i really love liquid soap making and using my own handmade liquid soap but
to be honest with you i don't make it too often i find bar soaps a lot easier to make
they're a bit less fiddly so i tend to just stick with them however there's something really
satisfying about making your own liquid soap squeezing it out of the bottle nice and neatly
washing your hands all those things it's just a nice neat package so in this video
i'm really keen to share with you my recipe for 100 olive oil true liquid castile soap lots of
so-called liquid castile soaps out there dr bronner's not really true castile soaps in
the way that most soap makers think of a castile soap they're made with coconut oil and palm oil
and other oils in there but a true castile soap is 100 olive oil it's a very gentle soap whether it's
made in bar form or liquid soap form so that's what i'm sharing today at the end i'll show the
finished slope and i'll do a bit of a lather test so make sure you hang around for that and
as always this video is for your information and hopefully your entertainment and enjoyment as well
but if you're new to soap making please make sure that you watch my video on soap making safety and
really make sure that you understand what you're doing before you attempt any soap recipe
this recipe is really straightforward and it comes together beautifully it has four ingredients
olive oil water distilled water or demineralized water is okay too potassium hydroxide which
is the lye type that we're using and a little bit of glycerin as well and i'll explain that
through the video why that works so we'll get started and i'll show you how i make this soap
i start off by pouring my olive oil or weighing it straight into my crock pot so this is a
three liter slow cooker and it is perfect for this size batch of liquid castile soap i plug
that in and turn it on high just because nothing is pre-warmed and i really want to warm up my
oils to make this soap and while that's warming up i measure out my potassium hydroxide 104 grams for
this lye solution and i've got my gloves and my goggles on so make sure you know everything you
need to know about soap making safety before you attempt any soap recipe check out the
description box for more information about that i use 156 grams of distilled water or demineralized
water in this case and once you've got that poured out you can slowly add in the potassium
hydroxide and just stir it through gently until it dissolves it'll take a little while it'll
be cloudy to begin with and then it will become clear as it sits for a little bit
i also add glycerin in this recipe 104 grams and it acts as a solvent it does other things too
but the main reason i'm adding it is to help this soap to saponify and trace faster than it would do
without the glycerin liquid castile soap made with 100 olive oil is notorious for separating it takes
a long time to blend and get it to come together but the glycerin really speeds up that process
it also makes it a nicer soap to use as well so the lye solution just with the water and the
potassium hydroxide it's going in my oils aren't really up to the right temperature yet but it's
okay to get started at this low temp because the cooker is on high and it'll come up pretty quickly
then i'm adding the glycerin in as well at the beginning if you don't have glycerin
or you don't want to you can just use water and just check out the recipe on my website
that's linked below that gives all the details for the variations on how you can make this
and once everything's all together those four ingredients you can just start blending
that's really all there is to it to begin with so this takes about 10 minutes to come together
and you'll see at the beginning it's really oily and kind of yellowy oily looking and it
will want to separate a fair bit you've just got to keep blending and give your stick blender a
rest every now and then so it doesn't burn out and just blend blend blend for about 10 minutes
until it gets really thick and you're gonna see i do i did edit this a fair bit so it jumps forward
but you can see it's still at the beginning now it does have that really oily separating
clear look on the top but as you'll see you'll see the color starts to change it starts to get
lighter and more creamy and opaque looking once it starts to do that you know you're on your way
i check the temperature as i go through this process as well because i've still got that
crock pot on high because i'm really wanting to bring it up to temperature but i want to watch
it too so it doesn't get too hot ideally you want this soap to cook at around about 70 to 80 degrees
celsius but not too much hotter than that otherwise it'll scorch see there the color change
it's looking really creamy and light it's starting to emulsify there and it's getting a little bit
thicker as well i'm just checking the temperature again what have i got there 68 degrees celsius
that's pretty warm it's getting up there and 157 fahrenheit that is
so i think at this point yep i turn the the slow cooker down to the low setting
because you don't want it getting any hotter than 185 fahrenheit or 85 celsius and you can
see there after about 10 minutes it's really thick it's actually blended perfectly now it's really
nice kind of pudding texture it's a little bit grainy but that's all right as long as it's not
separated and there's no obviously really oily bits floating around on the top and it's nice
and thick and homogeneous then that's perfect you don't have to stick blend anymore for this recipe
i just stir it around there a little bit it's just kind of nice to play with um oh yeah show you what
it looks like it's quite thick you can see it kind of plopping into the into the pot there
so you get an idea of the texture of what it should be like once you've got to this point
this recipe it won't separate not if you're using the glycerin if you weren't using the glycerin you
may get more separation and it would probably take a lot longer but with the glycerin it's quite fast
and i just scraped down the sides of my pot to make sure there's absolutely no little bits of
unsaponified lye solution or anything on the side and then i cover it up and i cook it on
