Odor-reduction performance
Users may independently evaluate performance under varying conditions, including clothing, activity level, laundering practices, temperature and humidity.
Household open engineering
Open Deodorant Project
A public experimental disclosure of a simple, low-waste starch formulation for independent evaluation.
Important: The starch deodorant technology described here is the property of Oobleq Ltd. Experimental formulation information is made publicly available for informational and experimental purposes only, without claims regarding safety, suitability, effectiveness, merchantability or fitness for any particular purpose. Users assume all responsibility for preparation and use.
Dry blend
1 : 16
1 part instant clear-gel modified food starch
16 parts arrowroot starch
Blend thoroughly and store dry in a sealed container.
Preparation and use
Experimental formulation
- Measure approximately 1/4–1/2 teaspoon of the dry blend.
- Add several drops of water and mix to form a thin slurry.
- Apply a thin, even layer to the axillae (under arms) and allow it to dry briefly.
Independent evaluation
Variables worth observing
Interaction with flying insects
Users may also evaluate possible reduction in mosquito bites and other interactions with flying insects, which may be attracted by volatile organic compounds associated with axillary malodor.
Project backstory
Simple, accessible and low-waste.
This work originated from an interest in reducing unnecessary packaging, simplifying formulations and exploring low-cost public-access household technologies. The formulation disclosure is publicly available so that individuals can examine and evaluate the approach independently.
Support the work
The technology is shared freely. The book is the tip jar.
If you appreciate this kind of independent design and public-access experimentation, please consider purchasing the Triangle Origami Book. The book is a substantial collection of original paper-engineering designs—not a donation receipt—and its sales help support continued independent work.
