Abstract
The invention discloses a kind of sustained release mosquito-repellent essential oil microcapsules children's talcum powders and preparation method thereof, which is mainly made of porous-starch microcapsules and auxiliary element.Microcapsules of the present invention solve mosquito-repellent essential oil and are directly added into volatile, disadvantage that stability is poor after formula, extend the mosquito repellent timeliness of talcum powder.In addition, microcapsules of the present invention are plant component, moisture absorption is good, and instead of the unsafe ingredient of talcum powder class in common talcum powder, each ingredient is pure natural, and product is non-stimulated, safe, is suitable for children, including infant.
Description
Technical field
The present invention relates to daily chemical product fields, concretely relate to a kind of sustained release mosquito-repellent essential oil microcapsules children's talcum powder
And preparation method thereof.
Background technique
2 months in 2016, Missouri, USA court decision Johson & Johnson pay an indemnity 7200 dollars, because its sale contains talcum powder
Children's talcum powder.Talcum powder is the main component of current children's talcum powder, contains inseparable lead.Lead enters in infants
It is difficult to exclude, long-term accumulation can seriously affect the intelligence and body development of baby.And the asbestos impurity in talcum powder, have compared with
High carcinogenesis.The general particle of talcum powder is small, easily enters vagina, uterine neck etc., and be attached to the surface of ovary, stimulates ovary
Epithelial hyperplasia, and then induce oophoroma.Therefore, girl baby should not flutter the talcum powder of the meal component containing talcum in lower body part.
Granted patent CN201110269289 discloses a kind of microporous starch talcum powder, which uses micropore starch conduct
Hygroscopic agent replaces talcum powder, increases the safety of product.But the plant extracts of auxiliary element relative to plants essential oil at
For point, purity is not high, effect is not significant.The technical matters requires simple, microporous starch talcum powder not have mosquito repellent function.
Summer children are vivaciously active, metabolism is vigorous, and other than long prickly heat of perspiring, body can also secrete more " front three
Amine " is easy to cause mosquito.Bite by mosquitos can reduce the sleep quality of baby, influence their healthy growth.New type of safe at present
Mosquito repellent product use plants essential oil as mosquito repellent function ingredient more, the smell expelling mosquito for utilizing its fragrance special.Although planting
Object essential oil is safe and non-stimulating, and repelling effect is good, but it there is also unstable, the fast problems of volatilization.In order to reduce derived essential oil
It volatilizees and fails in product processing, the present invention wraps up mosquito-repellent essential oil using porous-starch, prepares a kind of novel porous starch
Microcapsules.The microcapsules have sustained release essential oil effect, and children is allowed to have the exquisite sleep of a long-acting mosquito repellent.
Summary of the invention
Aiming at the problem that existing talcum powder contains easy carcinogenic substance talcum powder and child susceptible bite by mosquitos, the present invention provides
A kind of sustained release mosquito-repellent essential oil microcapsules children's talcum powder and preparation method thereof, the talcum powder is pure natural harmless, and has mosquito repellent effect
Fruit.
The invention is realized by the following technical scheme.
A kind of sustained release mosquito-repellent essential oil microcapsules children's talcum powder, the talcum powder are contained by following components by following quality percentage
Amount mixes: porous-starch microcapsules 77.0-85.0%, low molecular chitosan 4.0-10.0%, pollen pini 8.0-15.0%.
A kind of above-described preparation method for being sustained mosquito-repellent essential oil microcapsules children's talcum powder, comprising the following steps:
(1) porous-starch, low molecular chitosan and pollen pini are crushed respectively in pulverizer, is sieved；
(2) mosquito-repellent essential oil is added dropwise on porous-starch, is uniformly mixed under room temperature, keep the temperature 1-2d at 30-55 DEG C
Porous-starch microcapsules are made；
(3) porous-starch microcapsules, low molecular chitosan and pollen pini are weighed, is added to the mixer uniformly mixed, is obtained
Talcum powder；
(4) talcum powder is subjected to ultraviolet disinfection, controls 35-40 DEG C of temperature, sterilization time 0.5-2h.
Preferably, step (1) porous-starch be Corn Porous Starch, porous starch from sweet potato, porous tapioca and
One of porous wheaten starch is a variety of.
Preferably, step (1) sieving was 200-7000 mesh.
Preferably, step (2) mosquito-repellent essential oil is lemon grass (Cymbopogon citratus) essential oil, oil of Cymbopogon winterianus, shaddock peel essential oil and Peppermint essential oil
One of or it is a variety of.
Preferably, the mass ratio of step (2) mosquito-repellent essential oil and porous-starch is 1:170-1:155.
Preferably, step (2) the mosquito-repellent essential oil additional amount is 0.1-1mL.
Preferably, the temperature of step (2) described heat preservation is 45 DEG C.
Preferably, step (3) the porous-starch microcapsules account for the 77.0-85.0% of talcum powder quality；Low molecule shell is poly-
Sugar accounts for the 4.0-10.0% of talcum powder quality；Pollen pini accounts for the 8.0-15.0% of talcum powder quality.
Porous-starch microcapsules prepared by the present invention have large pore spherical structure, can be used for wrapping up essential oil, play protection and
Slow releasing function.Microcapsules guarantee the safety that children use from natural extract, nontoxic.And suction with higher
It is moist, child skin can be absorbed and secrete extra sweat and grease, guarantee that skin comfort is dry and comfortable.
Low molecular chitosan is natural bacteriostatic active ingredients, to Escherichia coli, staphylococcus aureus, hay bacillus,
Bacillus perfringens has strong inhibiting effect, ensure that the anti-corrosion effect in cosmetics for children formula.Pollen pini can be effective
Childhood eczema and red hip are solved the problems, such as, for a kind of natural harmless effect ingredient.Mosquito-repellent essential oil is volatile, unique aroma
Taste can be with expelling mosquito.
Compared with prior art, the present invention has the advantage that and beneficial effect:
1, for children's talcum powder at present on the market, largely addition talcum powder causes baby especially as primary raw material
It is girl baby's safety problem carcinogenic because of sucking dust, the present invention replaces talcum powder with porous-starch microcapsules, and granular size is moderate,
Reduce the phenomenon that powder enters abdominal cavity, induce ovary carcinogenesis by vagina.
2, using micro-capsule package technology, mosquito-repellent essential oil is encapsulated in porous-starch shell, product has both been effectively prevented and has added
The problem of work process causes essential oil to volatilize because dealing with improperly, and mosquito repellent effect reduces；It is unstable that essential oil is reduced again, with other compositions
The problem of interaction.
3, mosquito-repellent essential oil microcapsules of the present invention have slowly releasing effect, do not influence again while the evaporation rate for slowing down essential oil
The mosquito repellent effect of product；Smell holding 6 hours or more of the unique salubrious fragrance of essential oil, effectively extend mosquito repellent time.
4, mosquito-repellent essential oil microcapsules talcum powder of the present invention has high hygroscopic property, controls the water and oil balance of child skin, subtracts
Few clogging of pores leads to long prickly heat, red hip problem, has absorbing sweat mosquito repellent, smooth skin effect.
5, talcum powder all the components are refined by animals and plants processing, are free of heavy metal element lead, will not be produced in human body
Raw cumulative function, and ingredient is natural, it is small to the irritation of child skin；It is fragrant, nontoxic, pair will not be caused after use
Effect.
