Coconut-Lime Soap

Yesterday morning, I looked out the window while I was getting ready and decided, “You know what? It looks like flip-flop weather!” I’m not quite sure what got into me, but I got dressed and was completely convinced that I would get to work and everyone would be wearing summer attire.

Coconut Lime Soap 3

It was a bit of a reality check when I walked out my door and realized the temperature was balmy 38 degrees. When I arrived at work there was not a sandal, flip-flop or short sleeve shirt in sight. Apparently, it’s not quite summer yet.

Coconut Lime Soap 4

Once I got home from work that evening I grudgingly put my flip-flops back in the closet, anxiously awaiting the day when they would make their grand re-entrance. Until then, I’ve decided to fulfill my craving for summer another way: making Coconut-Lime Soap.

Coconut Lime Soap 1

This soap is made with coconut milk and coconut-lime fragrance oil. With the added chopped coconut and lime zest exfoliant on the edge, these bars smell like summer on a beach. (Just make sure it actually is summer before wearing those flip-flops.)

What are your favorite summer fragrances?

Coconut-Lime Soap
Makes about 16 4 ounce bars of soap

For the full cold process soap making instructions, check out Tiffany’s beginner’s soap making tutorial

Base Oils
15 oz. coconut oil (34.09%)
15 oz. olive oil (34.09%)
8 oz. sunflower oil (18.18%)
6 oz. safflower oil (13.64%)

Lye Solution
14 oz. coconut milk (for more on soap-making with milk, click here)
6.25 oz. lye

When making soap with milk, freeze the milk first, to at least a slushy state, otherwise the milk will burn or curdle when mixed with the lye. When creating your lye solution, very slowly mix the lye, a small amount at a time, into the frozen milk slush. Complete the rest of the recipe as you normally would.

2 oz. coconut-lime fragrance oil
Lime zest and chopped dried coconut for exfoliant (optional)

As always, remember to let your soaps cure for 4-6 weeks before using or gifting.

    Haha. Thanks! :)

  5. 30 mos, 2 wks ago

    Thanks! You definitely should make soap! It’s not difficult and once you get the hang out it, it’s easy to create your own recipes. I’m definitely addicted to soap-making! :)

  6. 30 mos, 2 wks ago

    Thanks! :) It’s super fun coming up with recipes – you should give it a try! My sisters recently started making soap and I think they’re officially hooked.

    where do you buy your oils? I used fragrance oil one time and my soap seized up

  8. 30 mos, 2 wks ago

    You can get a number of essential and fragrance oils for soapmaking from We’ve gotten many of our oils from them. This particular coconut-lime oil used in this recipe, I bought at a store near me. However, does sell both a lime essential oil and a coconut fragrance oil that you could use for this recipe. Hope that helps! :)

    What a great idea. I had never thought of coconut milk in a soap but should have! Thanks for a beautiful summer soap!

  10. 30 mos, 2 wks ago

    Thanks! This was a first for me using coconut milk and so far I love it! I’ll definitely be making more recipes with it. Glad you enjoyed the post!

    This might sound dumb, where do you get lye from? I would love to make my own soap because I have skin problems and regular soap sometimes hurt.

  14. 30 mos ago

    Thanks! So glad you like the blog and the recipes! :)

  15. 30 mos ago

    Not dumb at all! I order lye from The Lye Guy ( My skin has been so much better since making homemade soap – and you can adjust and find recipes based on your own skin preferences. Hope that helps! :)

    I’ve never made soaps before but I’m really interested. Should I start with something like this or maybe an easier one? And by folloeing the same directions you mean the temperature and the mixing?

  17. 29 mos, 3 wks ago

    I think the best way to start soapmaking is to use Tiffany’s soap tutorial She gives you EVERYTHING you need to know about soapmaking, including a super easy beginner’s recipe. When I first started, I just used her beginner’s test recipe because that way if I made a mistake, I didn’t waste money on additional ingredients like fragrance oils. Visit this link: for the full tutorial. :)

    Sounds lovely! Looking forward to giving this one a go How long can you keep the soap for once made? I’m a soap making newbie and not sure!

  19. 28 mos, 3 wks ago

    Generally, once the soap is made, it has a shelf life of about a year. However, that can change depending on the ingredients you use. Here is an article that may be helpful in answering your question further:

    For the coconut milk, did you use the canned coconut milk, or the kind in the fridge section?

  21. 28 mos, 2 wks ago

    For this particular batch, I used coconut milk from a can. I may try my next coconut milk recipe with the refrigerated kind and test out the differences, though. :)

    28 mos, 2 wks ago

    I prefer to use EO rather than fragrance oils. Any suggestions?

  23. 28 mos, 1 wk ago

    Sure! I would suggest just leaving the coconut fragrance out and using all lime essential oil instead. You won’t have the same coconut scent, but it will still be “coconut lime” soap since you’ll be using coconut oil and coconut milk in the rest of the recipe.

