Description

Cleaning massage shower gel and preparation method thereof
Technical Field
The invention relates to the field of washing and caring products, in particular to a cleaning and massaging bath cream and a preparation method thereof.
Background
At present, a chemically synthesized surfactant is mostly adopted in the shower gel to play a role in deoiling and cleaning, but due to strong alkalinity, the shower gel can generate irritation to skin and even cause anaphylactic reaction; some shower gel adopts activated carbon to replace a chemically synthesized surfactant to a certain extent, and the porous property of the activated carbon is utilized to absorb oil stains, sweat stains, human body secretions and the like, so that the shower gel has a cleaning effect. For example, patent document CN202011044137.9 discloses an oil-controlling and soothing body wash and a preparation method thereof, wherein the body wash is prepared by compounding natural plant massage extract, bio-based surfactant and biomass activated carbon, and plays roles of controlling oil and regulating water-oil balance of skin together. However, although activated carbon can promote the removal of body surface stains by utilizing the excellent adsorption capacity and the friction mechanical effect, the activated carbon has poor comfort and is easy to cause skin abrasion when being applied to the skin due to high hardness and surface roughness of the activated carbon.
Disclosure of Invention
In order to solve the technical problems, the invention provides a cleansing massage bath lotion and a preparation method thereof. The cleaning massage bath cream adopts cleaning massage particles with unique structures, has good oil removal, cutin removal and massage effects, and can not cause damage to skin.
The specific technical scheme of the invention is as follows:
the cleaning massage bath cream comprises the following components in parts by weight: 3-4 parts of mother chrysanthemum extract, 0.5-2.5 parts of citron fruit peel extract, 1-2 parts of chlorella extract, 2-3 parts of tea saponin, 4.5-5.5 parts of alkyl glycoside, 1-2 parts of wood particles, 3-4 parts of cleaning massage particles, 0.1-0.3 part of disodium edetate, 0.05-0.1 part of sodium benzoate and 60-70 parts of water; the cleaning massage particles comprise an activated carbon core layer and a porous zein/polylactic acid composite coating layer coated outside the activated carbon core layer.
In the cleaning massage particles, the activated carbon core can play a role in removing oil by utilizing higher porosity, and the cleaning massage particles can play roles in massaging and removing cutin in the repeated smearing process of the shower gel. However, the active carbon with hard texture and rough surface is easy to cause skin damage when being directly contacted with the skin, therefore, the invention adopts the porous zein/polylactic acid to coat the active carbon, the polymer composite coating layer can endow the cleaning massage particles with smooth and softer surface, and can avoid the direct contact of the active carbon and the skin; in addition, in the composite coating layer, the zein and the polylactic acid both have higher hydrophobicity, so that the zein and the polylactic acid have an adsorption effect on oil stains, and the porous structure of the coating layer can ensure that the zein and the polylactic acid do not excessively influence the adsorption function of the activated carbon.
Preferably, the particle size of the cleaning massage particles is 80-120 μm, and the diameter of the activated carbon core layer is 40-50 μm.
Preferably, the preparation method of the cleaning massage particles is as follows:
(A) respectively dispersing polylactic acid and zein into water to prepare polylactic acid dispersion liquid and zein dispersion liquid; adding activated carbon into the polylactic acid dispersion liquid, after uniform dispersion, dropwise adding the zein dispersion liquid under stirring, continuously stirring for 40-60min, and filtering to obtain activated carbon @ zein/polylactic acid particles;
(B) and carrying out vacuum microwave treatment on the active carbon @ zein/polylactic acid particles, and then carrying out vacuum drying to obtain the clean massage particles.
After the active carbon @ zein/polylactic acid granules are prepared, the active carbon @ zein/polylactic acid granules are subjected to vacuum microwave treatment, air in the active carbon is vibrated to escape under the action of air pressure difference between the inside and outside of the granules and microwaves, and pores are formed in the zein/polylactic acid coating layer, so that the excessive influence of the coating layer on the adsorption effect of the active carbon is prevented.
