Description

Film forming agent and application of petals protected by film forming agent in cosmetics

Technical Field

The invention relates to the field of cosmetics, in particular to a film-forming agent and application of petals protected by the film-forming agent in cosmetics.

Background

Petals of various kinds in nature are deeply favored by female consumers due to their beautiful appearance and pleasant fragrance. Meanwhile, the petals are rich in various nutritional ingredients, so that the petals are widely applied to the fields of health care products, foods, cosmetics and the like.

In the field of cosmetics, the petals can bring nice visual enjoyment to consumers, so that the consumers can relax the mood and achieve the aim of joyful mood; meanwhile, nutrient substances rich in the petals can help people to improve the skin condition. However, the application of petals also presents many challenges: firstly, natural petals are not easy to store, are easy to break and cannot show good shapes; secondly, because of rich nutrient substances and moisture, a large amount of preservative needs to be added in advance, otherwise, the natural petals are easy to rot and deteriorate, and the use value is lost; thirdly, in order to remove impurities, the nutrient contents of the petals can be lost and the color of the petals can be faded by adopting methods such as high-temperature cleaning, solvent cleaning and the like. In addition, problems such as petal brilliance and color deposition lead to a decrease in consumer desire to purchase petal cosmetics.

Disclosure of Invention

The invention aims to overcome the problems and provide a film-forming agent, which is applied to petal protection and can well solve the problems of petal frangibility, preservative addition, nutrient loss, fading and the like.

The technical scheme of the invention is as follows:

a film forming agent comprises the following components in percentage by mass: 3-10% of beeswax, 5-35% of hydrogenated (styrene/methyl styrene/indene) copolymer, 1-30% of polymethylsilsesquioxane and 25-91% of solvent.

The beeswax is renewable beeswax of natural source. The beeswax is obtained by centrifuging honeycomb to remove honey, and has pure natural and sustainable characteristics as a byproduct of honey. The cosmetic beeswax has melting point of 61-66 deg.c, high transparency, plasticity and high viscosity. It plays an important role in the adsorption of the film-forming agent on the surfaces of the petals.

The hydrogenated (styrene/methylstyrene/indene) copolymer: the material is prepared by a series of hydrogenation reactions of aliphatic resin and aromatic resin. It can be dissolved in proper proportion with proper oil to form colorless and tasteless transparent film. The film has high refractive index, good stability and excellent oxidation resistance. Suitable hydrogenated (styrene/methylstyrene/indene) copolymers may include Regalite^TMR1100 CG (from Eastman Chemical Company, USA).

The polymethylsilsesquioxane is a solid solvent-free MT type organic silicon resin with the softening temperature of only 50 ℃. Because the melting point is low, a transparent uniform phase can be formed in the solvent, the transparent uniform phase is applied to the surface of an object, and after the solvent is volatilized, a layer of soft film can be formed and perfectly attached to the surface of an irregular substance. It plays an important role in the toughness of the film-forming agent and the uniformity of the film. Suitable polymethylsilsesquioxanes may comprise BELSIL PMS MK POWDER (from Waters, USA).

The solvent can be one or a mixture of more of caprylic/capric triglyceride, isopropyl myristate and ethylhexyl palmitate.

The embodiment of the invention provides a preparation method of the film forming agent, which comprises the following steps:

step X1, adding the hydrogenated (styrene/methylstyrene/indene) copolymer to a beaker;

step X2, adding a solvent into a beaker, heating the beaker to 110 ℃ under the stirring condition, and cooling to 70-80 ℃ after the hydrogenated (styrene/methyl styrene/indene) copolymer is dissolved and transparent;

step X3, adding beeswax into a beaker, and stirring to dissolve the beeswax and make the beeswax transparent;

and step X4, adding the polymethylsilsesquioxane into a beaker, stirring to dissolve the polymethylsilsesquioxane to be transparent, and cooling to room temperature for later use.

The embodiment of the invention also provides a method for protecting the color and the shape of petals by applying the film-forming agent, which comprises the following steps:

s1, selecting artificially picked fresh petals and placing the petals in a special flower cage;

step S2, adding proper deionized water into an ultrasonic cleaning machine (40 KHZ), putting the flower cage filled with petals in the step S1 into the ultrasonic cleaning machine together, and cleaning for 3-10 minutes; determining that impurities on the surfaces of the petals are cleaned;

s3, flatly spreading the petals in the S2 into a drying oven with air blowing, starting drying, drying for 3-10 hours at 30-50 ℃, and closing drying equipment when the water content of the petals reaches 5-15%;

and step S4, putting the petals in the S3 into an ozone chamber, and standing the petals in the ozone chamber for 1-1.5 hours. Then filling into a sterile bag;

s5, putting the petals in the S4 into the film forming agent (66-75 ℃), fishing out and shaking to enable the redundant film forming agent to fall off;

s6, standing the petals prepared in the S5 for 1 minute, and then putting the petals into a roller to roll for 3-5 minutes;

and step S7, putting the petals prepared in the step S6 into a sterile bag for later use.

Compared with the prior art, the film-forming agent has the following characteristics after wrapping the petals:

firstly, the formed film has high transparency and cannot influence the appearance of petals;

secondly, the method has small damage to the petals and good integrity of the petals;

thirdly, the original color of the petals is changed slightly, so that the original color state can be kept for a long time;

fourthly, the film on the surface of the petal has good hydrophobicity and inertia, and can be preserved for a long time in cosmetics such as water aqua, shower gel, shampoo and the like;

nutrient substances in the petals can be well sealed and stored in the capsule formed by the film forming agent, and the nutrient substances of the petals can be released when the petals are kneaded;

the petals treated by the film-forming agent in the patent can only be used in transparent cosmetics such as water aqua, shower gel, shampoo and the like, and are not suitable for non-transparent products, pure oil products and water-in-oil system products.
