Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.
PEG-40 Hydrogenated Castor Oil helps ingredients to mix better. It has nice cleansing activity helping to remove sebum and dirt from the surface of your skin. It's also responsible for making soft foam in soaps, shower gels, etc. Despite it having "PEG" in the title, it's considered to be safe.

Phenoxyethanol
Roles: Fragrance, Preservative
Antiseptic
Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.
Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.
Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.
It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.

Linalool
Roles: Deodorant, Fragrance, Masking
Allergens
Linalool gives the product a nice and fresh lavender scent. It can be found in many essential oils. It oxidizes during air exposure and becomes allergenic. It can lead to irritation causing problems for people with sensitive skin. The threat is even higher if the product was opened several months ago. In such products, more Linalool is oxidized.
