Neem oil

What is it?

Neem oil is a carrier oil with a long history of cosmetic and skin care use in India. It is quite a polarizing oil due to its pungent scent and strong reputation for healing and helping irritated skin. Some people love it, some people can’t stand it. I’m more on the “can’t stand it” side of things, but my friend Barb loves it and has shared an entire “Stinks like A**” series on her blog starring neem oil!

Not nice. The most charitable way I can describe it is like old barbecue sauce that’s very heavy on the garlic. New Directions describes it as “Earthy, green smell with slight nutty scent towards the end.”

Why do we use it in formulations?

Neem oil has almost legendary abilities to help problematic skin—everything from acne to psoriasis to ring worm. It has been found to have antibacterial and anti-inflammatory effects. It has also been used as an insect repellant and pesticide.

Do you need it?

Definitely not. I had some, used it a few times, and got rid of it.

Refined or unrefined?

I’ve only seen unrefined neem for sale.

Strengths

Antibacterial and anti-inflammatory effects; good for irritated skin.

Weaknesses

It stinks. Badly. It’s detectable at even 1%.

Alternatives & Substitutions

There’s really nothing that’s a suitable trade out, but given its typically low usage rate I would likely replace it with another liquid oil and some essential oils that have similar properties.

How to Work with It

Include neem oil in the oil phase of your formulations; it can be hot or cold processed.

Storage & Shelf Life

Stored somewhere cool, dark, and dry, neem oil should last up to two years.

Tips, Tricks, and Quirks

If you are considering purchasing some I highly recommend you smell it at a store before buying it. Neem oil should be avoided by pregnant women.

Recommended starter amount

30mL (1fl oz)

Where to Buy it

 Buy it from an online DIY ingredient supplier or Amazon.
