Today I am going to briefly talk about the difference between pressed and poured shampoo and conditioner bars. If you have been making solid syndet shampoo and conditioner, you know it can either be pressed or poured. The formula can be the same or somewhat different, depending on the methods and other criteria. For those who have never made syndet shampoo and conditioner bars before, when I said poured, it means that the liquid mixture is poured into a silicone mold whereas a pressed method means the mixture is pressed using a puck mold / moon cake mold or something similar.
Here, I am just going to address the method and physical differences of the bars.
For shampoo bar, personally, I found it is much easier and convenient to press. The processing method is faster compared to the poured method. It gives a firm bar depending on how hard you can press the bar or whether you are using your hands or a machine.
For conditioner bar, I prefer the pouring method instead of press simply because it gives a smoother looking bar. You can definitely use the same formula to press the conditioner bar, however, it takes slightly longer to make.
Below is the comparison table for a better understanding.
Have you tried them, and what is your preference?
