Team Lead’s name: Lucy Dowdell (but everyone put in such an amazing effort, I wish I could put everyone's name as team lead)

Name of Project with a one-sentence description: Create +, A natural scent to keep the mozzies away (and keep you smelling good)!

1. Define the problem you are seeking to solve.

We are wanting to solve the nuisance factor of mosquitoes on a day to day basis.

2. Describe your big idea (what is the vision?)

Our vision is to create a product anyone and everyone can use to repel mosquitoes effectively. Our idea entails a range of perfumes and colognes that contain eucalyptus oil, a natural ingredient that is proven to repel mosquitoes. The particularly striking aspect of our vision is it can be tailor made to suit anyone’s needs, as we will have a large range of scents available. We are aware everyone is different and therefore, would love to bring out a solution for mosquitoes that can be useful to the individual.

3. Describe and illustrate (if possible) your proposed solution.

Lemon with eucalyptus oil and coconut oil with eucalyptus oil have proven to be extremely effective against mosquitoes (Frances et al.). Coconut oil and eucalyptus oil can form a base for most of our scents, as coconut oil has a very mild smell. With this combination we can include other ingredients that have pleasant smells and repel mosquitoes. Some examples are lavender, cinnamon oil and tea tree oil. A lemon and eucalyptus oil can be a scent of its own, but we will also be combining it with some of the already mentioned ingredients.

For men, we can have mint and sandalwood scents. These blend in more naturally with the body and won’t be too overpowering. We want to create a solution that men will also be comfortable wearing on a day to day basis, so making these scents right is extremely important to us.

4. What is the core foundation of your research or solution (this could be technology, research, know-how, etc.)?

There has been quite a bit of research about what natural ingredients can repel mosquitoes. Included at the end of this document are some papers outlining this. To summarise our main research statistics: · Eucalyptus and coconut oil: 93% protection for four hours (Frances et al.) · Eucalyptus and lemon: a formula containing 32% lemon and eucalyptus oil gives 95% protection for 3 hours from mosquitos (Shyamapada Mandal)

5. Describe who you think your end-user and/or paying customer could be.

Our product’s end-users or paying customers are:

  • Individuals who want quick solution to protect themselves from mosquitoes with the convenience of a spray
  • Those who are allergic to synthetic products
  • Customers wanting to attain temporary immunity from mosquito bites but who dislike the smell of existing products
  • Customers from all genders and different age groups

6. Describe your Technology Readiness Level or Research Literature Level.

At this stage, we are at a technology readiness level of 3. We have done research to develop our idea and are now working on deciding its feasibility. We know our product could work, but we are yet to have a fully decided method.

7. Describe the top three critical hypotheses you want to explore, including:

  • How you will test them;

  • Describe your experimental plan, including any new technologies or tools to be developed; and

  • If your experiment/s in the testing phase is/are successful what are the next steps?


  1. Natural essential oils extracted from lemon, eucalyptus leaves, lavender, and cinnamon bark have mosquito repellent active ingredients.

  2. Different combination of essential oils shows increased mosquito repellent activity and less toxicity for skins.

  3. This product is environmentally friendly.

Laboratory and field experiments have to be conducted for confirming these hypotheses.

  • Essential oils extraction has to be followed using the hydro distillation of selected plant materials and test the active mosquito repellent compounds using GC/ MS (Yusufoglu, et al., 2018).

  • Conduct the bioassay tests for observing the mosquito repellent activity. Here, the individual essential oil and different combinations of those oils need to be tested (Yusufoglu, et al. 2018).

  • Conduct toxicity assay for earthworms to confirm the less harmful effect of plant essential oils against synthetic mosquito repellent such as DEET (N,N-diethyl-3-methylbenzamide) (Vasantha-Srinivasan, et al., 2018).

If these experiments succeed, we should have to follow the sensory evaluation of the selected essential oil combinations which show highest repellent activity and is environmentally friendly. Then choose the best combination which shows the highest value for sensory evaluation.

8. Describe how would use the funding to progress your hypotheses, including:

  • How will the work described be performed within the budget (up to AU$5,000) and time period (5 months) allocated for the testing phase (resources, capability, etc.)?

Of the total time period:

*2 weeks to purchase all supplies and equipment needed for hypothesis testing ($1,000)

*2 weeks to extract all oils necessary for hypothesis testing ($200)

*3 weeks to test if what oils can repel mosquitoes (and their repelling strength) and what produce organic extracts produce fragrances ($800)

*3 weeks to experiment with combinations of ingredients needed to achieve desired smell, repellant strength and impact on human skin ($600)

*2 weeks of testing to determine if the sprays are environmentally friendly ($400)

*2 weeks to to close in on final products ($400)

*2 weeks for free blind tests of samples of final products with consumers to get feedback ($500)

*2 weeks to make changes based on user feedback ($600)

*2 weeks of surplus time (if project does not meet deadlines)

  • What essential outcomes will you generate during your testing phase?

*Determine what organic oil extracts can repel mosquitos

*Determine what organic extracts can be used as fragrances

*Determine the combinations of oils and other organic extracts to be used in our products

*Determine impact of products on human skin

*Determine impact of products on environment

*Gain feedback from members of community and make changes as necessary

  • Include a brief breakdown of allowable costs.

*Ingredients to produce oils (Including back-up budget for more ingredients): $600

*Equipment required for testing: $400

*Testing: $1,500

*Backup Funds: $500

*Prepare samples of final products: $300

*Distribute samples of final products to customers: $200

*Computer software, printing, stationary and other administrative expenses: $500

*Team members and other miscellaneous expenses: $500

9. What you’ve done to date, including challenges and wins.

Earlier, our team participated and won in the Entrepreneurial Mindset workshop organized as part of the iLead+ Program by the I2N Virtual Hub. The Workshop dealt with a similar challenge of solving the global problem of mosquitoes.

The grand challenge has provided our team the opportunity to present our unique solution to the University of Newcastle.

10. Why your idea is an unconventional or creative approach to the problem.

Our idea is an unconventional and creative approach to the problem because:

We intend to use organic ingredients as part of our products which makes them more safe and skin-friendly for all age ranges over synthetic products, including young children.

Those with sensitivity to products containing synthetic ingredients will find a healthy alternative in these sprays Our products provide health benefits by repelling mosquitoes whilst also providing fragrant scents

Eucalyptus oil is our core ingredient, however, we also intend to combine it with other ingredients to create different scents that all genders and various age groups of customers will find appealing

Our solution is time-saving method to gain protection from mosquitoes (as opposed to using mosquito repellent creams and lotions)
