Annie was the first person who suggested silk soap to me, and it was like a thunderclap. I immediately wondered what rock I’d been living under for the past few years as it is such a brilliant idea (thanks, Annie!). So, silk soap has been on my to-do list ever since then, and I’m thrilled that I finally got around to making a batch.
With silk as the theme, I wanted these bars to be supremely luxurious. I was also leaning towards an Asian theme, inspired by the origins of silk. I decided on an unscented green tea and silk bar, though mandarin would be a great choice of an essential oil if you really want something scented. I was happy with the simplicity of an unscented bar, and I’ve found they come in handy as gifts for those who are scent adverse.
I used a green tea botanical extract as I have lots on hand, but you could use matcha powder, or swap the water in the recipe out for chilled and strained green tea (be sure to freeze half of it if you do this). My final soap ended up a creamy green shade, but all the edges that were exposed to air turned an interesting mottled brown. I’m not quite sure why this happened—I haven’t seen it in soaps made with liquid green tea, and since both the botanical extract and the silk are new soap ingredients for me, I can’t pin down the cause at this point. Input and opinions are welcome!
Green tea is loaded with antioxidants in the form of beneficial vitamins C & E, and it’s said to be a potent anti-aging ingredient to boot. Silk is a wonderfully versatile natural protein, it helps moisturize and protect hair and skin. It also lends a wonderfully silky feel to the soap, seriously amping up the luxury factor.

Use SoapCalc to calculate your final amounts of oils, lye, and water based on the size of batch you want to make. Unsure about how to use SoapCalc? I made a video to walk you through it! Please ensure you’re familiar with standard soap making procedure before diving in.
Follow my standard soap making instructions. Once you reach a medium trace, add the clay, green tea powder, and silk. Thoroughly blend with your immersion blender, and pour the soap batter into your mould.
Cover the mould and lightly insulate it. Let saponify for 24 hours before removing from the mould to slice. Age for at least 3–4 weeks before using.
