Shower Gel comes in lots of different colours but why are all their foams always white?

Shower gel is basically just a detergent (like mild green Fairy Liquid!), and what a detergent does is to break down the surface tensions of water & oils to make them more "mixable", so you can wash away the grime.  In doing so, millions of tiny little bubbles form (plus of course bigger ones that you can see) and these bubbles have trapped air in them. All the little bubbles act as  reflecting surfaces, so since most of the light reaching them is white (from the sun or your light bulb) the reflected and scattered light coming back at you looks white.

I think the question is: Why is the perspiration stains yellow on a white shirt during the summertime?\n\nIt may be a chemical reaction to your deodorant or a medicine.

Maybe it is variety, lower cost, or maybe it could be that they had extra filters that they purchase and they are trying to lower their inventory levels a little to avoid from creating a large waste.\n\nI don't know what their plans are.   They may have had an excess in inventory of the tan filters so they thought why not use them and see if people likes the look of the tan filters better than the white filters.   They get to use up their inventory and plus get to try a market research experiment at the same time.

The dyes added to shampoos are usually only there at VERY low levels (typically less than 0.001%). When the shampoo foams, internal light reflection within the bubbles further reduces the apparent dye colour.\n\nIt is possible to produce coloured foams but the dye load needs to be increased dramatically (up to about 0.05%). The problem with this is there is then enough dye in the shampoo to actually stain. This level of dye is actually used in some high foam CAR shampoos because customers think that the colour strength is somehow related to the detergent strength (WRONG!).\n\nYou can also play some neat tricks with fluorescent dyes and optical brighteners - which activate ONLY when struck by UV light and so may be light in colour in the shampoo but higher in colour as they catch more light when dilute.

i'm assuming it's white just cause there is probably more sugar and sugar draws in moisture.

I don't think that's normal.  All the older girls I know have a full head of hair.  Some of them may turn white but they don't lose hair other than your normal hairfall in the shower.  You may have alopecia. Or it could be a symptom of something else. Go check with your doctor.

It's a cyst , my ex-husband has one as well.\nI bet the white stuff smells bad too. He can see a Dr. and they can remove it completely.

There are many reasons why a mineral might have a different streak color than its outward color. First, there are translucent minerals that are colored by trace elements. These minerals require a large amount of travel time for light to pick up the coloring effects of these trace elements. As a result, small crystals are typically paler than large crystals and extrapolating down to a speck of powder will remove all coloring effects of a trace element and result in a white streak. A translucent mineral that has variable colors will almost certainly have a white streak. \n\nSecondly, a mineral's structure and/or coatings can affect the outward color of a mineral and the streak in many ways is the true color of the mineral. Pyrite (known as "Fool's Gold") is always brassy yellow when found in crystals, even broken crystals, of any size; but when powdered, produces a black streak. It is the structure and chemistry of pyrite that produces the brassy yellow color, but only when enough structure is there. Gold's streak by the way is yellow! One note of caution, a streak plate is only about 6.5 in hardness and a mineral harder than 6.5 will not leave a streak on a streak plate but might scratch the plate leaving a white powder of porcelain, not the mineral! Fortunately most minerals harder than 6.5 have a white streak anyways.

Try using Intex. That is the actual manufacturer. To make sure check the bottom of the pool. There usually is the manufacturers name printed in white. I found the web site intexcorp.com

Sounds like you are talking about an anionic surfacant(a substance that allows things to get wet) There is a very popular material that does this it is called soap.

It's no use trying to find that out. Those conditions are to be fully controlled to get "non-colored" products.\nAnd be careful with what you use in food products!!

I think I heard this answered before somewhere. If I remember corretly it's that the amount of coloured pigment in the soap is tiny. When 'foamed up' the actual foam is only a few microns thick...so thin that the colour pigment (which was a small % in the first place) can't be seen?

If it doesn't have a bad smell it's nothing to worry about...I have the same problem sometimes. Here is from a site that tells what is going on...\n\n"You may very well notice a clear or white secretion at mid-cycle—this is an indication that you are ovulating"\n\nFrom: The tampax website (go figure! LOL)\nhttp://www.tampax.com/en_us/pages/wmn_main.shtml?pageid=AR0038

it's a mixture of air and water. when the waves are churning up they mix in air and the combination is what you see as foam. also some minor impurities are present.
