I thought the only function of Glycol Distearate is opacifier. It also helps silicone to deposit in the hair.

How about the shampoos that have silicone but no Glycol Distearate that are usually transparent, do they effectively deposit the silicone to the hair?

All I can say is: This may be the case for many people but, not for me. I look very carefully for styling products that give my hair a certain feel – Smooth, Dry and not too stiff. I have found (And LOST) several dozen over the last decade both from the drugstores and salons and most of the time it’s because they change the formula and ruin the hold or make it too stiff or ‘Sticky’

Again, while it may appear to you that the ONLY changes made were in the packaging, there are plenty of invisible changes of which you may be unaware.

For example, the styling polymer could’ve been changed by still maintain exactly the same chemical name. This would happen if they changed the ratio of monomers in their polymer. A change like this could significantly change the “stickiness” but not require an ingredient name change. It would be invisible to you.

Also, the fact that Pro-vitamins went lower on the label does not necessarily mean that they made any change at all. More likely, P&G tested the likability of ingredient listings and found that consumers liked the product better when Pro-vitamins are listed after fragrance. Ingredients are only required to be in order of concentration when the concentration is above 1%. In a styling product, neither fragrance nor vitamins are used over 1%.

The bottom line is that while the dimethicone could affect the “stickiness”, there are other, more scientifically likely, explanations.

The same with a pantene mousse and spray gel the ONLY changes were the packaging, the reduction of the ‘Pro-Vitamins’ (Now listed behind fragrance) and the addition of ‘Dimethicone’ the products went from a dry smooth feel to sticky and very ‘Un Comb-able’

I understand your position. All I can say is that yours is a single example and there may be other explanations. For instance, more changes (like source of styling resin, monomer ratio of styling polymer) could have been made of which you are unaware.

As cosmetic formulators, we add silicone to styling products for the reasons stated above.
