Problems solved by technology
[0003] The outermost layer of the skin is a layer of sebum film that is thinner than the plastic wrap. Soaps with a high pH value will damage the skin sebum film, make the skin lose its protective ability, and cannot store enough water, which will easily cause skin aging, dryness, itching and allergies
Therefore, the use of products with too strong alkalinity will cause a large loss of sebum, reduce the alkali neutralization ability of the skin, and cause skin damage

Embodiment
[0013] A handmade soap soap base formula, composed of the following raw materials by weight percentage: 14% octadecanoic acid, 5% dodecanoic acid, 6% glycerin, 10% surfactant, 8% alcohol, 14.47% sorbitol, 7% propylene glycol , alkali 3.03%, water 7.5% and cosmetic grade sucrose 25%.
[0014] A preparation method of handmade soap soap base, comprising the following steps:
[0015] A Stirring: put octadecanoic acid, lauric acid, glycerin, surfactant, alcohol, sorbitol and propylene glycol into a pot, heat and stir together according to the weight ratio of raw materials, and keep the stirring speed at 20r / min to 65°C to obtain a transparent soap material. Alkali and water are fully mixed and stirred to obtain an alkali-water mixture for subsequent use;
[0016] B Saponification: Add the prepared alkali-water mixture to the transparent soap material, and speed up the stirring at 35r / min to make the transparent soap material fully formed;
[0017] C completion: continue to heat u...

The invention discloses a handmade soap base formula and a handmade soap base preparation method, wherein the raw materials comprise, by weight, 10-20% of octadecanoic acid, 2-8% of dodecanoic acid, 3-10% of glycerol, 5-20% of a surfactant, 4-11% of alcohol, 10-20% of sorbitol, 5-10% of propylene glycol, 1-7% of an alkali, 4-11% of water, and 20-30% of cosmetic-grade sucrose, and the preparation method comprises: A, stirring, B, saponification, and C, completion. Compared with the soap base in the prior art, the soap base of the present invention has the following characteristics that the cleaning ability is strong while the pH value is maintained at close to the human skin, the pH value is controlled at 6.8-7.5, and the moisturizing effect is substantially increased compared with the soap base in the prior art.
Description
technical field [0001] The invention relates to the technical field of soap, in particular to a handmade soap soap base formula and a preparation method thereof. Background technique [0002] As we all know, the minimum pH value of human skin is 4.0, the highest can reach 9.6, and the average is between 5.0-7.0. The pH value of soap products for bathing is as high as 10.57. [0003] The outermost layer of the skin is a layer of sebum film that is thinner than the plastic wrap. Soap with a high pH value will damage the skin sebum film, making the skin lose its protective ability, unable to store enough water, and easily cause skin aging, dryness, itching and allergies. Therefore, the use of products with too strong alkalinity will cause a large amount of sebum loss, which will reduce the alkali neutralization ability of the skin and cause skin damage. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above te...
