What is the concentration of active material in your SLS liquid?You may need to increase the amount of SLS in your formula. -
Formulas can definitely be used as a multi-use products but you need to consider what your formula can actually do and what your target market will accept.A shampoo/body wash/ hand wash product will probably be well accepted because these products already exist. If you develop the formula as a shampoo with some light conditioning this will also be acceptable as a body & hand wash.Trying to use a shampoo as a dish washing liquid might work but only to a limited extent as dish washing liquids are generally designed to cut through grease and you won’t get this performance with a well-formulated shampoo.A kitchen spray and wipe type cleaner is usually mildly alkaline and is developed for grease-cutting. Bathroom cleaners are often acidic to cut help remove soap scum. So neither would work particularly well in the other location. Also keep in mind that some natural stone surfaces in kitchens are sensitive to acidic cleaners.Hope this helps.

Is your serum water based?Dow and Lubrizol both have a number of a number polymer products that can assist in suspending beads.
-
I would be questioning where the Copper and Tin are coming from. What is in your formulation that could contain these metals as impurities?What is your pH? Metal ions can precipitate as hydroxides depending on the pH.You might get a better answer if you provide a list of the raw materials in your formula.

If it is derived from honey it is not considered vegan.
-
My guess would be that they are referring to it being a humectant.

The calculators and tables might look overwhelming but are pretty are easy to use. If you want an approximate value you can just look up the density that is closest to your value and then read off the concentration in %wt. Or you can use the calculators for a more precise value.In the case of a sodium hydroxide solution at 20oC with a density of 1.5, you can see from the tables that a density of 1.5 gives a concentration between 44 and 48% (closer to 48). The calculator determines that the concentration of sodium hydroxide is
47.31579% on a weight basis. This means that for every 100g of sodium hydroxide solution in your formula you would have 47.31579g of sodium hydroxide and the rest (52.68421g) would be water.For a potassium hydroxide solution with a density of 1.5 from the tables you can see that the concentration is between 48 and 50% (closer to 50%) and if you put some values in the calculator you can determine that a concentration of 49.8 %wt the density is 1.50007.Hope this helps. -
These tables and calculators will be useful to you.

I agree with Mark that you seem to have too little emulsifier.Also, what preservative are you using? Your fragrance/preservative level also seems high which may also contribute to instability.
-
According to this website (https://cosmetics.specialchem.com/product/i-lonza-honeyquat-50-pf) and my supplier Honeyquat has been discontinued by Lonza. As far as I am aware there is not another manufacturer so I would be probably look for a different raw material if you plan to make this formula again.
-
You seem to be using way to much sorbic acid and benzyl alcohol/dha.Your Xyliance emulsifer has a low electrolyte tolerance and many of your raw materials are considered electrolytes (e.g. aloe vera, citric acid etc) so try leaving these out or change to a different emulsifier.
-
As Pharma mentioned floor cleaners and hard surface cleaners usually have a high pH to help with cleaning.A pH of 8-9 is not considered high. As a comparison soap generally has a pH of 9-10 and is used on skin.
-
The low pH in combination with the moderate amount of ethanol is probably what is currently preserving your formula. If you increase the pH I would recommend adding a preservative.
-
What is the purpose of the sodium bicarbonate? It seems unnecessary.It is most likely that this formulation going to be irritating to skin/eyes because benzalkonium chloride is corrosive to skin and eyes at high concentrations. Your customers should not really be putting floor cleaner on their skin so there shouldn’t be a problem as long as the product is labelled correctly.

Check the use by date on your Microcount dipslides. They have a very short shelf life (<12 months).Maybe try testing some water/sample that you know is contaminated by bacteria to check if you can get any response from the dipslides.You could also try contacting Schulke as they have a microbiology lab and they might be able to test your water samples there as well.

This site has lots of information
21 CFR 701.3(b) and (p)
The ingredient declaration may appear on any information panel of the
package which is the outer container in form of a folding carton, box,
wrapper etc. if the immediate container is so packaged, or which is the
jar, bottle, box etc. if the immediate container is not
packaged in an outer container. It may also appear on a tag, tape or
card firmly affixed to a decorative or small size container.There are also exemptions for small pack sizes that allow for off label packaging but it requires leaflets be available the point of purchase.21 CFR 701.3(i)
The declaration of ingredients in labeling accompanying a cosmetic, i.e., off-package ingredient labeling, requires that:
(1)The product is not enclosed in an outer container,
(2)The total package surface area is less than 12 square inches, and
(3)The products are held for sale in tightly compartmented trays or racks.
The ingredient declaration must be in letters not less than 1/16 of
an inch in height and may appear on padded sheets, leaflets or similar
labeling accompanying the product.Products which are not eye or facial make-up
cosmetics or nail enamels must be displayed for sale in tightly
compartmented trays or racks of a display unit. The holder of the padded
sheets or leaflets bearing the ingredient declaration(s) must be
attached to the display unit.I think you will also find that Chapsticks are also considered drugs as they are marketed as skin protectants and sunscreens so the labelling requirements will be different. -
You will need to provide a list of ingredients for your soap base to get any real answers but you are probably destroying some of your soap based ingredients by acidifying them. Generally speaking soap + acid is not recommended as it reverses the saponification reaction.Perhaps the transparent soaps you saw were actually syndet bars.

It could also be the green tea in your PI blend that has discoloured.
-
Yes this is normal behaviour.Have a look at the table on page 6 of this document (http://www.timing-ouhan.com/images/lutensolxl.pdf) to see how different amounts of water change the viscosity of some BASF ethoxylated surfactants.
-
It is also possible that when you have scaled up you have also used a different batch of one of your raw materials and it is contaminated. You are using a number of natural materials (aloe vera, solagum tara and soy lecithin) which are all prone to microbial contamination.You will probably find a clause in the sales contract that they are not responsible for how you use the product or something similar.The best you could possibly hope for is for the manufacturer/supplier of the preservative to take back the unused product and refund you but even this is probably unlikely.
-
Yes you can use food grade dyes in cleaning products.I have never used E122 in a fabric softener so I have no idea of it’s stability but I have used FD&C Blue No.1 and it was stable in my formula.You might want to investigate the Milliken Liquitint dyes as these are often more stable than food grade dyes.
-
Just make sure if you are using two preservative blends that they don’t have the same components or if they do that you don’t exceed the maximum permissible concentrations for each individual component.
-
What dye are you using to colour the product?
-
Your preservative system has failed and to get a more helpful answer you will need to provide the formula.The Microcare SB preservative is based on organic acids and these acids are sensitive to pH so my initial thought would be that the pH is too high. Have you checked the pH?
-
@Pious None of the surfactants you have listed above (eg. Plantapon SF) are considered “organic” so you would not be able to make any claims regarding the product being organic. They are at best considered naturally derived.It would be best to check your local regulations about what natural claims are acceptable in your country.
