• 질문:

  Why is Octyl 4-Methoxycinnamate used in sunscreen formulations?

  답변: It is an oil-soluble organic UVB absorber that helps protect the skin from UVB radiation. It is commonly used in sunscreens, sun care, lip care, and other personal care products, often together with UVA filters to build broader spectrum protection.
• 질문:

  Is Octyl 4-Methoxycinnamate water soluble?

  답변: No. It is practically insoluble in water and is used as an oil-soluble liquid UVB filter. This makes it suitable for oil-phase incorporation and water-resistant sunscreen systems, but it should be evaluated for compatibility in the target emulsion.
• 질문:

  How is Octinoxate different from UVA filters such as avobenzone?

  답변: Octinoxate is primarily a UVB filter, while avobenzone is primarily a UVA filter. In many sunscreen systems they are combined with other filters and stabilizers to achieve broad-spectrum UV coverage, rather than being treated as equivalent replacements.
• 질문:

  What concentration limits should be confirmed for sunscreen use?

  답변: Limits depend on the region and product category: US OTC sunscreen use is commonly limited to 7.5%, while EU cosmetic regulation generally permits up to 10% under Annex VI. Confirm the current local regulation, product type, dosage, and combined-filter exposure limits before formulation.
