INCI - Full Breakdown
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.


Allantoin usually doesn’t catch too much attention, but it is an essential ingredient for sensitive, dry, and problem skin. It is a good moisturizer that makes skin hydrated. But manufacturers love it because of its strong soothing effect. It also exfoliates dead cells, stimulates recovery of your skin, and helps to protect the skin from the sun, frost, and similar negative impacts.
The component is researched very well and its soothing activity is confirmed by scientists. Used in concentration between 0.5-2%.

Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.
