Ingredients (INCI declaration of the ingredients):

Aqua, Alcohol, Isopropyl Alcohol, Lactic Acid, Aluminum Lactate, Eucalyptus Globulus Leaf Oil, Sodium Hydroxide

Further explanations of the ingredients:

Aqua:
Water. It makes up approximately 65% ​​of the weight of the human body and is therefore essential for bodily functions, including those of the skin. In many cosmetic products (aqueous solutions, cleansers, emulsions), water is the ingredient with the largest proportion of the formulation and forms the basis of the aqueous phase in emulsions. Water is a good solvent for polar (hydrophilic) substances such as alcohols, water-soluble vitamins, or salts. For use in cosmetic products, the water used is generally pre-treated to remove microorganisms that could lead to product spoilage or dissolved salts that might impair the stability of emulsions or gels (sterilization and desalination).

Alcohol:
Ethyl alcohol: Biocompatible. Has a refreshing and antibacterial effect. Also serves as a solvent for other ingredients. Contrary to other claims, there is no risk of a drying effect on the skin at normal concentrations!

Isopropyl Alcohol:
Isopropanol: Has a disinfectant effect like ethanol, but unlike ethanol, it also dissolves natural fats.

Lactic Acid:
Lactic acid. Occurs as a metabolic product in the body and on the skin; in higher concentrations and at a low pH value of 2 to 3, it has an exfoliating effect on the stratum corneum; in buffered form (physiological pH value of the skin approx. 5.5), it supports the moisture content and preserves the skin's acid mantle.

Aluminum Lactate:
Mild, very skin-friendly astringent, unlike other astringents does not irritate the sweat glands.

Eucalyptus Globulus Leaf Oil:
Eucalyptus oil: Antispasmodic, wound-healing, and stimulating. Antiseptic, recommended for inhalation in cases of respiratory illnesses.

Sodium Hydroxide:
Sodium hydroxide. Used to adjust the pH of cosmetic products. Sodium and hydroxide ions are identical to those found in the body.