    Hi. I would like to add some mandarin zest to this. Also, the folks I am making this for have kids with eczema and psoriasis. I read that sesame oil is good for that….any tips on modifying this recipe?? Thanks. And fyi…I’m gonna be on this site ALOT friends. :)

  27. Kim
    26 mos, 3 wks ago


    I do the hot process method because I want my soap sooner!! Can you make a recipe with milk in a crockpot?

  28. 26 mos, 3 wks ago

    Mandarin zest would be great! That’s a wonderful idea. In soap recipes when sesame oil is used, it typically makes up about 5-10% of the total base oils. For this recipe, which is 44 oz of base oils, you would replace anywhere from 2.2 – 4.4 ounces of one of the oils above (I suggest replacing part of the sunflower or safflower oil) with sesame oil. Make sure to run your modified recipe through a lye calculator ( because the amount of lye could change based on the oils you use. Hope that helps!

  29. 26 mos, 3 wks ago

    For milk recipes, I recommend the cold process method, but here’s a helpful article if you do want to do a milk soap using the hot process method: That article suggests using powdered milk for hot process milk recipes. I’ve never done that yet, so if you try it please let us know how it goes!

    Thank you for the guidance. I will give it a try. Also, my buddy made me a real hefty soap mold, and he wants to make more. Do you guys talk about molds on here?

  31. 26 mos, 3 wks ago

    We haven’t posted much about soap molds. Tiffany built her own mold and hopefully we’ll post a tutorial at some point on making your own, but we don’t have that info up yet – but stay tuned! :)

  32. 24 mos, 2 wks ago

    Hmmm….lime and coconut. That sounds incredible!! I’ve been wanting to make soap again and think I’ll try this recipe. Thanks so much for sharing it. Do you use dried lime zest on top?

  33. 24 mos, 2 wks ago

    Thank you! Yes, I did use some lime zest and dried coconut flakes for the top. I hope you like the recipe!

    Hi, love your site and your soaps looks great! I would try to make this one, but cant get any safflower oil where I live.. Do you have any other suggestions of oils to use instead?

  35. 23 mos, 3 wks ago

    So glad you like our site and recipes! According to this chart:, you can use canola oil instead of the safflower oil. Just make sure to run the revised recipe through a lye calculator ( to see if you need to adjust the quantities of lye in the recipe.

    Hey there

    LOVE the blog and am excited to start soap making very shortly! Just wondering about base oils, do you use liquid coconut oil or the kind that is semi solid at room temp.

  37. Kim
    23 mos ago

    Can you do this recipe with hot process in a crockpot? With the milk, just wondering if that would work?

  38. 22 mos, 3 wks ago

    So glad you’re enjoying the blog! I used coconut oil that is semi-solid and melted it in the microwave when I mixed all my oils together. Happy soaping!

  39. Anne Luttrull
    21 mos, 3 wks ago

    Do you bring your oils to 105 degrees and match it to the lye temp or are the oils room temp? I am really wanting to learn to make this. Thanks for sharing.

  40. 21 mos, 3 wks ago

    I haven’t tried this particular recipe using the hot-process method. However, according to other articles I’ve read, milk soaps can still be made in a crock-pot. Here’s a helpful article for additional info: Hope that helps!

  41. 21 mos, 3 wks ago

    Good question! We recommend having both the lye solution and the base oils between 100 and 125 degrees when you mix them. Happy soaping!

  42. Manca

    Hey there! Thank you for this lovely recipe. I hope you feel flattered if I tell you that among thousands of different recipes one can find on the interwebs, I decided to start my soap-making career right with this one. ;)

    But … I’m not sure all has gone the way it should have. I used 170,5 g coconut oil, 170,5 g olive oil, 91 g sunflower oil, 68 g safflower oil, 177 g coconut milk (frozen) and 70 g lye, plus I added 20 g lemon EO, a good handful of dried coconut and around 2-3 spoons of lemon zest at trace (I was using a hand blender). I made a batch 3 days ago and cut it into 8 bars around 48 hours after the batch was made. The problem is that the bars are still kind of soft (although a lot thicker and harder than when I poured the soap in the mold) and they don’t seem to be getting any harder. When I hold one in my hands, it seems as if it was melting. I took one small piece of it and washed my hands with it and it seemed ok. But they are not real soaps, they are way too soft. I did use lemon instead of lime (since I got bio lemons from my friend’s garden), but I don’t think that should make a problem. I also do know I should wait 4-6 weeks before they are ready but I am afaid they were too soft even at the time I was cutting it. What do you think, where did I go wrong? Is this normal and will my soap bars eventally get hard enough to use? Or should I try rebatching it? And if, how?

    I know, so many question, but I think you as the authour of the recipe and a pro can help. ;) And hey, the soap smells amazing! I really don’t want to throw it away … I really hope you can help.

    In response to Manca: run your recipe through a lye calculator always. It could be that there wasn’t enough lye which I think is the problem here. Also, when you make a soap that is all or largely olive oil, it takes months to cure. I like using for their easy to use lye calculator. The lemon shouldn’t make a difference. I hope I helped a little. Good luck!

  44. 20 mos ago

    I am completely consumed with all the possibilities of soapmaking but I am a tad leary of working with Lye. If I wanted to start out with a Melt and Pour soap base how would I adapt the recipes?

