FR2759607A1 - PROCESS FOR THE PREPARATION OF PEARL SHINE CONCENTRATES, SURFACTANTS - Google Patents

Abstract

A process for the production of pearlescent luster concentrates is proposed by mixing aqueous anionic surfactants with pearl luster waxes, in which concentrates of aqueous anionic surfactants are used which are present in the lamellar gel phase. By mixing the components in the gel phase, concentrates are obtained which are characterized by a brilliant pearly luster.

Description

Field of the Invention The invention relates to a process for the preparation of

  pearlescent luster concentrates in which pearlescent luster waxes are dispersed in gels of aqueous anionic surfactants. State of the art

  The shine which presents the soft pearly aspect of the

  has exercised them on men already for millennia a

  special fascination. There is therefore no surprise.

  This is because manufacturers of cosmetic preparations try to give their products an attractive, precious, good-looking image. The first pearly aspect implemented since the Middle Ages in cosmetics, was

  a pearly sheen paste based on natural fish scales-

  the. At the beginning of this century, it was discovered that bismuth oxychlorides are also able to produce a pearly luster. For modern cosmetics, on the contrary, waxes with a pearly appearance, in particular of the type of glycolmono and di-fatty acid esters are important, these are mainly used to obtain the shine

  pearly in hair shampoos and gels for dou-

  ches. A review of modern pearlescent formulations is described by A. Ansmann and R. Kawa in Parf. Kosm. 75

(1994) 578.

  The state of the art knows a large number of formulations which give the surfactants the desired pearly luster. This is how, for example,

  two German patent applications DE-A1-3 843 572 and DE-A1-

  4,103,551 (Henkel) pearlescent concentrates in the form of flowable aqueous dispersions which contain 15 to 40% by weight of pearlescent components, 5 to% by weight of emulsifying agents and 0, 1 to 5 or 15 to% by weight of polyols. For pearlescent waxes, these are acylated polyalkylene glycols, monoalkanolamides, linear, saturated fatty acids or ketosulfones. In the two European documents EP-B1-0 181 773 and EP-B1-0 285 389

  (Procter and Gamble) we proposed sham compositions

  punches which contain surfactants, silicones

  non-volatile and pearlescent waxes. The object of the de-

  European patent application EP-A2-0 205 922 (Henkel) consists of

  concentrates with a pearly luster capable of flow which contain

  ment from 5 to 15% by weight of acylated polyglycols, from 1 to 6% by weight of fatty acid monoethanolamides and from 1 to 5% by weight of nonionic emulsifying agents. In accordance with the teaching of European patent EP-B1-0 569 843 (Hoechst), it is also possible to obtain pearly luster dispersions capable of flow, nonionic, in which mixtures of 5 to 30% by weight of acylated polyglycols and 0.1

  at 20% by weight of selected nonionic surfactants-

  born. Also known from the European patent application EP-

  A2-0 581 193 (Hoechst) pearlescent dispersions free of preservative, flowable, which contain acylated polyglycol ethers, betaines, agents

  anionic surfactants and glycerol. Finally, we have pro-

  posed in European patent application EP-A1-0 684 302 (Th.

  Goldschmidt) the use of polyglycerol esters as ad-

  crystallization aid for the preparation of concentrates

pearly luster.

  Aqueous anionic surfactants form

  as is known for higher concentrations of ma-

  solid, high viscosity gels, which are designated as lamellar phases. When handling with

  aqueous preparations of anionic surfactant, the tech-

  nicien therefore generally operates in the area

  lower concentrations. For the preparation of con-

  centered with pearlescent radiance surfactants we start with different solutions

  reads of anionic surfactants in which the pearlescent waxes are dispersed at high temperatures. After homogenization the preparations can be adjusted

  then, if desired, at a defined concentration of solid material. The concentrates accessible according to this process do not however have any pearly luster on their side, however they appear much rather cloudy, which is not desirable from an aesthetic point of view.

  The problem of the present invention therefore consisted in making accessible a process by which it is possible to obtain concentrates with pearlescent radiance surfactants,

  which themselves have an exceptional pearly luster.

Description of the invention

  The object of the invention is a process for obtaining concentrates with pearlescent radiance surfactants by mixing aqueous anionic surfactants with waxes with pearlescent radiance which is characterized in that concentrates of surfactants are used aqueous anionics which arise in

lamellar gel phase.

