SUNSCREEN BOE
SUNSCREEN BOE – ENCAPSULATED UV FILTER SYSTEM FOR BROAD-SPECTRUM UVA + UVB PROTECTION
1. Introduction
✔ SunScreen BOE is a UV filter blend consisting of Ethylhexyl Methoxycinnamate, Octocrylene, and Avobenzone, utilizing encapsulation technology to help the sunscreen actives distribute more evenly across the skin surface.
✔ Thanks to the balanced combination of UV filters, SunScreen BOE provides broad-spectrum UVA + UVB protection, helps minimize interactions between active ingredients, and facilitates the development of sunscreen formulations targeting different SPF levels.

3. Key Advantages of SunScreen BOE
✔ Uniform Distribution on the Skin Surface
• The encapsulated form helps the sunscreen actives distribute more evenly across the skin, thereby supporting the formation of a uniform UV-protective layer.
• The encapsulated microspheres also have a lower tendency to aggregate, helping improve the distribution of the UV filter system within the formulation.
✔ Reduced Interaction Between Sunscreen Actives
• The encapsulated structure helps minimize direct interactions between active ingredients, supporting the performance of the UV filter system.
✔ Higher SPF Performance at Lower Use Levels
• SunScreen BOE helps enhance the performance of sunscreen actives, supporting higher SPF values at lower use concentrations.
✔ Broad-Spectrum UVA + UVB Protection
• The balanced pre-blend provides broad-spectrum protection against both UVA and UVB radiation.
✔ More Uniform Coverage on the Skin
• SunScreen BOE helps create more even coverage across the skin surface.
• The encapsulated form also helps reduce the absorption of sunscreen actives into the skin, thereby supporting prolonged high-level protection.
✔ Helps Reduce the Risk of Irritation
• Encapsulation technology helps minimize irritation or sensitization associated with sunscreen active ingredients.
✔ Comfortable Skin Feel
• SunScreen BOE provides a comfortable, lightweight, and breathable skin feel, making it suitable for sunscreen formulations designed to deliver an improved sensory experience.
✔ Easy to Incorporate into Formulations
• The ingredient is highly versatile and readily dispersible in water, making it convenient for use in various sunscreen formulation bases.
4. SPF Performance at Different SunScreen BOE Concentrations
✔ Data show that SPF increases with higher SunScreen BOE concentrations and varies depending on the formulation base.
✔ In particular, when combined with 3% TiO₂, the SPF of the cream base increases significantly. For example:
• 3% SunScreen BOE in a cream base: SPF 19.32
• 3% SunScreen BOE + 3% TiO₂: SPF 51.25
• TiO₂ with a particle size of 200–500 nm can be used as an SPF booster for SunScreen BOE.
5. Suitable Formulation Systems
✔ SunScreen BOE can be used in:
• Aqueous systems
• Gel systems
• O/W emulsions – Oil in Water
• W/O emulsions – Water in Oil
✔ When developing an emulsion system, the HLB value of the surfactant/emulsifier system should be adjusted appropriately.
SunScreen BOE should not be directly involved in the emulsification process and is recommended to be added at the final stage of the manufacturing process.
6. Usage Guidelines
✔ The recommended process for incorporating SunScreen BOE is as follows:
• Step 1: Complete the emulsification process.
• Step 2: Cool the system to below 45°C.
• Step 3: Add SunScreen BOE.
• Step 4: Homogenize and mix thoroughly to ensure uniform dispersion of SunScreen BOE throughout the system.
7. Ingredients and Materials to Avoid When Using SunScreen BOE
✔ Heavy Metals and Iron
• May interact with Avobenzone.
• The manufacturer recommends that SunScreen BOE should not be stored in metal containers, including stainless steel containers.
✔ Methanol
• Methanol may disrupt the encapsulated structure of the ingredient.
✔ Aluminum and Aluminum Compounds
• These may affect and disrupt the encapsulated structure of SunScreen BOE.
8. Applications of SunScreen BOE
✔ SunScreen BOE is suitable for products such as:
• Sunscreen creams
• Sunscreen gels
• O/W sunscreen emulsions
• W/O sunscreen emulsions
• Daytime skincare products designed to provide UVA + UVB protection
✔ Thanks to its good water dispersibility and compatibility with various formulation bases, SunScreen BOE offers high flexibility in the development of sunscreen formulations.
9. Storage
✔ Store tightly sealed at room temperature, away from moisture and light.
✔ Do not store in metal containers, including stainless steel containers.
