Aluminum Dichlorohydrate, also known as Aluminum Hydroxide Chloride (Al2(OH)4Cl2), is a chemical compound commonly used in the cosmetic industry. It is primarily sourced from aluminum, a naturally occurring element found in the Earth’s crust. This ingredient is often referred to by other names such as Aluminum Chlorohydrate or ACH.
The history of Aluminum Dichlorohydrate in cosmetics dates back several decades. Initially, it was introduced as an effective solution for controlling sweat and odor, making it a popular choice in antiperspirants and deodorants. Over time, its astringent properties were also recognized, leading to its inclusion in various skincare products aimed at tightening and toning the skin.
The production of Aluminum Dichlorohydrate involves a chemical reaction between aluminum chloride and aluminum hydroxide. This process results in a stable compound that can be easily incorporated into various formulations. The end product is a fine, white powder that dissolves readily in water, making it versatile for use in both liquid and solid cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Aluminum Dichlorohydrate:
One of the primary uses of Aluminum Dichlorohydrate in cosmetics is as an antiperspirant. This means it helps to reduce sweating 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 surface. This is particularly beneficial for individuals who experience excessive sweating, providing them with a more comfortable and dry feeling throughout the day.
Aluminum Dichlorohydrate also functions as an astringent. In simple terms, an astringent is a substance that causes the contraction of skin cells and other body tissues. When used in skincare products, it helps to tighten the skin and reduce the appearance of pores. This can lead to a smoother, more refined skin texture, making it a popular ingredient in products aimed at improving skin appearance and feel.
Another significant benefit of Aluminum Dichlorohydrate is its use as a deodorant. It helps to control body odor by inhibiting the growth of bacteria that cause unpleasant smells. By reducing the bacteria population on the skin, it helps to keep you smelling fresh for longer periods. This makes it a key ingredient in many deodorant products, ensuring that users can go about their day with confidence.
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).
Aluminum Dichlorohydrate is generally considered safe for topical use in cosmetic products. However, like any ingredient, it can cause side effects in some individuals. The potential side effects of topical application of this ingredient include:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Aluminum Dichlorohydrate during pregnancy 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.
Adverse reactions to Aluminum Dichlorohydrate are relatively uncommon, but they can occur. To minimize the risk of irritation or allergic reactions, it is recommended to perform a patch test before widespread usage.
The comedogenicity of Aluminum Dichlorohydrate is rated at 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means that it is unlikely to clog pores and cause acne or breakouts, making it generally suitable for individuals prone to blemishes.