  Surprisingly, we found that we can

  obtain pearlescent concentrates with a pearlescent radiance

  specific, when we implement di-

  of anionic surfactants, solutions

  aqueous concentrates of anionic surfactants,

  especially concentrated solutions of alkyl ether sulfate and monoglyceride sulfate which are in the form of a lamellar gel phase. The incorporation of pearlescent waxes into viscous anionic surfactants is successfully carried out at increased temperatures ranging from 50 to 90 ° C.

  without problems with strong stirring and we obtain preparations

  concentrated concentrations which also manifest after cooling

the desired pearly luster.

  Anionic surfactants Typical examples of anionic surfactants that come into consideration as raw materials in the

  process according to the invention are the alkylbenzenesulfona-

  tes, alkanesulfonates, olefinsulfonates, alkyl-

  thersulfonates, glycerolethersulfonates, a-methyl-

  estersulfonates, sulfonated fatty acids, alkylsulfates, ethersulfates of fatty alcohols glycerolethersulfates,

  hydroxyethermixthersulfates, monoglycerides (ether) -

  sulfates, amides (ether) fatty acid sulfates, mono-

  and dialkylsulfosuccinates, mono- and dialkylsulfosuc-

  cinamates, sulfotriglycerides, amide soap, ether carboxylic acids, and their salts, fatty acid isethionates, fatty acid sarcosinates, fatty acid taurides, Nacylamino acids such as, for example, acyllactylates, acyltartrates, acylglutamates, and

  acylaspartates, alkyloligoglucosidesulfates, conden-

  protein and fatty acid (especially products

  wheat-based) and alkyl (ether) phosphates.

  As far as anionic surfactants are concerned,

  ment of polyglycol ether chains, these can have a conventional counterpart distribution, preferably nevertheless a restricted distribution. It is critical for the use of the surfactants mentioned that they occur in the lamellar gel phase. This means in practice that usually aqueous solutions are used which exhibit a solid content in the region of

  to 90, preferably from 70 to 80% by weight.

  Alkylethersulfates In a preferred embodiment of the invention, anionic surfactants of the type of alkylethersulfates are used, which are prepared on the scale of

  large industry by sulfation by SO3 or by chloro-acid

  rosulfonic (CSA) of polyglycol ethers of oxoalcohol or fatty alcohol and subsequent neutralization. In the sense of the invention, consideration is given to ethersulphates which correspond to formula (I), R O- (CH2CH20) mSO3X (I) in which R represents an alkyl and / or alkenyl radical

  linear or branched having 6 to 22 carbon atoms, m re-

  has numbers from 1 to 10, and X represents a met

  alkali and / or alkaline earth tal, ammonium,

  alkylammonium, alkanolammonium or glucammonium. Examples

  typical are the sulfates of the adducts of, on average, 1 to 10 and in particular 2 to 5 mol of oxide

  ethylene on caproic alcohol, caprylic alcohol, 2-

  ethylhexylalcohol, caprinic alcohol, lauric alcohol,

  isotridecyl alcohol, myristic alcohol, cetyl alcohol

  lique, palmoleic alcohol, stearic alcohol, isostearic alcohol, oleyl alcohol, elaidic alcohol,

  petroselinic alcohol, arachic alcohol, gado- alcohol

  leic, behenic alcohol, erucic alcohol, and brassidic alcohol as well as their industrial mixtures in the form of their sodium and / or magnesium salts. Ethersulfates Fatty acid and alkylene glycol esters Fatty acid and alkylene glycol esters (a)

  represent the best known pearlescent waxes.

  They are preferably mono- or diesters of ethylene

  neglycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, dipropylene glycol as well as their mixtures with fatty acids having from 6 to 22, preferably from 12 to 18 carbon atoms. Typical examples are ethylene glycol monostearate, distearate

  ethylene glycol and mixtures thereof.

  Fatty acid alkanolamides The fatty acid alkanolamides which form component b) represent fatty acid amides having from 6 to 22, preferably from 12 to 18 carbon atoms, with

  alkanolamides such as monoethanolamine, di-

  ethanolamine, monopropanolamine, dipropanolamine, and the like. Typical examples are monoethanolamide

  of stearic acid or the diethanolamide of coconut fatty acids.

