The composition comprises the following components: 1-9 parts of octocrylene, 2-5 parts of ethylhexyl salicylate, 0.5-5 parts of polysiloxane-15, 0.5-2 parts of ethylhexyl triazone, 1-4 parts of diethylamino hydroxybenzoyl hexyl benzoate, 1-2.5 parts of bis-ethylhexyloxyphenol methoxyphenyl triazine, 0.5-4 parts of phenylbenzimidazole sulfonic acid and 0.5-5 parts of methylene bis-benzotriazolyl tetramethylbutyl phenol.

Description

Organic sunscreen composition with good light stability

Technical Field

The invention relates to the field of daily-use chemical industry, in particular to an organic sunscreen agent combination scheme with good light stability.

Background

Consumers desire sunscreen products that maintain effective uv protection while also being long lasting in effectiveness and safety. The organic sunscreen agent is transited through an electronic energy level, electrons in an excited state are transited to the excited state after absorbing photons, then energy is released through the modes of releasing fluorescence, heat energy or emitting phosphorescence and the like and finally returns to a ground state, and the ultraviolet ray resistance is realized through the circulation, and the ultraviolet ray protection is realized through the ultraviolet ray in a specific waveband generally. However, some organic sunscreens have the hidden trouble of light stability, and under the irradiation of ultraviolet rays, the organic sunscreens may be isomerized or cracked after absorbing photons, and are degraded to reduce or lose the capability of absorbing ultraviolet rays, even cause skin irritation, and reduce the long-term effectiveness and safety of the product in the application process.

Current combined studies on the photostability of organic sunscreens focus primarily on ensuring that the target SPF and PA values are achieved. US 5,576,354 uses OCR in combination with BMDBM to improve BMDBM photostability. Hallstar (U.S. Pat. No. 5,993,789) and Merck have related studies reporting the stabilization of Avobenzone using diethylhexyl 2,6-naphthalate and diethylhexyl syringylidenemalonate, respectively. In addition, some sunscreen products are also declared to provide lasting sunscreen by adopting light stability technology. These solutions are directed to improving the photostability of certain unstable organic sunscreens by adding stabilizers or antioxidants.

Therefore, there is an urgent need in the art to find new ideas, which avoid the additional formulation cost increase caused by adding stabilizer, the possibility of severe toxic and side effects of stabilizer or partial antioxidant addition, even the possibility of formulation discoloration problem in light, and the theoretical efficacy of single light stabilizer is reduced due to compatibility, migration, volatilization and the like.

The following illustrates, but is not limited to, solvent methods that can be used to screen for solvents, particularly oil-soluble sunscreens.

The method of the dissolution test of the crystalline organic sunscreen agent is that the partially crystalline organic sunscreen agent must be dissolved in a proper solvent, the single crystalline sunscreen agent is heated to 80-85 ℃ and dissolved in the solvent (grease), after the temperature is reduced to room temperature, the obtained sample is circulated for 8 times at 0-12 h/RT-12h (namely, the circulation is carried out at 0 ℃ and room temperature to ensure that the sunscreen agent is completely dissolved and no recrystallization occurs), the appearance of the solution is observed to have no crystal precipitation, and a proper solvent suitable for the test of the organic crystalline sunscreen agent is screened. For example, crystalline sunscreens EHT, BMDBM, DHHB, DBT, BEMT are mixed with diisopropyl sebacate, dibutyl adipate, and dimethyldecanamide in a mass ratio of 1:

TABLE 2

BEMT appeared precipitated during the third cycle when DIS was used alone. And after DIS/DMDA (23).

Solubility experiments on combinations of organic sunscreen agents solubility experiments were performed on the organic sunscreen agent combination protocol (using the same combination of oils and fats for each combination) to ensure that the crystalline sunscreen agent was completely dissolved in the test formulation without precipitation. For example, the following organic sunscreens are combined, for example, in the combination scheme shown in table 3 below:

TABLE 3

The composition formed by the oil-soluble organic sunscreen agent is mixed with the solvent shown in the table, heated to 80-85 ℃, stirred and dissolved uniformly, cooled to room temperature to form transparent liquid, and then placed in a refrigerator, and the temperature is 0 ℃,12 hours/RT, 12 hours and circulation are carried out for 8 times, and the appearance of the solution is observed to have no crystal precipitation.

