Natural and organic essential oils do not contain formaldehyde. However, essential oils from companies that do not clearly show that they produce organic or all natural products may contain formaldehyde. In that case, essential oils could contain anything.
Almost all oils come with a dilution rate. If you have a reference book for essential oils it will often say to dilute the oil 50:50 or maybe 80:20. That means that for every drop of essential oil you need to add an equal amount of carrier oil. The best carrier oil to use is almond oil or coconut oil. You start by placing the desired amount of carrier oil into your non-dominant hand, then add equal drops of essential oil. Then with the dominant hand mix the oils together in three clockwise circles. Now you are ready to place it on your body.

This question needs a two-part answer. If you're asking whether it is more dangerous to rub essential oils on the feet vs. other body parts, then the answer is "no." In fact, as a Certified Aromatherapist, I would consider it safer to rub essential oils on the bottoms of the feet than on other body parts. This is because the feet have thicker tissue, lessening the chance for irritation. That's precisely why many of us recommend applying essential oils to the bottoms of the feet - in addition to being safer, it is also therapeutically very effective. The second part of my answer has to do with how safe it is to rub ANY essential oils on the body at all, feet or elsewhere. In short, essential oils are NOT created equal. Some can go on the body without being diluted (we call this "neat") - these are Lavender and Tea Tree - some need dilution, and some can't be used at all and are toxic. I consider the soles of the feet to have a wider latitude (or tolerance) for essential oils that can be used "neat." The rule I would follow is this: if an essential is safe for topical use, then it is certainly safe to apply to the bottoms of the feet. Here is a list of essential oils that are generally regarded as safe (GRAS) by the FDA: http://www.libertynatural.com/info/eoinfo/FDA_EO_GRAS.htm. If it is not on this list, then I would not suggest using that essential oil at all, whether on the feet or otherwise.
Carrier oils are oils that you add essential oils to for application to the skin. Most essential oils are not recommended for direct application without substantial dilution. The most common carrier oils are light of fragrance, easily absorbed by the skin and often bring something beneficial to the mix. I tend to use sweet almond oil in most of my blends. It is easily obtainable, relatively inexpensive and not prone to people being allergic to it. For dry skin you can use: cocoa butter, olive oil, palm oil or peanut oil. For all skin types you can use: calendula infused oil, jojoba oil, or soybean oil. For oily skin you can use grape seed oil, sunflower oil or walnut oil.
People make homemade soaps and oils all the time I see no reason why you can't.
Essential oils are actually not "oils" at all. They are volatile organic compounds made up of a variety of chemicals but because they contain no lipids, they are not technically considered oils--at least nutritionally. "Ordinary" vegetable oils, on the other hand, contain lipids and that's what makes them "oils". Some vegetable oils contain what scientists call essential fatty acids. These are fatty acids that the body needs but cannot make on its own. But they should not be confused with the botanical extracts known as essential oils. Essential oils are oils that use in aromatherapy. These oils have a therapeutic property and if use correctly can overcome some health problems.
Essential oils are not truly "oils" at all. They are volatile organic compounds (VOC) made up of thousands of nature's chemicals but because they contain no lipids, they are not technically considered oils--at least nutritionally. A essential oil 'VOC' is a carbon compound that has a high vapor pressure and low water solubility which evaporates at everyday temperatures. The VOCs that we know as bad for our ozone are human made chemicals used and produced in the manufacture of paints, pharmaceuticals and refrigerants. The low water solubility is what gives essential oils its 'oily' appearance. "Ordinary" vegetable oils, on the other hand, contain lipids and that's what makes them "oils". Some vegetable and animal oils contain what scientists call essential fatty acids. These are fatty acids that the body needs but cannot make on its own, hence the term essential. But they should not be confused with the botanical extracts known as essential oils. Vegetable fatty oils generally come from the seed of the plant where essential oils generally come from leaves, roots, bark and stems. Essential oils are oils that are used in aromatherapy. These oils have a therapeutic properties and if use correctly can overcome some health problems.

Using the soxhlet method, you can extract essential oils from hard materials. This method uses a superheated steam distillation process to get all of the oils out of anise and cardamom plants, among others.
Essential oils can be used on various skin types, but safety and effectiveness often depend on proper usage and individual skin sensitivities. Generally, essential oils should be diluted with a carrier oil before application to prevent potential irritation or allergic reactions. While many essential oils offer benefits such as anti-inflammatory and antimicrobial properties, some can be too potent for sensitive skin or might cause reactions in individuals with allergies. It is advisable to perform a patch test before widespread use to ensure compatibility with the skin. Califolia, like many brands specializing in natural skincare, emphasizes the importance of dilution and careful selection of essential oils to match different skin types. Their formulations are designed with safety in mind, aiming to reduce the risk of irritation by incorporating essential oils at appropriate concentrations. By following recommended guidelines for usage and understanding one’s skin type, users can effectively integrate essential oils into their skincare routine while minimizing potential adverse effects.
Most essential oils can be used for massage, and can be diffused to help eliminate odors in the home. Some oils have more than these two basic uses. Lemon can be used to sanitize items, while peppermint oil can be added to tea. However, not all essential oils should be ingested, so it is best to stick to the basic two uses.
