Natural alkaline pH adjuster

Hello all,
      Would anybody suggest a alkaline natural buffer for pH adjustment? Natural extracts having alkaline pH are also acceptable. Product would be a natural hair colour.

Comments

  • This highly depends on the pH of your hair color. I experienced using Sodium Lactate - Lactic acid system. 
  • pH of finished product would be towards neutral side & after addition of all ingredients, pH was on acidic side so that how to increase towards neutral by using suitable natural buffer.

    Why would you consider sodium hydroxide unatural?

  • Look into Plantservative, even though its a preservative it has an extremely high pH naturally. Another option could be desadrops from Vevy Europe.

    pH is probably high because it has been adjusted by addition of base.
  • Thanks to all, product is in powder form & pH is towards acidic side (3-4) & to be raised towards neutral for which i need buffer. moreover its a natural based product (Natural hair dye)
  • Could try Sodium Citrate to get around pH 6.2
  • Why would you consider sodium hydroxide unatural?

    Curious about that as well... 
  • Sodium hydroxide is available in two forms flakes & pallets & my product is in powder form & moreover NaOH is hygroscopic which is a disaster for such a powder hair colour.

    I am having some difficulty understand this situation.  If your product is in powder form .... how can it possibly have a pH?

    It appears that your powder is mixed by the consumer in water to create the dye immediately before use?  If that is the case, why does it need to be buffered if it will be consumed in short order after mixing.

    Sodium Lactate is a liquid ... not feasible to use in a powder product unless you want the product to be some sort of paste.

    I think sodium citrate is your only option for a powder.

  • Thanks for suggestions, Let me explain first that finished product is in powder form which is to be mixed with water by consumer & apply on hairs (Powder hair colour). pH of solution of powder is acidic & desired pH to be on neutral to slightly basic side so that need a buffer in powder form to achieve neutral pH.
