Fragrance Formulator

Entering Your Wax Type and Fragrance Load

Start by selecting your wax type. Different waxes hold fragrance at different levels, so knowing the recommended load helps maintain performance and safety. Input your total batch weight, select your preferred fragrance load percentage, and the formulator will calculate exact measurements by weight. This avoids guesswork and supports safer, more effective results.

Adjusting for Flash Points and Pour Temps

Each fragrance oil includes a flash point, the temperature at which it begins to evaporate. Pouring too hot can cause scent loss. The formulator allows you to view flash point data for each oil, helping you adjust your pour temperature accordingly. This step matters when working with complex blends or subtle scent notes.

How Much Fragrance Oil to Use

Most waxes perform well with fragrance loads between 6% and 10%, depending on the formula and oil strength. Softer waxes like soy blends may need more to get a solid hot throw, while harder waxes might cap out sooner. The fragrance formulator shows you the exact amount in grams or ounces based on your load, making test batches easy to scale.

Blending Scents Like a Pro

Start simple. Try a 2:1:1 ratio when testing two complementary scents and a grounding base. Many successful blends evolve by shifting those ratios slightly. Think in thirds, quarters, or percentages, not drops. The tool allows you to enter your ratios and see them converted instantly into weights for consistent duplication.

Tips for Testing Throw

Cold throw can show up quickly, but hot throw takes time. Cure your candles for at least 48–72 hours before lighting. Take notes on scent strength during the burn, and test in a closed room with minimal airflow. If throw feels weak, try increasing your fragrance load slightly, adjusting your wick, or reformulating with stronger base notes.

From Hobby to Signature Line

Whether you're blending a scent for fun or building a signature line, the fragrance formulator keeps your process clean and trackable. Each formula can be saved and re-used, making it easier to scale up once you're happy with the throw and balance. This tool supports scent development for both experimentation and consistency across batches.

Pairing Tools & Supplies

To get the most out of your blends, use a precise digital scale, pipettes for small adjustments, and a clean glass container for pre-mixing. Our candle fragrance formula tool works best alongside waxes that are already tested for performance, so choose oils labeled for candle use and reference IFRA guidelines where needed.

How much fragrance oil should I use in candles?

It depends on your wax and scent goal. A typical range is 6%-10% by weight. Some waxes max out at lower percentages, while others allow more, but going over the recommended load can affect burn performance and safety.

Can I mix multiple fragrance oils together?

Yes. Blending allows you to create custom candle scents tailored to your vision. Just make sure the combined load stays within your wax’s safe range. Testing each new blend in a small batch first helps avoid waste.

What is a flash point and why does it matter?

A flash point is the temperature at which a fragrance oil may begin to evaporate or ignite. In candle making, it's used as a guideline for when to add your oil during the wax melt. Pouring at lower temps, under the oil’s flash point, helps preserve scent strength during the burn.