Partial glycerides

  By partial glycerides (c) is meant mono- and diglycerides and their industrial mixtures.

  trials which represent -considered from a chemical point of view-7 partial esters of fatty acid having from 6 to 22, preferably from 12 to 18 carbon atoms, with glycerol. 25 Typical examples are the monoglyceride lauric acid, coconut fatty acid monoglyceride, palmitic acid monoglyceride, stearic acid monoglyceride, isostearic acid monoglyceride, acid monoglyceride

  oleic or behenic acid monoglyceride.

  Multivalent esters of carboxylic acid and hydroxycarboxylic acid

  For pearly luster waxes that form the com-

  posing (d), these are known substances which can be obtained according to the common processes of organic chemistry

preparatory.

  Usually the preparation of esters

  is carried out in a manner known per se by esterification

  talysed with bases of carboxylic acids and / or hydroxycarboxylic acids having from 4 to 12 carbon atoms, 2 to 4

  carboxyl groups and 1 to 5 hydroxyl groups, with the al-

  fatty cools. As acid components, for example, malonic acid, maleic acid, fumaric acid, adipic acid, sebacic acid, azelaic acid, dodecanic acid, phthalic acid, isophthalic acid, and in particular succinic acid as well as malic acid, citric acid, and in particular tartaric acid and their mixtures. Fatty alcohols contain from 6 to 22, preferably from 12 to 18 and in particular from 16 to 18

  carbon atoms in the alkyl chain. Typical examples

  what are capronic alcohol, caprylic alcohol, 2ethylhexyl alcohol, caprinic alcohol, lauric alcohol,

  isotridecylic alcohol, myristic alcohol, cetyl alcohol

  lique, palmoleic alcohol, stearic alcohol, isostearic alcohol, oleyl alcohol, elaidic alcohol,

  petroselin alcohol, linoleic alcohol, linol alcohol

  lenic, elaeostearic alcohol, peanut alcohol, gadoleic alcohol, behenic alcohol, erucic alcohol and

  brassidic alcohol and their industrial mixtures.

  Esters can be presented as complete esters or

  partial esters, preferably mono-

  and especially diesters, carboxylic acids or hydroxy-

  carboxylic. Typical examples are the mono- and dies-

  lauric succinic acid, mono- and

  dicetearylesters of succinic acid, mono- and disteary-

  succinic acid lesters, tartaric acid mono- and dilaurylesters, tartaric acid mono- and dicocosalkylesters, tartaric acid mono- and dicetearylesters, citric acid mono-, di- and trilaurylesters, mono-,

  citric acid di- and tricocosalkylesters as well as the mo-

  no-di- and tricetearylesters of citric acid.

Long chain solids

  Among the long chain solids we must

  take fatty alcohols, fatty ketones, fatty ethers and fatty carbonates which generally have 24 to

  48, preferably from 32 to 36 carbon atoms. For the al-

  long-chain fatty cools these are generally dodecosene with lauric alcohol, coconut fatty alcohol,

  myristic alcohol, cetyl alcohol, cetearyl alcohol

  as, stearic alcohol, isostearic alcohol, oleyl alcohol, elaidic alcohol, petroselinic alcohol, linolic alcohol, linolenic alcohol, behenic alcohol, and / or erucic alcohol. Preferably, ring opening products of hexa- and / or octadecene epoxides are used with fatty alcohols having from 16 to 18 carbon atoms. Other surfactants In the sense of the process according to the invention,

  can be used in conjunction with surfactants

  anionic agents, also other non-ionic surfactants

  ques, cationic, amphoteric and / or zwitterionic provided that their quantity is so small that it does not exert an unfavorable influence on the constitution of the lamellar gel phase. Typically, the proportion of additional surfactants in concentrates

  of anionic surfactants ranges from 1 to 15, preferably

  from 5 to 10% by weight, based on the total content of

  surfactants. Typical examples of surfactants

  nonionic tif are ethers of fatty alcohol and poly-

  glycol, alkylphenol ethers and polyglycol, fatty acid esters and polyglycol, acid amide ethers

  fatty and polyglygol, ethers of fatty amines and po-

  lyglycol, alkoxylated triglycerides, mixed ethers or

  mixed formals, alk (en) yloligoglucosides, N-

  fatty acid alkylglucamides, protein hydrolysates (in

  particularly vegetable products based on wheat),

  fatty acid and polyol ters, sugar esters,

  ters of sorbitan, polysorbates and amine oxides.

