Essential Oil Candles, Cold Diffusion and Palo Santo | Bloom Skin

Bloom Skin started with skin, and that is still where most of my thinking goes. But somewhere along the way the products stopped being only about what goes on your face and started being about the ten minutes around them as well. The balm at the end of a long day. What the room smells like while you use it. The fact that you have to stop and pay attention to yourself for a moment, even a short one.

 

Sanctuary is where that side of things lives. Candles, cold diffusion, reed diffusers, and the pieces that sit out on a shelf rather than in a cupboard. Same approach as everything else I make, which means raw materials I understand, nothing in there for the sake of it, and a straight account of what it does and what it doesn't.

 

 

Why essential oils, when fragrance oils would be so much easier

 

I want to start with the awkward part, because it is the honest one.

 

Fragrance oils are engineered for exactly this job. They are built to survive heat, to fill a room, and to smell more or less identical in the last hour of the burn as they did in the first. Pure essential oils are not built for any of that. They are plant materials with their own opinions.

 

So an essential oil candle behaves differently, and you should know that before you buy one. The scent throw is gentler. It will fill the room you are sitting in rather than announce itself from the hallway. The scent also shifts as it burns, because the lighter citrus and floral constituents lift off faster than the woods and resins underneath them. Some people find that a flaw. I find it one of the more interesting things about them, because a blend that changes over three hours is doing something a synthetic one cannot.

 

They are also considerably more expensive to make. Sandalwood alone costs more per bottle than most of what goes into the rest of the range, and there is no way around that if you want it in the blend.

 

I use them anyway, for the same reason I use them on skin. I know what is in them, I know where they came from, and I like working with them. If what you want is a candle that perfumes an entire house, I would honestly point you towards a fragranced one. That is not what these are.

 

One thing worth mentioning while we are here. Candles carry CLP labelling, and mine declare their allergens in full. Green Calm names linalool and linalyl acetate on the product identifier, with a longer allergen list underneath. That is not a warning sign hidden in small print, it is the law working exactly as intended, and I would be more suspicious of a natural candle that declared nothing at all. I've written about essential oils and allergens properly here if you want the longer version.

 

 

Green Calm, and why it took so long

 

Green Calm is led by rose geranium, with petitgrain, neroli, bergamot, lemon and sandalwood layered underneath it. Green and floral at the top, soft and grounded at the base.

 

It went through a lot of versions. I tested wick sizes through five different gauges, adjusted the essential oil load down when the first blend came out too loud, and reworked the balance more times than I want to admit to.

 

The single biggest thing I got wrong early on was testing too soon. I was burn testing at twenty four hours after pouring, deciding the scent was weak, and reformulating on the strength of that. Wax needs to cure. Once I started testing at two weeks instead, the same blend I had almost given up on was exactly right. If you make candles yourself, that is the piece of advice I would hand over first.

 

 

Coconut and rapeseed wax, and an honest word about wax generally

 

My candles are poured in a coconut and rapeseed blend, scented with pure essential oils and nothing else.

 

Both waxes are renewable plant crops. Rapeseed is grown across Europe, which keeps the supply chain shorter than it would otherwise be. Coconut burns cool and very clean, and holds essential oil well. Together they give a smooth, even burn, minimal soot and a creamy finish that stays looking good all the way down.

 

The comparison people usually want is with paraffin, which is a byproduct of crude oil refining. Studies do consistently find that paraffin produces more soot and a wider range of aromatic compounds than plant waxes under comparable conditions. What is genuinely still debated is how much that matters at normal levels of use in a home, and I am not going to tell you a paraffin candle is poisoning you, because I don't think the evidence supports saying it that strongly. What I can say is that when I had a choice between a petroleum byproduct and a plant crop, the plant crop fit what I am trying to build.

 

Soy sits somewhere in the middle. It is renewable and it performs well, but a lot of it is genetically modified and grown with heavy pesticide use, and it is almost always sold as a blend anyway.

 

Here is the part most candle brands leave out. Wax matters less than the marketing suggests. What actually decides whether your candle burns cleanly, throws its scent and lasts is the wick, the vessel, and how you burn it. A beautifully sourced wax with the wrong wick in it is still a bad candle.

