It's been the subject of science projects, dissertations and discussions around the office water cooler: How does Static Guard® spray actually work?
It's simple science: Static Guard spray eliminates electrical charges from accumulating on things such as fabric, carpet, bedding and even your hairbrush. It does this mainly by neutralizing the charges on fabric surfaces. It also works by attracting humidity from the air, thus increasing the electrical conductivity of the fabric. Raise humidity and you lower the imbalance of positive and negative charges, and the occurrence of static cling or shock.
In 1978, Alberto-Culver, makers of Static Guard® spray, patented an anti-static spray for use by consumers. Their formula, like many lotions, moisturizers and hair conditioners, contains a neutralizing agent and humidity-attracting (hygroscopic) substances. Static Guard spray has been a great accessory ever since. |

You know it when you feel it, but what exactly is "it"? Static electricity isn't really a thing at all, but a phenomenon or event, like the weather.
Static happens when positive and negative electric charges are held apart from each other. Comb your hair on a dry day, and the comb will lift your hair away from your head without actually touching it. Maybe it cracks and snaps as the comb gets closer. That's technically not static "electricity," but rather, a static electricity occurrence.
(Next time it happens, impress friends by saying, "Wow, my hair is really full of electrostatic events today!")
This branch of science has a name: Electrodynamics. It's the study of electric charges and the way they separate and combine, and the invisible electrical fields they create. When the amounts of positive and negative electric charges in something aren't perfectly equal, electrical forces jump across space - you feel a shock or have a hair-raising experience!
Of course, to most of us what it is isn't as important as why it's happening. It has to do with temperature and humidity. To calculate the level of static electric occurrence in your area today, checkout our Static Index. |
