Store wax cool, dry and out of sunlight; store fragrance oil tightly closed, in the dark, at room temperature and as its safety data sheet directs; and store finished candles upright, lidded, away from heat and light, using the oldest first. Shelf lives are product figures: the Golden Brands GW 464 instructions give that wax a minimum of 3 years stored properly, while CandleScience says most fragrance oils last about one year and a UK supplier cites 24 months for raw oils. Heat is the main enemy of finished stock, because container waxes melt at low temperatures. This page sets out what each supplier says for wax, oil, dye and finished candles, and how to rotate stock.

At a glance

Item	Keep	Keep away from	Shelf life, as published
Soy container wax (GW 464)	Cool, dry location	Direct heat, sunlight and moisture	"minimum shelf life of 3 years" when stored as instructed [1]
Beeswax	Cool, dry place, rendered and clean, in blocks	Pesticides (never in the same room)	"Wax can be stored for very long periods of time" [2]
Fragrance oil (CandleScience)	65 to 85°F (18.3 to 29.4°C), dark, in opaque or amber bottles	Direct sunlight; refrigeration	"Most fragrance oils last about one year" [3]
Fragrance oil (Candle Shack, UK)	Cool, dark, dry; not in transparent bottles	Humidity and fluctuating temperatures	"Most raw, undiluted fragrance oils have a manufacturers shelf life of 24 months" [4]
Fragrance oil (any)	As section 7 of its SDS says	As section 7 says	As its supplier says
Finished candles	Upright, lidded, at steady room temperature	Heat, sun, vehicles in summer	Set by your own testing

Wax

The GW 464 instructions explain why heat matters for a soy container wax: "Due to its low melt point it is important to keep flakes stored in a cool dry location away from direct heat, sunlight and moisture" [1]. GW 464 melts at 113 to 119°F [1], a temperature a closed car, an attic or a shelf by a sunny window can reach. Flakes that soften and set again into a block are harder to weigh out, and wax that has picked up moisture or dust is a different input to the one you tested.

Keep the original bag or carton with its lot number, sealed between uses. If you decant into bins, label each bin with the product name, lot number and the date you opened it, so a batch record can still name the lot.

For beeswax, the UN Food and Agriculture Organization advises storing it rendered and clean, in cool, dry places, and never in a room with any pesticide [2]. FAO notes that wax "will slowly crystallize over time and as a consequence become harder," and that this is reversible [2]. Clean wax in large blocks is not attacked by wax moths, while unrendered comb is [2].

Fragrance oil

Two suppliers' figures, and a disagreement on shelf life:

CandleScience: most fragrance oils last about one year. Store them in a dark area away from direct sunlight, ideally between 65 and 85°F (18.3 and 29.4°C). Do not refrigerate, because "Fragrance oils can crystallize at lower temperatures." Opaque or amber bottles help protect against light [3].
Candle Shack (UK): most raw, undiluted fragrance oils have a manufacturer's shelf life of 24 months. Keep bottles in a cool, dark, dry space away from sunlight, heat and humidity, avoid fluctuating temperatures, and do not store fragrance in transparent bottles [4].

The two sources agree on how to store oil and differ on how long it lasts by a factor of two. Each is speaking for its own oils. Follow the supplier of the oil in your hand, and if it gives no figure, ask. Whatever the figure, write the date you received each bottle on it. Store oil where children and pets cannot reach it: Poison Control advises keeping essential oils locked up, out of their sight and reach. If anyone swallows oil, call Poison Control at 1-800-222-1222, which it says is free, confidential and available 24 hours a day [10].

What the SDS adds

Section 7 of each oil's safety data sheet gives its handling and storage conditions, and they are the supplier's specific instructions for that oil. AFI-USA's SDS for its fragrance oil F67142, for example, says to keep it away from heat, sparks, open flames and hot surfaces, to store it in a well-ventilated place, keep the container tightly closed and keep it cool [5]. An oil with a low flash point may carry a flammable liquid classification and stricter storage advice. Reading a fragrance oil safety data sheet goes through the sheet, and what a fragrance oil's flash point means explains how flash point affects storage and shipping.

In short, fire codes and OSHA class stored oil by its flash point, with lines at 140°F (60°C) and 200°F (93°C) that mirror the shipping classes; the full storage class table, with the OSHA container and cabinet limits that apply once you have employees, is on making more candles. How much flammable or combustible liquid you may keep in a home or small workshop is a local fire code question. Setting up a place to make candles explains who to ask.

Signs an oil has aged

CandleScience names two: "A noticeable color change can indicate that fragrance oil components have oxidized or degraded," and an oil that smells "different than you remember, rancid, or sour" has likely gone bad [3]. Keep a small retained sample of each lot when it arrives, sealed and in the dark, so you have something to compare against. An oil that has changed is a new variable; make a test candle before you pour a batch with it.

Dye and wicks

Liquid dye loses color with heat and light. Voyageur Soap & Candle warns that higher temperatures or prolonged heat can degrade its dyes [6]. Keep dye bottles closed, out of sun and away from the melting area. CandleScience packaged its dye blocks in foil bags to stop color bleeding onto other surfaces [7]; keep blocks in their packaging.

Store pretabbed wicks flat and dry in their packs, labeled with series, size and lot. A bent or kinked wick is harder to center.

Finished candles

Heat

Container candles are made of wax that melts not far above room temperature, so a hot room, a sunny shelf or a vehicle in summer can soften or melt them. CandleScience's oven test shows how sensitive a soft candle can be: laid on their sides at 113°F (45°C) for 24 hours, coconut apricot candles with up to 13 percent fragrance kept their shape, and some at 15 percent melted out of their jars [8]. That test is a good model for checking your own candles against the conditions they may meet in storage or transit, and it is set out step by step on melt point, and why container and pillar wax differ. Packing and carrier choices for warm weather are on shipping candles without breakage or melting.

Position, light and air

Upright. CandleScience recommends "storing your candles upright as much as possible" [8].
Lidded or covered, to keep dust off the surface and scent in the candle.
Out of sunlight and bright light. Dyes fade, and some oils change color: SA Candle Supply says vanillin oxidizes when exposed to air and light, giving yellow to brown tones over time [9]. A lid and a box slow both.
Away from strong smells, such as cleaning products or other scented stock, if the candles are not sealed.

Rotating stock

Finished candles do not carry a published shelf life from any wax maker cited here, so set your own from experience: keep one candle from each batch, check its cold throw and appearance every few months, and note when it is no longer what you want to sell.

Label every tray or case with the batch number and pour date.
Sell or use the oldest batch first.
Keep a retained candle from each batch, in the same conditions as your stock, for checking and for answering a customer complaint.
Check stock on a fixed schedule for sweating, frosting, fading and lost scent, and pull any batch that has changed.
Record what you find with the batch, as set out on records a candle business keeps.

Start with each oil's safety data sheet

The storage instructions that matter most for safety are on each oil's safety data sheet. If you have not read one closely yet, start with reading a fragrance oil safety data sheet.
