Personal care products
Also: cosmetics, toiletries, body care products
Products applied to the body indoors — deodorants and antiperspirants, hairsprays, perfumes, creams and cosmetics — considered here as a source of the compounds they release into the air of the room in which they are used.
Why it matters indoors
Personal care products are used in the smallest and least ventilated room in most buildings, usually within a few minutes of waking, and often as an aerosol. Two features distinguish them from other indoor sources: the person applying them is directly in the plume, and the compounds involved include fragrance materials and siloxanes, which are otherwise uncommon indoors.
What has been measured
The same French daycare study that examined cleaning products grouped them together with personal care products and cosmetics in one statistical factor. That group was associated with ever wheeze treated with inhaled corticosteroids (odds ratio 1.22, 95 % CI 1.00–1.47) (F-0032).
Because the two categories fall in the same statistical factor, that study cannot separate them. Anyone claiming it shows which of the two matters is reading more into it than it contains.
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.
