Disclosure of Invention
In order to solve the technical problems, the invention provides a mild low-irritation cleansing massage type facial cleanser and a preparation method thereof. The cleansing cream has the advantages that the cleansing particles with special structures are compounded with the wood particles, so that the cleansing cream has better oil removal, cutin removal and massage effects, and has less irritation to skin.
The specific technical scheme of the invention is as follows:
the mild and low-irritation cleaning massage type facial cleanser comprises the following components in parts by weight: 10-15 parts of sodium lauroyl glutamate, 5-10 parts of sodium myristoyl glutamate, 1-3 parts of cleaning particles, 0.5-1.5 parts of wood particles, 0-5 parts of natural plant extract, 0.5-1 part of glycerol stearate, 20-35 parts of water, 15-20 parts of glycerol and 0-0.4 part of essence; the cleaning particles comprise a porous calcium carbonate core layer and a porous zein/polylactic acid composite wall layer coated outside the porous calcium carbonate core layer.
According to the invention, the cleaning particles with special structures are compounded with the wood particles, so that the oil removal and cutin removal effects of the facial cleanser can be improved, and the facial cleanser has small stimulation to skin. Specifically, the method comprises the following steps:
in the cleaning particles, the porous calcium carbonate core layer can play a role in deoiling by utilizing higher porosity, and the cleaning particles can play roles in massaging and removing cutin in the kneading process of the face cleaning cream. However, the porous calcium carbonate with hard texture and rough surface is easy to cause skin damage when being directly contacted with the skin, therefore, the porous calcium carbonate is coated by adopting the porous zein/polylactic acid, and the polymer composite wall layer can endow the cleaning particles with smooth and softer surfaces and can avoid the direct contact of the porous calcium carbonate and the skin; in addition, in the composite wall 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 wall layer can ensure that the zein and the polylactic acid do not excessively influence the adsorption function of the porous calcium carbonate.
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 porous calcium carbonate in the core layer of the cleaning particles is not easy to deform, can keep a good oil removal effect, but can also cause high hardness of the cleaning particles and relatively large stimulation to skin. Therefore, the cleansing cream combines the wood particles and the cleansing particles, and has stronger cleansing power and lower irritation.
Preferably, the particle size of the cleaning particles is 40-60 μm, wherein the diameter of the porous calcium carbonate core layer is 25-35 μm.
Preferably, the preparation method of the cleaning particle is as follows:
(1.1) uniformly mixing calcium chloride, sodium polystyrene sulfonate and water to prepare a calcium chloride solution; uniformly mixing sodium bicarbonate, sodium polystyrene sulfonate and water to prepare a sodium bicarbonate solution; dropwise adding a calcium chloride solution into a sodium bicarbonate solution, standing at 30-40 ℃ for reaction for 1-1.5h, centrifugally separating out a product, washing, drying and sieving to obtain porous calcium carbonate;
(1.2) dissolving zein and polylactic acid in acetone to prepare a coating agent solution; and uniformly spraying the coating agent solution on the surface of the porous calcium carbonate, performing vacuum ultrasonic treatment, and then performing heat treatment to remove acetone to obtain the cleaning particles.
In the step (1.1), sodium polystyrene sulfonate is used as a template agent, calcium chloride reacts with sodium bicarbonate to generate porous calcium carbonate, and the porous structure of the porous calcium carbonate can adsorb oil stains and endow the cleansing cream with a better oil removal effect.
In the step (1.2), after the coating agent is sprayed, the particles are subjected to vacuum ultrasonic treatment, and air in the porous calcium carbonate escapes through vibration under the action of the air pressure difference between the inside and the outside and the ultrasonic action, so that pores are formed in a zein/polylactic acid wall layer, and the wall layer is prevented from excessively influencing the adsorption action of the porous calcium carbonate.
The invention adopts zein and polylactic acid to carry out composite coating on porous calcium carbonate, and has the following effects: 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 ultrasonic treatment to form larger pores; the zein molecular chains are crosslinked through hydrogen bonds and disulfide bonds, so that a zein/polylactic acid crosslinked network can have certain mechanical strength, and the wall layer is prevented from being damaged in the preparation and use processes of the facial cleanser. Therefore, the polylactic acid and the zein are adopted for composite coating, so that larger pores can be formed in the wall layer during vacuum ultrasonic treatment, and the wall layer has higher mechanical strength, thereby endowing the cleaning particles with better deoiling function and effectively preventing the cleaning particles from damaging the skin.

