Description

A kind of foaming cleanser with warm feeling and preparation method thereof

technical field

The present invention relates to a facial cleansing product and a preparation method thereof, and more particularly, the present invention relates to a foaming facial cleanser with a warm feeling and a preparation method thereof.

Background technique

Foaming cleansers have always been the best sellers on the market. The foaming cleanser with a warm feeling will produce a warm feeling during use, thereby promoting the expansion and dredging of pores. While bringing a good experience, it can effectively clean the pores, and with the scrub particles, it can also achieve deep skin Clean function.

In the prior art, a type of warm-feeling cleanser is realized by adding a heat-feeling agent to the cleanser. Common heat-sensing agents include vanillyl butyl, capsaicin, etc. Taking vanillyl butyl ether as an example, the vanillyl group is a functional group that plays a key role in inducing a sense of warmth through the nervous system, and sensory neurons pass through the vanillyl group. Activated by binding to its receptor, known as vanilloid receptor-1 (VR-1). Activated sensory neurons will release glutamate, ATP and various neuropeptides as neurotransmitters at the synapse. These neurotransmitters reach the central nervous system and send out a cascade of warm sensations.

In the prior art, another type of warm-feeling cleanser is realized by adding a thickener to polyalcohol (eg, glycerin, propylene glycol). Polyols have a somewhat cleansing effect on sebum, hydrating and releasing heat upon application. With the thickener, the viscosity of the packaging material such as the suitable hose can be achieved.

However, the current prior art still has certain defects. For example, for the prior art of adding heat-sensing agents to facial cleansers, it will have a strong heat sensation during use, and some users, especially those with sensitive skin, will experience obvious discomfort and stinging sensation during use. Moreover, after washing off these products, the skin can still feel a warm feeling, which will bring discomfort after use.

As for the existing technology that uses polyols to generate heat, although it has a comfortable warm feeling during use, the warm feeling disappears immediately after washing off, which can bring a better use experience. However, due to the main body of this type of product. It is a polyol, only a small amount of water exists, and the system formed by it and the surfactant has poor foaming property, weak cleaning power, and weak suspending force, which is not enough to support the stable suspension of the scrub particles. Therefore, it is difficult to effectively clean the skin. Without the need for exfoliation and deep cleansing, product application has been greatly inhibited.

Therefore, it is necessary to provide a foaming cleanser with a warm feeling, which not only has a good warm feeling during use, does not bring discomfort and tingling during use, but also has good foam performance. , can stably suspend the scrub particles, achieve deep cleansing, exfoliating functions and a good use experience.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a foaming cleanser with a warm feeling, which has a good warm feeling, no discomfort and tingling during use, and can stably suspend the abrasive particles, and has good foam properties.

In order to achieve the above-mentioned purpose of the present invention, the present invention provides a foaming cleanser with a warm feeling, in terms of weight percentage, the cleanser includes the following components:

Surfactant: 3-13%

Suspension thickening polymers in polyols: 0.5-4%

Scrub particles 0.1-4%

water: balance

Wherein, the adopted surfactant is at least one selected from the following group of substances: amino acid surfactant, glycoside surfactant and betaine surfactant;

The polyol used is at least one selected from lower polyols and oligomers thereof.

In the foaming cleanser with a warm feeling of the present invention, the inventors selected amino acid surfactants, glycoside surfactants and/or betaine surfactants, combined with lower polyols and/or oligomers thereof, and A polymer that can suspend and thicken in polyols, the three synergize, not only use the water of polyols to achieve mild heat generation, but also smoothly foam, have sufficient cleaning ability, and at the same time form the stability of abrasive particles. The suspension system overcomes the problems existing in the prior art, and achieves the technical effects of mild heat generation, rich foam, exfoliation (scrub particles) and deep cleaning.

In the warm-feeling foaming cleanser of the present invention, more than 75 wt % of the components are lower polyols and/or oligomers thereof. In this system, the thickener used to increase the suspending ability is different from the thickener used in the general water-based or water-based system. In a sense, these thickeners are some polymer surfactants. The inventors of the present application have found through careful selection and rigorous experimental verification that the polymer that is preferably used in the facial cleanser of the present invention and plays a role in suspending and thickening in polyols is acryloyl dimethyl methyl which has a considerable binding ability to the hydroxyl groups of polyols Copolymers or homopolymers of taurine or salts.
