Embodiment 1

[0042] A method for preparing lipstick physically modified by porous starch, the steps of which are:

[0043] Porous starch (2.3%), silicon dioxide (0.4%) and glycerin (0.3%) are mixed into a composite powder (accounting for 3% of the total). Titanium dioxide 2.0%, red 204 No. 0.6%, sour orange No. 203 1.0%, candelilla wax 9.0%, refined ozokerite wax 15.0%, carnauba wax 5.%, lanolin 11.0%, liquid paraffin 18.0%, nutmeg Acid 25.2%, isopropyl myristate 10.0%, appropriate amount of spices and antioxidants, mix according to the above proportions, heat and stir at 65-70°C until a uniform agitated body is obtained, and pour the obtained lipstick initial product into the mold, Compress, unmold, cool, and finally pack the finished lipstick.

Embodiment 2

[0045] A method for preparing cheek red physically modified by porous starch, the steps are:

[0046] (1) Mix 8.5% of porous starch, 1.0% of titanium oxide and 0.5% of preservative in proportion, sieving, and mixing;

[0047] (2) Mix 8.5% of porous starch, 1.0% of iron oxide, and 0.5% of spices in proportion, sieving, and mixing;

[0048] (3) Mix 3.0% porous starch, 1.0% saturated fatty acid glycerides, and 1.0% propylene glycol in proportions, sieving, and mixing;

[0049] (4) Mix the three composite powders of steps (1)-(3) with 25.0% intermediate non-freezing rock, 20.2% selenium dioxide, 20.0% kaolin, 5.0% zinc oxide, and 5.0% zinc stearate to obtain Finished cheek red.

Embodiment 3

[0051] A method for preparing powder that is physically modified by porous starch, the steps are:

[0052] (1) Mix 46.2% of porous starch, 6.3% of silicon dioxide, and 0.5% of bactericide according to the ratio, sieving and mixing;

[0053] (2) Mix 31.4% of porous starch, 3.8% of saturated fatty acid, 3.8% of saturated fatty acid glyceride, and 1.0% of perfume in proportion;

[0054] (3) Combine the two composite powders of steps (1)-(2) with 3.0% zinc oxide and 4.0% magnesium stearate.

[0055] The finished product is obtained by mixing.

Abstract

The invention discloses application of porous starch in physical modification of cosmetics. Porous starch accounting for 1-50% of weight of raw materials is added to serve as an adsorbent to adsorb related sensitizers in cosmetics like lipstick, cheek stick, face powder, whitening powder, white lead powder, eyelid pigment and sunscreen cream to enable the sensitizers to be released slowly so as to lower irritation of the cosmetics. The porous starch can effectively lower direct irritation of the sensitizers to skin and is efficient in preparation, simple in operation, safe, low in cost and easy for industrial production.

Description

Technical field: [0001] The invention belongs to the technical field of cosmetics, and particularly relates to the application of porous starch in physical modification of cosmetics. Background technique: [0002] With the widespread use of cosmetics, there are now a dazzling array of cosmetic brands on the market, which brings about uneven product quality, which leads to more and more consumer allergies to cosmetics. As we all know, cosmetics contain many chemical substances, such as fragrances, pigments, alcohol, surfactants, preservatives, emulsifiers, and even certain Chinese herbal medicines, which may directly stimulate skin cells and cause allergies. [0003] The information disclosed in the background section is only intended to increase the understanding of the general background of the present invention, and should not be regarded as an acknowledgement or any form of suggestion that the information constitutes the prior art already known to those of ordinary skill in the ...
