What Is Aluminum Dichlorohydrex Peg?
Aluminum Dichlorohydrex Peg is a complex formed by reacting polyethylene glycol with aluminum chloride hydroxide. The finished ingredient is an aluminum salt linked to short chains of ethylene oxide units, giving it a water friendly character that helps it blend smoothly into cosmetic bases. It originated in the late 1960s when formulators searched for milder alternatives to traditional aluminum chlorohydrate for underarm products. By attaching polyethylene glycol to the aluminum core they achieved a balance of strong sweat blocking power with lower risk of skin sting.
Production starts with pharmaceutical grade aluminum chloride hydroxide dissolved in purified water. Controlled amounts of polyethylene glycol are added and the mixture is heated so the two materials bond. After filtration and pH adjustment the slurry is spray dried into a fine, almost white powder that disperses quickly in both water and alcohol systems.
You will mainly find Aluminum Dichlorohydrex Peg in personal care products designed to manage moisture and odor such as deodorant sprays, roll on sticks, solid antiperspirants, foot sprays, body powders and some specialty hand creams for people who perspire heavily.
Aluminum Dichlorohydrex Peg’s Cosmetic Benefits/Uses
This multitasking ingredient contributes several helpful actions that improve daily personal care formulas
- Antiperspirant: Forms temporary plugs in the upper part of sweat glands which slow down the flow of perspiration so underarms and other areas stay drier for longer periods
- Astringent: Gently tightens skin proteins giving a fresh dry feel while also helping reduce the appearance of enlarged pores
- Deodorant: Limits the growth of odor causing bacteria which means less body odor even on busy days
Who Can Use Aluminum Dichlorohydrex Peg
Aluminum Dichlorohydrex Peg suits most normal, oily and combination skin types that need moisture and odor control. Dry or very sensitive skin may find it a bit tight or stinging because of its astringent nature, especially if applied on freshly shaved or irritated areas. People with eczema or compromised skin barriers should approach with caution and may prefer gentler options.
The compound is produced from mineral salts and synthetic polyethylene glycol so it is considered vegan and vegetarian friendly. No animal derived substances are involved in its standard manufacture, though finished products could contain other ingredients of animal origin so label checks are wise.
Regulatory bodies regard topical aluminum antiperspirants as safe for use during pregnancy and breastfeeding because skin absorption is very low, yet this is not medical advice. Expectant or nursing mothers should review any underarm product with their physician to be on the safe side.
Aluminum Dichlorohydrex Peg is not known to cause photosensitivity, meaning it will not make skin more prone to sunburn. It also plays well with everyday skincare actives like niacinamide and panthenol, making it easy to slot into most routines.
Potential Side Effects/Adverse Reactions
Reactions to topical Aluminum Dichlorohydrex Peg differ from person to person. The points below outline potential side effects yet most users experience none of these when the ingredient is properly formulated and applied.
- Mild stinging or burning on application, especially on freshly shaved or broken skin
- Redness or irritation in individuals with very sensitive skin
- Allergic contact dermatitis in rare cases
- Folliculitis or inflamed hair follicles if residue accumulates in pores
- Excessive dryness or flaking with overuse
- White or yellow stains on fabrics where product builds up
If you experience persistent discomfort or any concerning reaction discontinue use and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 1 / 5
Aluminum Dichlorohydrex Peg is highly water soluble, leaves little oily residue and is normally used at fairly low levels, so it has minimal tendency to sit inside pores and block them. Because it is an astringent it may actually help keep the skin surface drier, further lowering clogging potential.
That means it is generally suitable for people who are prone to acne or breakouts.
Very occlusive waxes or heavy emollients sometimes accompany antiperspirant actives in stick formats, which could raise the overall comedogenicity of the finished product, so the full ingredient list still matters.
Summary
Aluminum Dichlorohydrex Peg works as an antiperspirant, astringent and deodorant by forming temporary plugs in sweat ducts, lightly tightening skin proteins and limiting odor causing bacteria. Its PEG component helps it dissolve quickly in both water and alcohol bases which makes formulating easier and cuts down on tacky residue.
While it is not as famous as classic aluminum chlorohydrate you will find it in a solid niche of modern roll ons, aerosols and clinical strength sticks thanks to its balance of effectiveness and mildness.
Current safety reviews rate topical use as low risk because skin absorption is minimal and irritation is uncommon, yet everyone’s skin is unique so doing a small patch test when trying any new product is the smartest approach.
