I stumbled across an ad for a clear, colorless lip balm that purportedly tints your lips a shade of pink determined by your skin's pH.
This balm stain applies on clear then reacts with your skin's pH levels, uniquely creating the perfect shade of pink lips just for you.
Out of curiosity (and the fact that I'm an easy target for marketing), I read further. The product contains the following ingredients:
- Hydrogenated Polyisobutene
- C12-15 Alkyl Benzoate
- Diisostearyl Malate
- Dibutyl Iauroylflutamide
- Dibutyl Ethylhexanoyl
- Thylhexanoyl Glutamide
- Isononyl Isononanoate
- CI 45410
- Chrysanthemum (a whole flower added to the bottom of the tube, presumably just to make it look nice.)
Other than CI 45410, I can't find anything on the above list that mentions anything about color -- and there's nothing listed that I think could change color based on pH.
Note: Some of the ingredients are very hard to find data for, but most seem to be thickening agents.
Does this clear lip gloss actually have the ability to change color based on pH or does the color come from the CI 45410? If it's from the CI 45410, what causes it to go from clear to pink?
