Some of the banned ingredients are phthalates, parabens and surfactants. According to EWG's SkinDeep database, diethylhexyl phthalate is used in sunscreens, as well as moisturizers and lip balms with SPF in them. Many fragrance oils contain phthalates, as well, although I don't know if the phthalates in FOs are the same as any of the banned items.
If you use any surfactants or pre-made bases to make scrubs, lotions, lip balms, conditioners, syndet bars, etc., you need to check those ingredient lists carefully and frequently, because formulations do change.
California can be rather arbitrary about enforcing certain laws in certain situations. For makers who sell to anyone in California, that could require phthalate-free FOs in all body-care products (if the phthalates listed are actually used in FOs, which I don't know at this point).
Because this law only applies to "cosmetic products," actual soap would not come under this law. To qualify for the soap exception, the seller must avoid making any claims that would elevate the soap from "just soap" into a cosmetic product. Another good reason to learn the labeling laws well before thinking about selling!
You do have until 2025, fortunately, to comply with all of this.
