Embodiment Construction

[0016] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0017] The invention provides a preparation method of oil-absorbing paper for facial care, comprising:

[0018] Step (1) dissolving polylactic acid and poly 3-hydroxybutyrate caproate in an organic solvent to prepare an organic phase of a mixed solution of polylactic acid and poly 3-hydroxybutyrate caproate;

[0019] Step (2) dissolving ammonium bicarbonate in water to prepare the water phase, the concentration of ammonium bicarbonate in the water phase is 4.3~6.7g / L;

[0020] Step (3) Divide the organic phase into 4 to 7 parts, add them to the water phase one by one, perform homogenization treatment after each part of the organic phase is added, and the time for each homogenization treatment is 12 to 25 minutes, and the homogenization treatment The rotation speed increases successively. The rotation speed of the first ...

Abstract

The invention discloses a preparation method of oil-absorbing paper for facial care, comprising: step (1) preparing an organic phase of a mixed solution of polylactic acid and poly-3-hydroxybutyrate caproate; step (2) dissolving ammonium bicarbonate in In water, prepare the water phase; step (3) divide the organic phase into 4 to 7 parts, add them to the water phase one by one, and perform homogenization treatment after each part of the organic phase is added, and the time for each homogenization treatment is 12 to 25 minutes , and the rotation speed of the homogenization treatment increases successively, the rotation speed of the first homogenization treatment is 300 rpm, and the rotation speed of each subsequent homogenization treatment is increased by 100-130 rpm compared with the previous homogenization treatment, and the obtained For the emulsion, the volume ratio of the total amount of the organic phase to the water phase is 6-8:1; step (4) place the emulsion at room temperature for 1-2 hours; step (5) place it at -10--15°C to freeze Dry for 3 to 4 hours. The oil-absorbing paper prepared by the invention has good oil-absorbing capacity.

Description

technical field [0001] The invention relates to a preparation method of oil-absorbing paper for facial care. Background technique [0002] In beauty and skin care, oil-absorbing paper or oil-absorbing film is an important auxiliary tool for facial care, mainly used to absorb and remove oily substances secreted by human facial skin. There are many disadvantages in current oil-absorbing paper or oil-absorbing film. For example: powdery oil-absorbing papers will fall off during storage and use; natural fiber oil-absorbing papers may damage delicate skin when used; modified fiber oil-absorbing papers may have chemical raw material residues that are transferred to The site of action can cause allergies. Therefore, need a kind of oil-absorbing ability more effective, to the oil-absorbing paper of skin nonirritating effect. Contents of the invention [0003] The invention designs and develops an oil-absorbing paper with better oil-absorbing ability and no stimulating effect. ...