In the composite coating layer, the polylactic acid has higher air permeability, and molecular chains of the polylactic acid form a net structure through physical entanglement, so that the polylactic acid is easily influenced by escaping air during vacuum microwave treatment to form larger pores; the zein molecular chains are crosslinked through hydrogen bonds and disulfide bonds, so that a zein/polylactic acid crosslinking network has certain mechanical strength, and a coating layer is prevented from being damaged in the preparation and use processes of the shower gel. Therefore, the invention adopts polylactic acid and zein to clad in a composite way, so that the cladding layer can form larger pores during vacuum microwave treatment and has higher mechanical strength, thereby endowing the cleaning massage particles with better oil removal function and effectively preventing the cleaning massage particles from damaging the skin.
Preferably, in step (A), the solid contents of the polylactic acid dispersion and the zein dispersion are 10 to 15 wt% and 6 to 8 wt%, respectively.
Preferably, in the step (A), the mass ratio of the polylactic acid to the zein to the activated carbon is 1.5-2.5:1: 0.5-1.
During the coating process, the amount of polylactic acid and zein can affect the function of the cleaning massage particles: if the consumption of the zein is too large, larger pores are difficult to form during vacuum microwave treatment, and the oil removal effect of the cleaning massage particles is not ideal; if the relative dosage of the polylactic acid is too large, the mechanical strength of the coating layer is too low, the coating layer is damaged in the preparation and use processes of the shower gel, and the rough surface of the active carbon is damaged after contacting with the skin.
Preferably, in the step (B), the vacuum degree of the vacuum microwave treatment is 0.03-0.05MPa, the power is 500-600W, and the treatment time is 15-25 min.
Preferably, the cleansing massage bath cream also comprises the following components in parts by weight: 1-2 parts of wood particles.
In wooden granule, because the unique fan-shaped structure of wood fibre, can give wooden granule higher porosity, make it can adsorb the greasy dirt of body surface, simultaneously, wooden granule can exert the effect of getting rid of cutin through the friction mechanical effect, and because its soft texture, can avoid causing the damage to skin, and play the massage effect.
The soft texture can give better massage effect to the wood particles, but simultaneously, the pores are easy to deform and shrink in the using process, which is not beneficial to the absorption of oil stains; the active carbon in the core layer of the cleaning massage particles is not easy to deform, can keep better oil removal effect, but can also cause higher hardness of the cleaning massage particles and relatively poorer massage effect. Therefore, the shower gel provided by the invention has good cleaning and massaging functions by compounding the wood particles and the cleaning and massaging particles.
Preferably, the preparation method of the wood particles comprises the following steps: pulverizing wood into particles with particle size of 50-100 μm, and loosening at 180 deg.C and 0.5-0.8MPa for 40-80min to obtain wood particles.
At high temperature, water in the wood particles is evaporated, and at the same time, the cellulose is partially decomposed thermally, so that the wood particles are loose and soft in texture, the skin is not damaged, and the adsorption performance is better.
A method for preparing the cleansing massage bath cream comprises the following steps:
(1) heating water, maintaining the temperature at 65-75 deg.C, adding tea saponin and alkyl glycoside, mixing, adding cleaning massage particles, and mixing to obtain primary mixed solution;
(2) cooling the primary mixed liquid to 42-46 ℃, adding the chamomile extract, the citron fruit peel extract and the chlorella extract, mixing uniformly, adding the disodium edetate and the sodium benzoate, and fully mixing to obtain the cleaning massage bath cream.
