先說這是個很簡易的公式,並且是純數學的計算,並沒有把化學方面的狀況考慮進去~
例如有些精油體積較大、稠度較高或是化學分子在接合後會有不同…這些我並不理解,所以只能做到數字上的計算orz
不過,如果你跟我一樣沒有很講究的話,這個公式能頂著用,誤差應該不算太大XD
以上說明完畢,公式如下:
要添加的精油量(ml)=基底油ml×想要的%數÷(1-想要的%數)
知道要添加的精油量之後,只要乘以15或20就可以知道要幾滴了:乘以15的狀況適用於較濃稠(大滴)的精油,乘以20的狀況適用於比較水(小滴)的精油,大家請自行斟酌
以15ml基底油、想添加4%濃度的精油進去為例:
15ml×4%÷(1-4%)=15ml×0.04÷0.96=0.625ml
接著再假設是要添加比較水的精油,公式就會是0.625×20=12.5,所以要加12.5滴
(那個0.5大家就自己斟酌吧,總之12~13差不多)
這幾天為了調油濃度問題,殺死不少腦細胞XDD好不容易才回想起國中的一元一次方程式……(真的是加減乘除之外全還給老師了)
希望這個公式可以幫大家省一點腦細胞囉!
