石油蜡在内的各种蜡经物理改性制成的一种含蜡含水的均匀流体，是由石蜡与几种不同种类、性能的乳化剂及适当的调节剂经乳化反应制成的固-油-水多相分散体系的稳定乳状液，一般根据用途选用所需石蜡及乳化剂的种类。中文名石蜡乳液外观灰白色均质半透明液体固含量30%；50%PH值7-9抗酸、抗碱、耐硬水、水溶性强、乳液稳定，任意比例水稀释不分层、不破乳、不结块、保质期长、固含量高、分散性好。石蜡乳液技术指标编辑1、外观：灰白色均质半透明液体；2、固含量：30%；50%3、PH值：7-94、稳定性：用特殊中性非离子乳化，避免以前用碱性皂化不稳定、易分层的缺点，密封放置阴凉处可以存放两年不分层、不破乳、不结块。[1]石蜡乳液应用领域编辑随着“绿色化学”新慨念的提出与实施，石蜡乳液的开发我利用越来越受到人们的关注。人们认识到以水代替有机溶液剂作为蜡制品的载体，可**减少对生态环境的危害，所以乳化蜡的开发和利用前景十分广阔。石蜡乳液皮革业石蜡乳液可与加脂剂复配在加脂剂中复配少量的石蜡乳液改善和提高加脂剂的效果，通过试验证明，向皮革加脂剂中复配1%～5%的蜡乳液，可提高加脂剂的填充性能，提高加脂剂在皮纤维中的渗透性能，增加皮革的防水性能。 STRAHL & PITSCH, INC. 石蜡Paraffin Wax,SP-1275, NF。河北销售白蜂蜡
一、石蜡的理化特性（一）石蜡是由于高分子碳氢化合物所构成，其结构式为CLH2n+2。含有16～35个碳原子的正烷烃，有少量的异构烷烃和环烷烃。为白色或黄色半透明无水的固体，无臭无味，呈中性反应。对酸和碱不易起反应，不溶于水，微溶于水，微溶于酒精、易溶于**、汽油、苯、煤油、氯仿等，在一般情况下不与氯化剂发生反应。（二）石蜡是石油的蒸镏产物，其溶点为30-70℃，沸点为350-360℃。。当石蜡加热到100℃或更高时，在与氧气充分接触的条件下，容易被空气中的氧气所氧化。医用的高纯度石蜡，其溶点为50-54℃其含油量。我国早已大量的生产高纯度医用石蜡，供医疗工作的需要。(三)石蜡的热容量大(见表)，导热性小(导热系数为)，比热为·度，为良好的带热体。由于其不含水分及其他液体物质，而且气体与水分不能透过，几乎不呈对流现象，因而有很大的蓄热性能。(四)石蜡加热后冷却时，能放出大量的热能(熔解热或凝固热)(见表)，每公斤熔解的石蜡变为固体时，放出的熔解热平均为39卡热量，即是熔解时的热量。熔解石蜡的温度愈高，由液体变为固体时的过程就愈慢，因而也就能较长地保持温热。(五)石蜡具有很大的可塑性，粘稠性和延伸性。随着热能的放散和冷却，石蜡逐渐变硬。上海史东毕斯小烛树蜡美国史东毕斯公司, 固体石蜡 Paraffin Wax, SP-1275P,NF.

Carnauba wax is considered among the hardest of natural waxes. It has a high melting point, enhances oil retention, produces a very durable film, is valued as a stable co-emulsifying agent and serves as an exceptional polishing aid.
Carnauba Wax is obtained from the leaves of the Brazilian palm tree known as ‘Copernica Cerifera’, also referred to as the "Tree of Life". The Carnauba palm flourishes in northeastern regions within Brazil, and proliferates naturally along riverbanks, streams and damp low-lands.
