Description

Our powdered Alum is Cosmetic Grade with USP / pHEur certification, specifically for cosmetics and other pharmaceutical uses. It is important to distinguish it from industrial alum (coarser, not fine), which is unsuitable because it contains heavy metals and its impurities are not filtered out.

Mineral Salt without toxic components.

Made up of potassium salts and aluminium sulphate, which is not absorbed through the skin because of its larger molecules and does not release aluminium itself.

Completely natural and very well tolerated by the skin.

It is a granular, white, loose, odourless powder that does not stain clothes.

Readily soluble in water, very soluble in boiling water, soluble in glycerol and practically insoluble in 96% ethanol.


Properties and Uses of Alum Powder

Widely used in deodorant products because of its antiseptic and antibacterial properties.

It does not block pores or prevent perspiration; it works by preventing bacterial proliferation.

It has been used as an aftershave treatment for centuries.

Ideal after shaving and hair removal because of its healing and soothing power. Mineral alum powder heals and disinfects any wounds that have occurred.

Also used to remove unwanted hair; repeated use over time tends to slow hair growth.

It is used in powders to treat excessive sweating of the feet and to improve cracked heels.

It can also be used as an exfoliant for acne-prone skin.

Excellent anti-wrinkle effect.

Its firming effect is also noteworthy.

It can be used to make deodorants, toothpastes, creams, soaps, exfoliants...



Recommended Dosage

Topical Use ; 0.5-5%.


Side Effects

  • At high doses, it is irritating and can be corrosive.
  • Systemic absorption of solutions used to irrigate the bladder can cause severe aluminium toxicity, including encephalopathy.

Precautions

  • Continued oral use is not recommended because it damages teeth.
  • Keep tightly closed, as exposure to air alters it and slowly converts it into basic aluminium sulphate.
  • Store in tightly closed containers protected from light.
  • Incompatible with borax, alkali hydroxides and carbonates, phosphates, calcium salts, lead salts, mercury salts, tannins, tartar emetic, astringent infusions and milk.
