But what would cause the colour to fade? x
Waffle, you haven't explained it clearly on here but I assume when you say fading, you actually mean the colour fading and not just 'wearing off' at the free edge..?
To retain colour stabillty, special stablilisers are added to the majority of cosmetic products to prevent colours from changing and fading.
Unfortunely though, some pigments that are approved for cosmetics are more likely to fade than others. Therefore, just like when wearing nail polish or other cosmetic products, some clients may experience slight fading when wearing some shellac colours.
Some colours have a greater tendency to fade than others. In general, lighter colours are less stable than darker colours.
Shellac is formulated with acetone soluble polymers which creates the tiny tunnels allowing it to be removed in 10 minutes. These tiny tunnels also make Shellac less chemically resistant than other more stronger products such as L+P and UV gel. Therefore some pigments in Shellac can be easily attacked by chemical exposure during daily activities such as cleaning, laundry, gardening, swimming, car washing, bathing etc...
Sun light exposure can also make colours fade faster. Heat and humidity can accelerate fading when combines with chemical or sunlight exposure.
We have had some very hot and nice weather last week. I personally don't think it is just the one thing which has caused the fading, I think it could be the combination of several things together - chemicals, heat and UV exposure.
I am not quoting that CND Shellac has a major problem with colour fading, as yet, I myself is still to meet a client whose Shellac has faded. But I am aware of this possibility and
IF your clients are the very small minority who are experiencing fading problems, then these could be some of the causes to consider.
Hope this helps.
