Hello
pentylene glycol has some properties that are better than
Butylene Glycol such as in the suspension / control of pathogens. It depends on the purpose of using
pentylene glycol in the formula you mentioned. For what purpose is it used in the formula? For example, if you choose to use it because it serves as
สารกันเสีย to avoid using
สารกันเสีย directly for gentle and safe skin. In this case, may choose to use
1,2-Hexanediol . Yes, but in other cases, for example, choose to use
pentylene glycol to act as a solvent for some of the ingredients in formula You may choose to use a glycol that can dissolve the active ingredients well, for example
Ethoxydiglycol instead.
