    Do you mean that your product doesn’t make a dry skin soft and moist or you mean upon application it doesn’t feel moisturized and moist?

    If first one then the only two ingredients in your formula for that purpose is petrolatum and glycerin. I suggest 18% glycerine+ 5% petrolatum. That is enough in oil phase. Also as Graillotion said 1% dimethicone will help too. Mixing humectants is also better than one. I suggest add 2% lactic acid too and adjust pH.
    Adding vegetable oils like sesame oil without antioxidant is not a good idea.

    If second one then remember this. In o/w emulsion, water is your continues phase so your skin with first feel whatever is in that phase. Then every droplets of oil phase is surrounded by surfactants or emulsifiers so it is emulsifier that will contact your skin. Not the oils. So you will not see much difference between sesame oil vs olive oil in oil phase but you would see a huge difference if you use an emulsifier with oleic or behenic in it. So for feeling moisturized during application or shortly after use an emulsifier with oleic or behenic in it.

    About irritation, maybe it is rice but if irritation is not present from the first day then maybe your product is contaminated. 
    You don’t have a strong preservative specially for fungi.

    Looks like it has pH 14. 

    Before thickening it use it one or two time and see if your hands can tolerate it. 

    Or put it in a metal dish and see what happens. In my experience even metals dont tolerate pH 14.

    Those with higher molecular weight give higher viscosity. 

    A supplier suggested me 1.8 million Da at 0.1% but i didn’t purchase and use the product myself.

    ketchito said:

    @Abdullah By dry hair I was just referring to free water (there will always be some water within the cortex, but that’s bound water, and won’t act as solvent for actives). When hair loses lipids, it loses insulation, which means water exchange with the environment is more constant and dependent on factors like temperature. 

    Thanks

    Citric acid doesn’t have another function than lowering the pH. 

    What is the amount of each ingredient you use? 
    Maybe it is DEA

    @ketchito i was thinking hair is different from the skin. If it is dry, it meaans it lacks lipids, not water.

    What percentage of preservative did you use? 

    I suggest you use a blend that has parabens or IPBC in it witha a chelating agent.

    There are a lot of parabens or IPBC in phenoxyethanol products.

    @Abdullah No worries! So, conditioning agents to go where they’re supposed to go, need certain media (polar) to move and diffuse, and water is the perfect media…also, to keep both hair and conditioning agents in the right ionic state for deposition to occur. If your hair is dry, you won’t have this available (except for the water from your product and the one that is bound to the most external layer of your hair, which is barely enough). An exception to this are anhydrous oils, which composition is obviously water free (natural oils, esters, silicones) and whose coating function requires no charge interaction.

    Isn’t the water in conditioner enough? 

    Conditioners are more than 90% water.

    Paprik said:

    Well, that depends. In hair masks for very dry and damaged hair it is really beneficial. As it draws moisture to the porous and damaged/dry hair. Same as conditioner (it also prevents drying of the product), but it helps retain some of the moisture so the hair don’t get super dry after - Plus it fights frizziness. 

    In my (humble) opinion, it is good to have a good humectant in hair products. 

    And @Camel, yeah, 2% should be fine. Try it out and see. :)

    Thanks

    Also, you need some media to let conditioning agents diffuse…it’d be like trying to swim in a pool with no water (not sure this is a good analogy, though ????)

    @Paprik can you explain what is the benefit of humectant like glycerin for hair?

    In my opinion humectants attract water and we don’t want water in our hair.

    I am ready to change my opinion.

    Do you want slip during application or overall slip for hair? 

    If for during application then use some HEC. 

    If for overall slip then just use 4% BTMS-25, water and preservative. This will make a good conditioner.

    Non of your other ingredients will help the slip in anyway.

    Abdullah said:

    as Paprik said HEC don’t work with high surfactant specially glucoside. 

    Also if you dont have anionic surfactant it can not clean properly.

    While anionics are certainly the most effective when it comes to removing oils, I wouldn’t necessarily say that other surfactants don’t clean properly. I think you can achieve cleansers with amphoterics and nonionics that will be sufficient for majority of the population when it comes to cleanliness.

    They clean different soils and differently. 

    So they can be more drying but still dont clean properly.

    By proper clean i mean after some times you can feel it that your hair is not being cleaned no matter how many times you wash it.

    Perry said:

    @Abdullah - It wouldn’t be surprising that there was a recall even with a product that had a robust preservative system like you described. Cosmetics are not designed to be aseptic so even the best preservative system can fail. I would say most of the cause of recalls is due to inadequately clean manufacturing facilities

    I’d add that since a greater number of cosmetics that are produced use a good preservative system, you would expect more instances of recalls with good preservative systems than with bad.

    Thanks

    @Perry i did so. The problem is that when we search about ingredients of a recalled product in Google, it shows ingredients that they are currently using that may definitely be different and improved from the contaminated batch.

    I search ingredients of a recalled contaminated product and it had DMDM hydantoin, methyl & Propyl Paraben and EDTA in results from Google search.

    1: These ingredients are expensive. Each of these these ingredients can solve your problem alone. so why use all of them together and increase the cost and chance of adverse effect?

    2: these are hard to work with, solubilize and stabilize alone in a product. Mixing them will be harder.

    3. Using These will benefit you only if you have the problem. When the problem is solved, it is useless and waist of money.

    Yes it is completely safe. 

    What are the ingredients?

    so, won’t you have irritated and reddened skin after using a cosmetic with a pH of 3.5, twice a day for half a year?

    That depends on ingredients that you are using but suppose your ingredients work the same in each pH, a product with pH 3.5 will be better than 5.5

    Citric acid is also completely skin friendly. But lactic acid has extra benefits like exfoliation and skin hydration.

    Citric acid creates problems with cationic ingredients
