Monoi de Tahiti

What is it? Coconut oil that has been macerated with the Gardenia Tahitensis (Tiare) flowers of Tahiti.
Appearance It looks exactly like coconut oil.
Texture Smooth, thin, fast-melting oil.
Scent Strongly sweet and floral, with coconutty undertones.
Absorbency Speed Average
Approximate Melting Point 24°C
Solubility Oil
Why do we use it in formulations? Usually for fragrance; it’s so potent that you likely won’t want to use enough of it to get any other benefits (which are otherwise identical to coconut oil).
Do you need it? No
Strengths It has a very strong, tropical, floral scent. Natural floral scents are usually very expensive, so it’s a great way to get a floral scent without spending a fortune on essential oils or using artificial fragrances.
Weaknesses The scent is so strong it can be overwhelming, and fakes are abundant, so be sure you’re buying the real thing.
Alternatives & Substitutions Coconut oil can be used instead of Monoi de Tahiti in any recipe, but it will obviously be lacking the Monoi de Tahiti scent. The feel of the final product will be identical, though.
How to Work with It Include small amounts in recipes for a sweet, floral scent; if the recipe contains coconut oil just swap out a gram or two of the coconut oil for some Monoi de Tahiti.
Storage & Shelf Life Stored somewhere cool, dark, and dry, Monoi de Tahiti should last at least two years.
Tips, Tricks, and Quirks When purchasing Monoi de Tahiti, ensure the ingredients are only Cocos Nucifera Oil and Gardenia Tahitensis Flowers—there should be no added fragrances.
Recommended starter amount 100mL (3.3fl oz)
Where to Buy it  Buy it from an online DIY ingredient supplier or Amazon.

Hemp Seed Oil

What is it? A liquid oil pressed from the grains of the hemp plant.
Appearance A pale yellow to deep green liquid (the less refined versions are darker green).
Texture Smooth
Scent Quite green and grassy, a bit nutty.
Absorbency Speed Average
Solubility Oil
Why do we use it in formulations? It can help with acne, eczema, and dry skin. It’ll also turn products green, which you might like.
Do you need it? It’s not easy to find a substitution that will mimic all of its properties, so if you struggle with eczema or want to make a few recipes that use it, I’d recommend getting a small bottle.
Refined or unrefined? I like the unrefined stuff, though if you don’t like the grassy scent or dark green colour you might prefer the refined version.
Strengths It’s rich in omega-3 and omega-6 fatty acids, has antibacterial and anti-inflammatory properties, contributes a lovely green colour and a nutty/grassy scent to products.
Weaknesses Negative (though unfounded) association with marijuana, fairly short shelf life (purchase small amounts).
Alternatives & Substitutions It’s easy to match the absorption speed with something like olive oil (pomace) (USA / Canada), but you won’t be able to mimic the colour, scent, and fatty acid composition.
How to Work with It I like it in salves, balms, and body butters.
Storage & Shelf Life Stored somewhere cool, dark, and dry, hemp seed oil (USA / Canada) should last one year.
Tips, Tricks, and Quirks Unrefined hemp seed oil (USA / Canada) is quite delicate and is easily scorched; be sure to use a water bath when working with it. Hemp seed oil contains no THC (the psychoactive compound found in marijuana) so no, you will not fail any drug tests if you work with it 😉
Recommended starter amount 100mL (3.3fl oz)
Where to Buy it  Buy it from an online DIY ingredient supplier or Amazon.

Alternatives & Substitutions Rice bran oil and soya bean oil are good swaps, as are other average-to-absorb carrier oils, though it can be hard to find options as inexpensive as olive oil (pomace) (USA / Canada)!
How to Work with It I love it in soap, where it tends to make up about 40% of any bar soap recipe.
Storage & Shelf Life Stored somewhere cool, dark, and dry, olive oil (pomace) (USA / Canada) should last at least two years.
Tips, Tricks, and Quirks Olive oil is primarily composed of Oleic Acid.
Recommended starter amount 100mL (3.3fl oz)—unless you’re planning on using it in soap, in which case I’d start with at least 1L (34fl oz).
