Technical field
The present invention relates to the preparation method of a kind of facial-care oil-Absorbing Sheets.
Background technology
In beauty and skin care, oil-Absorbing Sheets or oil suction film are a kind of important facial-care aids, are mainly used in absorption
And remove the oily matter of human facial skin's secretion.There is shortcomings in current oil-Absorbing Sheets or oil suction film.As: opaque class is inhaled
Oilpaper opaque during preserving and using can come off；Delicate skin may be injured when natural fiber class oil-Absorbing Sheets use；Change
Property fiber-like oil-Absorbing Sheets there may be the residual of chemical raw material, in use transfers to site of action, causes allergy.Cause
This, need a kind of oil absorption more effective, the oil-Absorbing Sheets having no stimulation skin.
Summary of the invention
It is more preferable that the present invention has designed and developed a kind of oil absorption, and the oil-Absorbing Sheets having no stimulation.
The present invention provides techniques below scheme:
A kind of preparation method of facial-care oil-Absorbing Sheets, including:
Polylactic acid and poly-3-hydroxybutyrate alkyl caproate are dissolved in organic solvent by step (1), prepare polylactic acid and gather

Step (2) is by ammonium bicarbonate solubility in water, and the aqueous phase prepared, in aqueous phase, the concentration of ammonium hydrogen carbonate is 4.3
～6.7g/L；
Organic facies is divided into 4～7 parts by step (3), is added portionwise into aqueous phase, carries out even after often adding a organic facies
Slurry processes, and the time of each homogenized is 12～25min, and the rotating speed of homogenized gradually increases, homogenized for the first time
Rotating speed be 300 turns/min, every time the rotating speed of homogenized all increases by 100～130 than the rotating speed of last homogenized afterwards
Turning/min, obtain emulsion, total consumption of organic facies and the volume ratio of aqueous phase are 6～8:1；
Emulsion is placed under room temperature 1～2h by step (4)；
Step (5) be placed in-10～-15 DEG C at lyophilization 3～4h.
Preferably, in the preparation method of described facial-care oil-Absorbing Sheets, in described step (3), at each homogenate
The time of reason is 20min.
Preferably, in the preparation method of described facial-care oil-Absorbing Sheets, in described step (3), organic facies total
Consumption is 6.9:1 with the volume ratio of aqueous phase.
Preferably, in the preparation method of described facial-care oil-Absorbing Sheets, in described step (4), emulsion is put
2h under room temperature.
Preferably, in the preparation method of described facial-care oil-Absorbing Sheets, in described step (5), it is placed at-12 DEG C
Lyophilization 3.5h.
The preparation-obtained oil-Absorbing Sheets of preparation method of facial-care oil-Absorbing Sheets of the present invention have good suction
Oil ability.
Detailed description of the invention
The present invention is described in further detail below, with make those skilled in the art with reference to description word can evidence
To implement.
The present invention provides the preparation method of a kind of facial-care oil-Absorbing Sheets, including:
Polylactic acid and poly-3-hydroxybutyrate alkyl caproate are dissolved in organic solvent by step (1), prepare polylactic acid and gather
The organic facies of 3-hydroxybutyrate alkyl caproate mixed liquor；
Step (2) is by ammonium bicarbonate solubility in water, and the aqueous phase prepared, in aqueous phase, the concentration of ammonium hydrogen carbonate is 4.3
～6.7g/L；
Organic facies is divided into 4～7 parts by step (3), is added portionwise into aqueous phase, carries out even after often adding a organic facies
Slurry processes, and the time of each homogenized is 12～25min, and the rotating speed of homogenized gradually increases, homogenized for the first time
Rotating speed be 300 turns/min, every time the rotating speed of homogenized all increases by 100～130 than the rotating speed of last homogenized afterwards
Turning/min, obtain emulsion, total consumption of organic facies and the volume ratio of aqueous phase are 6～8:1；
Emulsion is placed under room temperature 1～2h by step (4)；
Step (5) be placed in-10～-15 DEG C at lyophilization 3～4h.
The present invention is by adding organic facies by several times, and the time of each homogenized is 12～25min, organic to promote
Mutually and aqueous phase can be the most highly uniform mixing.The oil-Absorbing Sheets that the present invention prepares are highly uniform in microstructure, micropore
Even aperture distribution is consistent, so that oil-Absorbing Sheets have homogeneous oil absorption.After tested, the average pore size of micropore 3.1～
3.6μm.Oil-Absorbing Sheets can absorb and be equivalent to 8～9 times of own wt.
Organic facies gradually adds to aqueous phase, i.e. organic facies gets more and more, in order to obtain uniform dispersion effect, and finally
Obtain suitable microcellular structure, the careful design rotating speed of each homogenized, the especially rotating speed of homogenized in the present invention
Gradually to increase with certain amplitude.
