Abstract
Cleaning and/or benefit compositions comprising a formaldehyde-generating agent, particularly a formaldehyde-containing crosslinking agent, and a formaldehyde scavenger are disclosed. Processes for making and using the aforementioned compositions are further disclosed.
Claims24
A composition comprising:
- a. a formaldehyde-containing crosslinking agent selected from the group consisting of methylol and alkoxymethyl derivatives of urea, methylol and alkoxymethyl derivatives of ethylene urea, methylol and alkoxymethyl derivatives of propylene urea, and mixtures thereof;
- b. a formaldehyde scavenger selected from the group consisting of ethylene urea, urea, and 4,5-dihydroxyl ethylene urea;
- and
- c. an optional adjunct ingredient.
1 more element
A composition comprising:
- a. from about 0.1% to about 30%, by weight of a polyurethane material selected from the group consisting of a polyurethane, a polyurethane copolymer and mixtures thereof, said polyurethane and polyurethane having a Tg of from about −50° C. to about 150° C.;
- b. a cross-linking agent, said crosslinking agent being present in a ratio of polyurethane to crosslinking agent of from about 100:1 to about 1:2;
- c. a catalyst, said catalyst being present in a ratio of crosslinking agent to catalyst of from about 100:1 to about 1:5;
- d. a formaldehyde scavenger selected from the group consisting of ethylene urea, urea, and 4,5-dihydroxyl ethylene urea;
- e. an optional adjunct ingredient.
2 more elements
A method of reducing formaldehyde in compositions containing a formaldehyde-containing crosslinking agent, comprising the steps of
- a. providing a composition comprising formaldehyde or a formaldehyde-containing crosslinking agent;
- and
- b. providing a formaldehyde scavenger selected from the group consisting of ethylene urea, DHEU, urea, and mixtures thereof in an amount effective to reduce formaldehyde concentration in the composition.