 

 

How to get the most out of it

 

A few things worth knowing, and I want to start with the one that trips people up, because most of the candle advice online was written for paraffin and does not apply here.

 

Don't panic if the first burn doesn't reach the edges. You will read everywhere that if the melted pool doesn't spread the full width on the very first burn, the candle is ruined and will tunnel forever. With plant waxes that simply isn't true. It is completely normal for a natural wax candle to leave a ledge around the sides for the first burn or two. As the candle burns down the vessel holds more heat, and that ledge melts back and levels itself out.

 

That ledge is doing something useful, too. Wax sitting up the sides insulates the vessel, which matters most in the last third of the candle when the flame is closest to the base and the glass is at its warmest. It isn't a fault waiting to be corrected. Left alone, it works in your favour.

 

Give it a decent stretch, then stop at four hours. Two to three hours lets the scent build properly. Past four the vessel gets hot and the flame starts drowning in its own wax.

 

Trim the wick to about five millimetres before every burn. An untrimmed wick gives you a taller flame, more soot and a faster burn.

 

Keep it out of a draught. An open window or a busy doorway pulls the flame sideways and gives you an uneven burn and soot marks up the glass.

 

My 240g amber glass candle gives around forty five hours if you treat it that way.

 

 

Cold diffusion, and scenting a space properly

 

A candle scents the room you are in. Scenting a whole studio, salon or shop is a different problem, and cold diffusion is how it is actually done.

 

The machine uses pressurised air to break the oil into an extremely fine dry mist, particles measured in microns, which then disperses through the space. No heat and no water anywhere in the process. That matters more than it sounds. Heat alters the oils and changes what you end up smelling. Water dilutes the blend, adds humidity, and gives you something that needs cleaning regularly. Cold diffusion leaves the blend as it was made, covers far more ground than a candle can, and leaves no residue on your surfaces.

 

I make my diffusion liquid on a bio based solvent derived from glycerine. I chose it because it is low odour and low VOC, so it carries the blend without adding a smell of its own underneath it. Anyone who has used a cheaper base and caught a faint chemical note behind the scent will know exactly what I mean.

 

This is something I make, and something I'll develop for a business that wants a scent of its own. It starts as a conversation about what the space is for and how you want people to feel when they walk into it, and the blend is built from there rather than picked off a list. Once it's running, I supply the refills.

 

If you run a studio, salon, clinic, shop or holiday let and you would like a scent developed for your space, email me at support@bloom-skin.co.uk and I'll send over the details. I'm happy to talk through what would suit before anything is committed to.

 

 

Reed diffusers, coming soon

 

Reed diffusers are next, in the same blends, in a stone coloured ceramic vessel. They do a different job to a candle. No flame, no supervision, and a low steady scent that sits in the background of a room all day. Good for a hallway, a bathroom, or anywhere you want something continuous rather than an occasion.

 

They are in development now. If you want to know when they land, the newsletter is the place to be.

 

 

Palo Santo, and what it actually smells like

 

Palo Santo is warm, sweet and resinous, with a bright citrus edge sitting over the top of it. If frankincense and a sweet orange had a very calm conversation, it would smell roughly like that. Which makes sense, because Palo Santo belongs to the same botanical family as both frankincense and myrrh.

 

The part I find genuinely remarkable is where the scent comes from. Living Palo Santo wood is almost scentless. The aromatic compounds only develop after the tree has died naturally and the wood has rested on the forest floor for years while it slowly breaks down. Commonly three to ten years, sometimes longer. Nobody can rush it. What you are smelling is the result of a decade of waiting.

 

Chemically it is dominated by limonene, with alpha terpineol alongside it. And here is where I want to be careful, because Palo Santo attracts more overclaiming than almost anything else in this corner of the industry.

 

What I can't give you is human research showing what burning it does to how you feel, because that research doesn't exist. Palo Santo has simply never been through that kind of study. So rather than dress something up, I'll say plainly that the evidence isn't there, and tell you what I do have instead.

