Please note: Since we no longer offer cold process soap supplies, we offer this free information to you, but cannot offer any type of technical assistance pertaining to any form of cold or hot process soap making. Thank you!
This is where you can let your imagination go wild! Soap additives are all optional. All of the following ingredients should be added at trace in bar soaps, and after dilution in liquid soaps for optimal results.
The addition of 1 tsp. preservative per pound of soap paste
(Preservative Suggestions: Vitamin E Oil or Rosemary Extract)
The preservative is to be added to the soap mixture once it is already diluted. This will prevent the nutritive value of the ingredients from being destroyed. To superfat liquid soap (using the recipes that we have provided), add 5 Tablespoons of sulfonated castor oil to the diluted liquid soap.
The only superfatting agent that is suitable for liquid soaps is sulfonated castor oil because it is water soluble. All of the other oils tend to cloud the liquid soap because of their free fatty acid content. When making cold process bar soap, you may wish to superfat your soap by adding the following ingredients during trace in small amounts (these amounts you will have to decide): hemp oil, hazelnut oil, wheat germ oil, to name a few.
Here is a list of natural colorants that you may desire to use to color your soap products, however, you may also desire to use a water-soluble soap dye. Natural colorants include: annatto seed, beetroot powder, beta-carotene, black-eyed susan, calendula blossom, chlorophyll, cocoa, comfrey, goldenrod, goldenseal, licorice root, madder root, paprika, rose hips, turmeric, wheat germ, yarrow.
Here is a list of exfoliants that you can add to your soap products: oatmeal, poppy seeds, alfalfa meal, corn meal, millet seeds, coconut flakes, coffee grounds
When making soap products, you may use essential oils or fragrance oils. The amount of fragrance you will use is your decision, but we use 1% fragrance in the soap mixtures. Once again, you will add these at trace in soap bars, and after dilution in liquid soaps.
Here is a list of nutrients that you may desire to add to your soap products: sweet almond oil, aloe vera, apricot kernel oil, beeswax, calendula oil, castor oil, cocoa butter, evening primrose oil, hemp seed oil, honey, lanolin, milk, neem oil, jojoba, shea butter, wheat germ oil, vitamin E oil.
Shampoo enhancers: glycerin ( 1-2 oz. added to a pound of shampoo) is an excellent moisturizer and conditioner. It also allows for shiny, luxurious hair. Castor oil added to shampoo is a wonderful cleanser, moisturizer, and conditioner. Essential oils of lavender, and rosemary condition hair and stimulate hair growth. Extra effects can be accomplished by adding a small amount of mica pigment to your transparent products to create a pearlized look.
