Definitions
- This invention relates to a laundry detergent composition which is suitable for laundering fine fabric materials such as wool, silk, nylon, polyester and the like under relatively mild washing conditions.
- Laundry detergent compositions generally employ anionic surfactants as the primary detergent-active compounds, such as alkyl benzene sulphonates, fatty alcohol sulphates or alkyl glycol ether sulphates.
- anionic surfactants damage the fibre structure of sensitive fabrics upon repeated washing. Fine fabric wash foririulations tend to contain a blend of anionic surfactants with non-ionic or amphoteric surfactants.
- the non-ionic surfactants are intended to increase detergency.
- sensitive woollen fabrics are washed with non-ionics, the fabrics tend to feel comparatively hard and brittle. These effects can be intensified with machine washing.
- amphoteric surfactants do not completely counteract the loss of feel and, although amphoteric surfactants act as fibre-softening agents, some anionic and non-ionic surfactants reduce the softening effect of the amphoteric surfactants. Also, most known softening agents which are incorporated into detergents are detrimental to cleaning performance . There is therefore a need for a fine fibre wash formulation which can be used to ash delicate fabrics such as woven or knitted wool_en fabrics and silk, which gives a good cleaning performance without having a detrimental effect o ⁇ the properties of the fabric, and whicn e n sures that the treated fabric has a soft feel .
- a laundry detergent composition for washing delicate fabrics comprising:
- anionic, non-iome or amphoteric surfactants or a mixture of two or more thereof b) a natural and/or synthetic ceramide; c a silicone; and optionally other detergent _ngred ⁇ ents
- the detergent compos_t ⁇ cn comprises :
- the silicone is a silicone f_ ⁇ ⁇ d, more preferably a silicone emulsion, and most preferably a silicone micro-emulsion Examp_.es of suitable silicones are polyalkyl or polyary_ silicones. Particularly preferred silicones are polydimethylsiloxanes , with organic groups incorporated into the basic silicone backbone, having the following structure:
- R is an amino, polyether, epoxy, hydroxyl, polyether/ammo, polyether/epoxy or cyclohexyl functional group
- A may be any ⁇ roup suitable for ending the silicone chains, for example a hydrogen, methyl or hydroxyl grouo
- a and b are integers, preferably between 7 and 5000.
- Suitable silicones are those marketed under the trade names DC 225 (pro ⁇ uced by Dow Corning Corporation) and Magnasoft EM 410 oroduced by itco) .
- the concentration of silicone in the compositions of the invention suitably lies in tne range from 0.05 to 5 wt %, preferably 0.1 to
- silicone concentration is about 0.5 wt %.
- the ceramide present m the composition of the present invention may be a natural ceramide or a synthetic ceramide, for example an -acylsphmgenme or a derivative thereof.
- the amide-linked fatty acids are generally characterised by a C 16 to C 26 , C Conduct 0 /w-OH or C 32 /w-OH cnain.
- the long chain amine may be sphmgosme or sphmganme or phytosphingosine .
- ceramides are Bis (N-hydroxyethyl cetyl) Malanomide which is marketed under the trade name Questamide H and produced by Quest (this is synthetic "ceramide 2", with ceramide 2 being naturally found m hair) ; Palmitado-se ⁇ nate de myristyl which is marketed under the trade name ceramide A2 and produced by Sederma; Palmitadohexadecanediol which is marketed under the trade name Ceramide ⁇ and produced by Quest and a glycosphmgolipid marketed under the trade name ceramide PG5 and produced by Seporga.
- composition of the present invention may contain only one ceramide, or, alternatively, two or more different ceramides may be present.
- concentration of cerami ⁇ e m the compositions of the invention suitably lies in the range from 0.001 to 5 wt %, preferably 0.001 to 2 wt % and most preferably 0.01 to 1 wt %.
- the composition of the present invention further includes detergent-active compounds. Many suitable detergent-active compounds are available and are fully described in the literature.
- the total amount of surfactant present in the composition of the present invention ranges from 2 to 60 ,vt _ by weight of the total fine fabric detergent composition, preferably 5 to 40 wt %, and most preferably 10 to 20 wt %.
- anionic surfactant is not limited and any anionic surfactant suitable for use m a laundry composition may be used.
- suitable anionic surfactants are alky_benzene sulphonates, particularly linear alkylbenzene sulphonates having an alkyl chain length of C 8 -
- anionic surfactants are sodium lauryl ether sulphate, which is available under the trade name EMPICOL ESC3 from Albright &
- the anionic surfactants are desirably present in amounts of 2 to 30 wt %, preferably 5 to 20 wt %, and most suitably the anionic surfactant concentration is about 10 wt %.
- non-ionic surfactant is also not limited and any non-ionic surfactant suitable for use in a laundry composition may be used.
- non-ionic surfactants are primary and secondary alcohol ethoxylates, especially the C 8 - C 20 aliphatic alcohols ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol, and most particularly the C 10 - C 15 primary and secondary aliphatic alcohols ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol.
- Non-ethoxylated non-ionic surfactants include alkyl polyglycosides, glycerol monoethers, alkanol amides and olyhdroxyamides (glucamide) .