low heat so i turn the make sure the cooker is down on low or on the keep warm setting and set
your timer for 20 to 30 minutes this is after 10 minutes i couldn't help myself i had to check
you don't have to check it at 10 minutes but i kind of felt like it you can see the temperature
there it's 78 celsius which is 174 fahrenheit so that's a perfect temperature to cook this soap
like i said before you don't want it too hot because it will um expand and oxidize and you'll
get you know fluffy volcanoes soap which you don't want keep it nice and moderate in the temperature
department and i'm just giving it a bit of a stir totally unnecessary but quite enjoyable
for those of you who've made this kind of soap before you'll know what i'm talking about
um and then i just scrape down the sides again and put the lid back on
leave it for a bit longer so this is after 30 minutes in total so i left it for another
20 minutes and you can see the color has changed it's gone nice and translucent
and vaseline-y and it's just looking really beautiful you can probably hear the cicadas
and the dogs barking in the background it's night time that i'm recording this voiceover so
a few background noises um but look at that paste it's really nice it's very soft paste
because i use a fairly high water amount or liquid amount in this recipe but it works well
now i'm pretty sure this is ready to dilute and that it's fully cooked but i'm just going to
check so there's two ways that i check my liquid soap recipes i first do a ph test because i want
to make sure that this paste is completely cooked and saponified before i dilute it
so i've just dabbed a bit of water on there and you can see it's the paper is green it's between
eight and nine ph on my little ph paper strips so that's perfect and i also do a clarity test
whereby i just get a little bit of the paste on a whisk or whatever and just mix it in with some
distilled or demineralized water this probably won't work with tap water you need distilled water
that doesn't have any minerals in it and give it a shake give it a really good mix and
oh you can't see because of all those bubbles so you can get some isopropyl or any kind of alcohol
and spray on there it will get rid of the bubbles and then if your soap is completely cooked which
i already know this is but it will be nice and clear it does have a few little lumps of paste
still in there but generally that solution is nice and clear you can see my ring through there
if you know that's clear it's done so ready to dilute it now this is as simple as it gets i'm
adding about 1.8 kilos or 1850 grams of dilution water generally for this i would start with two to
one so two parts dilution water to one part paste and then add more if you need to because every
olive oil is different and your you may get more or less evaporation during your cooking process
than i did so just start conservative and then add more water later if you need to
there's a lot more detail about all of this in the website blog post of this recipe which gives all
the recipe details so i did let this dilute and just sit there on low temperature for a few hours
and then aft this is after a couple of hours of it just sitting i gave it a little bit of a help
along with the stick blender and that works really well if there's still just a little bit of paste
left blend it all through and it really finishes off that dilution um you can see it's a bit frothy
on the top but i sprayed a bit more alcohol on the top and it's all clear now perfectly diluted
this is still a bit runny because it's actually still a little bit warm it does thicken up
as it cools and i also found it during my testing for this recipe if you use extra virgin olive oil
you will get thicker soap thicker castile soap i i'm fairly sure this is the case it seems to
have been what's happened with me i'm pretty sure there aren't other variables i need to
test it a bit more but you could try using extra virgin olive oil and see how thick your soap goes
um but yeah this this batch is a little bit thinner than the previous one i did which had
more extra virgin in it but you know who knows it does thicken up though as it cools so i'm
just pouring this into my bottles i've got about 2.7 liters of finished soap from this
reasonably small batch so a little goes a long way and here i am just cleaning out my crock pot
it's like all olive oil soaps whether they're in bar form or in liquid form you don't get the
greatest most exciting lather but it lathers up reasonably well and i'm really happy with the
soap it's a lovely gentle soap it's excellent for hand washing and with the glycerin added to
it's a humectant so it makes the soap leave the skin feeling a little bit more moist than
other types of liquid soaps so the one on the left there this is the next morning the one on the left
has actually had some essential oils added some lavender and tea tree and it made it really
thick so don't thicken your soap before you add essential oils because some of them can really
thicken it up and you won't need to use any thickener if you do want to thicken your soap
though and you're not using essential oils i have a look in the blog post because i explain
how you can use the salt solution to thicken your soap if you really want to but i really
like this soap just as it is um it's gorgeous so a bit of a lava test with the hands now
i need to keep working on my hand washing technique
oh goodness so you see a lovely soap i really love this pure 100 olive oil liquid castile soap
um the real deal it as i said it's great for hand washing but honestly all of my liquid soap that i
make and usually there they've got a lot of olive oil in them i use them for everything
except clothes washing for washing my clothes in the washing machine i use my laundry soap granules
powder recipe it's a lot more concentrated than liquid soap even coconut oil liquid soap i don't
really like for washing my clothes so but i do use this in the kitchen use it for hand washing
in the bathroom and the kitchen and you can see there i'm giving the sink a bit of a scrub
it works rather nicely even though it's still a mild soap so that's about it everybody i
