Definitions

  • the present invention is concerned with an ingredient preventing viscosity problems encountered in a perfumed concentrated fabric softener in liquid form.
  • the invention is further related to a process for prevention of viscosity problems in a perfumed concentrated fabric softener, a softener produced according to the process and the use of the ingredient.
  • Fabric softeners in liquid form to be added in the rinse step of a laundry cycle are well known. It is, since long, common practice that the fabric softeners are perfumed by fragrances incorporated in the softener composition.
  • softener compositions comprise at least a dispersion of cationic surfactants in water, see, e.g. happi, March 1995, 95 - 97.
  • other usual components can be present, e.g. non ionic surfactants, anti-foaming agents, fluorescents, colourants, optical brightening agents and the like.
  • a common composition of a concentrated fabric softener which is about 3 or 4 times higher in concentration than a normal fabric softener, contains about
  • the cationic surfactant can be dihardened tallow dimethyl ammonium chloride (available from Akzo as Arquad ® 2HT), the ionic surfactant can be a tallow alcohol with 15 mole ethylene oxide (available as Genapol T ® from Hoechst) and the fragrance can be any of the fragrances usually used in this connection, e.g. any mixture of odorant materials of natural and/or synthetic origin suitable for perfuming fabric softeners, e.g. a floral fragance (Perfume A) or a lavender fragrance (Perfume B) or a mixture of fragrances.
  • a floral fragance Perfume A
  • Perfume B lavender fragrance
  • the object of the invention is to find an ingredient to be added to the fragrance used for perfuming a concentrated fabric softener or directly to the perfumed concentrated fabric softener in liquid form in order to avoid or at least to reduce the instability and to stabilize the viscosity, respectively, to such an extent that the softener can be handled without restrictions, i.e. the concentrated fabric softener in liquid form should be stable with respect to viscosity within a shelf life time of about two months at 37 o C after the production date. It was found that the two months stability at 37 o C is equivalent to about four months at room temperature (20-25 o C).
  • the active component(s) either should not be cleaved by the lipase or if the lipase is able to cleave the active component(s) the resultant reaction products should not negatively influence the smell of the perfume added to the concentrated fabric softener, i.e. the reaction products should not have a deleterious odoriferous effect after enzymatic cleavage.
  • R is a radical of a monohydric aliphatic alcohol or a group (CH 2 ) n COOR 1 or a group CH 2 -CH(OCOR 4 )-CH 2 (OCOR 5 ) and Y is R' which is a saturated or unsaturated straight or branched C 6 -C 24 alkyl group, preferably a C 7 -C 24 alkyl group, a group (CH 2 ) n COOR 1 or a group CH 2 -C(OH) (COOR 2 )-CH 2 (COOR 3 ), wherein n is 1 to 6, and R1 - R5 are each a radical of a monohydric aliphatic alcohol, the afore mentioned instability and viscosity problem, respectively, is prevented.
  • R' is saturated or unsaturated straight or branched C 12 - C 16 alkyl.
  • ester I is a diester (Ia) or a triester (Ib, Ic) of one of the general formulae: , wherein R, R2, R3 and R', R4, R5, respectively, are identical.
  • ester I is at least one of the group consisting of propylene glycol dicaprylate/dicaprate, trioctyl citrate, dioctyl adipate, triheptanoin and octyl octanoate.
  • the concentrated fabric softener comprises the ester I in an amount of about 0,05 to 5%, preferably of about 0,15 to 0,5%.
  • ester I is at least one of the group consisting of propylene glycol dicaprylate/dicaprate, triheptanoin and trioctyl citrate, because after enzymatic cleavage the reaction products of propylene glycol dicaprylate/dicaprate and triheptanoin are non-odoriferous and trioctyl citrate is not cleaved at all.
  • Propylene glycol dicaprylate/dicaprate is a mixture of the propylene glycol diesters of caprylic and capric acids.
  • the ingredient is added in an amount of up to 30%, most preferably of about 16%, of the fragrance used to perfume the concentrated fabric softener.
  • Rewoquat WE 18 supplied by Rewo company, is di-(tallow carboxyethyl)hydroxy ethyl methylammonium methosulfate.
  • test temperature of 37 o C is preferred because it reduces the testing time. In all further described experiments therefore the test temperature is 37 o C.
  • composition II a fabric softener with the same composition except that the fragrance was substituted by the same amount of water
  • composition III a fabric softener with the same composition except that the fragrance was substituted by the same amount of water
  • fragrance storage time at 37 o C production date after 1 week after 2 weeks Perfume A 15 mPa 200 mPa >500 mPa Perfume B 15 mPa 152 mPa solid
  • the solution of the problem can be solved simply by adding an ingredient comprising at least one compound of formula I to the perfume used to perfume the concentrated fabric softener or to the already perfumed concentrated fabric softener.
  • the performance is divided roughly in three categories with respect to the viscosity values after 2 months, viz. very efficient ⁇ 20 mPa, efficient 21 ⁇ 40 mPa, still reasonable efficient 41 ⁇ 150 mPa.
  • R is a radical of a monohydric aliphatic alcohol or a group (CH 2 ) n COOR 1 or a group CH 2 -CH(OCOR 4 )-CH 2 (OCOR 5 ) and Y is R' which is a saturated or unsaturated straight or branched C 6 -C 24 alkyl group, preferably a C 7 -C 24 alkyl group, a group (CH 2 ) n COOR 1 or a group CH 2 -C(OH) (COOR 2 )-CH 2 (COOR 3 ) , wherein n is 1 to 6, and R1 - R5 are each a radical of a monohydric aliphatic alcohol, overcomes the afore mentioned problem.
  • Prefered R' is a C 12 - C 16 alkyl.
  • the ingredient is also effective if it contains more than one ester, especially more than one of those mentioned in column 1 and /or 2 of Table III.
  • the lipase works during the drying cycle, i.e. after the wet fabric from the washing cycle, in which a lipase containing powder detergent is used, has been handled in the following rinse step with the fabric softener. So, in case of the use of a fabric softener containing the ingredient as described before the lipase contained in the water remaining in the fabric, even if the fabric has been centrifuged between the washing cycle and rinse step, may attack the esters in the fabric softener, especially the ester of the fragrance.
  • the ester(s) of the general formula I with the restrictions as specified above comprised in the ingredient preventing the viscosity problem encountered in a perfumed concentrated fabric softener might as well be attacked by the lipase to yield an alcohol. As said before this alcohol should not negatively influence the smell of the fabric softener.
  • the esters can be cut by the lipase by the following reaction to yield an alcohol according to the general reaction:
  • the other three tested esters are not cleaved or are enzymatically cleaved but are producing non odoriferous alcohols according to the following reactions:
  • R in the general formula I is a radical of a non-odoriferous alcohol of formula ROH.
  • a process for prevention of viscosity problems in a perfumed concentrated fabric softener is performed in that the ingredient as described before is added to said softener.
  • the addition of the ingredient may be done during the production of the softener or after the softener has already been produced.
  • Addition of the ingredient to the fragrance which is used to perfume the concentrated fabric softener is the prefered method.
  • As the afore described experiments signify it is advisable to incorporate the ingredient into the complete softener soon after the production date or, what is more recommended, immediately after the production.
