Ever wondered what makes your favorite deodorant so effective? Dive into the fascinating world of Aluminum Chlorohydrex PG and discover its crucial role in cosmetics, from its creation to its benefits and potential side effects.

What is Aluminum Chlorohydrex Pg?

Aluminum Chlorohydrex Pg, also known as 1,2-Propanediol, reaction products with aluminum chloride hydroxide (Al2Cl(OH)5), is a widely used ingredient in the cosmetic industry. This compound is often found in products designed for personal care, particularly those aimed at controlling sweat and body odor.

The history of Aluminum Chlorohydrex Pg in cosmetics dates back to the mid-20th century when the need for effective antiperspirants and deodorants became more pronounced. Scientists were on the lookout for compounds that could not only reduce perspiration but also minimize body odor. Aluminum salts, including Aluminum Chlorohydrex Pg, emerged as effective solutions due to their ability to temporarily block sweat glands and reduce moisture.

The production of Aluminum Chlorohydrex Pg involves a chemical reaction between aluminum chloride hydroxide and 1,2-propanediol (propylene glycol). This reaction results in a complex that combines the astringent properties of aluminum with the moisturizing and stabilizing benefits of propylene glycol. The final product is a stable, water-soluble compound that can be easily incorporated into various cosmetic formulations.

The Benefits/Uses of Aluminum Chlorohydrex Pg

In this section, we will delve into the officially recognized cosmetic benefits and uses of Aluminum Chlorohydrex Pg:


One of the primary benefits of Aluminum Chlorohydrex Pg is its function as an antiperspirant. This means it helps to reduce perspiration by temporarily blocking the sweat glands. When applied to the skin, it forms a gel-like plug in the sweat ducts, which reduces the amount of sweat that reaches the skin’s surface. This is particularly useful for individuals who experience excessive sweating, as it helps to keep them dry and comfortable throughout the day.


Aluminum Chlorohydrex Pg also acts as an astringent. In simple terms, an astringent is a substance that can cause the contraction of skin cells and other body tissues. This property helps to tighten the skin and reduce the appearance of pores. It can also help to dry out oily skin, making it a popular ingredient in products designed for those with oily or acne-prone skin.


Lastly, Aluminum Chlorohydrex Pg functions as a deodorant. This means it helps to control body odor by inhibiting the growth of bacteria that cause unpleasant smells. While it doesn’t stop sweating entirely, it does help to keep you smelling fresh by targeting the bacteria that thrive in moist environments. This makes it a key ingredient in many deodorant products.

Note: The listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Aluminum Chlorohydrex Pg is generally considered safe for topical use in cosmetic products. However, like any ingredient, it may cause side effects in some individuals. Here are some potential side effects of using products containing Aluminum Chlorohydrex Pg:

  • Skin irritation
  • Redness
  • Itching
  • Rash

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Aluminum Chlorohydrex Pg during pregnancy and breastfeeding are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.

While adverse reactions to Aluminum Chlorohydrex Pg are relatively uncommon, it is always prudent to conduct a patch test before widespread usage to ensure you do not have an adverse reaction.

In terms of comedogenicity, Aluminum Chlorohydrex Pg is rated as a 1 on a scale from 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating means it is unlikely to clog pores, making it generally suitable for individuals prone to acne, blemishes, or breakouts.
