Soap Lye Calculator

Developed and tested by experienced soapers, this handy lye calculator is all you need to make bar (NaOH), liquid (KOH), or mixed soaps. Soap Lye Calculator will accurately calculate required lye amounts, the estimated amount of liquids for your recipe, and the soap's composition and properties. Our soap calculator includes a number of features necessary for professional soap making.
Features:
* 136 oils supported.
* Functionality for making bar, liquid, and mixed soaps.
* Emailing of soap recipes with an easy-to-read tabular format html file and a .csv file (you can open and edit .csv files in Microsoft Excel).
* Save soap recipes to .csv and .html files on your device.
* Editable samples for each kind of soap to make getting started easier.
* Recipes automatically saved into your list.
* Extra functionality allows for making cream soaps (calculates water and glycerin needed to make a cream soap).
* Properties are calculated for each soap (fatty acid composition and soaping properties).
* Each soap is given a cleansing factor. The cleansing factor is a representation of the total amount of soap molecules within a weight unit of any soap expressed as a % comparison to that of Fractionated Coconut Oil soap.
* Option for specifying fragrance details.
* Configurable in grams, ounces, and pounds.
* Simple, easy to use interface.

I'm being warned this app needs to be updated to work with Android 10. Otherwise it works well. Will it be updated?

Please update the app so I can continue to use it!! Please please please

Can I give my soap a name, it save it as untitled? please help

A great app that has a wide variety of oil to select from. Very straight forward process , which makes inputting the information user friendly. My only issue with this app is that if you have it loaded in multiple devices, they are not uploaded to all of them. I would hope that you is fixed so that we don't have to go from one device to the other with our recipes.

Pretty nice, can confuse a beginner though with all those lye options. I personally would like to see an option to take a picture of that batch/bar and set a reminder of when the cure process is done! If you add that, it's then 5☆☆☆☆☆

If you don't make soap, this app will be confusing. If you do make soap, it's awesome! It calculates the lye for bar, liquid, mixed and cream soap. And you can export a copy if any recipe you create for safe keeping so if the app is ever reset or lost, you still have your recipes. Highly Recommended! Add soap results picture option? please! --- If you had a yield button that allowed for changing the amount all at once. Wow....got busy on the CVS/HTML combo! Love it. Email works now...THANK YOU!

But would be better with the capability to edit batch size when formulating using percentages. Still, the best free calc I have come across.

I would like to see the ability to change batch size, and switch between percent/oz/gram back and forth, this will help tremendously when sizing up or down a batch.

I agree with others re: uploading pictures and changing amounts. What I'd really like is a seperate section for *notes*. Having all my scent blend recipes in one place would be helpful.

This app is good, let's make it perfect: 1. An exit button, 2. Batch proportion change options (check out the app "My Recipes"), 3. explanations of acids, and 4. hardness & softness ranges. Thank you!

I love this app. I had previously had a problem emailing my recipes, but have had a fun and very positive experience working with Rich Java Labs to create a solution. I run every recipe through this app and really like having backups of my recipes.

Emi. A. Sep 15, 2014     

Its so detailed I can't complain the options are easy and friendly. The one and only thing I would love to see on this is a option to add a picture, since when I pull the recipe I am once again reminded how I swirled the decor of the soap in that recipe. This would make it the perfect app for .either way its great.

I see you have option for soy and/or palm shortening, but no option for just plain vegetable shortening / Crisco. Can you add it to your list of oils please :-)

Very good app and the developer is VERY friendly and helpful.:)

The best app for soap making

Sav. d. C. May 22, 2014     

Love this app. Some really nice features like the fact that it saves your recipes AND sends them to your chosen email! The facebook page is extremely informative and helpful, queries are dealt with quickly and efficiently. Life on the bus will never be the same again.....

This is by far the best soap app I've seen. Everything is customizable to fit my needs. So much that I can change the KOH purity percentage to match that of the Summer Bee Meadow website's KOH output. This is scary accurate in comparison to Soap Calc, without any changes to KOH purity. Good job!

This app is full of features that the other few apps don't include. The list of oils is wonderful. The option to make bar soap, liquid soap or a soap containing both lyes makes it my go to when I am out and about. Being able to compare properties of your creation saves me a lot of time. Plus the added benefit of sending your formulation by e-mail to yourself I love, too.

Thanks to my friend Bonnie for reccomending me this useful and excellent app

Chi. Y. L. May 13, 2014     

Easy to use and nice design. The Cleansing Factor property makes it easy to compare soaps quickly. I haven't seen this in other soaping apps. Keeping my email in Settings is a nice feature too - it means I don't need to type in my email address when I want to export a soap recipe.
