Hole and liquid soap inside, ask for help

[chinaAjing]

Hello, everyone, I'm new.From China
Makes handmade soap has encountered some difficulties.
First of all, I did not speak English
This is a translation software to translate the results
May not correct grammar

Please a lot of generosity
The way it is

Oil and sodium hydroxide, water is correct.
Room temperature of 25 degrees and humidity of 55 degrees
I made a few pot
Found several batches of soap cut cave
Or is empty
Have hole inside the soap
The hole inside is liquid
Liquid outflow, PH = 14 about


Do not know friends who know that this is what causes it?
Thank you very much.

Maybe the soap overheated? I have found small pockets of soap or fragrance oil but never one big hole this way.

 

[Fragola]

What oils and quantities have you used ?

Have you used fragrances or colors ?

thank you very much

My friend said there are bubbles in the soap slurry

Or indeed the violent reaction of the reason


Today , I again made ??a pot of soap

Solve the bubble problem

Soap slurry there is no insulation, placed in the library

Thank you, see you next time

I never joined in the soap slurry inside the pigment

Do not add essential oils and other things

Only base oil + sodium hydroxide + water = soap + glycerin

Because I was afraid of a chemical reaction of sodium hydroxide and additives


Here are my two formulations?



Olive Oil 30% Canola oil 19% Sunflower Seed 18% Coconut 15% Palm 18%
420g + 266g + 252g + 210g + 252g =1400g

56.28g + 33.0106g + 33.768g + 39.9g +35.532g=198.5g NaOH .

2.4 * NaOH =476g H2O

32?7 10?64 11?34 38?7 26?1 =119?INS






Camellia Coconut Palm
80% 10% 10%

1120g +140g + 140g =1400 G

152.544+26.6+ 19.74=198.884g NaOH 2.4beishui=477 g H2O

86.4 25.8 14.5= 126.7 INS



Part of the oil to buy in the supermarket?Other oil wholesalers buy in bulk goods

I suspect that the oil? But think about it may not be a problem?

Also suspected over sodium hydroxide?Buy caustic soda is not very good, which is not clean


The temperature of the oil and sodium hydroxide is about 40 degrees when mixing

Mixing with the mixer?Is stirring out of bubbles

Or high temperature reaction is too severe

Is currently exploring

Thank you for your attention

See you next time, bye

Here, we always use an excess oil (also called NaOH discount) of 5-7%.

For your 2 recipes, we would use maybe 190-191 grams of NaOH instead of 198.5 - 198.8.

Be careful about these things:

1. Check that your soap slurry is thick enough and mixed well and that it does not separate (like having liquid separated on the bottom of the container).

2. Check the weight of your ingredients

3. Avoid high temperature.

The soap reaction generates heat, but you can reduce the heat:

- work with smaller quantities and molds (500 grams instead of 1400)
- do not cover your mold
- keep it in a cool place for few days

Other substances can cause too much heat. For example, if you are working in aluminum container.

My friend said there are bubbles in the soap slurry

Bubbles can be ugly, but air bubbles are not bad. If soap is good, bubbles do not contain caustic liquid with high pH.

You should use a stick blender for mixing. If your stick blender catches air, you will get many bubbles. If you keep the stick blender submerged in your oils, you will get fewer bubbles.

You mentined your separated liquid was ph 14. This is lye separation that can happen from too little stirring. If you are stirring by hand a better method would be something mechanical, like an immersion blender or conventional blender. Even mixing the soap batter by shaking it in a sealed plastic bottle will work. The plastic bottle should be labeled as PP 5 as it is more resistant to high temperatures.

Certain oils will also want to separate from high water recipes. I am not so sure about camelia oil being more likely to separate but a water reduction and a better stirring method would help your separation problem.
