Sodium Hydroxide Pellets (a.k.a. Lye) for Soap Making

Looking for sodium hydroxide pellets for soap making in Singapore? Soap makers in Singapore, unlike other countries e.g. America, are not allowed by law to purchase sodium hydroxide (lye) and potassium hydroxide for use at home. If you are interested in making soap here in Singapore, you will only be able to purchase AND use them in a workshop approved by NEA for lye. To encourage and promote the use of natural soap (made with lye) in Singapore, Singapore Soap had specially dedicated a part of our premise, approved for soap making and soap makers can come to our workshop to buy and use for soap making in our studio.

Sodium hydroxide is a controlled substance under Singapore’s Environmental Protection and Management Act. Unauthorized purchases e.g. buying online from overseas or marketplace platforms and using them under non approved environment could land you in trouble with the law.

For budding soaperpreneurs in Singapore, as mentioned, you can still use our soap making facility to make soap and try to learn more on the proper usage of lye before you start. Lye is a base i.e. a very strong akaline and you should use it with care. Some of the common questions asked by soapers in Singapore will be covered in this blog post.

Check out our blog post on Sodium Hydroxide Pellets (a.k.a. Lye) below.

What is Sodium Hydroxide?

  • Sodium Hydroxide Pellets are used to saponify fats and oils to create soap.
  • Sodium Hydroxide can come in pellets or flake form
  • Sodium Hydroxide flakes are preferred to pellets as it do not cling to you and your tools due to static electricity
  • Sodium Hydroxide is extremely hygroscopic (attracts moisture) and needs to be kept in a sealed container in a cool dry place. If left out, it can attract enough moisture from the air to turn completely liquid!

In case you are not aware Sodium Hydroxide (NaOH), also known as lye, is an essential ingredient in the soap making process. When sodium hydroxide pellets (also know as beads) or flakes are mixed with a liquid, a lye solution is created. This solution, when mixed with fats and oils, will cause a chemical reaction called saponification. The result of saponification is beautiful handmade soap. Sodium Hydroxide can come in either pellets (or beads) form or flake forms.

Sodium Hydroxide is also known as lye and caustic soda. Chemically, it is an inorganic compound with a formula NaOH (the compound consisting of sodium cations Na+ and hydroxide anions OH−) [1] Pure sodium hydroxide is highly soluble in water but has a lower solubility in ethanol and methanol.

Sodium Hydroxide Pellets vs Flakes?

Both sodium hydroxide pellets and flakes are the same Lye but in different form. There is always a debate among soap makers on whether Sodium Hydroxide Pellets or Sodium Hydroxide Flakes are superior to one other but personally I prefer Sodium Hydroxide Flakes as Sodium Hydroxide Pellets tends to cling onto you or your tools due to static. This can be a problem as we do not want any residual lye to be clinging onto you when you move away from your soaping area.  So are Sodium Hydroxide Pellets and Sodium Hydroxide Flakes the same? Yes, they are effectively the same ingredient i.e. Sodium Hydroxide, but just in different physical form.

Note of precaution: ALWAYS pour lye slowly in small moderate amount into water, NEVER the other way round. Adding water to lye can cause a volcano-like reaction. No matter whether you are using Sodium Hydroxide Pellets or Sodium Hydroxide Flakes.
