Minimizing Yellow Stains in Dry Stick Antiperspirants with Aluminum Chlorohydrate

You've read correctly that yellow stains on clothing, particularly in the underarm area, are often linked to aluminum salts used in antiperspirant products. While many aluminum compounds can cause this issue, the good news is that it is possible to formulate a dry stick antiperspirant using Aluminum Chlorohydrate with minimal staining.

Aluminum Chlorohydrate and Staining:

Aluminum Chlorohydrate is recognized as one of the aluminum-based antiperspirant active ingredients that causes the least amount of yellow staining compared to other types. However, as the staff reply mentioned, it doesn't mean staining is impossible, especially when used at high concentrations or depending on individual body chemistry and laundry practices.

Using Anti-Sweat™ (Aluminum Chlorohydrate) in a Dry Stick:

Yes, you can use Anti-Sweat™ (Aluminum Chlorohydrate) in a dry stick formulation. The product description for Anti-Sweat™ specifically mentions its suitability for anhydrous formulations like deodorant powders or roll-ons, which are similar in principle to dry sticks as they contain little to no water. The powder form of Anti-Sweat™ will not dissolve in the anhydrous base but will activate upon contact with sweat.

Maintaining Effectiveness and Minimizing Stains:

Using Anti-Sweat™ (Aluminum Chlorohydrate) at the recommended usage rate (typically up to 25% as per FDA guidelines) will provide effective sweat reduction. By choosing Aluminum Chlorohydrate over other aluminum salts, you are already taking the primary step to minimize yellow staining while maintaining antiperspirant efficacy. To further minimize potential staining, ensure the product is applied thinly and allowed to dry before dressing.

Consider using an anhydrous base specifically designed for antiperspirants, such as the Antiperspirant / Deodorant Base Cream, which is formulated to be compatible with aluminum-based active ingredients like Aluminum Chlorohydrate.

In summary, using Anti-Sweat™ (Aluminum Chlorohydrate) in a dry stick formulation is feasible and is the best option among aluminum salts for minimizing yellow stains while effectively reducing sweat.
