How can a washing powder enzyme be used to remove stains most effectively?
Enzymes
Lipase: Good at breaking down fats and oils. (Triglycerides)
Protease: Breaks down protein chains; good for removing protein stains.
Amylase: remove starch-based food stains. (Polysaccharides)
Cellulase: Effective at removing plant-based stains; such as grass stains. Also used to break down small cotton fibres that gather on clothing with use. Helps expose dirt and stains in order to make removal easier. (Cellulose)
Longevity of the enzyme; does its effectiveness at removing stains and dirt deteriorate with time? Do they need specific storage conditions?
Stains
What stains? Grass (what is making is stain?), food (what kind? Beetroot, tomato sauce), blood
pH of the stain: does it affect effectiveness of enzyme activity?
What makes a stain?
Caused by a chemical and/or physical reaction between two materials that are unlike each other.
Stains will bind to materials similar to their base. e.g. oil-based stains bind to oil-based fabrics
What material is stained?
Washing powder/detergent
Is the laundry detergent designed for a specific use? E.g. Is it stain removal? Specific stains? Is it oil-based stain remover, etc.?
What state does the detergent have to be in for the enzymes to work? Liquid, powder? Either?
How long does it take for the stain to be removed?
What are necessary and what are optional extras? E.g. Cellulase is useful, but can laundry detergent work without it?
Washing process
What temperature is it designed to be used at? Is it for cold wash or warm wash? Most washing machine run types are warm wash.
Hand washing? Hot water? Cold water? Harshness of hand washing vs washing machine?
Hot water or Cold water; optimal temperatures for enzyme activity would be best
Each enzyme has an optimal temperature to work at.
