Locron P, Locron P (Archroma), Aluminum Chlorohydrate, Dialuminium Chloride Pentahydroxide, 1327-41-9, 12042-91-0

The CAS number 12042-91-0 corresponds to Dialuminium chloride pentahydroxide, also known as Aluminum chlorohydrate2. This compound is commonly used in cosmetics, particularly in antiperspirants and deodorants, due to its ability to temporarily block sweat glands and reduce perspiration

Here are the physical and chemical properties of aluminum chlorohydrate:

Physical Properties

• Chemical Formula: Al₂Cl(OH)₅

• Appearance: White crystals or colorless liquid

• Density: 1.33 g/cm³

• Melting Point: 83-86°C

• Solubility: Soluble in water, alcohol, and glycerin

Chemical Properties

• Molecular Weight: 174.45 g/mol

• pH: 4.0-4.4 (in 10% aqueous solution)

• Reactivity: Aluminum chlorohydrate reacts with water to form aluminum hydroxide and hydrochloric acid. This reaction is significant in its use in water treatment and deodorant products.

Aluminum chlorohydrate has a variety of uses beyond its common application in deodorants and antiperspirants:

1. Water Treatment: It is used as a coagulant in water and wastewater treatment processes to remove dissolved organic matter and colloidal particles.

2. Cosmetics: Besides antiperspirants, it is found in some skin care products targeting specific concerns like acne and excess oil.

3. Industrial Applications: It is used in the industrial sector for its stability and adsorption capabilities. For example, it is used in some laundry detergents to help remove dirt and stains.

4. Swimming Pool Treatments: It helps control algae growth in swimming pools

There are several alternatives to aluminum chlorohydrate in cosmetics, especially for those looking for natural or less irritating options. Here are some common alternatives:

1. Sodium Bicarbonate (Baking Soda): Often used in natural deodorants for its odor-neutralizing properties.

2. Zinc Oxide: Known for its antimicrobial properties and is often used in sunscreens and diaper rash creams.

3. Magnesium Hydroxide: A gentle alternative that helps neutralize odor without blocking sweat glands.

4. Kaolin Clay: Absorbs moisture and helps control odor.

5. Vegetable Oils: Such as coconut oil and castor oil, which have natural antibacterial properties.

6. Essential Oils: Like tea tree oil, lavender oil, and thyme oil, which provide a pleasant scent and have antimicrobial properties
