  • @Abdullah - crystallization temperature depends on the c-chain cut of the product. Normally it is mentioned in the product specification or technical data. The higher the C12 content the higher the crystallization temp. Common grades with a share of…
  • @fazalatif - you may try the following: A 15.0 % Ceteareth-20 20.0 % PEG-7 Glyceryl Cocoate 5.0 % Dicaprylyl Ether B 5.0 % Propylene Glycol add 100 % Water C x % Fragrance (your choice) x % suitable preservative ( Heat A and B separately up to 85°C …

  • If I am not mistaken in such case a SLS solution should be the better choice. Because the "gas release" is linked to the drying of the SLS. But SLS solutions are not the easiest to deal with. You need to protect them from too cold temperat…
  • @Tyss - correct. Try to lower your total salt content. This will very likely result in a reduced viscosity of your formulation. To compensate this viscosity loss you shall use another, salt free thickener - e.g. the mentioned Crothix Liquid. Alterna…
  • @ketchito - thanks for sharing the link. Interesting information! I have mainly experience with the mentioned Euperlan PCO and there I used it with similar electrolyte concentartions without any issue - even with benzoic acid preservation at pH 4.5 …
  • @ketchito - the electrolyte content of this formlulation should not be critical for a Styrene Acrylates Copolymer.  @Tyss - I can imagine that the incorporation of the opacifyer might have not been homogeneous enough. If it shall not be dispersed ev…
  • @vhogiono - try looking for Euperlan PCO. It is a Styrene/Acrylates Copolymer combined with a share of surfactant making it easier to dispers. It does not require a stabilizer in a formulation and definitely gives you the milk effect. No pearlshine …
  • @Abdullah - that's an unavoidable issue linked to the manufacturing of the SLS granulate. To make this easier to deal with a first pH adjustment should be done right at the beginning with only the SLS in water. Then you will have the lowest possible…
  • What you describe is normal for these surfactants / surfactant mixtures. No need to worry.

Please note that Iscotrizinol (alias Uvasorb HEB) is described as UVB absorber with some capacity in the UVA area. Most effective and stable UVA absorber is DHHB (Diethylamino Hydroxybenzoyl Hexyl Benzoate, alias Uvinul A Plus) - bu…
  • Hi Jason, A few things come to my mind when reading your summary. -> It is good to premix the powder polymers with Glycerin. However, instead of adding water to this premix you need to add this premix to the water (while stirring) and allow time…
  • Regulatory approved UV filters are safe to use also by pregnant women. But you will need to check which filters are okay to use in the region where you want to bring your product to the market. I would recommend connecting to a supplier of UV filte…
