ABSTRACT:

TECHNICAL FIELD
The present invention relates to specific fabric softener actives that are suitable for preparation of concentrated fabric softening compositions. Specifically, acylated derivatives of triethanolamine are provided that solve problems that have previously gone unnoticed, particularly for clear, or translucent liquid compositions.
BACKGROUND OF THE INVENTION
Concentrated clear compositions containing ester and/or amide linked fabric softening actives are disclosed in co-pending application Ser. No. 08/679,694, filed Jul. 11, 1996 in the names of E. H. Wahl, T. Trinh, E. P. Gosselink, J. C. Letton, and M. R. Sivik, for Fabric Softening Compound/Composition, said application being incorporated herein by reference. The fabric softener actives in said applications are all biodegradable ester-linked materials, containing, long hydrophobic groups unsaturated chains. Concentrated compositions in the form of dispersions are also contemplated.
SUMMARY OF THE INVENTION
The essential fabric softening compounds herein are those having the formula:
[RC(O)OC

]
n
N
+
(R

)
m
X
−
wherein each R in a compound is a C
6
-C
22
, preferably with only minimal, or no, C
6-10
, hydrocarbyl group, preferably having an Iodine Value (hereinafter also referred to as IV) of from about 70 to about 140 based upon the IV of the equivalent fatty acid, n is a number from 1 to three on the weight average in any mixture of compounds, each R
1
in a compound is a C
1-3
alkyl or hydroxy alkyl group, the total of n and the number of R
1
groups that are hydroxyethyl groups equaling 3, n+m equaling 4, and X is a softener compatible anion, preferably methyl sulfate. Preferably the cis:trans isomer ratio of the fatty acid (of the C18:1 component) is at least about 1:1, preferably about 2:1, more preferably 3:1, and even more preferably about 4:1, or higher.
The compound, or mixtures of compounds, have (a) either a Hunter “L” transmission of at least about 85, typically from about 85 to about 95, preferably from about 90 to about 95, more preferably above about 95, if possible; (b) only very low, e.g., non-detectable levels, at the conditions of use, of odorous compounds selected from the group consisting of: isopropyl acetate; 2,2′-ethylidenebis(oxy)bispropane; 1,3,5-trioxane; and/or short chain fatty acid (4-12, especially 6-10, carbon atoms) esters, especially methyl esters; or (c) preferably, both.
The above compounds are suitable for use in concentrated fabric conditioning compositions, especially in clear, concentrated compositions. The compounds provide improved compositions containing:
A. from about 2% to about 75%, preferably from about 8% to about 70%, more preferably from about 13% to about 65%, and even more preferably, from about 18% to about 40%, of said compound, or mixtures of such compounds; and
B. less than about 40% by weight of the composition of principal solvent having a ClogP of from about 0.15 to about 0.64, and at least some degree of asymmetry.
Also, the compositions can be aqueous, stable fabric softener dispersion compositions containing: from about 5% to about 35%, preferably from about 8% to about 30%, more preferably from about 10% to about 28%, and even more preferably from about 13% to about 26%, by weight of the composition, of said cationic fabric softener compound.
For the clear compositions, the solvent is typically less than about 40%, preferably from about 5% to about 35%, more preferably from about 10% to about 25%, and even more preferably from about 12% to about 18%, by weight of the composition, especially of principal solvent having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60. Said solvent is typically the principal solvent. When there is an insufficient amount of principal solvent e.g.: 2,2,4-trimethyl-1,3-pentanediol; the ethoxylate, diethoxylate, or triethoxylate derivatives of 2,2,4-trimethyl-1,3-pentanediol; 2-ethyl-1,3-hexanediol; and/or 2-ethyl-1,3-hexanediol ethoxylates (1-3) and/or mixtures thereof, to provide a clear product, or even to provide a stable product, other solvents can be added, preferably 1,4-cyclohexanedimethanol.
The typical principal solvent is preferably selected from the group consisting of:
I. mono-ols including:
a. n-propanol; and/or
b. 2-butanol and/or 2-methyl-2-propanol;
II. hexane diol isomers including: 2,3-butanediol, 2,3-dimethyl-; 1,2-butanediol, 2,3-dimethyl-; 1,2-butanediol, 3,3-dimethyl-; 2,3-pentanediol, 2-methyl-; 2,3-pentanediol, 3-methyl-; 2,3-pentanediol, 4-methyl-; 2,3-hexanediol; 3,4-hexanediol; 1,2-butanediol, 2-ethyl-; 1,2-pentanediol, 2-methyl-; 1,2-pentanediol, 3-methyl-; 1,2-pentanediol, 4-methyl-; and/or 1,2-hexanediol;
