Hazelnut: This FO is the BEST!! Nice, very strong scent, very realistic. What a wonderful, warming, relaxing scent. Carries through well in MP, CP and HP. Our tester found that in CP it makes the soap quite dark .. like a cafe au lait colour .. or hot chocolate. No discoloration found in HP. Did not discolour M&P at all, although it made it a bit more cloudy (to a very minor extent). Flash point: 170F.