  Provided that the nonionic surfactants contain

  polyglycol ether chains, these can

  fester a distribution of conventional counterparts, preferably nevertheless a restricted distribution of counterparts. Typical examples of cationic surfactants are quaternary ammonium derivatives and quat esters, in particular the salts of fatty acid trialkanolamine esters

  can have a suitable distribution for this as well

  than a restricted distribution of counterparts. Particularly preferred is the use of aqueous ethersulphates based on adducts of, on average, 2 to 3 mol of ethylene oxide on industrial fractions of C12-C14 or C12 coconut fatty alcohols -C18, in the form of their sodium and / or magnesium salts, in which the concentration of solid matter for this again is in the region of 60 to 90,

  preferably from 70 to 80% by weight.

  11 Monoglyceride (ether) sulfates In another preferred embodiment of

  the invention, anionic surfactants are used

  that of the monoglyceridesulfate and monoglyceride type

  thersulfates. Usually, the starting point for their preparation is triglycerides which are transesterified if necessary after ethoxylation into monoglycerides and then sulfated and are neutralized. Simultaneously, it is possible to react the partial glycerides with suitable sulfating agents, preferably gaseous sulfuric anhydride or 2 (0 of chlorosulfonic acid [EP-B1-0 561 825, EP-B1-0 561 999 (Henkel)]. A special advantage when using

  these substances lies in the fact that monoglyceridesul-

  fates and monoethersulfates themselves have pearl luster properties. The monoglyceride (ether) sulfates to be used in the sense of the invention correspond to formula (II)

CH20 (CH2CH20) XCOR

  CH-O (CH2CH20) yH (II) 31I CH20 (CH2CH20) z-S03X in which R CO represents a linear or branched acyl radical having from 6 to 22 carbon atoms, x, y and z overall represent O or represent numbers ranging from 1 to 30, preferably from 2 to 10, and

  X represents an alkali or alkaline earth metal.

  Typical examples of monoglyceride (ether) -

  suitable sulfates in the sense of the invention are the pro-

  reaction tubes of lauric acid monoglyceride, mono-

  coconut fatty acid glyceride, palmitic acid monoglyceride, stearic acid monoglyceride, oleic acid monoglyceride, and tallow fatty acid monoglyceride, and their adducts ethylene oxide, with sulfuric anhydride or chlorosulfonic acid under

form of their sodium salts.

  Preferably, monoglycerides are used.

  desulphates of formula (II) in which R CO represents a linear acyl radical having from 8 to 18 carbon atoms. The concentration of solid matter in the aqueous pastes is again in the region of 60 to 90, and preferably 70

at 80% by weight.

Pearly shine waxes

  The choice of pearlescent waxes is not deter-

  undermining in the sense of the process according to the invention. Typical examples are:

  a) mono- and / or diesters of fatty acid and of alkyl-

  neglycol b) fatty acid alkanolamides c) partial glycerides d) multivalent esters of carboxylic acids and hydroxycarboxylic acids e) long chain substances and,

  f) products opening the epoxy cycle.

  Pearly luster waxes can be used

  works individually or in mixture. Usually their proportion

  In the concentrates, this amounts from 1 to 90, preferably from 50% by weight, relative to the concentrates, or from 25 to 100, preferably from 50 to 75% by weight, based on the content of

  anionic surfactants (calculated as solid). -

  Pearly luster waxes have an average part diameter

  cules ranging from 0.1 to 20, preferably from 5 to 15, and in par-

particular from 10 to 12 mm.

