A common question from chemical manufacturers is whether cleaning-chemical development can qualify as research and development for the federal R&D tax credit under Section 41. The short answer is that cleaning-chemical development may constitute qualified research when the work evaluates alternative formulations to resolve a technical uncertainty about cleaning performance. Routine formulation using established recipes generally is not qualified research. This page explains the framework in general terms. It is educational and is not individualized advice. For the foundational framework, see our page on qualified research.
When Cleaning-Chemical Development May Warrant Review
Cleaning-chemical development may warrant review when the work involves a genuine technical uncertainty and a process of experimentation. Under the four-part test, the work must be for a permitted purpose, be technological in nature (relying on chemistry), be intended to eliminate uncertainty, and be conducted through a process of experimentation.
Common scenarios that may warrant review include:
- New formulation — evaluating alternative formulations to resolve uncertainty about whether a new cleaning chemical can achieve the required cleaning performance.
- New soil — testing alternative approaches to resolve uncertainty about whether a cleaning chemical can remove a new type of soil.
- New surface — evaluating alternative formulations to resolve uncertainty about whether a cleaning chemical can be used on a new surface without damage.
- Environmental — testing alternative approaches to resolve uncertainty about whether a cleaning chemical can achieve the required performance with improved environmental profile.
Routine Formulation vs. Development
A central distinction is between routine formulation and development:
- Routine formulation — formulating a cleaning chemical using an established recipe. There is no technical uncertainty. This is formulation, not research.
- Development — developing a new cleaning chemical where there is a technical uncertainty about whether the chemical can achieve the required performance, and evaluating alternatives to resolve that uncertainty. This may warrant review.
Hypothetical Example
Consider a manufacturer that is developing a new cleaning chemical for a new type of soil and is uncertain whether any available formulation can remove the soil without damaging the surface. The company evaluates alternative formulations, tests each, and systematically varies the approach to resolve the uncertainty. This systematic evaluation of alternatives may warrant review as qualified research.
By contrast, if the same manufacturer formulates a standard cleaning chemical using an established recipe, that is routine formulation, not research.
This example is illustrative only and does not state that the activity definitely qualifies.
Documentation That May Help
Records that can help support cleaning-chemical development claims include development records identifying the uncertainty and alternative formulations, cleaning-performance test results, and records of how results informed formulation changes.

Key Takeaway
Cleaning-chemical development may constitute qualified research when the work evaluates alternative formulations to resolve a technical uncertainty about cleaning performance. Routine formulation using established recipes generally is not qualified research. Because the distinction is fact-specific, professional review is appropriate before claiming the credit.
