Colourant and fragrance ❤

How does colourant, scented candles created in our lives????
Candles are colored either throughout or they sometimes consist of a white body that is covered with a colored layer of paraffine wax. According to the material from which candles are made (stearine, paraffine, or ozokerite), the process of coloring varies. Scents can also be added during the manufacturing process to make scented, colored candles.
Although candle color is the second-most important factor (after fragrance) for influencing consumer purchasing decisions, color and fragrance are closely linked. In fact, research has shown that consumers expect the color of a scented candle to mirror their psychological perception of the fragrance. A cinnamon-scented candle, for example, is expected to fall somewhere in the red-bronze palette, while "mountain breeze" draws expectations of a candle in the pale blue or green shades.

                            
Wax colorant
Colorants are added to the uncolored wax to give the candle color. Candle dyes are engineered to burn alongside the wax and not interfere with the natural burning properties of the candle. Industrial manufacturers often use dyes in either liquid or powder formulations, since they give more control over the final color of large batches of candles. However, artisan candle-makers often use colored blocks of highly colored wax that are easier to mix with the smaller amounts of candle wax used. Some candle wax blends require more dye than others to obtain the same color intensity. For this reason, the final color of a candle will depend on the amount of colorant and the blend of candle wax used.



Fragrance
There are many substances that can be added to the colored wax to give it scent. The most common substances used to create scented colored candles are either chemical scents or fragrance oils and even aromatherapy-grade oils added to create highly scented candles.



What Is the Dye in a Colored Candle Made of?

Candle dye may come in multiple forms, but what is it made of? Most synthetic dyes today are aniline, and since they aren't rated by the FDA, manufacturers don't have to release their list of ingredients. Chemical ingredients are typically used to create the colors. Some manufacturers use natural or even organic ingredients instead. Herbs, spices and flowers can all be used to create dyes.

There are two types of dyes used to make candles: liquid and powder. Most candle dye companies also sell dye in the form of chips. Liquid and powder dyes are about the same in the quality of color they produce. Dye chips, on the other hand, may look slightly more diluted. Dye chips are essentially tiny pieces of wax containing a high amount of color, but because there is wax in this form of dye, the color isn't quite as effective.



Dyes vs. Pigments

Specially-formulated pigments and dyes are used to color candles. Dyes have different properties from pigments, and are used to create different effects. In general, pigments are used to coat the outside of a candle with color, while dyes are used to color the candle throughout. 

Dyes

Available in both liquid and powder form, dyes give a candle its translucent color. Dyes also provide the candle maker with a large degree of control over a color's shade. Because dyes are easily combustible, they will not clog a wick, and generally have a minimal effect on the burn performance of a candle with color.

Pigments

Pigments are microscopic, suspended color particles that create a solid wall of color, similar to paint. They do not dissolve, migrate or "bleed," and thus are not as susceptible to color fade as dyes.  Pigments usually do not burn well, and the color particles will clog a wick if burned.  This makes them unsuitable for a candle that is colored throughout and meant to be burned, but useful for coating the outside of the candle.



When using dyes, be careful when you handle them. Because most dyes are made from synthetic products, they can stain skin, cloth and other materials. Some people have allergic reactions to some of the ingredients in the dye. Wearing protective clothing like gloves can keep you safe and makes cleanup easy.When using candle dyes, also be aware that the makeup of your candle will change slightly. This is most important to keep in mind if you are making candles with a layered effect.

                                 



Natural Candles - Coloring your Candles with Herbs and Spices

Spices


  • Adding spices to the hot wax will not only produce different colors but will also create aromatherapy candles. In this instance, the spice will act more like a pigment than a dye, specifically if you use ground spices in the form of powders. Turmeric and sassafras create orange colors, saffron produces blue and purple colors and saffron will produce yellow colors.

Herbs


  • While many dyes are produced synthetically, they were originally made using herbs. The herbs are heated in oil to extract the color or can be added to the hot wax, though you will need to strain the plant parts out before dipping the candles. Herbs that can be used as dyes include wild celery for a light yellow color, sunflower seeds for deep purple, ground lichen for orange, elder for blue colors, and dandelions and St. Johns Wort for red colors.
