คำถาม

I am using a formula from the website linked here [url=http://www.myskinrecipes.com/shop/%E0%B8%AA%E0%B8%A3%E0%B9%89%E0%B8%B2%E0%B8%87%E0%B9%80%E0%B8%99%E0%B8%B7%E0%B9%89%E0%B8%AD%E0%B9%80%E0%B8%88%E0%B8%A5-thickener/1129-paste-maker-ceteareth-25.html:2xe31ws0]Paste Maker[/url:2xe31ws0]. The formula provides ingredient amounts in percentages (%). When I convert these percentages to grams to make the product, I am not achieving the texture shown in the picture on the website. Could you please advise on how to correctly convert the percentage formula to grams and troubleshoot why the texture might be off when using Ceteareth-25?

Converting Percentage Formulas to Grams for Ceteareth-25

It sounds like you are having trouble achieving the desired texture when converting a formula using percentages to grams. While I cannot access the specific formula you linked, I can explain the general process for converting percentages to grams and provide guidance on using Ceteareth-25 (also known as Paste Maker).

To convert a formula from percentages (%) to grams (g), you first need to decide on the total weight of the batch you want to make. Let's call this the Total Batch Size.

Then, for each ingredient in the formula, you use this simple calculation:

Ingredient Weight (g) = (Ingredient Percentage / 100) * Total Batch Size (g)

Example:

Let's say a formula calls for 5% Ceteareth-25, and you want to make a total batch of 100 grams.

  • Ceteareth-25 weight = (5 / 100) * 100 g = 5 g

If you wanted to make a total batch of 50 grams instead:

  • Ceteareth-25 weight = (5 / 100) * 50 g = 2.5 g

So, the amount in grams depends entirely on the total amount you plan to make.

Ceteareth-25 is used as an emulsifier and thickener to build texture and give weight to formulations. According to the product information, the recommended usage rate for Ceteareth-25 is 0.5% to 30%.

If you are not getting the desired texture, you might need to adjust the percentage of Ceteareth-25 within this recommended range. A higher percentage will generally result in a thicker texture. You may need to experiment by making small test batches, starting with a percentage in the middle of the range (e.g., 5-10%) and increasing or decreasing it gradually until you achieve the consistency you want.

Remember to accurately weigh all your ingredients using a scale for best results when working with grams.
