Essential Oils: Packaging, Blending, Company recs (Essential Oil/Aromatherapy Information)

Going through old FAQ so I am posting them (edited with additional information of course) :)

How should I package products made with essential oils (plastic or glass)? Are carrier oils okay to store in plastic or should I use glass?

For undiluted, pure essential oils, absolutes, and co2 extracts, you need to store them in colored glass (they usually come in colored glass) since many of them will eat through plastic, and it is thought by some people that toxins from plastic can leech into them (and other products/ingredients). Also it is thought that light can degrade essential oils hence the colored glass, but I know of at least one prominent essential oil company that disputes this and says uncolored glass is fine too and protects the essential oils just as well. Personally I recommend that if you are storing it in a fridge or another dark and cool place, uncolored glass would probably be fine, but if you don't, then use colored glass.

Carrier oils are fine to store and keep in plastic.

Most vendors package essential oils, absolutes, and co2 extracts in glass, if they don't, be dubious of their product, since if they are in plastic, they are probably not undiluted, but are diluted in a carrier of some sort or they are simply not the real thing. (Note: for large wholesale sizes some companies do use metal containers.  You could store them at home in lined aluminum bottles, but make sure they are lined).

But with diluted essential oils in products, it is debated whether they should be stored in plastic or glass. Personally for my own use, I usually don't package them in plastic since I've had essential oils eat through plastic before (during one of my first aromatherapy experiments over eight years ago* I had made bath salts that contained essential oils, and I had put them in a hard, plastic travel container, and it cracked the plastic in under an hour. No idea what kind of plastic it was, but it was a container made for travel). However if you dilute the essential oils very well (2% concentration or less) and use certain plastics (like PET), then short term usage (maybe only a few months) shouldn't be a problem. A lot of companies that offer shampoos and lotions and such with essential oils keep them in plastic bottles, but when I buy from other companies I always make sure I use those products up within a month or two (since many of them are also all natural and have a very short shelf life anyways).

Will mixing essential oils together in a blend (i.e. using two or more in a product) reduce their potency or 'clash' with each other?

It is thought by many aromatherapists and herbalists that combining essential oils actually improves how they work. This theory is called synergy. But keep the total essential oil content for facial formulas to 1% of under, so don't use 1% of each essential oil, but use a total of 1% or less of all the essential oils. And that's just a general rule, some essential oils should be used at way less than 1%, especially on the delicate facial and eye area.

What are some of your favorite scented products (essential oils, hydrosols, and essences) from different companies?

From AV-AT, I love Organic Ylang Ylang Complete, Organic Cocoa Absolute, and Organic High Altitude French Lavender Essential Oil. Actually any of his essential oils are wonderful, all have been fantastic: I rank them as superior quality. Their rose essential oil and absolute is the best out of any company I've tried. They are my favorite essential oil company.

Sunrose Aromatics: Peach tree leaf absolute, Organic Chocolate Peppermint Essential Oil. Yum :)

Enfleurage: Organic Petitgrain sur Fleur Essential Oil (which is distilled branches and flowers of the bitter orange tree, so kind of like a combo of petitgrain and neroli, yum!). Carries many unusual essential oils, they also have a store in New York City.

A Little Ol' Factory: Organic Bulgarian Rose alba (white rose) hydrosol (from an award winning distillery)

Nature's Gift: another superior quality company. I especially like all of their jasmine absolutes (they have three species). I've smelled jasmine from other (good to excellent) companies and while they are nice, they don't have all the notes and subtle yet complex over and under tones of the jasmines that Marge (or another superior essential oil company) carries. Offers some of the rarer essential oils.

Eden Botanicals: I have tried many of their essential oils over the years, and I love them all.  I especially like their jasmine and rose aromatics; they have several different kinds of each.  They offer superior quality products and many of the more unusual aromatics.

Samara Botane I like their rose gallica, which is a species of rose not usually used in aromatherapy (which is on super onsale now). Very fragrant. A well known and respected company. They also carry some of the harder to find essential oils.

Edited January 25, 2014: Did some minor edits (like a word here and there).  I also added a little more information on metal containers.  Rewrote a sentence about storing well diluted products in PET plastic. I removed the information on Eden Botanicals's crystallized amber since they no longer sell it.  They now sell 100% natural liquid amber (made with essential oils, absolutes, etc in a carrier oil) but I have not tried them yet (since I make my own amber bases for perfumes). Since I deleted that,  I added some information about some of my favorite current products from their company.

*In 2014, it's now been over 13 years but at the time of the original entry it was eight years so I left it as that.

Eco Living: Living green on a budget (Environmental Information)

A few days ago I finished the new Eco Living Article, which is a series of articles I write for for anb (all natural beauty) mall. This month's article is on living green on a budget. In it I've mentioned many great tips for food, clothes, and also cosmetics and soaps, as well as general green tips for how to be green (eco-friendly) while saving some green (money). Enjoy!
