Description

Non-irritating shampoo bath lotion and preparation method thereof

Technical Field

The invention relates to the field of daily necessities, in particular to a non-irritating shampoo and bath lotion and a preparation method thereof.

Background

Along with the faster and faster pace of life, the demands for daily necessities are gradually increased, and particularly for washing products, people need to purchase two products, namely shampoo and bath lotion, to be used separately based on different washing parts, but for special users (infants or children who need to wash hair and body simultaneously during bath), the two products are hoped to be combined. In addition, the shampoo bath product and the foam generated by the shampoo bath product are easy to permeate into eyes when infants or children are shampooed, and if the shampoo bath product has irritation, the infants or children which do not complete development can be stimulated or injured.

The two-in-one shampoo and bath lotion products existing in the market at present are mainly divided into two categories: the first category is products containing sodium laureth sulfate, ammonium C12-15 alkanolpolyether sulfate, cocamide DEA, cocamide MEA and other substances, the products have low preparation cost and rich foam generally, but have strong degreasing power, the skin is easy to dry after use, and the irritation to the skin and eyes is strong; the second category is products containing decyl glucoside, lauryl glucoside, sodium lauroyl sarcosinate, sodium methyl cocoyl taurate, PEG-80 sorbitan laurate, etc. and surfactants, which are less irritating, but generally lower in viscosity, and less foaming, so that the products are generally required to be used with foam pumps, but the cost of the foam pumps is relatively high, resulting in relatively high price of the products. In addition, most of the two-in-one products for washing and bathing in the market at present have fresh, effective and continuous moisturizing performance.

Disclosure of Invention

Based on the defects existing in the prior art, the invention aims to provide the non-irritating shampoo and bath lotion, which has the effects of bathing and shampooing, and shows excellent mildness and non-irritating property through reasonable collocation of the components, and has good foaming effect, proper consistency and good skin feel experience in the use process, and good washing effect on bodies and hair.

In order to achieve the above purpose, the invention adopts the following technical scheme:

the non-irritating shampoo bath lotion comprises the following components in parts by weight:

3 to 5 parts of PEG-80 sorbitan laurate, 0.5 to 2 parts of cocamidopropyl betaine, 3 to 5 parts of laurylglucoside, 0.9 to 5 parts of potassium cocoyl hydrolyzed oat protein, 0.5 to 2 parts of sodium lauryl glucose carboxylate, 0.5 to 2 parts of 2-disodium sulfolaurate, 0.63 to 0.68 part of PEG/PPG-120/10 trimethylolpropane trioleate, 0.63 to 0.68 part of laureth-2, 0.6 to 1.45 parts of PEG-150 stearate and 0.03 to 0.1 part of hair conditioner.

In the components of the non-irritating shampoo and bath lotion, the PEG-80 sorbitan laurate has a larger molecular weight, so that the irritation is lower in a system compared with other surfactants, the critical micelle concentration of a product system can be effectively reduced by introducing the components, the content of free surfactants is reduced, and the irritation can be further reduced. In addition, compared with the anionic surfactant, the nonionic surfactant and the amphoteric surfactant contained in the product component, the product component can quickly migrate to the skin or the mucous membrane surface during use, and direct contact of other surfactants or hair conditioning agents to the skin or the mucous membrane is avoided, so that the product can achieve a non-irritating effect under the condition of abundant foaming, and has good stability during the storage process or the use process.

On the other hand, the components of cocamidopropyl betaine, lauryl glucoside, potassium cocoyl hydrolyzed oat protein, sodium lauryl glucose carboxylate and disodium 2-sulfolaurate have the effect of synergistically increasing the foaming effect, wherein the potassium cocoyl hydrolyzed oat protein can improve the foaming effect of the product in hard water, and the mildness of the product can synergistically reduce the irritation of the whole product; the mutual collocation of the lauryl glucoside and the sodium lauryl glucose carboxylate can enable the foam emitted by the product to be compact and creamy, and the skin is softer and smoother after the use.

In the components of the product, PEG/PPG-120/10 trimethylolpropane trioleate has larger molecular weight, can be connected with micelles formed in a product system and build larger micelle groups, and PEG-150 stearate can form a three-dimensional hydration network in a water phase, and the two components are matched to effectively form a micelle network which is enough to cover each surfactant; laureth-2 can form rod-shaped micelle in a system, the micelle has higher morphological stability, and the obtained product has good thickening effect through the synergistic combination of the three components.

The product overcomes the defect that the existing two-in-one shampoo and bath product cannot give consideration to optimal bath and shampoo effects, has good washing effect, and has the characteristics of no stimulation, good stability, good foaming effect and good use experience.

Preferably, the hair conditioner is polyquaternium-10.
