    Hello

    Can CDEA be replaced by some other chemical? I found that it is deemed as unsafe, carcinogenic, and hence even banned in some places. FDA hasn’t declared it unsafe but cancer research institute has labelled it as a carcinogen.

    There isn’t any one-to-one replacement. We used Cocamidopropyl Betaine as a replacement but had to make significant adjustments to rest of the formula.

    Incidentally, the best science does not show Cocadmide DEA causes cancer and is safe to use in products at levels as used in cosmetics.

    Hello everyone,
    I want to know about the impact of perfumes on dish wash fromulation as i am facing to types:
    1 thickness decreasing
    2 Smell also drops by adding more surfactants(SLES or Labsa).
    Can somebody tell me about water based and oil based perfumes? 

    The perfume what I use in my dish wash , shop keeper call it ‘ Lemon 3 ‘ . I bought 1 litre but did’t see its lebel . It is water soluble , coz it finishing product remains transparent . 
    I add perfume befor adding CAPB and salt to thicken to avoid this theckening problem

    @Aanchal - We have replaced Cocamide DEA with Cocamide MEA with very little adjustment to the formula. It is the free DEA in the CDEA that is the issue with respect to carcinogenicity.

    Please stop spreading misinformation

    Cocamide DEA was never really proven to cause cancer by itself.
    Their findings couldn’t be readily replicated so its believed cancer was caused by a by-product, not CDEA itself.

    The Cancer Research Institute doesn’t test chemicals at all. They just fund some experimental therapy studies.

    The International Agency for Research on Cancer does test chemicals.
    For CDEA it 

    68603-42-9 Coconut oil diethanolamine condensate 2B 101 2013

    https://monographs.iarc.fr/list-of-classifications-volumes/
    Its monograph fits in the Group 2B: The agent is possibly carcinogenic to humans.

    There is limited evidence of carcinogenicity in humans and less than sufficient evidence in experimental animals. It may also be used if there is inadequate evidence in humans but sufficient evidence in experimental animals. Occasionally, an agent (or mixture) may be placed in group 2B if there is inadequate evidence in humans and less than sufficient evidence in experimental animals but there is supporting evidence of carcinogenicity from mechanistic and other relevant data. An agent or a mixture may also be classified in this category solely on the basis of strong evidence of carcinogenicity from mechanistic and other relevant data

    Ginko Biloba extract, Kava extract, magnetic fields, Medroxyprogesterone acetate, metronidazole, Nickel metallic and alloys, Oxazepam, Phenobarbital, Progestins, Radiofrequency electromagnetic fields, polygeenan (carrageenan derivative), goldenseal root powder belong to the same group, are widely used, some of them even taken by mouth, some are even FDA approved meds, and not proven to cause cancer.

    Thanks for your inputs. Glad that my doubt is cleared and nobody will be misinformed by my comment.

    CDEA is available in liquid form at most vendor’s. Can it be used in liquid state instead of solid? How?

    I have an idea wherby you can solublize menthol without solublizer. By adding menthol into warm water at 40 C.

    There are several sources to find example formulas, like UL Prospector, or formulation books.
