I made my first batch of CP soap back in late September and let it cure for about 4 weeks. However, after I used it, my skin felt a bit itchy and dry. In addition, my bars of soap don't seem to last as long in comparision to a commercial soap (about a week or so). Has anybody else experienced these same issues? My recipe is a follows: castor oil (1oz), coconut oil (13oz), pomace olive oil (16oz), palm oil (8oz), lye 5.458 oz, water 12.54 oz. I also added 2oz of shea butter after trace, along with 1.5oz lavender essential oil and some lavender herbs. I noticed that most websites recommended distilled water while I admittingly used the poland spring bottled water. Could the the bottled water leave the batch a bit caustic? I also read somewhere that too much olive oil might cause the soap to shrink a lot faster while in use. Is this also true? Any suggestions and recommendations are welcome.
