Comparing Fragrance Longevity of Different Fixatives for Body Spray

Based on the information provided about the products:

• 12H Fix™ is described as being "more effective than other fixatives" and providing the "highest scent-strengthening performance" for body spray perfumes (EDT).
• Musk Fix™ and Sugar Fix™ are described as having "medium efficiency" for body spray perfumes compared to 12H Fix™.
• General musk (like Bescents X (musk)) is primarily used as a scent element to make the fragrance more gentle and fresh, rather than a dedicated fixative for extending longevity in the same way as the specialized fixatives.

Therefore, 12H Fix™ is indicated as providing better fragrance longevity compared to Musk Fix™ and Sugar Fix™, which offer medium performance. General musk is used for its scent profile rather than its fixing ability.