A method for preparing the cleansing massage bath cream comprises the following steps:
(1) adding the wood particles into a part of water, and heating for 1-2h at 80-90 ℃ to obtain wood particle dispersion liquid;
(2) heating the rest water, maintaining the temperature at 65-75 deg.C, adding tea saponin and alkyl glycoside, mixing, adding wood particle dispersion liquid and cleaning massage particles, and mixing to obtain primary mixed liquid;
(3) cooling the primary mixed liquid to 42-46 ℃, adding the chamomile extract, the citron fruit peel extract and the chlorella extract, mixing uniformly, adding the disodium edetate and the sodium benzoate, and fully mixing to obtain the cleaning massage bath cream.
Preferably, in the step (1), the mass ratio of the wood particles to the water is 1: 10-15.
Compared with the prior art, the invention has the following advantages:
(1) in the cleaning massage particles, the porous zein/polylactic acid is adopted to coat the active carbon, so that the active carbon can be prevented from damaging the skin, the cleaning massage particles have better massaging and cutin removing effects, and the oil removing effect of the active carbon cannot be adversely affected;
(2) in the cleaning massage particles, the zein and the polylactic acid are compounded and coated in a certain proportion, so that the coating layer has larger pores and higher mechanical strength, thereby endowing the cleaning massage particles with better deoiling function and effectively preventing the cleaning massage particles from damaging the skin;

(1.1) respectively dispersing polylactic acid and zein into water to prepare polylactic acid dispersion liquid and zein dispersion liquid with solid contents of 15 wt% and 6 wt%, respectively; adding active carbon with the particle size of 40-50 mu m into polylactic acid dispersion liquid, uniformly dispersing, dropwise adding zein dispersion liquid under stirring, continuously stirring for 60min, and filtering to obtain active carbon @ zein/polylactic acid particles, wherein the mass ratio of polylactic acid to zein to active carbon is 2.5:1: 1;
(1.2) carrying out vacuum microwave treatment on the activated carbon @ zein/polylactic acid particles, wherein the vacuum degree is 0.05MPa, the power is 600W, the treatment time is 15min, and then carrying out vacuum drying to obtain clean massage particles with the particle size of 80-120 microns;
(2) preparing wood particles: pulverizing wood into particles with particle size of 50-100 μm, and loosening at 175 deg.C under 0.6MPa for 1 hr to obtain wood particles;
(3) adding wood particles into a part of water, wherein the mass ratio of the wood particles to the water is 1:10, and heating for 1.5 hours at 85 ℃ to obtain wood particle dispersion liquid;
(4) heating the rest water and maintaining at 75 deg.C, adding tea saponin and alkyl glycoside, mixing, adding wood particle dispersion liquid and cleaning massage particles, and mixing to obtain primary mixed liquid;
(5) cooling the primary mixed liquid to 46 ℃, adding the chamomile extract, the citron fruit peel extract and the chlorella extract, mixing uniformly, adding the disodium ethylenediamine tetraacetic acid and the sodium benzoate, and fully mixing to obtain the cleaning massage bath cream.
Comparative example 1
This comparative example is different from example 1 in that the cleaning massage particles are replaced with an equal mass of activated carbon having a particle size of 80 to 120 μm.
Comparative example 2
This comparative example differs from example 1 in that step (1.2) is not carried out.
Comparative example 3
This comparative example differs from example 1 in that in step (1.1) the polylactic acid is exchanged for zein of equal mass.
Comparative example 4
This comparative example differs from example 1 in that in step (1.1) zein is replaced by polylactic acid of equal mass.
Comparative example 5
The difference between the comparative example and the example 2 is that in the step (1.1), the mass ratio of the polylactic acid to the zein to the activated carbon is 2:1: 0.8.
Comparative example 5
The difference between the comparative example and example 3 is that in step (1.1), the mass ratio of polylactic acid, zein and activated carbon is 2.5:1: 1.
