Whether you’re planning to sell your handmade soap, or just hoping to make a large batch of soap, buying bulk oils for soap making keeps your craft budget-friendly. You can buy soap making oils from a wide range of sources, from local brick-and-mortar stores to online wholesalers. In this article, we’ll discuss considerations before buying in bulk, plus the best places to find large quantities of base oils.

You can redirect the money you save from buying base oils in bulk to other soap making supplies such as micas and other colorants, dried botanicals, luxury oils, or fancy soap molds. Aside from saving you money, bulk buying saves time (fewer trips to local stores, or precious time scouring the internet). Besides, who doesn’t want to save money nowadays?

Let’s get started!

Considerations before you buy bulk oils for soap making

Before you go all-in on the best deal for wholesale bulk castor oil, for example, read over a few important considerations to keep in mind.

  • Try before you buy: Quality soap comes from quality ingredients. Try to order small batches or samples of oils first before buying in bulk. Some online suppliers such as Wholesale Supplies Plus sell small sample kits with a variety of liquid oil in small quantities. After all, you don’t want to end up with a large lot of oil that is subpar.
  • Make a list: Compile a few of your favorite natural soap recipes and make a list of common oils used as a soap base. Common base oils include avocado oil, coconut oil, olive oil, palm oil, plus lard or tallow.
  • Shipping costs and shipping options: If you’re buying online, it’s best to research shipping prices and options beforehand to save yourself from an (unexpected) hefty price tag upon checkout. Does the wholesaler have a minimum order quantity? Wholesale pricing is only good if the shipping costs to your area are reasonable.
  • Shelf life of oils: Shelf life is a huge consideration when buying oils for soap making in bulk. Different oils and body butters have varying shelf lives. For example, soybean oil is high in linoleic acid, which gives it a shorter shelf life. Many varieties of vegetable oil come in high oleic acids such as high oleic sunflower oil, high oleic safflower oil, and high oleic canola oil. These types of oils have a longer shelf life compared to their traditional counterparts. When buying bulk oils, look at the best-before date (if shopping at a brick-and-mortar store). And consider buying oils with a longer shelf life to ensure that you use them up. After all, nobody wants rancid oils in finished soap bars.
  • Quality of oil: Every soap maker has different standards and preferences (as do your customers). If fair trade, organic, or non-GMO is important to you, make sure you do your research before buying bulk.

Where to find bulk oils for soap making

Not everyone lives near a local soap supply store, nor a big box supermarket. If this is you, you’ll need to get creative with local suppliers, or source your ingredients from an online wholesale supplier.

Tip: When buying oils for your next batch of soap, avoid blended vegetable oils as this makes it hard to calculate the exact amount of lye required to saponify your homemade soap recipe. Stick with vegetable-based oils labelled as 100 percent pure, such as 100 percent sunflower oil.

Local butcher or farmer for lard or tallow

If you use lard or tallow, the best and cheapest source of this is from your own animals! And if you don’t have your own, the next best thing is to forge a relationship with a local butcher or farmer.

Many butchers regularly toss out trimmings and fat. If you don’t mind a bit of extra work to render your own fat, you can have a steady supply of fats to make oodles of soap.

Costco and/or Costco business center

I’ve been shopping at Costco for years and regularly stock up on bulk foods and oils. But recently, a Costco business center opened up in town.

A Costco business center is essentially a version of the regular store that caters specifically to the needs of small businesses and restaurants. So, you’ll find a wide selection of office supplies, food and produce, and yup, bulk oils for soap making.

You can find base oil like a tub of refined coconut oil (3.79 L) and an enormous box of canola oil (17.3 L).

The good news is, you don’t need to be an official business to shop at the business center—but you’ll still need a regular Costco membership. You can get items delivered to your doorstep, but you’ll need to spend a certain amount (around $250) to forgo the shipping fee. You can also return items to any Costco warehouse worldwide.

Depending on your local store, you might find:

  • Avocado oil
  • Canola oil
  • Coconut oil
  • Corn oil
  • Grapeseed oil
  • Large box of deodorized lard
  • A wide variety of olive oil
  • Peanut oil
  • Sunflower oil

Local restaurant suppliers

Restaurants need a steady supply of bulk cooking oils, and you can use many cooking oils for making cold process soap, body products, and other homemade personal care products.

Many restaurants use high oleic versions of oils as they last longer and have a longer fry time. The bonus to you as a soap maker is that your soaps will also last longer when choosing high oleic varieties of oils.¹

Depending on your local store, you might find these cooking oils:

  • Avocado oil
  • Canola oil (high oleic)
  • Coconut oil
  • Large cubes of lard
  • A wide variety of olive oil
  • Peanut oil
  • Sesame oil
  • Sunflower oil (high oleic)


Of course Amazon had to make the list of good places to buy bulk oils. Look around and you might even find a free shipping option.

A few good oils to buy here include:

  • Castor oil: While you might find a small bottle at a local pharmacy, the prices are exorbitant. Stock up on this invaluable soaping oil—castor oil produces a luxurious stable lather.

If you want a bottle of lye pronto, and don’t want to order online, try checking out your local hardware store, or local chemical supply company.

Related questions

What oil makes the hardest soap?

Palm kernel flakes have a hardness score of 90 according to Soap Calc, which to my knowledge is the hardest soap making oil. Add PKO flakes if you want to create a harder bar of soap.

Hard oils are those that are solid at room temperature (think coconut oil, lard or tallow, and shea butter). You can use these oils as part of your soap recipe to increase hardness in your soap bar.

There’s also a special category of oils known as brittle oils; these oils are beyond hard—they require some effort to chip or chisel them out of the jar. Brittle oils include babassu oil, palm kernel oil (and palm kernel flakes), and cocoa butter.

What is the cheapest oil for soap making?

The cheapest oil for soap making would be if you had access to your own lard or tallow. You can make good soap using animal-based fats you render yourself. However, not everyone is a fan of using lard or tallow. There are many affordable vegetable oils such as canola oil, coconut oil, castor oil, olive oil (pomace), palm oil, rice bran oil, soybean oil, and sunflower oil.

Of course, price depends on several factors, including where you live, whether you buy online, and whether you buy in bulk.

How many bars of soap does 10 pounds make?