  45. 19 mos, 3 wks ago

    For melt and pour soaps, I would suggest purchasing a kit specifically made as melt and pour. For melt and pour soaps, lye has still been used in the original product – it’s just that you personally won’t have to use the lye because someone else has already handled that chemical before it becomes a melt and pour kit. Hope that makes sense! Here’s a link for melt and pour soaps:

  46. 19 mos, 3 wks ago

    Sorry for my delayed response on this and I hope you’ve been able to salvage these soaps! As Diana mentioned, definitely double check your recipe using a lye calculator. If you do need to rebatch, I’ve got some helpful tips and links that I included in this post (when I had to rebatch): Hope that helps and good luck!

    Thanks for the great recipe, but once i added the lime zest, it turned neon orange, did I do something wrong??

  48. Manca
    19 mos, 2 wks ago

    Heya, thank you for your answers. I did run a lye calculator before starting the process of soap making and I guess I even triple checked it – just to be sure it works.:-) And now, 7 weeks after the soap was made, I think I made too much of drama for nothing really. I think the soap works fine! After this coconut-lemon soap I made three other soaps and realized that apparently each soap’s hardening process is different. This one’s pace was just a bit slowlier than some others. Is this possible?

    Also, Sarah, can I please ask you to write few words on how long can different kinds of homemade soaps sit unused – e.g. how long can one store them in a cupboard before they get bad? Thank you.

    May I ask the dimensions of the slab mold you use? Your soaps look great! I have several of the recipes waiting for a slab mold to be made! Cant wait……..

  50. 17 mos, 4 wks ago

    Those pictures looks lovely.. I like natural and organic soaps, they don’t cause the dry feeling that you can experience with commercial.

  51. Janet Spence
    17 mos, 1 wk ago

    Just found your site and love it :) I just got back from my health food store and they had neither lime or coconut EO, so I am going to take a walk on the wild side and use lemon and peppermint. I will let you know how it turns out scent wise when it isout of the mold.

  52. 17 mos, 1 wk ago

    The lime zest may change color a bit as it dries out. Mine turned to a bit more muted green/yellowish as time went on, but it didn’t seem to cause any issues with the soap. Sorry that happened! Even though the zest color changed, it shouldn’t affect the quality of your actual soap.

  53. 17 mos, 1 wk ago

    I don’t have the dimensions available at the moment, but the mold I have is a 4lb mold, which makes 16 4oz bars of soap. Hope that helps!

  54. 17 mos, 1 wk ago

    Thank you! I agree! Handmade soaps are so much more moisturizing than most commercial soaps!

  55. 17 mos, 1 wk ago

    So glad you like the site! I used a coconut-lime fragrance oil, not EO, which may be why you couldn’t find it at the health food store (it’d be more available on soap-making supply websites). This recipe would work well with other essential oils, though. Lemon and peppermint will probably work great! Good luck and happy soaping!

    So I just made this recipe but instead of 2 oz of fragrance oil I totally used 2 oz of tea tree oil. I am wondering if i used too much tea tree oil because my room smells of tea tree. Will the soap die down some once the soap cures?

  57. 16 mos, 1 wk ago

    The scent may soften a bit as the soap cures, but different oils need to be used in different quantities. Typically, we suggest approximately 0.7 ounces per pound of Base Oils for most Essential Oils, 0.9 ounces per pound of Base Oils for Citrus Oils and 0.4 ounces per pound of Base Oils for more pervasive oils like mints and spices. Tea tree oil would definitely be a more pervasive oil, so you don’t need as much in a soap recipe as you would a citrus essential oil. Your soap will still smell and work great, but that could be why it’s a bit on the strong side. Hope that helps!

  58. Glad to hear the soap turned out! Yes, depending on the oils, the hardening timeline can be a little different. As far as storing, sometimes soaps with essential oils or fragrance oils can lose their scent after about a year or less, so I’d suggest using up the soap within a year. Also make sure that you store them in a way that allows them to breathe – don’t store in an airtight container. Happy soaping!

    By coconut milk, did you mean the water in coconut or crushed coconut meat ?
    I’m already thinking of going commercial with milk soap, because people here love ”crazy” things!

  65. 9 mos, 1 wk ago

    Amazing, love coconut lime but I’d add yogurt in these. People love them.

  66. alison
    9 mos, 1 wk ago

    Do you use the yogurt in place of the milk? I’ve never heard of that, so just curious also as to the benefits of using yogurt.

    I’ve made a batch as per the above recipe, gave it out this Christmas…everyone loved it!

  67. 9 mos, 1 wk ago

    By coconut milk, I mean the milky liquid that comes from the coconut meat. What I use for this recipe is the coconut milk that comes in a can from Trader Joe’s, but other brands would work just fine, too.

  68. 9 mos, 1 wk ago

    Interesting idea! I’ve never used yogurt in a soap but now I’ve got to try!

    I’ve never used yogurt, either, but I will definitely have to experiment with that! So glad that everyone loved the soap! :)

    Sorry if I’m asking a question you have already answered, but do you use canned coconut milk or the coconut milk that is in the dairy section at the grocer?
