What is the best candle wax?

There is not really a 'best' wax overall, as all waxes have their own strengths and weaknesses, but there are some waxes that will work better than others in a particular application.

Waxes are generally split into two categories: Pillar/melt waxes and Container waxes and can be either vegetable based or mineral wax based.

Pillar blends cool very hard and are used for making free-standing candles that do not require a container or wax tarts/melts.  

Container waxes - as the name suggests - are softer waxes designed for use in a container of some form; be it a metal tin, glass jar, coconut shell or anything else you care to fill :)

In terms of mineral vs. vegetable wax, this is a debate that is only really had amongst candle makers as the majority of customers are apathetic to the wax used.  Customers generally want a candle that looks and smells nice; it is us candle makers that tend to get hung up on the exact details of the wax, either as a USP or because we think consumers make buying decisions based on wax.

As a general rule, paraffin (mineral) waxes make stronger scented candles.  This is why most luxury brands still use paraffin wax, or blends that contain a lot of paraffin wax.  They have not missed a 'natural' gap in the market; they choose to use paraffin wax because it makes great smelling candles.  Whilst paraffin wax is often associated with smoke and soot, a well made paraffin candle should not produce much soot at all.  

Vegetable waxes, such as our EcoSystem blend, or soy, rapeseed and coconut waxes are relatively new compared to paraffin waxes, but are growing in popularity as they have good Eco credentials which can offer some marketing benefit.  They also create melt-pools that cover the entire surface of the candle quite quickly, whereas paraffin candles tend to burn down with a more concave profile (with hang-up).

Whilst predominantly used by skincare/spa brands, vegetable waxes are also used by other brand owners wishing to create a more 'natural' candle.  These waxes are very soft and have a beautiful texture, but generally generate less scent throw than paraffin equivalents.  They can also be more difficult to work with as the waxes are much denser and do not transfer heat too well.

In our contract candle manufacturing business, we rarely use 100% paraffin or 100% vegetable blends. The majority of our candles are made using 70-80% paraffin wax and 20-30% vegetable wax.  This tends to give the candle the sensory benefits of paraffin.  Another popular blend is the opposite; i.e. 70-80% vegetable and 20-30% paraffin.  This results in a more vegetable-like finish, but the added paraffin reduces the triglyceride content sufficiently to prevent polymorphism (frosting and pitting). 

In summary, many waxes are suitable as candle bases and each have their own strengths and weaknesses.  Paraffin wax is the most widely used and is easy to work with.  Vegetable waxes offer a more natural alternative, but are slightly harder to work with.  Both can produce beautiful clean-burning candles if correctly made.  If you are serious about candle making and have the time and money, it is worth experimenting with wax blending.  There is extremely limited support in this area, as no candle maker will ever disclose the make-up of their wax blends, so trial and error tend to be the only way.

Candle Shack Fragrances

Are your fragrances safe, vegan and paraben free?

All of our fragrance oils are vegan friendly, cruelty free and paraben free. 

Please refer to the SDS for each fragrance for information on phthalates.

Please refer to the PDF files at the bottom of every fragrance page for the SDS, IFRA and Allergen Declarations.

There are also template labels available for candles, diffusers and melts.  These templates show all of the information you must have on your product.


Are your fragrances safe for pets?

Our fragrances have been created in line with IFRA standards, which are there to ensure the safe use of fragrances ingredients, however; IFRA’s standards are aimed at humans, and they do not produce standards regarding the safety of suitability of fragrance ingredients in relation to pets. We recommend contacting a veterinarian with any concerns or for advice.


Some of our fragrances do carry this hazard in their raw form. Once diluted, this hazard is no longer applicable. If ever in doubt, check the 8% or 10% SDS that is available via the website for hazards applicable to your candles or wax melts. In any case, we recommend using the appropriate PPE when handling ALL fragrances.


What is the difference between fragrance oils and essential oils?

Essential oils are made from natural ingredients using processes such as steam distillation and solvent extraction. The intention is to capture the "essence" of the plants.

Fragrance oils are made from synthetic fragrance molecules. Although they are man-made, many synthetic molecules are identical to molecules found in nature, but many more are designed by fragrance chemists to give specific aromas that can be used to produce unique and novel fragrance oils.