  oxidation products of the corresponding paraffins. These

  long chain fatty tones can be prepared according to

  the prior art processes, for example by pyro-

  lysis of the corresponding magnesium fatty acid salts. Ketones can have a symmetrical or unsymmetrical constitution

  metric and derive from fatty acids having from 6 to 22, preferably

  of 16 to 18 carbon atoms. For this, stearone is distinguished by advantageous properties, particularly properties of pearly luster. Long chain fatty ethers

  are usually prepared by acid condensation of al-

  corresponding fat cools. Fatty ethers with properties

  particularly advantageous tones of pearly luster, are obtained by condensation of fatty alcohols having from 16 to 22 atoms of

  carbon such as cetyl alcohol, cetane alcohol,

  ryl, stearic alcohol, isostearic alcohol, oleyl alcohol, behenic alcohol, and / or erucic alcohol. We

  particularly prefer here the use of disteary ether-

  lique. Long chain fatty carbonates are obtained by

  a process in which one transesterifies for example the

  dimethyl or diethyl bonate with fatty fatty alcohols

  respondents in a manner known per se. Consequently, the fatty carbonates can have a symmetrical or non-symmetrical structure. Particularly preferred are the transesterification products of dimethyl or diethyl carbonate, with cetyl alcohol, cetearyl alcohol, stearic alcohol, isostearic alcohol, oleyl alcohol, behenic alcohol and / or the erucic alcohol in the form of

  their mono- and diesters or their industrial mixtures.

  Opening products of the epoxy cycle For the opening products of the cycle, these are known substances which are usually prepared by

  acid catalyzed reaction of epoxy olefins termi-

  inside or inside, with aliphatic alcohols

  ques. Typical examples are the opening products of the epoxide a-dodecene, epoxide a-hexadecene, epoxy octadecene, epoxide a-eicosene, epoxide

  a-dodecosene, epoxy i-dodecene, epoxide i-

  hexadecene, epoxy i-eicosene and: or epoxide i-

  quaternized. Typical examples of surfactants am-

  photers or zwitterionics are alkylbetaines, alkyl-

  lamidobetaines, aminopropionates, aminoglycinates, imidazoliumbetaines and sulfobetaines. Preferably, the anionic surfactants are used, in particular

  especially alkyl ether sulfates and / or monoglyceridesulfa-

  tes, together with alkyloligoglucosides and / or betaines. Polyols

  In a particularly advantageous embodiment,

  geux of the invention, used jointly in the preparation

  ration of pearlescent concentrates for regulating viscosity, polyols which, in the sense of the invention, come into consideration preferably have from 2 to 15 carbon atoms and at least two hydroxyl groups. Typical examples are: - glycerol - alkylene glycols such as, for example, ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexylene glycol and also polyethylene glycols having an average molecular weight of 100 to 1000 Daltons, - industrial mixtures of oligoglycerols having a specific degree of condensation of 1.5 to 10, for example industrial mixtures of diglyderol, having a diglycerol content of 40 to 50% by weight,

  - methylolated compounds such as in particular trimethylo-

  lethane, trimethylolpropane, trimethylolbutane, pentaerythritol and dipentaerythritol, - (lower alkyl) glucosides, in particular those with 1 to 8 carbon atoms in the alkyl radical such as for example methyl and butylglucoside, - sugar alcohols having 5 to 12 carbon atoms, for example sorbitol or mannitol, - sugars having 5 to 12 carbon atoms such as, for example, glucose or sucrose,

  - amino sugars such as, for example, glucamine.

  The proportion of polyols in concentrates can

  increase from 0.1 to 30, preferably from 1 to 25 and in particular

bind from 5 to 15% by weight.

  Co-emulsifiers As other adjuvants and additive substances come into consideration co-emulsifiers which can either be used during dispersion or

  be mixed with concentrates later.

  As primary emulsifiers, surfactants

  anionic active agents as well as, where appropriate, surfactants

  assets mentioned in addition are thus naturally active, from a technical point of view of the use the following groups

  co-emulsifiers are, however, particularly advantageous.

  geux. 1- Adducts of 2 to 30 mol of ethylene oxide and / or

  from 0 to 5 mol of propylene oxide on fatty fatty alcohols

  born with 8 to 22 carbon atoms, on acids

  fatty having 12 to 22 carbon atoms and on alkyl-

  phenols having 8 to 15 carbon atoms in the radical

alkyl.

  2- Mono- and diesters of C12 / C18 fatty acid and adducts of 1 to 30 mol of ethylene oxide on

glycerol.

