    initial v1  
    771. Create all the blend ingredient chemicals in the usual manner. Introduce them if necessary.
    882. In the Chemical main menu, select ''Blend ingredients'' and click ''Add Blend Ingredient''
    9 3. You will see two drop-down lists labelled ''Chemical'' and ''Ingredient''. This is where you select the blend chemical, one of the ingredients and enter the precise proportion of the ingredient within the blend.
     93. You will see two drop-down lists labelled ''Chemical'' and ''Ingredient''. This is where you select the blend chemical and one of the ingredients. Enter the precise proportion of the ingredient within the blend.
    10104. Click [Save] and repeat until the blend is ready for use.
    1111
    12 If you haven't created a blend chemical, click the green + plus-sign and give it a name which makes it obviously a blend. Perhaps "Blend No 5" for Chanel No. 5!
     12Note 1. If you haven't already created a blend chemical, click the green + plus-sign and give it a name which makes it obviously a blend. You will have to enter the first few initial mandatory fields but nothing is significant because the software just uses it as a vehicle with a blend name to carry other ingredient (real) chemicals. Don't forget to [Save].

    1414=== Using a blend
    … …  
    17176. In the upper''Product'' drop-down list select the product which will contain the blend
    18187. In the lower ''Chemical'' drop-down list select the prepared blend chemical
    19 8. Enter the proportion of the blend in the product and click [Save] twice. First to get the blend saved in the database and secondly to process blend ingredient proportions after attaching them individually to the product.
     198. Enter the proportion of the blend in the product and click [Save] twice. First to get the blend saved in the database and secondly to attach all the prepared blend ingredients to the product and process ingredient proportions according to the blend proportion.

    21 Note 1. Blend proportion is used to not only calculate its ingredient proportions in the product but also to adjust ''Max end-use concentration'' of each chemical.
     21Note 2. Blend proportion is also used to adjust ''Max end-use concentration'' of each chemical.
    2222
    23 Note 2. You can add multiple prepared blends to a product. If the same chemical appears in more than one blend, it only gets added to the product once. Proportions and max concentrations are summed.
     23Note 3. You can add multiple prepared blends to a product. If the same chemical appears in more than one blend, it only gets added to the product once. Proportions and max concentrations are summed.
    2424
    25 Note 3. You can manually increase a blend chemical proportions and that will be respected because you know you have increased that part of the recipe
     25Note 4. You can manually increase a blend chemical proportions and that will be respected. If the summed blend chemical proportions are less than the existing proportion, the software assumes a human adjusted it upwards.
    2626
    27 Note 4. You cannot decrease a blend proportion (or summed proportion) calculated for an ingredient because it will be overwritten by the software to reflect its truth.
     27Note 5. You cannot decrease a blend proportion (or summed proportion) calculated for an ingredient because it will be overwritten by the software to reflect its truth.
     28
     29Note 6. You can optionally delete ''Product-chemical proportions'' blend records after their ingredients have been added. You can also leave them there for the record because they have no further effect beyond confirming calculations on each save. Deleting a ''Product-chemical proportions'' record does not delete either the Product or the Chemical.