Both essential oils and fragrance oils are blends of many different types of fragrance molecules.

What are nature-derived fragrances?

Nature-derived fragrances are complex compounds, derived from natural aromatics extracted from nature including trees, plants, and flowers, that also include a small amount of replicated natural accords harnessed without harming the environment.

These natural accords are processed from natural sources by physical or biotechnical procedures to harness the ingredients and consist of materials that can be physically isolated from plants through distillation expression and extraction.

Nature-derived materials can be extracted from plants - one oil can have several different isolates from several plants.

How much fragrance should I use?

Essential oils can have different viscosity than fragrance oils as they are made from natural ingredients, while fragrance oils mainly contain synthetic components. As natural oils tend to be more viscous, we recommend using them at a lower ratio.

If you are looking to make a candle using essential oils, we advise testing your candles with 6-8% oil, while 15% would be a good starting point for your diffusers, subject to any IFRA or CLP restrictions.

If you prefer fragrance oils, you can start testing your candles with 8-10% but you can add up to 14% in some plant waxes, and our recommended diffuser ratio is 15-20% subject to any IFRA or CLP restrictions.

Please always check the IFRA conformity certificate on the product page for each essential oil or fragrance oil, as all oils have maximum permitted percentages for candles, diffusers and rom sprays under IFRA/CLP guidelines.

For concentrated fragrance oils, you can use a lower percentage of oil and still get excellent cold and hot throw. Depending on your wax, our recommended ratio is 3-5% for candles, whilst with diffusers we would advise you to start testing with 8-10%.

What wick should I use with my fragrance?

The choice of wick will depend on which wax is being used. LX or TG wicks work well with mineral waxes. Stabilo, CL, V, TB, ECO or PGS wicks can be used with mineral or vegetable blends, while VRL wicks are suited to blends containing a high percentage of plant wax.

Overwicking can cause larger flames which can then form larger melt pools and generate more soot. Overwicking is the term used to describe the use of a larger wick than necessary for a particular candle.


What is CLP?

CLP is an EU and UK regulation which requires hazardous chemicals to be classified, labelled and packaged accordingly to ensure a high level of protection for consumers, workers and the environment.

Is CLP LABEL DESIGN tool free?

Yes! We know how difficult and time-consuming adhering to CLP regulations can be. As such, we designed this tool to help you quickly get an accurate label at the click of a few buttons.

Can I access CLP DESIGN TOOL on mobile?

It has been specifically designed for desktop devices and is optimised for Chrome and Microsoft Edge Internet browsers.

What fragrance oils are included?

All Candle Shack fragrance and natural oils have been included.

What type of products can I generate CLP labels for?

This tool can generate labels for Candles (10%), Candles (8%), Candles (6%), Diffusers (15% in Augeo), Diffusers (20% in Augeo), and Room Sprays (5% in non-hazardous base).

What if some of the label templates are missing?

If you can't find the CLP label you are looking for, please check the fragrance description and Safety Data Sheets, as it may be the case that there is no CLP requirement at the chosen scent content or the fragrance can't be used above a certain percentage.

Can this tool be used for custom bases, scent contents or sizes?

At the moment our CLP Design Tool can only be used to generate the labels mentioned above, however, we do offer services for custom SDS and CLP labels using Candle Shack oils or custom essential oil blends.

Can this tool generate CLP labels in other languages?

You can design your CLP labels in 24 different languages: English, Bulgarian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Irish, Italian, Latvian, Lithuanian, Maltese, Norwegian, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish and Swedish.

Will 60mm labels fit on all Candle Shack containers?

Yes, they will. You can use this size of label for all Candle Shack containers apart from 9cl.

What mass/volume information should I include in my CLP label?

You should always include NET weight. This is the weight of wax and fragrance, excluding the weight of the container.

Can I combine CLP label with safety information using this tool?

Yes, you can! If you choose to do so, pictograms on the left are mandatory. Pictograms on the right-optional, and can be chosen if they are relevant to the product. Please select the maximum of 5 safety pictograms. 

Once I finished designing my labels where can I print them?

We recommend using PRINTED.COM. They offer great prices and fast delivery service.
