In this paper, vegetable oils (75 grams of coconut oil and 75 grams of palm oil) and lye (NaOH and water will depend on the addition of all vegetable oil saponification values to change) as the main raw material, and olive oil and shea butter Control factor.

The recipe for finding the best handmade soap is based on the above main material and is added with shea butter and indigo powder. The use of skin detector to detect skin oil, skin elasticity and moisturizing degree of data that A / 20% hand soap, B / 20% soap base oil is higher, the skin moisturizing lock water capacity, moisture Have a very good effect. And then the skin type test with a shallow 50-fold skin condition detector and a deep 50-fold skin condition tester and a 200-fold skin care device.
