means Lavender Water (Lavandula Angustifolia) if using Lavender Water (Lavandula Angustifolia) 90% In the formula, you don't need to include it. สารกันเสีย . that *If used as the main ingredient (over 60% of the recipe), no addition is required. สารกันเสีย in the recipe again because this ingredient contains สารกันเสีย from the manufacturer* (as Phenoxyethanol )

[quote="sunsleep0"]Then if mixed in DIwater must be mixed สารกันเสีย ?
is this Lavender Water The bottom line says Preserved by Phenoxyethanol 0.8% --> สารกันเสีย That's it. This translates simply as assuming Lavender Water ]. Lavender Water is 100% will have Phenoxyethanol At 0.8%, they say that if you use more than 60%, you don't have to add it. สารกันเสีย Again, compared to the 60% tri-syllable canonical, there will be Phenoxyethanol = 60 x 0.8 / 100 = 0.48% that Phenoxyethanol Approximately 0.5% in the formulation is sufficient to disinfect the formulation ( กันเสีย ) mixed in DI Water without Lavender Water will not have Phenoxyethanol also need to enter สารกันเสีย added eg Mild Preserved Eco etc. or reduce % of Lavender Water , but if it is above 60%, you don't need it. สารกันเสีย added.
