Frequently Asked Questions
Basic Fragrance FAQs
What are fragrance oils? Fragrance oils are specially formulated scent blends used to add fragrance to products like candles, soaps, wax melts, room sprays, diffusers, perfumes, and bath and body products. They are created using a combination of aromatic ingredients designed to provide strong scent performance and stability across different applications.
Learn More About Fragrance OilsFragrance oils are generally considered safe when used properly and within recommended usage guidelines. Many fragrance oils are formulated to comply with IFRA standards, which help establish safe usage levels for different product types. Makers often look for fragrance oils that are phthalate free, paraben free, and free from other ingredients of concern when creating cleaner formulated products.
IFRA compliant means a fragrance oil follows safety standards established by the International Fragrance Association (IFRA). These standards help determine the maximum safe usage rate of a fragrance oil in specific product categories such as candles, soaps, lotions, perfumes, and room sprays.
Phthalate free fragrance oils are formulated without phthalates. Many candle makers and personal care brands prefer phthalate free fragrance oils to meet consumer demand for more transparent formulations.
Fragrance oils are professionally formulated scent blends designed for performance, consistency, and versatility across many product applications. Essential oils are extracted from plants and other botanicals through methods such as steam distillation or cold pressing. Fragrance oils typically offer a wider variety of scent profiles and stronger scent stability compared to essential oils.
Most fragrance oils have a shelf life of approximately 1 to 2 years when stored properly, though this can vary depending on the fragrance composition and storage conditions. Over time, fragrance oils may weaken, discolor, or change slightly in aroma, but they will never grow mold or bacteria as long as you keep them free of water. Fragrance oils should be stored in tightly sealed containers away from direct sunlight, heat, and moisture. Proper storage helps maintain scent quality, stability, and shelf life.
Candle Fragrance FAQs
Fragranced candles are one of the most popular ways to create a warm, inviting atmosphere while filling a space with long-lasting scent. From fresh and clean fragrances to rich gourmand, floral, woody, and luxury-inspired blends, scented candles help enhance mood, elevate home décor, and create memorable sensory experiences. Whether handcrafted for personal use or developed for growing candle brands, high-quality fragrance oils play an essential role in achieving strong hot throw, balanced scent performance, and a premium candle experience consumers love.
Learn More About CandlesYes. Fragrance oils are one of the most common scenting ingredients used in candle making. Candle-safe fragrance oils are specifically formulated to perform well in wax and provide strong cold throw and hot throw performance when used at the proper fragrance load.
The amount of fragrance oil used in candles depends on the wax type and manufacturer recommendations. We recommend candle makers use fragrance loads between 6% and 10%, though some waxes may perform better at lower or higher percentages. Always test your formulation for scent throw, wick performance, and safety.
Many candle makers prefer fragrance oils because they generally provide stronger scent throw, better stability in wax, and a larger variety of fragrance options. Essential oils can be more delicate and may not always perform as strongly in candles, especially at higher temperatures.
Cold throw refers to how strong a candle smells before it is lit, while hot throw describes the fragrance strength when the candle is burning. Both are important indicators of candle fragrance performance and can vary depending on wax type, fragrance load, curing time, and wick selection.
Weak scent throw can happen for several reasons, including incorrect fragrance load, incompatible wax, poor wick selection, inadequate cure time, overheating the fragrance during mixing, or using a fragrance not optimized for candle applications.

Soap Fragrance FAQs
Fragrance oils play an important role in creating beautifully scented cold process soaps, hot process soaps, and melt and pour soap products. From fresh and clean scents to rich gourmand, fruity, floral, and spa-inspired fragrances, scented soaps help transform everyday routines into elevated sensory experiences. Carefully formulated fragrance oils can help support better performance in cold process, hot process, and melt and pour soap applications while allowing makers to create products customers love to use every day.
Learn More About SoapThe best fragrance oils for soap making are specifically formulated and tested for use in cold process soap, hot process soap, melt and pour soap, and other bath and body applications. High-quality fragrance oils should provide strong scent retention, minimal discoloration, and stable performance throughout the curing process.
The amount of fragrance oil used in soap depends on the specific fragrance, soap type, and IFRA usage guidelines. Most soap makers use fragrance loads between 3% and 6% of total oil weight, but always refer to the fragrance’s IFRA certificate and recommended usage rates for safe formulation.
Soap fragrance fading can happen for several reasons, including low fragrance load, improper curing conditions, overheating, or using fragrances not designed for soap making. Some fragrance notes naturally fade faster than others, especially citrus and delicate floral scents.
Certain fragrance oils can cause soap batter to thicken or “accelerate” during cold process soap making. Ingredients such as florals, spices, vanillas, and some essential oil blends are known to speed up trace. Working at lower temperatures and hand stirring can help slow acceleration.
Discoloration in soap is often caused by vanillin content in fragrance oils. Fragrances containing vanilla notes may turn soap tan, brown, or deep chocolate shades over time. Reviewing vanillin percentages before formulating can help makers plan colors and designs more effectively.
