[0044] Preparation

[0045] The preparation methods of Examples 1, 2, and 5 are as follows: Slowly add carbomer to some deionized water to make it completely wet, then stir until there are no particles, then add neutralizer and stir until transpa...

Embodiment 6

[0047] Example 6 can be produced by this pre-dissolving method, and its preparation method is as follows: pre-mix and dissolve sodium pyrrolidone carboxylate, cocamidopropyl betaine and part of sodium lauryl polyoxyethylene ether sulfate (70%) with essence It becomes a gel for later use, then slowly add carbomer into some deionized water to make it completely wet, stir until there are no particles, then add neutralizer and stir until transparent, and finally add sodium lauryl polyoxyethylene ether sulfate (70% ), sodium lauryl sulfate, ethylene glycol distearate, cocoyl monoethanolamine, methyl p-hydroxybenzoate, propyl p-hydroxybenzoate, heat up to 75~80°C and keep stirring to dissolve completely . When the temperature is lowered below 50°C, EDTA-2Na aqueous solution, sodium chloride aqueous solution, DMDM ​​hydantoin, sodium pyrrolidone carboxylate, cocamidopropyl betaine and part of sodium lauryl polyoxyethylene ether sulfate (70 %) is pre-mixed with the essence to dissolv...

Abstract

The invention discloses a washing personal skin cleaning composition and a preparation method thereof. The formula comprises a cleaning matrix, a wetting agent and volatile essence, wherein the water-soluble wetting agent in the formula is 0.1-20 weight percent, and the volatile essence is 0.001-8 percent. The preparation method comprises the following steps of: preparing the cleaning matrix, and adding the wetting agent and the volatile essence; or respectively preparing the cleaning matrix and a premixture of the wetting agent and the volatile essence, and mixing the mixing the cleaning matrix and the premixture. The formula and the preparation process are improved, the deposition of the volatile components in the personal skin cleaning composition to the skin is prompted by using the wetting agent or a fat agent, the retention time of the components on the skin is increased, and irritation brought to the skin is avoided.

Description

technical field [0001] The invention relates to the field of personal care products, in particular to a wash-off personal skin cleansing composition and a preparation method thereof. The composition can promote the deposition of fragrance on the skin and the delivery of fragrance on the skin surface. Background technique [0002] Perfumes and fragrances are often added to rinse-off personal cleansing compositions to impart a fresh, clean feel to the composition. Many users prefer that the fragrance deposits from the composition onto their skin and stays on for a period of time to provide a constant fresh feeling. However, due to the volatility of many fragrances, it is difficult for users to achieve this beneficial effect. Cationic deposition polymers have been used in the past to facilitate deposition of certain nonvolatile ingredients in personal cleansing compositions to the skin. However, it promotes the deposition of volatile ingredients (such as essence) and increase...