The test was performed on the body washes of examples 1-4 and comparative examples 1-4, respectively, by randomly dividing 80 subjects between 20-40 years of age into 8 groups, and the test items and methods were as follows:
(1) the oil removal effect is as follows: respectively testing the skin oil content of the inner side of the forearm of the testee before and after the shower gel is used, calculating the reduction rate of the skin oil content of each tester, and averaging each group;
(2) exfoliating effect: before use, the inner forearm of each subject was tested for skin roughness; after using the shower gel for 30 days (the using period is once a day), detecting the skin roughness of the anterior and medial sides of each subject again, calculating the reduction rate, and taking the average value of each group;
(3) sensory evaluation: taking 1-2g of shower gel, massaging the inner side of the forearm of a subject for 2min, scoring the skin pain condition, wherein 0 score represents no pain, 10 scores represents that the pain is very obvious, and averaging values are taken for each group.
The test results are shown in Table 1.
TABLE 1
Figure BDA0003055184430000071
Figure BDA0003055184430000081
The test results of comparative example 1 and comparative example 1 show that: after the surface of the active carbon is coated with the zein/polylactic acid composite coating layer, the pain is obviously weakened, and the deoiling effect is not obviously reduced. The reason is that: the active carbon with hard texture and rough surface is easy to generate pain and even hurt the skin when being directly contacted with the skin, and after the active carbon is coated by adopting the porous zein/polylactic acid, the polymer composite coating layer can endow the cleaning massage particles with smooth and softer surface, and can avoid the direct contact of the active carbon and the skin; in addition, in the composite coating layer, the zein and the polylactic acid both have higher hydrophobicity, so that the zein and the polylactic acid have an adsorption effect on oil stains, and the porous structure of the coating layer can ensure that the zein and the polylactic acid do not excessively influence the adsorption function of the activated carbon.
Example 4 the partial cleaning massage particles of example 3 were replaced with equal quality wood particles, and the test results of comparative example 3 and example 4 show that: compared with the single cleaning massage particles, the combination of the cleaning massage particles and the wood particles can reduce the pain although the oil removal effect is influenced to a certain extent. The reason is that: the active carbon of the core layer of the cleaning massage particles is not easy to deform, can keep better oil removal effect, but can also cause higher hardness of the cleaning massage particles; the texture of the wood particles is soft, so that the wood particles are more comfortable when being smeared on the skin, but the soft texture can also cause the pores to be easily deformed and reduced in the using process, so that the wood particles are not beneficial to the absorption of oil stains.
The test results of comparative example 1 and comparative example 2 show that: the cleaning massage particles treated by vacuum microwave can improve the deoiling effect of the shower gel. The reason is that: in the vacuum microwave treatment process, under the action of the air pressure difference between the inside and the outside of the particles and microwaves, air in the activated carbon vibrates and escapes, and pores are formed in the zein/polylactic acid coating layer, so that the excessive influence of the coating layer on the oil absorption effect of the activated carbon is prevented.
Comparing the test results of example 1 and comparative example 3, and example 2 and comparative example 5, it can be seen that: the coating layer outside the active carbon does not contain polylactic acid or the content of the polylactic acid is too low, so that the deoiling effect of the shower gel is not ideal. The reason is that: the polylactic acid has higher air permeability, and molecular chains of the polylactic acid form a net structure through physical entanglement, and are easily influenced by escaping air during vacuum microwave treatment to form larger pores, so that the influence of the coating layer on the oil absorption effect of the activated carbon can be reduced, and the cleaning massage particles have better oil removal function.
Comparing the test results of example 1 and comparative example 4, and example 3 and comparative example 6, it can be seen that: the coating layer outside the active carbon does not contain zein or the content of the zein is too low, so that the comfort degree of the shower gel during smearing is not ideal. The reason is that: the zein molecular chains are crosslinked through hydrogen bonds and disulfide bonds, so that a zein/polylactic acid crosslinking network has certain mechanical strength, and a coating layer is prevented from being damaged in the preparation and use processes of the shower gel.
Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that the embodiments may be modified or changed without departing from the spirit of the present invention within the scope of the appended claims.