 

There is a long tradition of use across Andean and Amazonian cultures that deserves respect on its own terms. That is not the same category of evidence as a controlled trial, and it should not be dressed up as one, but it is not nothing either.

 

And then there is my own experience, which is the weakest evidence of the lot and I know it. I light it when I want to mark the end of a working day. The smell tells my brain that the making is finished. Scent reaches the parts of the brain involved in memory and emotion by a very direct route, which I've written about here, and I am comfortable saying that much. I am not going to tell you it clears energy from a room, because I have no way of knowing that.

 

One practical note. Burning anything produces smoke and fine particulates, and Palo Santo is no exception. Light it for a few seconds, blow the flame out and let it smoulder, then put it out properly once you have what you want. Open a window. If anyone in the house has asthma or a respiratory condition, be thoughtful about it, or use the essential oil in a diffuser instead and skip the smoke entirely.

 

 

Is Palo Santo endangered? The honest answer

 

You have probably seen the posts saying there are only a couple of hundred trees left. They come round every year or so and they are based on a genuine mix up.

 

Two completely unrelated trees are called Palo Santo in Spanish. The one in your incense stick is Bursera graveolens, which grows across the dry tropical forests from Mexico down through Ecuador and Peru. The IUCN Red List currently assesses it as Least Concern with a stable population, and it is not listed on CITES.

 

The other one is Bulnesia sarmientoi, a dense hardwood from the Gran Chaco region of Argentina, Bolivia and Paraguay. It is a different family, a different range and a different use. It is listed as Endangered, and it is on CITES Appendix II. A viral wave of posts a few years ago attached that listing to the wrong tree, and the claim has been repeating ever since.

 

So the scary version is wrong. But I am not going to hand you the comfortable version either, because "not globally endangered" is not the same as "buy freely and don't think about it."

 

The dry tropical forest this tree grows in is under real pressure, mostly from being cleared for cattle and short cycle crops. Illegal cutting of live trees does happen where demand is high and enforcement is thin. Peru took it seriously enough to list the species domestically as critically endangered back in 2006, banning the cutting of live trees and permitting only the collection of naturally fallen and dead wood.

 

There is a counterintuitive point in here that I think is worth sitting with. Demand is not automatically the villain. When fallen Palo Santo has real value, the forest itself has value to the people who live alongside it, and the competing use for that land is usually pasture. Boycotting is not obviously the kinder answer. Buying carefully might be.

 

 

How to buy Palo Santo well

 

Whether you buy from me or from anyone else, this is what to look for.

 

The country of origin should be stated. Ecuador or Peru. If a seller cannot tell you which country their wood came from, they do not know their own supply chain.

 

Naturally fallen wood only. Look for wording like naturally fallen, dead fall or wild harvested from fallen trees. No live tree should ever be cut for this.

 

It should have been aged. Years on the forest floor, not months in a warehouse.

 

And you can judge a lot with it in your hand. Properly aged Palo Santo is darker, with amber and brown streaks running through the grain. It feels dense and heavier than it looks. It smells strongly before you have lit anything. Pale, light, dry looking wood that smells of very little was cut too young. It will burn fast, smoke thinly and disappoint you, and it is usually a sign the supply chain was in more of a hurry than it should have been.

 

The Solis Holder

 

The Solis Holder is made by hand to hold Palo Santo and sage while they smoulder, with a base that catches the ash rather than letting it find your shelf. It comes with a stick of Palo Santo included, so there is nothing else to buy before you can use it.

 

When that stick runs out, you can buy more on their own. I have Palo Santo arriving shortly and it will be listed separately once it is here, so you can keep the holder going for as long as you want it.

 

It sits alongside The Caia Dish and The Terra Bowl in the Sanctuary collection, all of them made to be left out rather than put away in a cupboard.

 

 

That is the Sanctuary side of things. Candles now, reed diffusers shortly, and cold diffusion for anyone who wants a scent built for their own space.

 

If you have a question about any of it, or you want to know exactly what is in a blend before you buy, message me. I answer these myself and I don't mind the detail at all.
