How to Make Liquid Soap From a Bar

By doing a very simple process we will be able to transform our soap bar to liquid soap. This will help us to exploit the strengths and advantages these two states of the material bring to us. On one side the solid state, ideal for storage and transportation of soap. On the other hand the liquid state, perfect for later use, giving us optimal hygienic conditions.

Mediante el sencillo proceso que explico a continuación seremos capaces de transformar nuestras pastillas de jabón a jabón liquido. De esta manera podremos aprovechar las cualidades y ventajas que nos aportan estos dos estados del material. Por un lado el estado sólido, ideal para la conservación y transporte del jabón. Por otro lado el estado liquido, perfecto para su posterior utilización, dándonos unas condiciones higiénicas óptimas.

Step 1: Required Elements / Elementos Necesarios

Step 2: Weigh / Pesar

First, we must weigh the amount of soap we will use. In our case we want to fill a 400 ml dispenser. so we will need approximately 120 grams. of soap. (around 300 gr. of bar soap is needed for each quart of liquid soap).

Then weigh the vessel in wich you will introduce the water later. We zero out our balance (tare button).
We need a quantity of water equivalent to four times the weight of bar soap used.
In our case 120 gr. of soap X 4 = 480gr. of water =  two glasses of water

-

Primero debemos pesar la cantidad de jabón que vamos a utilizar. En nuestro caso queremos rellenar un dispensador de 400 ml. por lo que necesitaremos aproximadamente unos 120 gr. de jabón. (se calculan unos 300 gr. de jabón en pastilla por cada litro de jabón liquido que queremos obtener).

A continuación pesaremos el vaso en el que posteriormente introduciremos el agua. Ponemos a cero nuestra balanza (botón de tara).
Necesitamos una cantidad de agua equivalente a cuatro veces el peso del jabón en pastilla utilizado.
En nuestro caso 120 gr. de jabón X 4 = 480gr. de agua = dos vasos de agua

Step 3: Mix / Mezclar

We grate (with the help of the grater) the soap bar, introducing the chips into the metal pot. Once the soap is grated we introduce the water.
Note: Depending on the type of soap and its composition will be more or less difficult to grate. If it were too complicated or in case you do not have a grater you can shred the soap, place it in the pot  with the water and mince it with an electric mixer.

-

Rallamos (con ayuda del rallador) la pastilla de jabón, introduciendo las virutas en el cazo metálico. Una vez rallado el jabón introducimos el agua.
Nota: según el tipo de jabón y su composición será más o menos dificil rallarlo. Si fuera muy complicado o en el caso que no tuvieramos rallador, podemos desmenuzar la pastilla de jabón, introducirla en el cazo junto con el agua y triturarlo todo con una batidora eléctrica.

Step 4: Boil / Hervir

Take the pot with the mixture we have made to its boiling point.
It is important  to stir well from time to time to disintegrate the soap completely.

Once the mixture begins to boil we turn the heat to the minimum as it tends to foam (the higher temperature more foam).
Keep the mixture boiling for about 10-15 minutes (it is important you let it this time, if you want the two components do not separate) later.

-

Ponemos el cazo con la mezcla que hemos hecho al fuego y la llevamos a su punto de ebullicion.
Removemos bien de vez en cuando para facilitar al jabón que deshaga totalmente.

Una vez la mezcla empieze a hervir deberemos bajar el fuego al mínimo ya que tiende a hacer espuma (a mayor temperatura más espuma hará).
Mantendremos la mezcla hirviendo durante unos 10-15 minutos (es importante respetar este tiempo si queremos que luego no se separen ambos componentes).

Step 5: Stand and Bottle / Reposar Y Embotellar

We let the mixture sit for half an hour, stirring occasionally to avoid lumps.
Once tuned, proceed to fill our container being careful not to spill out of it.
We close our package and we have already set our liquid soap.

-

Dejamos reposar la mezcla durante una media hora, removiendo de vez en cuando para que no se formen grumos.
Una vez templada procederemos a rellenar nuestro recipiente, con cuidado de no verter la mezcla fuera de él.
Cerramos nuestro envase y ya tenemos listo nuestro jabón liquido.

Step 6: Use It / Utilizar

After few hours we will see how the color and appearance of our soap has completely changed. According to the proportion described in step number two, soap must have the correct density and we will be able to use it without problems.
Anyway it may happen that:
- The soap has become too liquid. Solution> Go back to step three and add more soap. Proceed with the following steps.
- The soap has become too thick. Solution> Just add a little warm water and mix well with the rest of the soap obtained until you get the right consistency.

