    Goats milk

    Hello Goatgirl, Usually milk and such additives are added in a rebatching step to avoid overheating and other problems that usually emerge from sugars and proteins found in milk. If you wish to try adding the milk from the beginning you can approach it in one of two ways: - Cool the milk in a...

    Almond oil substitute

    Hello Cathy, Sweet almond oil is an oleic oil (the main fatty acid is oleic acid). So you can replace it with an oleic oil such as olive oil, avocado oil and rice bran oil (there are more examples, but it will all come down to your clients preferences or to what is available in your region)...

    Lather and longevity

    Hello TinLee Coconut oil and palm kernel oil are both oils rich in in Lauric acid, so you can replace one with another it is just a matter of price. I suggest you make the following recipe: - Shea Butter = 15 - Cocoa Butter = 20 - Coconut Oil = 43 - Avocado Oil = 17 - Stearic Acid = 5 You...

    Early Tracing

    Hello Bloodrock, it seems to me that the culprit is the high temperature. You could try working at lower temperatures ideally at 35 to 40 degrees Celsius. I would recommend that you mix your oils, fats and butters and melt and mix them, then leave them 48 hours to cool down. before making your...

    hard shaving soap

    Usually you shouldn't need a preservative, but if you are using tap water it is better if you add a chelating agent to avoid DOS.

    hard shaving soap

    Hello Tony, Without the exact recipe it is a bit difficult to help you with this problem, but I took the liberty of trying a recipe with the following ratio: - Castor Oil - 4% - Mango Butter - 32% - Shea Butter - 32% - Kokum Butter - 32% I noticed that those butters are rich in stearic acid and...

    Longevity

    Once I tried to compare soaps made from refined and deodorized shea butter and unrefined or crude shea butter. The latter smelled like I was saponifying a dead rat and I was unable to continue working with it, while the refined shea butter soap smelled as you said "a pure clean soap scent". For...

    Longevity

    Glycerin for the first few percentages gives a softer and more soluble soap, but for percentages around 6% the soap actually hardens more and is less likely to dissolve (of course all percentages are for a final product after processing and curing). That being said, note that cold processed...

    Longevity

    The hardness, longevity and other characteristics in all online calculators (to the best of my knowledge) are overly simplified calculations. In my experience they are mostly adapted to multi-oil soaps. They become obsolete with single-oil soaps and specialty soaps. The reason behind this is...

    Lactic Acid

    Is it possible to add Lactic acid to the Additives section, alongside with the necessary calculations for Lye quantities in order to transform it into Sodium Lactate (in a similar fashion to citric acid).

    Glycerine soap vs CP

    I am aware that the oxidized SLES70 gives a brownish yellow color, so if you have changed suppliers recently check with them. sometimes the sorbitol will give a brown color if heated at high temperatures, so check the equipment that you are using they may need recalibration.

    CP donut trouble

    you should try decreasing the lye concentration for the topping (if you use a lye concentration of 33.33% for the CP donut, try a lye concentration of 25% for the topping). the additional water will help it stick without crumbling. if this method fails, try a different oil recipe for the...

    Savon chocolat

    En théorie c’est faisable. Mais la grande quantité de sucre présente dans une tablette de chocolat va accélérer la réaction de saponification du coup il faudra passer en procédé à chaud qui pourra causer des réactions nocives vis-à-vis les odeurs. En touts cas, si tu fera l’expérience j’aimerai...