The photostability test method of the sunscreen agent alone or in combination in the following test examples:

test samples were prepared using each sunscreen alone or in combination with a single sunscreen in the same formulation matrix. Uniformly coating the same amount of test sample on a quartz plate with a light source of CLEO HPA400S and a light intensity of 6.7mW/cm ² The coated panel was irradiated with sunlight for 3min, 6min, 9min, 12min, 15min, 20min, 25min, and 30min, respectively, calibrated with a blank control (i.e., a cream of the same substrate without sunscreen agent; calibration with a blank sample can avoid the influence of the substrate), measured for ultraviolet absorption before and after the irradiation with an ultraviolet spectrophotometer (instrument model: SHIMADZU UV-2700), and the change in absorbance was recorded.

And (3) calculating the light absorption value at the maximum absorption peak of each sunscreen agent, scanning an absorption curve in the range of 290-400nm by an ultraviolet spectrophotometer during the combination test of the sunscreen agents, and selecting the light absorption value at the maximum absorption position from the absorption curve.

The initial absorbance value, namely the absorbance value before irradiation is recorded as A0, the absorbance value after illumination is recorded as A1, and the absorbance value reduction rate delta A after different times of illumination is calculated by the following method:

ΔA＝1-A1/A0*100％

the larger Δ a represents the more photodegradation and the worse the photostability.

Test example 1

Single sunscreen photostability test

13 organic sunscreens were tested by proofing with grease (e.g., DIS/DMDA complex solvent or DBA) according to the following formulation in Table 4:

TABLE 4

Heating phase A to 80-85 deg.C, and stirring; heating the phase C to 80-85 deg.C, and stirring. Adding phase A to stir and dissolve uniformly when phase B is an oil-soluble sunscreen agent, and adding phase C to stir and dissolve uniformly when phase B is a water-soluble sunscreen agent (PBSA needs to be neutralized by tromethamine until pH is about 7.2); slowly adding the phase A into the phase C, homogenizing at 5000rpm for 2-5min, stirring, cooling to room temperature, detecting, and discharging.

The results are shown in Table 5:

TABLE 5

The negative number in the table is because the light stability of the sun-screening agent is very good and basically has no degradation, but the light absorption value is slightly higher than the initial value due to normal error in the experiment, and the negative value is obtained by a calculation formula.

Preferably an organic sunscreen agent with an absorbance value decreasing less than 30% after 3min irradiation and an absorbance value decreasing less than 30% after 30min irradiation.

When DIS/DMDA is used as solvent, the decrease rate of the absorbance values of PBSA, MBBT, PS15, EHT, BEMT, OCR, DHHB, EHS and TDSA is lower than 30%, and the decrease of the absorbance values after 3min irradiation of the TDSA is higher.

When DBA is used as a solvent, the reduction rate of the absorbance values of PBSA, MBBT, EHS, TDSA and EHT is lower than 30%, but the reduction rate of the absorbance values after 3min irradiation of the TDSA is higher; by combining two solvents, 8 sunscreens with better relative ultraviolet stability are preferably selected: PBSA, MBBT, PS15, EHT, BEMT, OCR, DHHB, EHS.

Due to the fact that OMC has better solubility and cost performance, in recent years, with the change of national sun protection marking laws and regulations, the market demand of sun protection products with high protection value is increased, and the selection of sun protection agents is generally increased when high protection sun protection formulations are designed, so that DBT is increased as an alternative according to the test result of a single sun protection agent.

And (3) final selection: PBSA, MBBT, PS15, EHT, BEMT, OCR, DHHB, EHS, OMC, DBT 10 sunscreens.
