Technical Field

The invention relates to the field of cosmetic skin care, in particular to a wet self-heating facial mask and a preparation method thereof.

Background

With the improvement of living standard, the facial mask becomes a necessary beauty and skin care product for a plurality of women. The facial mask can achieve various effects of whitening, moisturizing, improving pigmentation, cleaning pores, regulating grease balance and the like. The heating mask can slowly expand pores, promote secretion of sweat glands, accelerate blood circulation of deep skin, increase activity of epidermal skin cells, and facilitate full absorption of nutrient components in mask essence by facial skin, so that the mask is deep-cleaned and has bright skin color.

In order to increase the temperature of the mask, the simplest method is to soak the mask in warm water or steam the mask with steam, so that when the mask is applied to the face, facial pores are better opened, pollution discharge is promoted, and the beauty effect is enhanced. However, such methods of use are cumbersome and time consuming and have limited effectiveness.

For this reason, various technical solutions of heat-generating facial masks are proposed in the prior art, such as:

the Chinese utility model 201821969929.5 discloses an ultrathin flexible heating facial mask, which comprises a facial mask body, wherein the facial mask body is sequentially provided with an insulating layer, a bonding layer, a conductive heating layer, a bonding layer and an insulating layer from top to bottom; wherein a USB power interface is arranged below the mask body. The utility model discloses an electric heating facial mask which needs to be connected with a power supply when in use.

The graphene film is an electrothermal mask by utilizing the characteristics of moderate resistivity, extremely high thermal conductivity, good thermal stability and easiness in processing and forming of the graphene film, and needs to be connected with a power supply when in use.

The Chinese invention application 201710724107.4 discloses a heating mask with mask base cloth and mask essence, wherein each 100 parts by weight of the mask essence comprises 0.001-1.0 part by weight of a heating agent combination, 1-30 parts by weight of a humectant, 0.01-1.0 part by weight of a thickening agent, 0.01-0.05 part by weight of an active component, 0.1-5.0 parts by weight of a cosmetically acceptable carrier, and the balance of distilled water, wherein the heating agent combination comprises a heat sensing agent and an auxiliary heating agent, the heat sensing agent is vanillyl butyl ether, the auxiliary heating agent is one or two combinations of wild mountain chicken pepper fruit oil and star anise seed oil, and the mass ratio of the heat sensing agent to the auxiliary heating agent is 10: 1. In the application, the thermal sensation agent vanillyl butyl ether belongs to nerve ending stimulation substances, has uncontrollable heating intensity and strong skin irritation, and is not suitable for consumers with sensitive skin.

The Chinese patent application 201710191258.8 discloses a heating facial mask and a preparation method thereof, wherein the heating facial mask sequentially consists of facial mask paper (1), an acid heat release layer (2) and an alkali heat release layer (3); wherein a first isolation layer (5) is arranged between the mask paper (1) and the acid heat release layer (2), a second isolation layer (7) with a tearing tie (6) is arranged between the acid heat release layer (2) and the alkali heat release layer (3), and a non-woven fabric (4) internally attached with a plastic film is arranged on the other side of the alkali heat release layer (3). Both acid and alkali can irritate and even corrode the skin to some extent, and care must be taken when using the composition.

The Chinese patent application 201510151986.7 (abandoned) discloses a heating facial mask which comprises a seven-layer structure, wherein a sealing layer, a breathable layer, a heating layer, a water-proof heat-preservation layer, a functional layer, a membrane layer and a waterproof layer are respectively arranged from outside to inside. Wherein the heat generating layer includes a first heat generating layer and a second heat generating layer, each loaded with a heat generating compound that generates heat by contact with air. The heat-generating compound includes oxidizable metal, activated carbon, inorganic metal salt, water, humectant and water absorbent. For example, the heat-generating compound of the first heat-generating layer thereof may include, in mass percent: 45-50% of iron powder, 3-5% of silica fume, 8-10% of activated carbon, 5-8% of salt, 10-15% of vermiculite, 3-7% of water-absorbent resin, 10-15% of water and 5-8% of attapulgite, and the heat-generating compound of the second heat-generating layer can comprise the following components in percentage by mass: 35-40% of iron powder, 5-7% of silica fume, 12-15% of activated carbon, 2-4% of salt, 10-15% of vermiculite, 1-3% of water-absorbent resin, 15-20% of water and 5-8% of attapulgite.

The self-heating type beauty mask mainly comprises the following components in percentage by mass: (a) 1-5 wt% of sodium alginate; (b) 0.5-20 wt% coagulant; (c) 1-10 wt% of zeolite; (d) the balance of filler. The dry heating mask utilizes the principle that zeolite heats when meeting water, but has the problems that zeolite quickly heats when meeting water and the controllability is poor.

Thus, although the heating facial mask in the prior art has various characteristics, the heating facial mask also has the defects. Therefore, there is a need for a self-heating facial mask which is convenient to use, does not need to be connected with an external power supply, is safe and reliable, does not stimulate nerve endings, generates heat mildly, has long heating time, and can adjust the heating intensity according to the requirements.

Disclosure of Invention

The invention aims to provide a heating mask and a preparation method thereof, aiming at solving the defects of the prior art, the heating mask adopts synthetic zeolite powder and/or natural zeolite powder which can generate heat when meeting water as a heat sensing agent, and selects a polyol system as a carrier of zeolite, so that the heating intensity can be adjusted according to the requirement.

In order to achieve the above object of the present invention, the present invention provides a wet heat-generating mask comprising an emulsion to cream-like substance formed from:

In the above-described embodiment of the present invention, the synthetic zeolite powder and/or the natural zeolite powder is first dispersed in the polyol. Since the hydroxyl group in the organic alcohol is connected with the carbon chain and is inactive, the organic alcohol can be bonded with the zeolite, but the bonding force is not strong. When zeolite dispersed in organic alcohol encounters water, the organic alcohol molecules in the cavities of the zeolite are displaced by the water molecules to release heat due to the high activity of the hydroxyl groups in the water molecules and the high affinity to the zeolite. In this way, in the present invention, the length of heat generation and the intensity of heat generation can be adjusted by controlling the type and content of the alcohol used as the zeolite carrier, controlling the amount of water remaining after the washing of the part, and controlling the zeolite content in the wet heating mask.
