Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain sterically hindered amine salt compounds. Dyed products and articles are effectively stabilized against color degradation. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.

Stabilized body care products, household products, textiles and fabrics

Sterically hindered hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of formulae (5)-(7) These compounds are particularly effective in stabilizing aqueous polymer systems against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are effective for example in stabilizing water borne coatings, aqueous inks, aqueous ink jet media and photocured aqueous systems.

Water compatible sterically hindered alkoxyamines and hydroxy substituted alkoxyamines

Sterically hindered hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of the formula (8)-(10) These compounds are particularly effective in stabilizing aqueous polymer systems against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are effective for example in stabilizing water borne coatings, aqueous inks, aqueous ink jet media and photocured aqueous systems.

Sterically hindered alkoxyamine and hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of the formula where for example E and E' are 2-hydroxycyclohexyloxy, 2-hydroxy-2-methylpropoxy, benzyloxy, methoxy, propoxy, hexyloxy, heptyloxy, octyloxy or cyclohexyloxy, Ris for example &#x2014;NHCHCHOH Cl, &#x2014;NHOAc, &#x2550;NOH, &#x2014;NHCH(CH)COOK, &#x2014;NHCHCHN(CH)OAc, &#x2014;NHCHCHSOK, &#x2014;NHCH(COOK)CHCHSCH, &#x2014;NHCHCOOK, &#x2014;OCH(CH)COOK, &#x2014;OCHCHN(CH)OAc, &#x2014;OCHCHSOK, &#x2014;OCH(COOK)CHCHSCHor &#x2014;OCHCOOK, and where Rcomprises repeating units of &#x2014;(OCHCH)&#x2014;, &#x2014;(OCHCH(CH))&#x2014;, &#x2014;(CHCHCOOH)&#x2014;, &#x2014;(CHC(CH)COOH)&#x2014;, &#x2014;(CHCHCOOCH)&#x2014;, &#x2014;(NHCHCH)&#x2014;, &#x2014;(CHCHOH)&#x2014;, &#x2014;(CHCHCONH)&#x2014; or &#x2014;(CHCH(NHCOH))&#x2014;. These compounds are particularly effective in stabilizing aqueous polymer systems against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are effective for example in stabilizing water borne coatings, aqueous inks, aqueous ink jet media and photocured aqueous systems.