The cleansing creams of examples 1-3 and comparative examples 1-8 were tested on 25 subjects aged 20-40 years, the test items and methods were as follows:
(1) the oil removal effect is as follows: after the face is cleaned by using the cleansing cream (5 g each time, and cleaned by using clear water at 25 +/-2 ℃), the skin oil content of the face of a subject is tested (a point is taken on the forehead, the chin and the cheeks at two sides respectively, the average value is taken), the skin oil content reduction rate of each subject before and after cleaning is calculated, the average value is taken for each group, and the result is shown in table 1;
(2) exfoliating effect: before use, the inner forearm of each subject was tested for skin roughness; after the inner side of the forearm was washed with the cleansing cream for 30 days (the use frequency was once every 5 days, 1-2g each time), the roughness of the inner side of the forearm of each subject was measured again, the reduction rate of the roughness of the skin was calculated, and the average value was taken for each group, and the results are shown in table 1;
(3) sensory evaluation: 0.5-1.0g of the cleansing cream is taken, the cheek of a subject is massaged for 2min, the skin pain condition is scored, 0 score represents no pain, 10 score represents obvious pain, and the results are shown in table 1 by averaging each group.
TABLE 1
The test results of comparative example 2 and comparative examples 1 and 2 show that: when single cleaning particles are adopted, the oil removal and cutin removal effects are good, but the skin irritation is large; while the use of a single wood particle is less irritating to the skin, the oil removal and exfoliation effects are relatively poor. The reason is that: 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 porous calcium carbonate in the core layer of the cleaning particles is not easy to deform, can keep a good oil removal effect, but can also cause high hardness of the cleaning particles and relatively large stimulation to skin.
The test results of comparative example 2 and comparative example 3 show that: after the zein/polylactic acid composite wall layer is coated on the surface of the porous calcium carbonate, the stimulation to the skin is obviously weakened, and the deoiling effect is not obviously reduced. The reason is that: the porous calcium carbonate with hard texture and rough surface is easy to generate pain and even damage the skin when being directly contacted with the skin, and after the porous calcium carbonate is coated by adopting the porous zein/polylactic acid, the polymer composite wall layer can endow the cleaning particles with smooth and softer surface, so that the porous calcium carbonate can be prevented from being directly contacted with the skin; in addition, in the composite wall 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 wall layer can ensure that the zein and the polylactic acid do not excessively influence the adsorption function of the porous calcium carbonate.
The test results of comparative example 2 and comparative example 4 show that: the cleaning particles subjected to vacuum ultrasonic treatment can improve the oil removal effect of the facial cleanser. The reason is that: in the vacuum ultrasonic treatment process, air in the porous calcium carbonate escapes in a vibrating manner under the action of air pressure difference between the inside and the outside of particles and ultrasonic action, and pores are formed in a zein/polylactic acid wall layer, so that the oil removal effect of the porous calcium carbonate is prevented from being excessively influenced by the wall layer.
Comparing example 2 with comparative example 5, and example 1 with comparative example 7, it can be seen that: the wall layer of the cleaning particles does not contain polylactic acid or the content of the polylactic acid is too low, so that the oil removal effect of the cleansing cream 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, so that the polylactic acid is easily influenced by escaping air during vacuum ultrasonic treatment to form larger pores, thereby reducing the influence of the wall layer on the adsorption effect of the porous calcium carbonate and endowing the cleaning particles with better deoiling function.
Comparing the test results of example 2 with comparative example 6, and example 3 with comparative example 8, it can be seen that: the wall layers of the cleaning particles do not contain zein or contain too low a content of zein, which causes the irritation of the cleansing cream to be large. The reason is that: the zein molecular chains are crosslinked through hydrogen bonds and disulfide bonds, so that a zein/polylactic acid crosslinked network can have certain mechanical strength, and the wall layer is prevented from being damaged in the preparation and use processes of the facial cleanser.
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.
