Embodiment

[0070] The invention is illustrated by the following non-limiting examples. Other embodiments suitable within the scope of the present invention will also be apparent to those of ordinary skill in the art. A. Preparation of CPE and RSE Compound 1

[0071] Glucopentaester was prepared in which 50% (approximately) of the ester groups were acetyl and 50% (approximately) decanoyl.

[0072] α-D Glucose (0-111M) was added to pyridine at room temperature. Acetyl chloride (0.254M) and decanoyl chloride (0.278M) were mixed, and the acid chloride mixture was added dropwise to the glucose solution, and the acid chloride was added slowly over about 1.5 hours. During the course of the reaction, a large amount of white turbid precipitate was formed, and ethyl acetate was added to maintain the fluidity of the reaction mixture.

[0073] The reaction mixture was stirred overnight (>16 hours) at room temperature. The reaction mixture was filtered to remove solid pyridine hydrochloride and e...

Embodiment 48 and 49

[0115] Examples 48 and 49 Prepare aqueous emulsions / dispersions containing 5% active ingredient containing a mixture of fabric softener and sucrose ester in a ratio of 1:4. 0.3% fragrance was added to the composition and the persistence of the fragrance was determined. See Table 11 below.

Abstract

A fabric softening composition that softens fabrics without affecting the absorbency of the fabric is provided. The conditioner comprises: i) a liquid or soft solid derivative of a cyclic polyol (CPE) or of a reduced saccharide (RSE) resulting from 35 to 100 % of the hydroxyl groups in the cyclic polyol or reduced saccharide being esterified or etherified, the derivate (CPE or RSE) having at least 2 or more of ester or ether groups independently attached to a C8-C22 alkyl or alkenyl chain or mixtures thereof, and containing at least 35 % tri or higher esters; ii) a deposition aid. Also liquid or soft solid fatty acid esters of glucose comprising a mixture of C2-C22 alkyl or alkenyl chains and resulting from a cyclic polyol as above are provided.

Description

[0001] Field [0002] The present invention relates to fabric softening compositions. In particular, the present invention relates to compositions which soften fabrics without affecting the absorbency of the fabrics. Background technique [0003] Rinse added fabric softening compositions are known. However, conventional rinse conditioners have the disadvantage that although they increase the soft feel of fabrics, they simultaneously reduce the hygroscopicity of fabrics. Decreasing the hygroscopicity of a fabric means its ability to absorb moisture is reduced. This is especially detrimental to towels, as users demand softness but also high moisture absorption. [0004] Co-pending application GB 9518012.1 (Unilever) discloses a liquid fabric conditioning composition comprising a substantially water-insoluble fabric softening compound. The phase structure of the composition was shown by X-ray crystallography to be larger tha...
