Some fragrance and essential oils are light or exceedingly strong in soap, so you can always use a little more or a little less to your preference. For instance, English Rose Fragrance Oil is very strong, so you don’t need to use a full 0.7 ounces per pound of soap to get a strong scent. Always adjust to your personal preference.
