Description
Technical Field
The application relates to the field of talcum powder, in particular to pearl talcum powder and a preparation method thereof.
Background
The talcum powder is a care product after bathing, and can absorb moisture and heat on the skin, so that people after bathing feel dry and cool. Meanwhile, the talcum powder also has the health-care effect and can improve some functions of the human body.
The prior common talcum powder mainly comprises talcum powder; however, the talc powder inevitably contains lead, and long-term use of the talc powder may adversely affect the human body and even induce cancer. The pearl powder is rich in various amino acids and nutrient components, has good affinity with human body, and has the effect of making people dry and cool; the compendium of materia Medica is loaded: the pearl is salty, sweet, cold and nontoxic. Relieving palpitation and nodulation. The coating is smooth and has good color. Applied to hands and feet, without skin retrogradation. Therefore, pearl toilet powder prepared by replacing talcum powder with pearl powder is more and more concerned.
Along with the development of society and the improvement of living standard of people, the sensory requirement on the pearl talcum powder is higher and higher. At present, indexes for evaluating sensory properties of pearl toilet powder mainly comprise: 1. dispersibility: the pearl toilet powder is required to be uniformly dispersed and less agglomerated; 2. skin feel: the powder is required to be fine and smooth, and the skin has cool and dry feeling after the use; 3. dust emission property: the pearl toilet powder is required to raise less dust when in use.
Disclosure of Invention
In order to improve the sensory property of the pearl toilet powder, the application provides the pearl toilet powder and a preparation method thereof.
The first aspect provides pearl talcum powder, which adopts the following technical scheme:
the pearl talcum powder is prepared from the following raw materials in parts by mass: 100 parts of pearl powder, 25-50 parts of phase-change material microcapsule powder and 1-5 parts of plant extract; the phase change temperature of the phase change material is 28-37 ℃.
By adopting the technical scheme, because the body surface temperature of a bathed human body is generally higher, after the pearl powder containing the phase-change material microcapsule powder is applied to the skin of the human body, the phase-change material is subjected to phase change and absorbs heat due to the higher body surface temperature; therefore, the phase-change material can absorb redundant heat on the body surface of a human body, so that the body surface temperature of the human body is reduced, people can feel cool and cool, and further the skin feeling of the pearl talcum powder is favorably improved, and the sensory property of the pearl talcum powder is improved. Meanwhile, the microcapsule is adopted to encapsulate the phase change material, so that the loss of the phase change material in use can be effectively reduced.
The phase change temperature of the phase change material is controlled to be more than 28 ℃, so that the problem that the phase change material cannot absorb the body surface heat of a human body because the phase change material is subjected to phase change in advance before being applied to the human body is solved; meanwhile, the phase-change temperature of the phase-change material is controlled below 37 ℃, so that the problem that the phase-change material cannot play a role due to insufficient body surface temperature is solved.
In a specific possible embodiment, the phase change material is a paraffin wax with 20 carbon atoms.
Through adopting above-mentioned technical scheme, paraffin phase transition enthalpy is high, and the phase transition temperature of the paraffin that the carbon atom is 20 is about 36.7 ℃, both is less than the body surface temperature after the human body bathes, can cool down human skin after bathing effectively, is higher than conventional indoor temperature again, is favorable to reducing the problem of phase transition in advance.
In a specific embodiment, the phase change material microcapsule powder is prepared by the following method:

Referring to Table 3, it can be found from the test results of examples 1 to 5 and comparative examples 1 to 3 that: with the addition of the phase-change material microcapsule powder into the raw materials of the pearl toilet powder, the skin feel score is obviously improved. The applicant believes this is due to: after the talcum powder is applied to the skin of a human body, the temperature of the skin of the human body after bathing is generally higher than the phase change temperature of the phase change material microcapsule powder, so that the phase change material (paraffin) generates a solid-liquid phase change reaction and absorbs redundant heat on the surface of the human body, a user feels cool, and the skin feeling is improved. However, when the phase-change material microcapsule powder is excessively used, the proportion of pearl powder in the talcum powder is reduced, so that the effect of the pearl powder is reduced, and the integral skin feeling of the talcum powder is reduced.
From the results of the tests of example 1, example 6 and comparative examples 4 to 5, it can be found that: when the phase-change temperature of the phase-change material is lower (comparison example 4, the phase-change temperature is 24 ℃), the phase-change material is likely to have phase change before being applied to a human body, the phase-change material microcapsule powder cannot play the due role, and the skin feel score of the obtained pearl talcum powder is not high. Meanwhile, when the phase-change temperature of the phase-change material is higher (comparison example 5, the phase-change temperature is 43 ℃), the body surface temperature of people after bathing is not enough to enable the phase-change material to effectively generate phase change, so that the redundant heat of the body surface of a human body cannot be effectively absorbed, and the skin feeling of the obtained pearl talcum powder is not high. The pearl talcum powder with ideal performance can be obtained by adopting the paraffin with 20 carbon atoms (example 1, the phase transition temperature is 36.7 ℃) and the paraffin with 18 carbon atoms (example 6, the phase transition temperature is 28 ℃) as phase-change materials; however, since the phase transition point of the paraffin having 18 carbon atoms is about 28 ℃, the pearl toilet powder prepared from the paraffin having 18 carbon atoms should be stored under a more severe condition, and the pearl toilet powder should be stored in the shade.
From the results of the tests of example 7 and examples 9 to 12, it was found that: the 2-octenyl succinic anhydride modified fenugreek gum powder is added into the raw materials, which is beneficial to improving the skin feel score of the pearl toilet powder. The applicant believes this is due to: the tonka bean gum powder has good moisture absorption capacity, and can absorb excessive moisture and humidity on the body surface of a human body after bathing, so that the human body feels dry and comfortable, and the skin feeling is improved.
From the results of the tests of example 11 and examples 13 to 15, it was found that: with the addition of corn starch, the skin feel score of the pearl toilet powder is increased. This is because: the corn starch also has good moisture absorption capacity, and can improve the dry feeling of the skin when being applied to a human body.
The results of the tests of comparative example 14 and examples 16 to 17 were as follows: the skin feel score of the pearl talcum powder obtained by matching the tonka-bean gelatine powder and the corn starch is obviously higher than that of the talcum powder obtained by singly using the tonka-bean gelatine powder or the corn starch. The possible reasons are: the tonka bean gum powder has high hygroscopicity, the corn starch also has good hygroscopicity and fine hand feeling, and the cooperation of the tonka bean gum powder and the corn starch can generate synergistic effect, so that the skin feeling score of the obtained pearl talcum powder is obviously improved, namely the sensory property of the pearl talcum powder is improved. Meanwhile, the color and the smell of the pearl talcum powder brought by the tonka-bean glue powder are reduced by matching the tonka-bean glue powder and the corn starch.
The results of the tests of comparative example 14 and example 18 were obtained: the 2-octenyl succinic anhydride is adopted to modify the tonka-bean gum powder, which is beneficial to improving the dispersibility of the pearl talcum powder. The possible reasons are: the 2-octenyl succinic anhydride can improve the dispersibility of the tonka-bean gum powder, so that the tonka-bean gum powder is not easy to agglomerate and is dispersed more uniformly, and the dispersibility of the pearl talcum powder is improved.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
