Problems solved by technology

[0003] The purpose of the present invention is to overcome the technical problems of existing sodium soaps such as high irritation, easy formation of calcium soap, low foaming power and poor foam stability, and provide a low-irritation and high-foaming soap formula, that is, a new type of amphoteric The betaine surfactant α-lauryl alkyl betaine (Reference 1) is added to the soap base as an additive to improve the shortcomings of common soaps such as high irritation and low foaming

Embodiment 1

[0015] Example 1 Soap formulation with 2% alpha-lauryl alkyl betaine

[0016] raw material name Mass percentage in formula (%) sodium cocoate 22 α-Lauryl Alkyl Betaine 2 sodium palmitate 70 Sorbitol 2 Di-tert-butyl-p-cresol 0.1 EDTA Disodium Salt 0.1 Titanium dioxide 0.5 Sweet Orange Flavor 0.5 Cayson 0.1 water make up to 100

[0017] When the concentration of the soap used in the experiment is 5%, and the dosage is 0.15mL, the measured skin reaction rating under this condition is 0.81, which belongs to the mild irritation range. The foam performance was measured with a Roche foam meter. The soap concentration was 2.5%, the foam height at 0 min was 170 mm, and the foam height at 5 min was 160 mm.

Embodiment 2

[0019] Example 2 Soap formulation with 5% alpha-lauryl alkyl betaine

[0020] raw material name Mass percentage in formula (%) sodium cocoate 30 α-Lauryl Alkyl Betaine 5 sodium palmitate 60 Sorbitol 2 tert-butyl quinone 0.1 Tetrasodium EDTA 0.05 Titanium dioxide 0.5 lemon zest 1 Cayson 0.05 water make up to 100

[0021] When the concentration of the soap used in the experiment is 5%, and the dosage is 0.15mL, the measured skin reaction rating under this condition is 0.02, which belongs to the non-irritating range. The foam performance was measured by a Roche foam meter. The soap concentration was 2.5%, the foam height at 0 min was 185 mm, and the foam height at 5 min was 160 mm.

Embodiment 3

[0023] Example 3 Soap formulation with 8% alpha-lauryl alkyl betaine

[0024] raw material name Mass percentage in formula (%) sodium cocoate 25 α-Lauryl Alkyl Betaine 8 sodium palmitate 60 Sorbitol 3 tert-butyl quinone 0.5 Tetrasodium EDTA 0.2 Titanium dioxide 0.6 herbal essence 1.0 Cayson 0.05 water make up to 100

[0025] The concentration of the soap solution used in the experiment was 5%, and when the dosage was 0.15mL, the skin reaction grade under this condition was measured as 0.01, which belonged to the non-irritating range. The foam performance was measured with a Roche foam meter. The soap concentration was 2.5%, the foam height at 0 min was 200 mm, and the foam height at 5 min was 175 mm.

Abstract

The invention discloses a low-irritation and high-foaminess fancy soap formula, which is composed of the following components by mass percentage: 2%-10% of alpha-lauryl betaine ampholytic surfactant, 20%-30% of coconut oil sodium salt, 50%-70% of sodium palmitate, 2%-5% of sorbic alcohol, 0.1%-1.5% of antioxidant, 0.05%-0.15% of Kathon, 0.05%-0.2% of chelant, 0.5%-1% of titanium white powder, 0.5%-1.0% of essence and water (the rest). In the fancy soap, the alpha-lauryl betaine ampholytic surfactant is used as additive, which can reduce the irritation of the fancy soap taking the normal sodium soap as the soap base and improve the foaminess of the fancy soap.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a low-irritation and high-foaming soap formula. Background technique [0002] Sodium soap is a natural renewable oil product that is increasingly valued by consumers. However, for bath soaps, ordinary sodium soaps are highly irritating, easy to form calcium soaps, have low foaming power and poor foam stability, and will significantly reduce the foam properties of other surfactants; in fact, sodium soaps are commonly used Defoamer washable in low foam concentrate. Most calcium soap dispersants such as MES or AES and other surfactants can improve the foaming power and foam stability of sodium soap, and can be used in laundry soap; but they cannot effectively improve its irritation at the same time, and the molding effect is not good, so it is not suitable For bath soap formulations. Although the common N-alkyl betaine amphoteric surfactant itself has low irri...
