HOW THEY WORK
Each of the three lip materials have different ingredients that assist in keeping lips hydrated. The Neutrogena MoistureSmooth Color Stick (lipstick) contains fruit extracts, mango, shea butter, and waxes to instantly preserve and add moisture to the lips. The Neutrogena MoistureShine (lip gloss) has a conditioning formula with a triple berry antioxidant complex-including Acai, Goji, and Aronia berries that improve the softness and smoothness of the lips. The Neutrogena Revitalizing Lip Balm includes stearic acid and SPF 20 to keep the lips protected and healthy. All three of them contain petrolatum, or petroleum jelly; the lip balm and lipstick both contain hydrogenated polyisobutene; and the lipstick and lip balm contain silica, which all contribute to keeping the lips moisturized.
The lipstick contains Malonaldehyde hydrate, with an atomic mass of 90.078. The entire lipstick has an atomic mass of 769.178, which means the hydrate has the percent composition of 11.71% in the lipsticks atomic mass, to create a more hydrated lipstick that can be applied and malleable, but won’t become entirely mushy and wet in texture.
The lip gloss contains Ethanoic anhydride, which has an atomic mass of 102.89, and the entire lip gloss has an atomic mass of 456.796, making the anhydride 22.34% of the composition. An anhydride is a molecule that has had water removed from it, so the lip gloss will gain mass when it reaches moisture on the lips, and the lack of water in the anhydride confirms the components of the lip gloss are not dissolved or diluted, (Percent Composition)Petrolatum is a nonpolar molecule of hydrocarbons that break easily, so as to apply well and keep smooth, while not being watery.

HOW CHEMICALS AFFECT THE PROPERTIES OF LIP MATERIAL
“When a woman wears lipstick, she may swallow a little of it, but it can also be absorbed through the lining of the mouth and it is estimated that a woman may ingest more than four pounds of lipstick in her lifetime.”
It is, “found that 28 per cent contained ingredients associated with cancer risk, such as butylated hydroxytoluene (BHT), nylon-6, ferric red (iron) oxide, polyethylene, and titanium dioxide.”
