    Double-check your glycerin as it could contain the impurity that turns pink when it comes into contact with an alkali, such as sodium hydroxide (NaOH).

    Exams?

    The molecule chloroethane, C2H5Cl, decomposes in the gas phase to
    ethylene, C2H4, and hydrogen chloride, HCl, gases according to the net reaction.

    C2H5Cl(g) → C2H4(g) + HCl(g)

    SB 312 refers to Annex III of the EU Cosmetics Regulation No. 1223/2009, so it stands to reason that declarations found on-pack for products sold in CA require the list of 26 quantified and declared at concentrations > 100ppm when present. Good times.

    @Mark - Can I trouble you to elaborate on the body cavity/510K comment? Are Vaginal rinses classified similarly? What about anal cleansers/wipes?

    @Microformulation - Thank you for the response.

    I understand reverse engineering is a relatively easy task for those skilled in the art and that marketing is king when it comes to garnering sales and market share. That aside, I’m simply looking to identify ways to safeguard my investment. 

    This particular house does extensive custom development work and manufactures a house PL-line. Given this, there may be a conflict of interest present and I’m looking for a mutually binding and commonly accepted framework to protect myself. By no means do I want to tie their hands but a competitor’s ability to market a mimic of my formulation would be diminished, if the house was prohibited from reproducing a similar design. 

    This request may seem to be bordering on paranoia but I’m not familiar with contract normalities for this type of work. I want to ensure that I can intelligently present a framework which suites to protect both parties when I come to the table. Perhaps I need to seek legal council for this? 

    Thanks again!
