AIM: 

To determine the factors that influence the longevity of perfumes.
.

APPARATUS AND MATERIAL REQUIRED: 

• Three identical small perfume bottles (preferably with spray nozzles)
• Three different perfumes (of the same volume and formulation)
• Temperature-controlled environment (e.g., refrigerator, heating pad)
• Light source (e.g., desk lamp)
• Stopwatch or timer
• Distilled water
• Labeling materials
• Notebooks or data sheets for recording observations

Perfume

OBJECTIVES:

The objective of this experiment is to investigate the impact of different factors, such as temperature, light exposure, and storage conditions, on the longevity of perfumes.

PROCEDURE:

• Start by selecting three different perfumes for the experiment. Make sure they are of the same volume and formulation.
• Label the perfume bottles as A, B, and C.
• Place bottle A in a temperature-controlled environment set at a cool temperature (e.g., refrigerator).
• Keep bottle B at room temperature (around 25°C) as the control sample.
• Place bottle C in an area with exposure to light (e.g., under a desk lamp).
• Set up a timer or stopwatch to record the time.
• Spray an equal amount of each perfume onto separate test strips or small pieces of blotting paper.
• Place the test strips side by side in a well-ventilated area, away from any direct airflow.
• Observe and record the intensity of the fragrance on each test strip at regular intervals (e.g., every hour) using a descriptive scale (e.g., weak, moderate, strong).
• Repeat the observation process for several hours or until the fragrance on the test strips is no longer detectable.
• After completing the observations, transfer the perfume bottles to different conditions to study the impact of other factors. For example:

1. Place bottle A at a warmer temperature (e.g., using a heating pad) and observe the changes in fragrance longevity.
2. Store bottle B in a dark place (e.g., inside a closed drawer) to examine the effect of light exposure.
3. Place bottle C back in the original room temperature, away from light exposure.

• Repeat the observation process for each condition and record the results.
• Analyze the data collected and compare the longevity of the perfumes under different conditions.
• Draw conclusions based on the observations and data, identifying the factors that have the most significant impact on perfume longevity.

EXPECTED RESULTS:

• Temperature: Perfume stored in cooler temperatures (e.g., refrigerated) is expected to retain its fragrance for a longer duration compared to perfume stored at room temperature. Perfume exposed to higher temperatures (e.g., heated conditions) is likely to show a decrease in fragrance longevity, with the scent dissipating more quickly.
• Light Exposure: Perfume exposed to light, especially direct sunlight, is anticipated to have a reduced longevity in terms of fragrance intensity. Light exposure can cause the breakdown of fragrance molecules and alter their chemical composition, leading to a shorter-lasting scent.
• Storage Conditions: Perfume stored in a dark and cool environment is expected to have better longevity than perfume exposed to light and heat. Storing perfume in a closed drawer or in its original packaging can help protect it from light and maintain its fragrance quality for a longer period.

CONCLUSION:

It's important to note that individual perfumes may react differently to these factors, and the specific formulations and ingredients can impact their longevity. Additionally, the duration of fragrance retention may vary between perfumes, with some scents being inherently longer-lasting than others.

ADDITIONAL INFORMATION:

To draw more concrete conclusions, you should record and compare the observations of fragrance intensity over time for each condition. This will help identify the most influential factors in perfume longevity and provide insights into the best practices for storing and preserving fragrances.
