Description

Organic sunscreen composition with good photostability

Technical Field

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

Background

Consumers desire sunscreen products that maintain high levels of uv protection while also providing long lasting effectiveness and safety. The organic sun-screening agent is in transition to an excited state after electrons in the excited state absorb photons through electron energy level transition, then energy is released through fluorescence, heat energy or phosphorescence emission and the like to finally return to a ground state, and ultraviolet protection is realized through the circulation to resist ultraviolet rays, generally ultraviolet rays in a specific wave band. However, some organic sunscreens have the potential for photostability, and under the irradiation of ultraviolet rays, the organic sunscreens may undergo isomerization or cleavage after absorbing photons, and degrade themselves, thereby reducing or losing the ability to absorb ultraviolet rays and even causing skin irritation, and reducing long-term effectiveness and safety in the application process of the product.

Current light stability combinatorial studies on organic sunscreens have focused mainly on ensuring that target SPF and PA values are achieved. US 5,576,354 uses OCR in combination with BMDBM to improve BMDBM light stability. Halstar (US 5,993,789) and Merck have related studies reporting the use of diethyl hexyl 2, 6-naphthalate and diethyl hexyl butylidenimalonate, respectively, to stabilize avobenzone. In addition, some sun protection products are also marketed which claim to use light stability technology to provide long lasting sun protection. These solutions are mostly aimed at specific unstable organic sunscreens by improving their photostability through the addition of stabilizers or antioxidants.

Therefore, there is an urgent need in the art to find new ideas to avoid the additional formulation cost increase caused by the addition of stabilizers, the possible presence of stabilizers from serious toxic side effects or the addition of partial antioxidants may even lead to discoloration problems of the formulation upon illumination, and the effect of a single light stabilizer on compatibility, migration, volatilization, etc. reduces its theoretical efficacy.

The following illustrates solvent methods that may be used to screen solvents, particularly oil-soluble sunscreens, but are not limited thereto.

The dissolution test of the crystalline organic sunscreen agent is that a part of the crystalline organic sunscreen agent must be dissolved in a proper solvent, a single crystalline sunscreen agent is heated to 80-85 ℃ to be dissolved in a solvent (grease), 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 without recrystallization), the appearance of the solution is observed to have no crystal precipitation, and a proper solvent suitable for testing the organic crystalline sunscreen agent is screened. For example, crystalline sunscreen EHT, BMDBM, DHHB, DBT, BEMT is mixed with diisopropyl sebacate, dibutyl adipate and dimethyl capramide according to a mass ratio of 1:5, heated to 80-85 ℃ and stirred to be dissolved to be transparent, cooled to room temperature, placed in a refrigerator at 0 ℃ (about) for about 12 hours, then returned to room temperature and placed for 12 hours, (0 ℃/RT) for 8 times, and precipitation of the sunscreen is observed, and the dissolution results are shown in the following table 2:

TABLE 2

When DIS alone, BEMT precipitated in the third cycle. And after using DIS/DMDA (23:2) as a mixed solvent, carrying out OK for 8 times, and finally selecting a DIS+DMDA composite solvent and a DBA composite solvent as grease used in a test formula.

Solubility experiments were performed on combinations of organic sunscreens (each combination using the same combination of oils) to ensure that the crystalline sunscreens were completely in solution in the test formulation without precipitation. For example, the following organic sunscreens are combined in the combination scheme shown in Table 3 below:

TABLE 3 Table 3

The composition formed by the oil-soluble organic sunscreens is mixed with the solvent shown in the table, heated to 80-85 ℃ and stirred for uniform dissolution, cooled to room temperature to be transparent liquid, then placed in a refrigerator, circulated for 8 times at 0 ℃ for 12 hours/RT, and the appearance of the solution is observed to be free from crystal precipitation. The grease combinations shown in the table are shown to dissolve well the compositions formed by the respective organic sunscreens.

Light stability test method for a single sunscreen or a combination of sunscreens in the following test examples:

test samples were prepared using each sunscreen in a single sunscreen or a combination of sunscreens separately in the same formulation base. Uniformly coating an equal amount of test sample on a quartz plate, irradiating the coated plate by using a sunlight simulator with a light source of CLEO HPA400S and a light intensity of 6.7mW/cm ², respectively irradiating for 3min, 6min, 9min, 12min, 15min, 20min, 25min and 30min, calibrating by using a blank control sample (namely, cream with the same matrix without a sun-screening agent; the influence of the matrix can be avoided by using the blank sample calibration), measuring the ultraviolet absorption of the coated plate before and after irradiation by using an ultraviolet spectrophotometer (instrument model: SHIMADZU UV-2700), and recording the change of absorbance values.

And calculating the absorbance value of each sunscreen agent at the maximum absorption peak, and scanning an absorption curve in the range of 290-400nm by an ultraviolet spectrophotometer when the combination test of the sunscreen agents is performed, and selecting the absorbance value at the maximum absorption from the absorption curve.

The initial absorbance value, namely the absorbance value before irradiation is marked as A0, the absorbance value after illumination is marked as A1, and the absorbance value reduction rate delta A after illumination for different time is calculated by the following steps:

ΔA＝1-A1/A0*100％

the larger Δa represents more photodegradation and the worse the photostability.

Test example 1

Single sunscreen photostability test

The 13 organic sunscreens were each tested with grease (e.g., DIS/DMDA complex solvent or DBA) according to the following formulation of table 4:

TABLE 4 Table 4

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

The measured results are shown in Table 5:

TABLE 5

The negative numbers in the table are because the sunscreen agent has very good photostability and basically no degradation, but the light absorption value is slightly higher than the initial value due to the normal error in the experiment, and the negative values are obtained through a calculation formula.

Preferably, the absorbance value is reduced by less than 30% after 3min irradiation, and the absorbance value is reduced by less than 30% after 30min irradiation.

In the case of using DIS/DMDA as a solvent, the absorbance decrease rate of PBSA, MBBT, PS, EHT, BEMT, OCR, DHHB, EHS, TDSA is lower than 30%, and the absorbance decrease after 3min irradiation of TDSA is higher.

In the case of using DBA as a solvent, the absorbance value reduction rate of PBSA, MBBT, EHS, TDSA, EHT is lower than 30 percent, but the absorbance value reduction rate after the TDSA is irradiated for 3 minutes is higher; the combination of two solvents preferably gives 8 sunscreens with good relative UV stability: PBSA, MBBT, PS15, EHT, BEMT, OCR, DHHB, EHS.

Since OMC has better solubility and cost performance, in recent years, with the change of national sun protection mark 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 designing a high protection sun protection formula, so DBT is increased as an alternative according to the test result of single sun protection agent.

Final selection: PBSA, MBBT, PS15, EHT, BEMT, OCR, DHHB, EHS, OMC, DBT sunscreens were screened into the combination.
