Combining Ethylhexylglycerin and 1,2-Hexanediol for Body Odor Control

You are asking about the appropriate percentage of 1,2-Hexanediol to use when combining it with 1% Ethylhexylglycerin for body odor control.

Based on the product information:

• Ethylhexylglycerin is known for its deodorant properties and also acts as a preservative enhancer. The recommended usage rate for Ethylhexylglycerin is typically between 0.3% and 1.0%. Using 1% is within this recommended range.
• 1,2-Hexanediol is a versatile ingredient that functions as a solvent, humectant, and importantly, a preservative booster. While not classified as a preservative itself, it helps control microbial growth, which can contribute to body odor.

The product description for 1,2-Hexanediol suggests a usage rate of 3% when used as a preservative booster to enhance the effectiveness of other preservatives and help control germs. This germ-controlling property is relevant to managing odor-causing bacteria.

While 1,2-Hexanediol can contribute to odor control through its effect on bacteria and by boosting other ingredients, the optimal percentage specifically for enhancing the deodorant effect of Ethylhexylglycerin in your particular formulation is not explicitly defined. The ideal concentration can depend on the overall composition of your product and the desired level of efficacy.

As noted in the previous reply, effectively addressing significant body odor may require incorporating dedicated antiperspirant or deodorant active ingredients in your formulation.

If you choose to use 1,2-Hexanediol in your formula with 1% Ethylhexylglycerin, using it at around 3% could leverage its preservative boosting and germ-controlling benefits, which may assist in odor control, in addition to its other properties like humectancy and solvent action.
