The Importance of Sunscreen in Cosmetics

In the world of cosmetics, the use of sunscreen is a crucial step in protecting the skin from the damaging effects of sunlight. The sun's ultraviolet (UV) rays can cause a range of problems, including premature aging, sunburn, and even skin cancer. As a result, the development of effective sunscreens has become a top priority in the cosmetics industry. One of the latest innovations in sunscreen formulation is the use of nanoemulsions, which have shown great promise in providing high levels of protection while also being easy to apply and non-greasy.

Background on Avobenzone and Octil Methoxycinamat

Avobenzone is a well-known chemical that is effective in protecting the skin from UVA rays, which have a wavelength range of 340-400 Nm. On the other hand, octil methoxycinamat functions as an antidote to UVB rays, which operate in a wavelength range of 280-310 Nm. In this study, nanoemulsions were chosen as the first choice for sunscreen formulation due to their high stability, low viscosity, and transparent appearance. Additionally, nanoemulsions have a greater surface area, which allows for increased absorption of active ingredients into the skin.

Research Purpose and Methodology

The purpose of this study was to formulate avobenzone and octil methoxycinamat in the form of nanoemulsion, which is physically stable, and to measure the effectiveness of sunscreen protection from nanoemulsions compared to its emulsion preparations. This study involved three nanoemulsion formulas with variations in Tween 80 composition as a surfactant and ethanol 96% as cosurfactants, namely: (34:26), (36:24), and (38:22). Evaluation of this preparation included testing the type of emulsion, homogeneity, density, surface tension, particle size, storage stability for 90 days at different temperatures, pH, viscosity, centrifugation test, and SPF values using UV-Vis spectrophotometer.

Research Results

The results showed that Nanoemulsion F1 from Avobenzone and Metoxicinamat octils had the smallest average particle size, which is 163.31 Nm. Nanoemulsion F1 shows interesting characteristics: yellow, clear, transparent, with a distinctive odor. The test shows that the type of emulsion is M/A, with good homogeneity. The density was recorded at 1.00 g/ml and a surface tension of 43.5 dyne/cm. The stability of the preparation for 90 days is maintained at room temperature and high temperatures, but experiences the deposition of active ingredients after three days at low temperatures. Conversely, ordinary emulsions show the separation of phases after 30 days at room temperature. The Nanoemulsion F1 pH value is 7.46, with a viscosity of 75 CP. The centrifugation test results and cycling tests also showed no separation, creaming, or murky.

SPF Value and Comparison

The SPF value measured for Nanoemulsi F1 is 16.68, which is included in the category of ultra protection. As a comparison, the SPF value for the form of ordinary emulsion is 11.41, which is classified in the maximum protection category. This shows that the nanoemulsion formulation provides a higher level of protection compared to the traditional emulsion formulation.

Conclusion and Future Directions

This study concluded that Avobenzone and Metoxicinamic octils can be formulated in the form of nanoemulsion as a physically stable sunscreen for 90 days at room temperature and high temperatures, but unstable at low temperatures. The SPF value of Nanoemulsi F1 which reached 16.68 shows a higher level of protection compared to the form of its emulians. Thus, nanoemulsion can be an innovative and effective choice in the development of sunscreen products that are better for skin protection. Future studies can focus on optimizing the formulation of nanoemulsions to improve their stability and effectiveness, as well as exploring the use of other active ingredients in combination with Avobenzone and octil methoxycinamat.

Recommendations for Future Research

Based on the results of this study, the following recommendations can be made for future research:

Optimization of nanoemulsion formulation: Further studies can focus on optimizing the formulation of nanoemulsions to improve their stability and effectiveness.
Combination of active ingredients: Future studies can explore the use of other active ingredients in combination with Avobenzone and octil methoxycinamat to improve the level of protection provided by the sunscreen.

By following these recommendations, future research can build on the findings of this study and contribute to the development of more effective and stable sunscreen products that provide better protection for the skin.

Q: What is Avobenzone and how does it work as a sunscreen ingredient?

A: Avobenzone is a chemical sunscreen ingredient that is effective in protecting the skin from UVA rays, which have a wavelength range of 340-400 Nm. It works by absorbing UVA radiation and converting it into heat, which is then released from the skin.

Q: What is Octil Methoxycinamat and how does it work as a sunscreen ingredient?

A: Octil methoxycinamat is a chemical sunscreen ingredient that functions as an antidote to UVB rays, which operate in a wavelength range of 280-310 Nm. It works by absorbing UVB radiation and converting it into heat, which is then released from the skin.

Q: What is a nanoemulsion and how does it work as a sunscreen delivery system?

A: A nanoemulsion is a type of emulsion that consists of tiny droplets of oil suspended in water. It works by increasing the surface area of the skin, allowing for better absorption of active ingredients, such as Avobenzone and Octil methoxycinamat.

Q: What are the benefits of using a nanoemulsion as a sunscreen delivery system?

A: The benefits of using a nanoemulsion as a sunscreen delivery system include:
