Description
Technical field
The present invention relates to personal-care supplies field, and in particular to a kind of zinc oxide composition of high stability and spreadability
And its preparation method and application.
Background technology
With the development of society and the improvement of people's living standards, the use of diaper is more and more in baby, due to baby
Youngster skin texture development it is not yet complete, skin barrier effect it is too weak and very tender and lovely, if fail after children's stool and urine and
When more changing babies' napkin, the urea in the long-time immersion of urine or urine decomposed by the bacterium in excrement, and caused ammonia can stimulate skin
Skin, easily cause skin problem, may seriously make excoriation even rotten to the corn, the diaper rash being commonly called as or red hip.
Zinc oxide can effectively waterproof, isolation, convergence skin, and can be effectively antibacterial, alleviate and preventing diaper dermatitis,
Therefore it is widely used in all kinds of baby's hip pad products.Existing nano level zinc oxide is usually used among sunscreen product, but because of its poison
Rationality is still disputable, and the zinc oxide that thus be accordingly used in hip pad product is mostly not surface treated micron-sized zinc oxide, is answering
Used time is more inconvenient.Usually occur the problem of layering, aggregation, precipitation, spreadability difference in formula, reduce hip pad class product
Stability, it is particularly particularly evident in high content zinc oxide formula.Because its dispersiveness and spreadability are poor, added in application
Frictional resistance, baby skin is caused secondary injury, and reduce effect of the zinc oxide in hip pad product,
To the processing step of zinc oxide in a kind of baby's diaper ointment and preparation method thereof disclosed in application number 201610537302.1
It is：Zinc oxide is added in grease and ground 3-5 times on colloid mill, crosses 180 mesh sieves；Such a method can disperse zinc oxide
Among grease, but the long-term dispersiveness effect for zinc oxide is little, occurs that zinc oxide segregation etc. is asked under high temperature
Topic.
A kind of baby's hip pad liquid talcum powder and preparation method thereof disclosed in publication number 104622774A, in the preparation method
Using hydroxy-ethyl acrylate/sodium acryloyldimethyl taurate copolymers suspension oxidation zinc, oxidation is prevented to a certain extent
The precipitation of zinc, but fail the scattering problem for effectively solving zinc oxide.
A kind of Water-In-Oil infant buttocks-care cream and preparation method thereof is disclosed in application number 201510401597.5, this method is led to
Cross specific dispersant and disperseed with the zinc oxide for comparing high content, the scattered of zinc oxide can be improved to a certain extent
Property, but improve degree and unobvious.
The content of the invention
The technical problems to be solved by the invention be overcome in the presence of prior art to micron order zinc oxide dispersiveness,
Stability, spreadability deficiency, there is provided a kind of long-time stability that can significantly improve zinc oxide, increase zinc oxide is in formula
There is composition of preferable spreadability and preparation method thereof when dispersiveness and application, improve the using effect of zinc oxide.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of zinc oxide composition of high stability and spreadability, including following weight percent composition：
Poly- hydroxy stearic acid 3%-6%；
Hydroxy stearic acid ethylhexyl 15%-30%；
Octyl dodecanol 5%-20%；
Zinc oxide 30%-60%；
Solvent complements to 100%.
Additive commonly used in the art can also be added according to actual production service condition.
Further, the weight ratio of described poly- hydroxy stearic acid and zinc oxide is 0.05-0.1：1, preferably 0.1：1.
Further, the weight ratio of described hydroxy stearic acid ethylhexyl and zinc oxide is 0.2-0.7:1, preferably
0.5：1.
Further, described solvent include caprylic/capric triglyceride, isopropyl myristate, isopropyl palmitate,
At least one of C12-C15 benzoic ethers.
A kind of preparation method of the zinc oxide composition of described high stability and spreadability, comprises the following steps：
A, poly- hydroxy stearic acid, hydroxy stearic acid ethylhexyl, octyl dodecanol, zinc oxide and solvent are mixed；
B, mixed composition is ground 1-3 times in three-roller or colloid machine；
C, the mixture after ground places 10-120min；
D, second of grinding is carried out after static placement again, is ground 1-3 times；
E, 100 mesh sieve finished products are crossed.
A kind of application of the zinc oxide composition of described high stability and spreadability, can be added with arbitrary proportion
Into Water-In-Oil commonly used in the art or oil-in-water base-material, formulation can be any one in emulsion, cream, solid-like.
After applying above-mentioned technical proposal, the present invention has the advantages that：
1st, composition of the invention can play effective peptizaiton to zinc oxide.Poly- hydroxy stearic acid is a kind of high in the present invention
The dispersant of effect, contain substantial amounts of hydroxyl on poly- hydroxy stearic acid, it is strong by intermolecular active force and zinc oxide surface
Ground combines, and forms one layer of molecular film for being covered in zinc oxide surface, reduces the aggregation tendency of zinc oxide, so as to which zinc oxide be had
Spread out to effect, reduce the aggtegation and precipitation phenomenon of zinc oxide, and cause powder more uniform and delicate, be advantageous to simultaneously
Improve the spreadability of zinc oxide.
2nd, composition of the invention can play effective stabilization, hydroxy stearic acid ethylhexyl and octyl group to zinc oxide
Dodecanol collocation uses Synergistic, can play suspension effect to a certain extent, so as to increase the stability of zinc oxide, subtract
The generation precipitated less, and the sensation of dryness during zinc oxide is smeared is improved, reduce frictional force, improve the paving of zinc oxide
Malleability.
3rd, composition is fully ground in the present invention, fully infiltration, by zinc oxide and poly- hydroxy stearic acid, hydroxy stearic acid
Ethylhexyl and octyl dodecanol fully contact, and further improve the dispersiveness of zinc oxide.
4th, the composition in the present invention, can be added to arbitrary proportion in Water-In-Oil or oil-in-water formula, long-term storage
Be not in segregation, phenomena such as precipitation.
