Manufactured soap

[Mike Dewhirst]

Previously, soap was just another chemical. The new (April 2024) Rules ease the way for two classes of saponification (soap) manufacture

1. Up to 10kg per year of a Listed fat or oil saponified with aqueous sodium or potassium hydroxide - Excluded "category", meaning of no interest to AICIS at all

2. Up to 100kg per year of any fat or oil saponified with aqueous sodium or potassium hydroxide - Exempted category, meaning AICIS is just as interested as with any other Exempted category chemical.

Other recipes or greater volumes need detailed categorisation as usual.

This ticket calls for a "Saponification of fat or oil with sodium or potassium hydroxide" selection plus other thingsnecessary for the software to identify the category without requiring all the chemical properties and hazards otherwise demanded.

Those other things include:

• identification of the ingredient fats/oils
• confirmation that saponification is done with sodium or potassium hydroxide
• checking that the chemical (soap) is Locally manufactured only
• up to 10kg of listed fat/oil being Excluded
• up to 100kg of any fat or oil being Exempted
• Post Introduction Declaration is not required
• Records need to be kept of the names of the fat or oil

[Mike Dewhirst]

• The actual chemical in soap has to be the oil or fat because the rules state "Listed" oil or fat at up to 10kg for it to be excluded.
• The saponification process presumably consumes the caustic solution.

To make Chemintro categorise soap correctly, the following needs to happen:

1. Add a new chemical, name the fat or oil and fill in the essential fields at the top of the page

2. Add the CAS number (if known) and save to establish if that fat or oil is Listed

3. Add product/chemical detail including proportion which defaults to 100% but may be less if you are going to include other ingredients such as fragrances etc

4. Click the yellow pencil (edit) icon which launches a pop-up window to name the product (Soap?) and choose the end-use (probably bath and shower products) and enter total product volume for this AICIS reporting period. Save to close the pop-up window and return to the chemical page.

5. In the Introduction section, Circumstances field select "Chemical (soap) saponification of fat or oil ..."

On saving, the software will determine if it is Excluded or Exempted or neither (>100kg)
