Description
Technical Field
The invention relates to the technical field of cosmetics, in particular to a film-forming composition with a sun-screening and synergistic effect and application thereof.
Background
Low doses of uv radiation can provide skin benefits such as enhanced vitamin D synthesis, but when the skin is exposed to excessive uv radiation, it can also carry a high risk of biological damage such as sunburn, actinic keratosis, non-melanoma and even skin cancer. Sunscreen products play an important role in the prevention of photodamage to the skin.
Because the use of sunscreen cosmetics, especially high SPF products, is usually carried out outdoors in summer, the characteristics of seasons and use environments require sunscreen products to have water and sweat resistance, i.e., to maintain a certain sunscreen effect even under the condition of sweat immersion or swimming.
In the prior art, most products achieve the water and sweat resistance by adding various film forming agents, but the skin feel and the effect are not sufficiently superior, and most products neglect the migration resistance and the friction resistance of the products. When people move in places such as sandy beach, the loss of sun protection value can be caused by the friction of sand grains and the like, the loss of sun protection index can be easily caused by the actions of wiping face and sweat, and the rubbing and migration resistance performance is required when the sun protection product is smeared on the sandy beach or outdoor activities. Anti-rub and anti-migration properties are therefore also an important functional attribute of sunscreen products. Has the anti-friction performance, and can reduce the frequency of sun protection after being coated.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problem solved by the invention is how to enhance the sun protection of cosmetics, and the cosmetics are water-resistant, migration-resistant and friction-resistant.

(3) sequentially adding the phase B raw materials into a second beaker, heating to 80 ℃, and uniformly stirring and dissolving;
(4) adding the phase A raw material in the first beaker into the second beaker in a homogeneous state, and homogenizing for 5-10 min;
(5) and (3) stirring and cooling the raw materials in the completely emulsified second beaker to 60 ℃, sequentially adding the D-phase raw materials, and uniformly stirring to obtain a finished product.
To better illustrate the beneficial effects of the film-forming composition containing sunscreen boosters, a sunscreen emulsion containing sunscreen boosters was taken and subjected to the following efficacy evaluation experiments, as shown in table 2 below:
measurement of Sun Protection Factor (SPF):
SPF-290AS with solar light was measuredTMThe measuring instrument is as follows: respectively coating the sunscreen emulsion A-D samples on 5 micron frosted PMMA plates in a punctiform manner by using a pipettor, and coating the samples at a concentration of 2 mu l/cm2Is lightly and uniformly spread at 50cm2In the area of (1), with SPF-290ASTMMeasuring SPF values of the SPF values by a measuring instrument respectively, and recording the SPF values as SPF values before water resistance testing; taking the sunscreen emulsion A-D samples on 5 micron-sized PMMA plate with frosted surface by the same method, drying for 15min, soaking in water with the same strength and continuouslyTaking out after shaking for 20min, drying for 20min, soaking in water, shaking for 20min, drying with effluent, and then treating with SPF-290ASTMAnd measuring the SPF values of the water-resistant test pieces respectively by using a measuring instrument, and recording the SPF values as the SPF values after the water-resistant test. The data obtained are reported in table 3 below:
| sunscreen emulsion A | Sunscreen emulsion B | Sunscreen C | Sunscreen emulsion D | |
| SPF value before Water resistance test | 44.2 | 40.16 | 39.45 | 37.94 |
| SPF value after Water resistance test | 41.3 | 30.11 | 24.24 | 16.82 |
| Water resistance (%) | 86.26％ | 52.41％ | 27.98％ | 0％ |
Note: wherein the water repellency is the loss inhibition of the SPF values lost by water resistance testing of sunscreens a-C relative to the SPF values lost by water resistance testing of sunscreens D (without any components of the composition added).
The synergistic effect of the composition is calculated according to the formula of King:
q＝E(A+B)/[EA+EB-EA*EB]
in the formula, EA and EB have the effect when A and B are used independently; e (A + B) is the effect of the combination of the two.
Q is more than 0.85 and less than or equal to 1.15, which are added independently; q is more than 1.15 and less than or equal to 20 for reinforcement; q > 20 is a significant enhancement; q is more than 0.56 and less than or equal to 0.85 for antagonism; q is less than or equal to 0.56, and is obvious antagonism.
The water resistance of the sunscreen emulsion A is taken as a combined effect, the water resistance of the sunscreen emulsion B and the sunscreen emulsion C is respectively the effect when trimethylsiloxysilicate and the bis-hydroxypropyl polydimethylsiloxane/SMDI copolymer are used independently, the synergy coefficient q is calculated by applying a gold formula to be 1.31 and larger than 1.15, namely the composition in the sunscreen product has a synergistic effect on the water resistance.
In addition, in order of SPF value size: the sun-screening emulsion D is more than the sun-screening emulsion C is more than the sun-screening emulsion B is more than the sun-screening emulsion A, and the difference is obvious, so that the composition can also bring sun-screening synergistic effect and improve the SPF value of a sun-screening product.
(II) anti-rub, anti-migration test
And (3) testing the product: the sunscreen emulsion A and the sunscreen emulsion D; the commercial product is declared to be waterproof for 40 min.
The test method is as follows:
(1) placing 60g sunscreen emulsion A, sunscreen emulsion D, and commercial sunscreen emulsion with waterproof property for 40min in 30cm2Frosted PMMA plate at 2mg/cm2The components are weighed, evenly smeared and kept stand for 15 min.
(2) And then sucking 30g of water by a pipette to completely cover the three PMMA plates coated with the samples, and allowing the water to stay on the surface for 15 min.
(3) The surface was carefully blotted clean with a cotton ball and as little pressure as possible was applied to the surface.
(4) Three hard paper wafers of the same kind with the diameter of 6cm are respectively cut, and the surface of each hard paper wafer is flat and smooth.
(5) And (3) respectively sticking the three round pieces obtained in the step (4) to the bottom of a beaker with the weight of 500g by using double-sided adhesive tapes.
(6) And (3) lightly placing the beakers on the three PMMA plates in the step (2) respectively, wherein the acting force is not more than 500 g.
(7) The beaker walls were grasped and each hard paper disc was carefully rotated 360 deg., the beaker was rotated while maintaining as much as possible a pressure of 500g on the surface without lifting or applying pressure on the beaker, and the entire rotation was completed in 5 seconds.
(8) The beaker was lifted vertically up from the PMMA plate surface and the hard paper wafer was carefully removed from the beaker to avoid damage to the wafer.
(9) The anti-rub migration ability of each test article was evaluated based on the color migration on each disc. The scores were given on a scale of 1-10, with 10 being the best, i.e. no migration at all, and the scores obtained for each test sample were recorded as follows in Table 4:
| sunscreen emulsion A | Sunscreen emulsion D | Commercial sunscreen | |
| Score of | 9.0 | 4.5 | 7.0 |
Therefore, the sun-screening emulsion D without the film-forming composition is used as a negative control, and the commercially available sun-screening emulsion which is declared to be waterproof for 40min is used as a positive control, so that the composition has excellent friction and migration resistance, and the sun-screening product added with the composition can resist water and prevent too much loss of sun-screening value caused by actions such as water wiping, sweat wiping and the like, thereby avoiding the inconvenience of frequently coating sun-screening.
The embodiments of the present invention have been described in detail with reference to the examples, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention.
