Reducing Cost Without Losing Character: Study Guide

Read our guide to reducing formula cost, then cut one formula by a stated target, test each change blind and record what the savings really cost in odor.

Professional 15 min study By the RUŌOD Lab team Updated

In short

To reduce a formula's cost without losing its character, begin with the lines that contribute most to cost, change one at a time, and test each change blind against the original. The guide lists the common routes. Here you do it to a real formula, with a target, so you can see what savings actually cost in odor.

What you will learn

  • Target the lines that drive cost
  • Test whether a saving can be perceived

Before this lesson: Calculating Formula Cost: Study Guide

What to look for as you read

  • The difference between replacing, reducing and restructuring a material.
  • Which savings disappear on a real supplier's pack sizes.
  • Which later checks a cost change sets off.

Practical exercise: Cut 20% from one formula

About 90 minutes · You will have: a costed, blind-tested version of a formula at about 20% less cost

  1. Take the formula you costed in the previous guide. Set a target of about 20% less.
  2. List its top three cost contributors, and for each, write one way to reduce it.
  3. Make one version per change, and cost each one.
  4. Compare each blind against the original at 15 minutes, 2 hours and 8 hours.
  5. Combine the changes you could not detect, and test the result again. Small changes can add up.
  6. Recheck restrictions and allergens for what changed.

You have done this well if you reach the target or can say why you can't, each saving has a test behind it, and you can state what was lost. "Nothing perceptible to me, on strips, over 8 hours" is an honest finding. "No change" is too broad.

Knowledge check

1. Where should you look first to reduce cost?
Show the answer

The lines with the largest cost contribution. Saving a tenth on a large contributor beats removing a cheap line altogether.

2. How do you know a cheaper version still works?
Show the answer

Blind comparison with the original, at several times. A side-by-side blind test is the fair check. Include the drydown.

3. After swapping a material, what else must you recheck?
Show the answer

Restrictions, allergens and stability. A new material brings new constituents and new behavior.
