Experimental example 2
The experimental example detects the service performance of the composite hand sanitizer for industrial heavy oil stain removal obtained in the examples 1 to 3, and detects the heavy oil stain removal performance of the composite hand sanitizer.
The experimental contents are as follows: randomly selecting 40 workers engaged in machine repair and automobile repair as volunteers to be tested, smearing simulated oil stains on clean and dry hands, wherein the amount of the smeared films is 2 g/two hands (marked as initial heavy oil stain), standing for 10min at normal temperature, and waiting for cleaning. The simulated oil stain is a mixture of mechanical punching oil, lubricating oil and dust in a mass ratio of 1:1:0.2 and is used for simulating heavy oil stain.
The cleaning process simulates the use process of the conventional hand sanitizer: in the experimental group, each person firstly wets hands with water, places the decontamination cleaning agent in the composite hand sanitizer obtained in the embodiment at the palm, rubs the hands with the dosage of 0.6 g/hand to form foam, then carefully rubs the hands for 30s according to the sequence of palm center to palm center, palm center to palm back, finger joint to finger joint and finger abdomen to palm center, washes with water, and marks as one-time cleaning; the skin care detergent in the composite hand sanitizer obtained in the example is put into the palm of a hand, the dosage of the skin care detergent is 0.6g per hand, the skin care detergent is kneaded to foam, and then the skin care detergent is kneaded carefully for 30 seconds in the same sequence, and the skin care detergent is washed by water and marked as secondary cleaning. The experimental groups 1 to 3 respectively adopt the compound hand sanitizer obtained in the embodiments 1 to 3; the comparative example was washed twice with a commercial industrial degreasing liquid soap (a Tibet liquid soap), and the specific procedures and amounts were as above.
And cleaning hands of the experimental group and the comparative example, naturally airing, soaking by using ethanol, thoroughly cleaning two hands, collecting ethanol washing liquor, concentrating, performing rotary evaporation, collecting residues, weighing and calculating, and recording as the residual oil stain amount.
