Why We Love Brown Bottles and Jars.

Brown Bottles to Reduce OxidationThere are a lot of natural beauty products today packaged in clear glass bottles and jars. 

I love the way these look. The clear glass looks clean and fresh, and allows the beautiful natural colors and textures of the ingredients shine through. It's no wonder that clear glass has become so popular, especially with emerging modern-style brands. It makes a person want to pick them up, smell them, touch them, use them. They're beautiful.

So, if I love clear glass so much, why do we choose to use amber (brown) glass bottles and jars for Wunder Budder? 

Light. Or, more specifically, to block as much light as possible from getting into our products. 

Have you ever noticed that the best quality cooking oils and the best artisan beers are bottled in colored glass? This is to prevent oxidation. Oxidized oils are better known as "rancid" (beer is usually called "skunked"). Oxidized oils smell "off", and in addition to the unpleasant aroma, oxidized essential oils can cause adverse reactions on skin.

Light is only one of the causes of oxidation. There are other factors, such as exposure to oxygen in the air (reducing exposure to oxygen is one of the reasons we choose pump top closures instead of plain twist off tops for our oils) and exposure to heat. On labels of every glass bottle or jar, we suggest to "store away from direct light and heat". As a maker, I can't control where anyone keeps their products (and I of course want you to open them and use them as much as possible!), but what I can do is reduce the amount of light that enters our products, even after they're out of our hands. 

Colored glass, most commonly green, brown, and blue, slows down the rate of oxidation, allowing the product to maintain its high quality, and extends its shelf life.  Since brown has been shown to be most effective in blocking light, we choose brown glass for our packaging. 

It's not only oils (and beer!) that are affected by light, but all natural ingredients. 

If you'd like to try an experiment at home, take your favorite herb and two small clear glass jars. Put a tablespoon or two in each jar. Set one jar on a windowsill, and keep one in a cabinet. Over a few months, or maybe even weeks, you'll begin to see the sun-exposed herbs start to change. Their color, smell, and taste will fade (as well as their usefulness) as the sun breaks down their natural chemicals. The clear glass makes it easy for sunlight to get through to what it's holding inside. 

Even though products in brown glass should still be stored away from direct light and heat, the dark color offers protection for what's inside.

5 Reasons Aromatherapy Inhalers Are the Best (And a Bit of Why We Make Them)

Wunder Budder Essential Oil Aromatherapy Inhalers

I love aromatherapy inhalers.

If you've never heard of them, they are little lip balm-sized tubes with essential oils inside, and they are really cool.

They are my method of choice for using essential oils (for anything that doesn't require topical application). I started making them for myself over a decade ago, using metal refillable tubes with a salt chamber - I'd add the essential oils to the salt and the salt would help "disperse" them**. These were easy to refill, but messy and annoying to clean, so I would end up buying new ones for each blend I made.

I was using a particular blend to shorten a bad cold during a trying time (I was a full-time student, worked part-time, was planning my wedding, and trying to build Wunder Budder on the side - not an easy time for my body to fight illness), and found the blend so helpful that I had to share it...

New Year's Goals

Happy New Year

It's a brand new year!

A time for a fresh start, "365 pages, 12 chapters"
(it's the new version of "new year, new me").

Personal growth is necessary to living our best lives. Making intentional positive changes, even small ones, is how we become better people.

So many of us make resolutions to change our lives, make ourselves better, create better lives for ourselves, but so few of us keep those resolutions. It's the running joke (we all know it!) about new year's resolutions. Making big changes is hard! We have the best intentions, but keeping resolutions doesn't always work out.

One of the reasons it's hard to keep our resolutions is that ...

Wunder Budder Turns Nine!

Wunder Budder turns 9 on January 1, 2019!

Nine whole years in business (not even including the 8 part-time years before)! It's hard to believe it's been that long, because at the same time that I feel like I've done this my whole life, I also feel like I'm just getting started.

Over the past few weeks I've been thinking a lot about the beginning of Wunder Budder, back from the first salve I made in 2001-2002, to getting my first business license in 2002, to the web of events that happened over the next eight years, all leading to today, Wunder Budder's official ninth birthday. I will save most of the nostalgia for our tenth anniversary (I'm already thinking about it!), but I have a few photos to share. Look at these baby Wunder Budders from 2006, a few years before what I even call our first birthday!
