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).

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

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

Panthenol:
D-panthenol = provitamin B5: Improves and increases the skin's ability to retain moisture, has an anti-inflammatory effect, reduces or inhibits itching. Stimulation of epithelialization: Small wounds (shaving), skin abrasions, blisters heal better. When used in hair care products, it is not only deposited on the hair and scalp, it also penetrates them and has a long-term effect. As pantothenic acid is an important component of healthy hair, the precursor D-panthenol serves as “food for the hair” according to scientific studies. It provides the hair with long-lasting moisture, improves the combability of the hair, reduces the formation of split ends, improves the condition of damaged hair, thickens the hair and gives it shine. The brittleness of fingernails is reduced.

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

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

D-alpha Tocopheryl Acetate:
Natural vitamin E acetate; storage form in the skin, is converted into the active form by dissolving the acetate bond; antioxidant with skin-protecting properties, e.g. against UV radiation, retains moisture, delays premature skin ageing

Biotin:
Vitamin H, important for the normal function of skin and hair

myo-Inositol:
A sugar-like growth substance that is widespread in the plant and animal kingdom and is part of the vitamin B complex. Hair loss is observed with a lack of myo-inositol.

Thymus Vulgaris Flower/Leaf Extract (and) Glycerin:
Herbal active ingredient, effective against hair loss, dandruff and greasy hair, not to be confused with thymus of animal origin (Thymus Glands Extract)!

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

Polysorbate 20:
Emulsifier for O/W systems, solubilizer, is obtained from sorbitol.

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