Phenolphthalein indicator spill onto skin
Didn't you receive the SDS for phenolphtalein (or its methanolic/ethanolic solutions)?
Weren't you given instructions on how to handle it?
Didn't you wear suitable gloves in addition to your safety goggles?


Back in the days, phenolphthalein was apparently used as a laxative. This is no longer recommended!

However, the current GHS classification is as follows:


  Germ cell mutagenicity, Category 2; H341
  Carcinogenicity, Category 1B; H350
  Reproductive toxicity, Category 2; H361f    


(cited from the GESTIS database)

To my knowledge, phenolphtalein is on the REACH Candidate list of SVHC (substances of very high concern) since 2011.

My suggestion is:


Contact a physician.
Report the exposition to your supervisors.
