How to ensure that the fragrance of space spray is long-lasting and evenly distributed?

Ensuring that the fragrance of space spray is long-lasting and evenly distributed is the key to improving user experience and product competitiveness. Here are some methods and strategies to help achieve this goal:

1. Optimize the fragrance formula
Choose high-quality fragrances: Using high-quality essential oils or fragrances is the basis for ensuring that the fragrance lasts. Natural essential oils are usually more durable than synthetic fragrances and have better stability. For example, lavender essential oil, sandalwood essential oil, etc. have strong persistence.
Adjust the fragrance concentration: According to the product positioning and usage scenarios, reasonably adjust the concentration of the fragrance. Generally speaking, the concentration between 10%-15% is a more ideal range. Too high may cause the fragrance to be too strong, and too low may not last long.
Use compound fragrances: Using a combination of multiple fragrances can enhance the layering and persistence of the fragrance. For example, combining top notes (such as citrus), middle notes (such as flowers) and base notes (such as woody fragrance) allows the fragrance to gradually show in different time periods.

2. Improve spray technology
Choose a suitable spray system: Use a high-quality spray pump or nozzle to ensure that the spray particles are fine and uniform. Ultrafine particle spray can be better suspended in the air, thus extending the diffusion time of the fragrance.
Control the amount of spray: By adjusting the pressure of the spray pump and the aperture of the nozzle, the amount of each spray can be controlled. The right amount of spray can avoid the fragrance being too strong while ensuring that the fragrance can be evenly distributed.
Develop a multifunctional spray system: For example, combined with a timed spray function or automatic sensing spray technology, the spray frequency can be automatically adjusted according to environmental conditions (such as humidity, temperature) or user needs to ensure that the fragrance is long-lasting and uniform.

3. Adding additives
Adding moisturizers: Adding an appropriate amount of moisturizers (such as glycerin or propylene glycol) to the aromatherapy spray can slow down the volatilization rate of the fragrance and prevent the fragrance from dissipating quickly in a dry environment.
Using stabilizers: Adding stabilizers (such as butylated hydroxyanisole BHA or tocopherol) can prevent the fragrance from deteriorating during storage and extend the shelf life of the product.
Adding diffusers: Using diffusers (such as polyethylene glycol) can enhance the suspension ability of fragrances in the air and make the fragrance diffuse more evenly.

4. Optimize product design
Nozzle direction design: In the packaging design, ensure that the direction of the nozzle can be flexibly adjusted to facilitate users to choose the best spray direction according to the size of the space and ventilation conditions.
Packaging sealing: Choose packaging with good sealing to reduce the volatilization of the aromatherapy liquid when it is not in use. For example, use a spray bottle with a sealed cap to ensure that the product remains stable during storage and transportation.
Multi-purpose design: Develop space sprays with multiple uses, such as combining sterilization and deodorization functions to enhance the added value and user experience of the product.

5. Optimize environmental adaptability
Temperature adaptability: In a high temperature environment, the volatilization rate of the fragrance will accelerate. The volatilization rate can be slowed down by adjusting the fragrance formula and increasing the proportion of high-boiling point ingredients.
Humidity adaptability: In a humid environment, the diffusion rate of the fragrance may slow down. The diffusion effect can be enhanced by adding an appropriate amount of alcohol or a more volatile fragrance.
Ventilation conditions: In a well-ventilated environment, the fragrance may dissipate quickly. The fragrance can be evenly distributed by increasing the spray volume or adjusting the spray frequency.
