FAQ Regarding Soap Additives

FAQ Regarding Soap Additives

Hello everyone, thought I would put together a little something as I get asked these questions a lot and I will use this blog post as a point of reference in future. They are regarding certain ratio's of additives and will list them here

 

Ratio's are based on Percentage of Total Oil weight in your soap recipe

 

 Sugar - Lather & Conditioning Booster

Max 3%. Dissolve in water before adding the lye

Salt - Hardness Max 3%. Dissolve in Water before adding the lye. I find 2% adequate when not using with Sodium Lactate. 
Sodium Lactate - Hardness, lather & conditioning booster + Easier unmoulding Max 5%. Start with 1-2% first. I find 2% is the sweet spot if not using with salt. Adding more may result in a crumbly bar. Add to your cooled lye water below 50C / 122F
Salt + Sodium Lactate (My go-to Combo) Adding 1.2% of each is the sweet spot if using both
Clays Max 3%. If you're using one clay color, can add either before adding the lye, mix in well with oils. You can also add after emulsion or light trace and whisk them in, then give them a good wiz with the stick blender. Multiple colours you split the emulsified batch and colour the same way
Fragrance Oils Max 5%. Always check usage limits with your supplier for soap / wash off products, every fragrance oil has a different usage rate
Essential Oils Max 5%. Always check dermal limits and dermal maximums with essential oils. That includes using multiple essential oils in a blend
Natural Vitamin E (Mixed Tocopherols) Antioxidant 0.5-2%. I add 0.7% to my essential oil blend and add after emulsion or thin trace. If your recipe is fragrance free add at light trace. Vitamin E oil is not the same as Mixed Tocopherols 50-100%. It will not function as an antioxidant in soap and extend shelf life or minimise DOS. This oil soluble antioxidant is best suited for hair, face and body soaps
Grapefruit Seed Extract (GSE) Antioxidant

A strong water soluble anti-oxidant like Natural Vitamin E. Extends shelf life of your bar, slows down rancidity and minimises DOS. Add 0.25% to thin trace and work quickly as it can speed things up a little. Best suited in bar & liquid soaps designed for cleaning as it is water soluble and won't add to Superfat percentage

Citric Acid - Prevents soap scum & minimises DOS

Acts as a chelating agent to reduce or eliminate soap scum. Dissolve into your distilled water before adding the Lye. Works for both sodium and potassium hydroxide. Be sure to check your lye calculator as to how much to add and the extra lye needed as the citric acid will consume some of the lye to create sodium Citrate

 

It is also believed adding citric acid acts as an antioxidant, reduces DOS and extends the life of your soaps

Be sure as with any additives, there are no funky ingredients. Avoid anti-caking agents in your salt. I hope you find the information useful. Feel free to comment on any additives below that might be useful for others 🙏
