精油跟精华油的区别是什么?功效成分有哪些不同?
精华油和精油的浓度不一样,精华油的精油含量比较低通常在5%左右,精油是百分百提取。在使用方法上,精华油比较简单,使用完爽肤水后,取适量直接涂抹于面部,轻轻按摩吸收后,再使用其他的产品。
精油在使用之前需要稀释、调配,可以稀释在基础油、按摩膏、乳液等多种媒介中,多种单方精油调配后功效更甚于单独一种,选择哪种精油、搭配比较复杂。
正确使用精油则需要懂得很多的精油及芳香疗法的知识。精华油的功效就是用来护肤,精油则有多方面的功效,身体、心理、生理等多方面都可以通过不同的精油来实现相应的功效。精华油会与成套的护肤品一起使用,这样效果才会更显著,精油没有这样的要求。
Essential oils are mostly natural plant sources, divided into single essential oils and compound essential oils, the composition of the formula is relatively small; essential oils are in accordance with the actual skin feel and application requirements, more compounded with different esters, alkane oils, the composition of the formula is more complex, can be used directly skin care.
1.精油是从植物的花、叶、茎、根或果实中,通过蒸馏法、挤压法、冷浸法或溶剂提取法提炼萃取出来的挥发性芳香物质。成分复杂,主要是萜烯烃类、芳香烃类、醇类、醛类、酮类、醚类、酯类和酚类等。一般精油常用于芳疗,精油分为单方精油和复方精油。单方精油就是从某一种植物中提炼的精而根据一定比例混合多种单方精油则成了复方精油。精油分子非常小,渗透性好,但不能单独使用,必须稀释使用。如果直接用在肌肤上会造成刺激,引发过敏。
- 而精华油(也被成为面油、护肤油)是含多种脂溶性的功效性成分的油状精华,它的主要成分是一些天然油脂成分中所含的不饱和脂肪酸、神经酰胺、胆甾醇、各种维生素等。精华油是一种可直接使用的常规护肤品,主要作用是加强保湿、改善屏障功能、抗皱、滋润肌肤等。
- Essence generally refers to the water system, with a certain consistency of transparent viscous liquid, generally have anti-aging, firming, whitening and other effects. Essential oil is generally a pure oil system, generally have a repair, moisturizing, anti-wrinkle effect, the two systems are different, an oil soluble a water soluble, so there will be an oil a water difference in efficacy.
用精油取代香精进行调香,注意事项?
Essential oil ingredients are more complex than fragrances and require close attention to the impact on the system after addition. Most essential oils are plant-derived, which itself does not have a good mechanism to make the fragrance last, then, may be less lasting than synthetic fragrances.
1.不要将两种香薰精油倒入同一个容器中或摇晃,以免两种香薰精油混合后产生异味。
2. Do not mix more than two flavors.
3. Due to the long reaction time of the spice blend, the alcohol will dissolve more slowly. Sometimes, the top notes can be overwhelming. Be sure to let it sit for a while after spraying to allow the alcohol to evaporate before smelling.
4. The smell of essential oils is not self-determined, so avoid using them on your hair or parts that tend to sweat.
5如果是水剂的话,需要注意增溶剂比例是否合适,观察耐寒浊点是否变朦;还要多注意耐热,光照,是否会变淡,变味,变色等。
精油的留香短问题
精油如果是真的,那么它就是植物提取的油性成分,里面的香味本身就非常容易挥发,想用这个香味,那就只能对这个精油提前做包裹,让它不易挥发,可以做一些高压均质形成纳米乳液
可以采用定香比较优异的香精,比如微囊包裹的香精或者做过固定处理的香精,最好和香精供应商进行沟通,这类的香还是蛮多的。
可以采用微胶囊固定技术和纳米纤维素固定技术进行稳定化处理,增加持香度。
