Creating an Antiperspirant and Deodorant Spray

To create a concentrated antiperspirant and deodorant spray for underarms, you will need a few key components:

1. Antiperspirant Active: This is the ingredient that reduces sweating. A common and effective option is Anti-Sweat™ (Aluminum Chlorohydrate). This is a powder that can be incorporated into water or alcohol-based formulas.

2. Deodorant Active: These ingredients help to reduce body odor, often by inhibiting the bacteria that cause it. Options include LipidSoft™ Deo (Triethyl Citrate), DeoMax™ Liquid (from fruit tannin), or Odor-Kill DO™ (Octenidine HCl). Citromask™ is another natural deodorizer option.

3. Base/Solvent: For a spray, you need a liquid base that can dissolve the active ingredients and fragrance. Alcohol (Ethanol) is a common solvent. Dipropylene glycol is also suitable for dissolving fragrances and helps them last longer. Alternatively, you could use a ready-made base like 8 Hours Fragrance Spray Base (Musk-Free), which is designed for fragrance sprays and contains alcohol and glycols.

4. Fragrance: You can add fragrance to the base/solvent. Ensure the fragrance is compatible with the chosen base (e.g., oil-soluble fragrance in an oil/glycol base, or use a base designed for fragrances like the 8 Hours Fragrance Spray Base).

Formulation Approach:

A typical spray formula would involve dissolving the Anti-Sweat™ (if using) and deodorant actives in the chosen solvent base (Alcohol, Dipropylene Glycol, or 8 Hours Fragrance Spray Base). Then, the fragrance is added to this mixture. The concentration of Anti-Sweat™ should adhere to regulatory limits (e.g., up to 25% in the US, check local regulations).

For dissolving fragrance safely, using Dipropylene glycol or a base specifically designed for fragrances like 8 Hours Fragrance Spray Base (Musk-Free) is recommended as they are effective solvents for perfumes.

While Antiperspirant / Deodorant Base Cream is available, it is a cream format and not suitable for a spray. Isopropyl Myristate (Deodorized) is an oil that can be used in skincare but might not be the primary solvent for a clear spray base, and high concentrations can potentially clog pores.

Always ensure all ingredients are compatible and stable in your final formulation.