  3- Mono- and diesters of glycerol and mono- and diesters of saturated and unsaturated fatty acids having from 6 to 22 carbon atoms and their adducts with ethylene oxide. 4- Alkylmono- and oligoglycosides having 8 to 22 atoms

  carbon in the alkyl residue and their ethoxy analogs

the.

  - Adducts of 15 to 60 mol of ethylene oxide

  on castor oil and / or on hard castor oil-

co.

  6- Polyol esters and in particular poly- esters

  glycerol such as for example polygly polyricinoleate

  cerol or polyglycerol poly-12-hydroxystearate.

  Also suitable are mixtures of compounds from

  of several of these classes of substances.

  7- Addition products of 2 to 15 mol of ethylene oxide on

  castor oil and / or hardened castor oil.

  8- Partial esters based on linear C6-C22 fatty acid

  res, branched, unsaturated or saturated, of ricinoleic acid

  as well as 12-hydroxystearic acid and glycerol, polyglycerol, pentaerythritol, dipentaetythritol, sugar alcohols (for example sorbitol),

  alkylglucosides (e.g. methylglucoside, bu-

  tylglucoside, laurylglucoside) as well as polygluco-

side (for example cellulose).

  9- Trialkyl phosphates, as well as alkylphosphates

* of PEG mono-di- and / or tri.

- Wool wax alcohols.

  11- Polysiloxane-polyalkyl-polyether copolymers or the

corresponding derivatives.

  12- Mixed ethers based on pentaerythritol, fatty acids, citric acid and fatty alcohol according to document DE-PS 1 165 574 and / or mixed esters of fatty acids having from 6 to 22 atoms of carbon, methylglucose and polyols, preferably glycerol as well as,

13- polyalkylene glycols.

  The amount of Co-emulsifiers can increase by

  1 to 15, preferably 2 to 10% by weight relative to the con-

  centered. Silicone oils Another advantage of the concentrates which can be obtained according to the process according to the invention consists in

  the fact that they make it possible to emulsify equally

  silicone oils, without them being

  completely harm or have an adverse influence on

  the pearly luster. Typical examples of suitable silicone oils are dimethylpolysiloxane, methylphenylpoly-

  siloxane, cyclic silicones as well as amino compounds modified by an amino, a fatty acid, an alcohol, a polyether, an epoxy, a fluorine, and / or an alkyl which can be

  present at room temperature as well in li-

  only in the form of resin. The proportion of silicone oils in concentrates can range from 0.1 to 5, from

preferably 2 to 3% by weight.

  Preparation process For the preparation of pearlescent concentrates, we start with gels of surfactants (anionic) at 60-90% by weight, which are preferably heated from 50 to 90 C, so that the viscosity is lowered to the point where incorporation of pearlescent wax can take place without problem. Melted pearlescent wax is introduced

  by stirring in the heated and homogeneous surfactant gel

  neise intensively. If desired, additives can be added to this location as well as, for example, polyols, co-emulsifiers and silicone oils; then the concentrate is cooled. Concentrates

  obtained in this way have a content of so-

  lide of the order of magnitude of the surfactant gel used, even about 60 to 90% by weight. In particular therefore

  when using surface active agent gels

  particularly high centration, it is recommended to

  read the concentrates after preparation with water at a solid content of 30 to 60, preferably 40 to

% in weight.

Examples 1 to 4

  500 ml of 70% by weight sodium salt of C12 / C14 coconut fatty alcohols + 20E sodium sulphate or sodium cocomonoglycerides sulphate sodium salt were introduced into a 1 liter stirring apparatus. heated to 80 C. In the solutions, the melted pearlescent waxes and, where appropriate, the additives were dispersed and the mixture was stirred for the time necessary for the preparations to be homogeneous and cooled. Then the concentrates were diluted with an amount of water such that a solid content of 35% by weight was adjusted. The pearly luster of the preparations was

  rated on a scale from 3 = cloudy to 1 = bright.

  The composition of the concentrates according to the invention which results therefrom ranges from 1 to 4 and the results are collected in

table 1.

  Comparison examples V1 to V4 Examples 1 to 4 were repeated, however instead of the concentrated surfactant gels, aqueous solutions of the same composition but with a solid content of 40% by weight were used. The composition of the resulting comparison concentrates V1 to V4 and the

  results are also collated in table 1.
