Description

Aluminum Sesquichlorohydrate is a high-purity inorganic salt widely recognized for its efficacy as a primary active ingredient in antiperspirant formulations. Its importance lies in its ability to form temporary, comfortable plugs in sweat ducts, effectively reducing perspiration without causing skin irritation. This compound is essential for manufacturers in the personal care and cosmetic industries, particularly for producing roll-ons, sticks, sprays, and creams. Its reliable performance and compatibility make it a cornerstone material for global brands seeking advanced sweat control solutions.

Application

• Antiperspirant Actives: The primary application is as the active ingredient in a wide range of underarm antiperspirant products, including sticks, roll-ons, sprays, and creams.
• Personal Care Formulations: Used in deodorant body sprays, foot powders, and other topical applications where sweat reduction and odor control are desired.
• Cosmetic Grade Products: Incorporated into specialty cosmetic formulations that require mild astringent or sweat-inhibiting properties.
• Industrial Processes: Serves as a precursor or intermediate in certain chemical synthesis and water treatment processes where its aluminum content is utilized.
• Pharmaceutical Preparations: May be used in specific topical pharmaceutical applications requiring mild antiperspirant or astringent effects.
• Research & Development: Employed in laboratories for developing new personal care actives, studying metal-organic interactions, and material science research.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and handling.