-

Al cabo de unas horas veremos como el color y aspecto de nuestro jabón ha cambiado por completo. Según la proporción descrita en el paso número dos el jabón habrá espesado correctamente y podremos utilizarlo sin problemas.
Aún así puede pasar que:
- El jabón haya quedado demasiado liquido. Solución> Vuelve al paso número tres y añade más jabón. Procede con los siguientes pasos.
- El jabón haya quedado demasiado espeso. Solución> Simplemente añade un poco de agua tibia y mezcla bien con el resto de jabón hasta que consigas la consistencia adecuada.

hi, I have a palm and coconut bar soap. I dissolve it in 80% of water, after few day the soap become paste again.

I grated the 75 gram bar soap really fine and then added 300grams of water. I heated it at low flame in a steel pan, stirring every 5 minutes.
After cooling my soap is jelly like and lumpy..
What can I do to make it right?

[aniceprsn54]

One other thing, if, after having done the entire process, you find that the liquid soap is still fairly much a liquid instead of having thickened up, take a small amount, like a cup or so, of the mixture and heat it up and then add 3 Tablespoons of kosher salt to the heated liquid. Stir until the salt dissolves and then add the mixture back in to the soap base you've created. That should help thicken it up nicely so it's not like water any longer.

Good luck!!!!

What about the gasses that go out from the boiling liquid?

Is it safe?

thr soap contains alot of chemicals.

Is it danger to breath those vapors?

[aniceprsn54]

If you do it the way I have learned and have done myself, you heat the water to boiling first. Turn off the heat and then introduce the grated soap into hot water. If you do it the other way around, you have a great chance of the mixture boiling over and making a terrible mess!

If you're afraid of vapors, you can always purchase masks in the drugstore area of your grocery store, or go to a pharmacy. They can help you there. Or you can even get them at the hardware store. There are a number of different types available to the public.

i have hard tap water.

Is it matter?(calcium/magnisium mineral etc.)

Should i use soft water?

[aniceprsn54]

You actually should always use distilled water so you don't introduce any more chemicals into the soap than are already there.

You can buy 800mL liquid hand soap from samsclub.com. They are 2 for $5.75 with free overnight shipping. I just bought 2 to use in my wall mount dispenser. I use them in my shop......really nice. New dispenser costs about $12.00 + free s/h.

[aniceprsn54]

That is extremely expensive soap, considering you can make your own with Ivory soap, which is really one of the best to use because of the purity, and you can get an entire gallon for around $1.50. Of course, if you want to add a scent to it or essential oils like lemongrass or tea tree oil for their antibacterial properties, it will raise it a few pennies, but not by much. :) I just wanted to point out how inexpensive it can be to make your own, and actually how much better it is for your skin.

Iike this but is there any way i can turn liquid soap to a bar?

when i tried i left it out side to freeze in cold water but only the water around it frozen soild

[babyruthwhit]

I just made some liquid soap using the scraps from our Irish Spring soap. It is awesome and so easy to do. I even washed the dinner dishes with what was leftover in the pot. I would suggest trying to keep the same type of soap scraps so you dont get a strange smell oor some kind of weird chemical reaction.

[MsJan]

Sorry to say but I use to work in a grocery and Irish Springs was one of the first things I became very ill from. I broke two ribs twice form coughing due to ordors from soaps. Be very careful to the toxic products you use. Becuase now my system has broken down to more chemicals I have to make my own soap which has no smell but is healthier. I also now sell them and give for gifts to help others stay healthy. My kids keep requestiing for me to make more. Remember A Healthy Home Will Have No Smell.

[ally-oops]

I recently made my own cold process soap and made liquid soap from the crumbly bits. Works very nicely! Thanks!

[Fredy21]

In compliance with the "be nice" comment policy (which, apparently, you are not aware of), I would only suggest that you type "Pastillas de jabon" in your favourite image search engine. Then you might consider deleting your somewhat "not nice" comment concerning this contributor's Spanish version...if only to comply with the "be nice" comment policy!

Trying to help out since I speak the language every day..deleted.

[elgati]

‹‹Pastillas de jabón›› es un uso completamente normal en España. Ellos dicen ‹‹pastillas›› y nosotros decimos ‹‹barras››.

Por cierto (y sin ánimo de polémica) quizás te interesaría saber que en tu página ‹‹jabón›› y ‹‹perfume›› no están escritos correctamente.

[luvasu]

Pastilla, barra, jaboncillo... todo es CASTELLANO, se usa una u otra palabra dependiendo de dónde eres o dónde estás.

[ansanma]

Me ha gustado mucho ver que has hecho el instructable en dos idiomas, yo también lo suelo hacer. ¡Enhorabuena! ;)

[CalvoViejo]

Estoy completemente de acuerdo!! Sería muy bien si más personas escribieran en dos (o aún más) idiomas. Felicidades!!

[Clapperclawed Cankerblossom]

Cool idea. Plus I like to see that so many French speakers are reading about how to use soap.
