Further explanations of the ingredients:

Aqua:
Water. It accounts for around 65% of the weight of the human body and is therefore of fundamental importance 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 in terms of quantity 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 spoilage of the product or dissolved salts that may impair the stability of emulsions or gels (sterilization and desalination).

Butylene Glycol:
Solvent with moisturizing effect on the skin, very good compatibility, should be preferred to propylene glycol in products used daily

Aluminum Lactate:
Mild, very well tolerated astringent, unlike other astringents it does not irritate the sweat glands. 

Triethyl Citrate:
Citric acid triethyl ester. Inhibits the growth of sweat-decomposing bacteria, very well tolerated by the skin, contained in many fruits.

Caprylyl/Capryl Glucoside:
An anionic surfactant and solubilizer; made from fatty alcohols and glucose of vegetable origin.

Salvia Officinalis Extract:
Sage extract: Has an astringent effect and stimulates blood circulation.

Lavandula Angustifolia Oil:
Lavender oil, essential oil with antiseptic effect, especially in combination with tea tree oil and manuka, e.g. for acne and athlete's foot, soothing and insect repellent 

Leptospermum Scoparium Branch/Leaf Oil:
Manuka oil, essential oil from the tea tree family with excellent antiseptic properties for acne and athlete's foot, especially in combination with lavender and tea tree oil

Melaleuca Alternifolia Oil:
Tea tree oil: Essential oil with a pronounced antiseptic effect, especially in combination with manuka and lavender.

Farnesol:
Dodecatrienol, essential oil, inhibits sweat-decomposing bacteria

Linalool:
Fragrance, natural component of essential oils.
