0318]The exemplary embodiment describes a formulation and a preparation method thereof disclosed herein.
[0319]3.75 g of soya lecithin and 0.64 g of vitamin E were weighed and placed in a beaker. 1 mL of anhydrous ethanol was added and dissolved with ultrasonic (40 KHz). The ethanol solution was added into 0.05 g of lauric acid monoglyceride and 99 mL of Tris-citric acid buffer solution with the pH in the range of 6.0-7.4 while a high-speed stirring (6000 rpm). The ultrasonic homogenization was further performed in an ultrasonic homogenizer. Then, the formulation was filled into containment vessel, such as an anti-contamination medicine delivery device (OSD) and sealed. After the results of appearance, volume, content of main ingredient, weight per spray (or weight per drop), microbial limit and other tests were found to meet the requirements, outside packaging was performed to obtain the final product.
[0320]The surface tension of a final product was tested to be 26.225 mN / m by an a...
