Aluminium Chlorohydrate (ACH) powder is widely used in antiperspirants and personal care products due to its ability to effectively control sweat and odor. Here's a summary of its applications in this field:

1. Sweat Reduction:

   • ACH powder is the active ingredient in antiperspirants, where it works by forming a temporary barrier over sweat glands. This reduces the amount of sweat reaching the skin's surface without permanently blocking the glands. It is considered gentler than other aluminum salts, making it suitable for sensitive skin.

2. Odor Control:

   • By reducing sweat production, ACH powder also helps prevent body odor, as less moisture means fewer bacteria can thrive, minimizing the breakdown of sweat into malodorous compounds.

3. Formulation Versatility:

   • ACH powder is highly soluble in water, allowing it to be incorporated into a wide range of personal care formulations, including:
     • Roll-ons
     • Sticks
     • Creams
     • Sprays
     • Gels
   • Its powder form offers easy handling, stable shelf life, and flexibility in product development, making it ideal for formulating different product types.

4. Skin-Friendly Properties:

   • Compared to other aluminum compounds (like aluminum chloride), ACH powder is less irritating to the skin. This makes it a preferred choice in products designed for individuals with sensitive skin or for daily use.

5. Astringent Action:

   • ACH powder also acts as an astringent, helping to tighten the skin and reduce pore size temporarily, which contributes to the antiperspirant effect.

6. Regulatory Compliance:

   • ACH is widely accepted as safe for use in personal care products, and its inclusion at regulated levels ensures its efficacy without adverse effects.

ACH powder is a key ingredient in many personal care formulations, providing effective sweat and odor control while being gentle enough for regular use. Its solid form also offers flexibility in manufacturing and formulation processes.
