Cleaning products
Also: cleaning agents, household cleaners, detergents
Products used to clean indoor surfaces, floors, bathrooms and glass — sprays, liquids, wipes and powders — considered here as a source of what they release into the air of the room while they are used and while they dry.
Why it matters indoors
Cleaning is one of the few indoor sources that is deliberate, repeated and concentrated in time. The release is short but intense, it happens in the room where someone is working, and it is often in a bathroom or a kitchen where the air is exchanged least. Solvents, fragrance compounds and the products of their reaction with indoor ozone all belong to this category.
What has been measured
In a French daycare study the measured compounds were grouped by statistical factor. The group described as indoor volatile organic compounds and aldehydes from cleaning products and personal care products was associated with ever wheeze treated with inhaled corticosteroids (odds ratio 1.22, 95 % CI 1.00–1.47), with odds ratios across all the outcomes examined ranging from 1.15 to 1.22 (F-0032).
The lower bound of that interval touches 1.00, which is the honest way to read it: the association was found, and it is not a strong one.

Each row is one Finding — a sentence as printed in one study, recorded with its page in the Coridum Knowledge Base. Follow the Finding number for the exact wording and the citation. Checked says who verified the row: machine means every automatic check passed and the surrounding text was read; person means someone read the sentence in the document. Rows are re-checked by a person over time. The studies are curated in the Coridum Knowledge Base; the reading of them together is a Claim, shown separately.
How strong is the evidence
-
In children attending daycare, a single French study suggests that higher indoor concentrations of two solvents — methyl isobutyl ketone and 1-methoxy-2-propyl acetate — go together with recurrent wheeze; for two further compounds the association did not survive correction for multiple testing.
A Claim is Coridum reading the Findings together, not a quotation from one study — according to Coridum. The grade follows the study designs behind it: A is the strongest, D means a single study or a mechanism.
