How to Make Pine Tar Soap
Pine tar has been used as an ingredient in soaps for centuries. It is known to help with skin conditions like eczema, dandruff, psoriasis and other itchy skin conditions, and has been known to help relieve the itch from insect bites.
What Pine Tar Looks Like
Pine tar is a super thick and gooey pitch that has a smoky, pungent, woodsy and leathery smell. It is often locally available at farm supply stores as a treatment for horses' hooves and through mail order.
Controversy With Creosote
Creosote, a... by-product of burning certain materials, is known to be a carcinogen. Creosote is contained in coal tar and can sometimes be found in pine tar depending on how it is made.
Some soap makers say that as long as they use "creosote free" pine tar, there is no risk and their soaps are safe for sale. Others believe the amount of creosote in veterinary grade pine tar is so minimal that the risk is negligible, that creosote is found in many things we are commonly exposed to, and that the creosote in pine tar is less than what would come from cooking over a fire or barbecue.
Treating Skin Conditions
According to soap and cosmetic labeling regulations, when stating that soaps can treat skin conditions, you are creating a drug, not a cosmetic. This label has more stringent guidelines, testing regulations and laws than classic soaps do.
Kelly Bloom of Bloomworks Natural Soaps discontinued selling it for this reason, as both a finished soap or rebatch base. While she was manufacturing it as a "natural soap," customers were buying it as a treatment. Kelly stopped selling pine tar soap but still makes it as a "get you clean" soap.

Preparations for Pine Tar Soap
Prepare Your Materials Ahead of Time
- Mix at low temperatures. You can try your batch with lye at room temperature and the oils at about 85 degrees.
- Use a lot of water in your recipe. A ratio of 2:1, water to lye, is recommended. Water should equal two times the amount of lye. For this recipe, your water... may calculate at about 2.7 times the amount of lye.
- Adjust your recipe to be slower to trace. Include slow-to-trace oils like lard and olive and remove quick-to-trace oils like castor and palm.
- Be careful with fragrance or essential oils that may speed up trace. Lavender tends to slow down trace.
- Don’t use a stick blender. Whisk it to mix it.
- While you measure out oils, put the can of pine tar in a large bowl of very hot water. This will help make the pine tar a bit more pourable when it comes time to adding it to the soap pot.

Melt Hard Oils and Add Liquid Oils
- While the pine tar is warming up in hot water, measure and begin melting hard oils.
- Once the hard oils have been melted, take the pot off of the heat.
- Add in the liquid oils.
- Now you add the pine tar. It's sticky, so you can measure it right from the can into the soap pot. Note that this only works if you can put a hot soap pot on top of your scale. If you can't, measure the pine tar into a separate disposable container.
- Put your soap pot onto the scale and carefully measure out the correct... amount of pine tar in the heated oils.
- Stir the oils and pine tar very well.

Adding Essential Oils to the Soap Pot
This recipe will come to trace quickly so it is recommended to add the essential oils to the oils before adding the lye. Normally, you would do this at trace to lessen the essential oils' exposure to the lye. However, since the temperatures are low and the mix will thicken quickly, add the essential oils first.
Ounces for Essential Oils
The pine tar has a smoky, pungent scent, so you may wish to compliment it with 2.1 ounces of essential oils, such as the following:
- .7 ounce lavender essential oil... (33%)
- .5 ounce eucalyptus essential oil (24%)
- .5 ounce Siberian fir essential oils (24%)
- .4 ounce tea tree essential oil (19%)

Add the Lye and Whisk Stir
- After mixing the essential oils well into the oils and pine tar, slowly add the lye solution to the pot. Do not use a stick blender; whisk the mixture together.
- After a few stirs with the whisk, the soap mixture will start to turn more opaque and a lighter color. This is your soap beginning to saponify.
- Keep stirring slowly but firmly for several minutes. The soap will thicken up like thick chocolate pudding or cake batter. Identifying a moment of trace is difficult here. What you want to achieve... is absolutely complete and thorough mixing.
- If in doubt, keep stirring some more. Be sure to scrape the sides too. Do not let it get too thick to pour.

Pour the Pine Tar Soap Into the Mold
- Pour the soap mixture into the mold. Use a rubber spatula to get it all out of the pot.
- Be sure to slam the mold firmly on the counter to release any air pockets or bubbles.
- Optionally, you may smooth the top of the soap flat with your spatula or use your spatula to make some waves and swirls in the top of the soap. It gives the final bars a nice handmade look.

Finish and Unmold
After 24-36 hours, you can unmold and cut your soap. Normally, a soap with this much water would take several days to be ready to cut but this batch is firm enough to cut the next day. Most people recommend to let it cure several additional weeks to get it a bit harder.
