Can I Use Crayons to Color My Soap?

Crayons are composed of wax and unpredictable pigments that don’t stand up well in soap making, so instead opt for natural colorants such as herbs and roots commonly found in other recipes.

If you prefer more vibrant hues, non bleeding colorants like oxides or ultramarines may provide the desired hues. Before adding them to your soap base, be sure to mix the pigment in water or glycerin first to allow proper dispersion.

Most soap makers utilize some sort of colorant to tint their soaps. Color options range from FD and C dyes made in laboratories synthetically to natural pigments and micas; all have their own advantages and disadvantages. While lab dyes provide more colors, using them in large quantities could potentially irritate skin; hence they should only be used sparingly; ideal choices would include hand soaps or body washes.

Some soapmakers prefer organic or natural colorants over chemical ones. Such colorants come from roots, herbs and purified clays like kaolin clay or rose clay. While natural colorants provide an appealing natural alternative, their vibrant hues may fade over time without proper dispersion using glycerin or alcohol solutions.

Mica is an organic substance found in granite and other rocks, and makes an ideal soap coloring agent. Available in numerous shades, mica offers an easy alternative to the more volatile FD/C dyes. Although easy to work with, mica may become unstable after prolonged usage in soap production – so always test before creating large batches.

Natural herbs for soap coloring is another popular approach, as many of these offer skin nourishing properties and can assist with various skin issues. Some popular choices are paprika, indigo powder and turmeric as potential choices.

Iron oxide is another natural colorant and should be used with caution when cold process soaping as it may irritate skin. However, in melt and pour soaping it can provide an eco-friendly alternative to chemical dyes.

Crayons can be made into fun and creative soap crayons for kids. Start with clear or white melt and pour soap base, melt it, add food coloring drops to it and separate each bowl as soon as the colors have been mixed to avoid mixing together or merging into each other. After coloring is complete, let it cool before molding it into whatever shape or form desired.


Glycerin is an amazing by-product of soap making that’s safe and beneficial to skin health, not to mention being an amazing moisturizer. Making homemade glycerin soap at home is easy and affordable – you can add fragrances or colors for a customized finished product! For this project you will need: stainless steel pan; glycerin; fragrance/colorant/fragrance of choice (I like Everclear); spoon and rubbing alcohol (or an alcohol alternative like Everclear).

Many soap manufacturers use melted crayons to color their products, yet experts do not advise this approach as the resulting soap could contain unknown pigments, wax and extra paraffin from its petroleum production process. Instead, DIY Naturals advises using more natural coloring options such as powdered mica minerals, oxide colors, activated charcoal cosmetic clays or mineral shimmer for coloring purposes.

Start by heating up your glycerin soap base slowly in a stainless steel pan over low heat and adding desired dyes or colored soap beads or chunks, including crushed dried herbs or flowers that could oxidize quickly – this process causes color fading or even disappearance after just days! When adding crushed herbs or flowers be mindful of how fast their color fades as the oxidation process may cause it.

Soap color should always be thoroughly mixed prior to being added into a melted soap base, in order to ensure there are no clumps of dye left behind in the final product. When coloring with powdered mica or oxides, mixing these separately beforehand in a small bowl may help with this step – simply slowly incorporate these hues as the melted soap base cools.

Keep in mind that when using food coloring or melted crayons to tint your soap, it’s essential that you work in small increments at a time – too much color could cause runny or mushy results! For the lightest shade start out by beginning with that and gradually add more as necessary.

Once your glycerin soaps have set and solidified, remove them from their molds and let them air-dry completely before storing or gifting them. Melt and pour soaps act as natural humectants by drawing moisture out of the air; left sitting out too long they may start sweating, producing small beads of moisture on its surface that make the bar slimy when in use.

Soap Base

Colored soap provides sensory stimulation to its user. Kids love playing in the tub with colored soap, drawing patterns on sinks or shower tiles with it and even creating designs on countertops or tiles with it! Many soapmakers utilize natural colorants that offer subtle natural tones while some even provide additional benefits such as vitamin C, alpha hydroxy acids or exfoliation benefits – these natural colorants can be purchased from soapmaking suppliers like Mountain Rose Herbs or DIY Natural.

When using natural ingredients to color your soap, be sure to read and follow any label instructions to make sure they are compatible with glycerin. Any colorants derived from petroleum sources or known to cause cancer should also be avoided. It is a good idea to conduct a small test batch first in order to see how it performs before creating large-scale batches.

To add a creative touch to your soap creations, try mixing mica or cosmetic-grade pigments into its base. They are easy to work with and give a wide range of colors for you to select from.

Some colorants may be oil-soluble, and should be dispersed in glycerin or alcohol before adding them to soap. You can also add pearl powder or other glitter-type colorants for some sparkle!

Crayon gratings should be handled carefully to avoid staining your soap. A good practice would be to pass crayon over a grater 10 times on a paper towel before funneling these gratings into your soap base. However, be wary not to over-add crayon gratings as this could decrease its lathering quality and impair lather quality in the glycerin in your product.

If you plan on adding food coloring to your soap, it is wise to divide the soap evenly among bowls of equal number of colors in order to prevent their bleeding into each other as they mix. When mixing colors, start with lightest shade first and wipe fork after every stroke to prevent smudging the next hue.


Colored crayons can be an effective way to encourage children to draw, and are an ideal alternative to markers with sharp tips that could cause injuries when used by young children. Plus, crayons do not require sharpening and are non-toxic!

Crayons are composed of paraffin wax that has been melted, mixed with powdered pigments and sometimes clay to thicken it, then pumped into molds where they cool and harden before being wrapped, labeled, sorted and boxed before shipping all over the world for use by kids at school and at home. If you want more insight into their production process, Crayola has an informative video on YouTube showing exactly how these wonderful toys come to life!

When creating soap crayons, it’s essential that the soap be tightly packed in each mold in order to avoid cracking or crumbling when taken from its mold. I prefer miniature ice cube molds for this task; this makes ensuring each crayon has the ideal shape.

As part of your soap base preparation, it is also crucial that the grated soap becomes thoroughly mixed with its colorant. I found that adding around 1/8 teaspoon (roughly 10 passes over a standard dollar store hand-held grater) per ounce gave an optimal level of coloring.

Finally, it’s essential to work quickly and keep your hands clean as you add each color. This is particularly important when working with food coloring that can stain fingers and hands easily if not carefully used. I find it helpful to work near a sink or in the garden so my hands can easily be washed after adding each new hue.

This project is quick, simple, and fun – ideal for children of all ages! This would make a wonderful addition to an art-themed birthday party or as Halloween treats (just be sure to label them so no one eats them!). They also make wonderful bathtime companions!
