In recent years, the development of detergents for manual dishwashing has evolved toward more complex formulas, not only from the perspective of cleaning efficacy but also regarding the care of the user’s skin. This trend has driven the incorporation of ingredients traditionally used in cosmetics, such as hydrolyzed proteins, botanical extracts, and natural emollients.
A pan-European survey on household cleaning product use revealed that only 18% of consumers regularly use gloves when handling kitchen cleaners, while 46% never use them. In Spain, the percentage of regular glove users is slightly higher, reaching 25%. The use of gloves during dishwashing is becoming less common, which directly exposes the skin to irritation caused by surfactants present in detergents.
Cosmetic Ingredients in Detergents
-
Hydrolyzed proteins (collagen, silk, oat): These compounds are used for their moisturizing and film-forming properties. By forming a protective layer on the skin, they minimize irritation caused by surfactants that are harsh to the skin, such as SLES (Sodium Laureth Sulfate). For example, hydrolyzed oat protein is common in “mild” dishwashing detergents due to its skin compatibility.
-
Botanical extracts: Plants such as calendula, aloe vera, chamomile, or green tea are incorporated for their anti-inflammatory, antioxidant, and soothing properties. These extracts reduce skin irritation and add marketing value by aligning with the demand for “natural” products.
-
Emollients and humectants: Ingredients such as glycerin, vegetable oils (almond, coconut), and derivatives like sorbitan esters are used to compensate for the lipid-stripping action of surfactants.
Market Examples
The incorporation of proteins and botanical extracts into dishwashing detergents represents a “cross-category” innovation, transferring benefits typical of the skincare sector to the home cleaning segment. In a context where gloves are no longer a usual part of domestic dishwashing, these formulations are becoming increasingly important.
