Description

Field of the Invention

The invention relates to new liquid soap formulations, which are essential components selected sugar surfactants, fatty acid partial glycerides and fatty acids and other co-surfactants contain and their use in liquid soap preparations.

State of the art

The large number of liquid soaps that are offered to the consumer make it clear that there is a constant need among consumers for further improved products especially due to improved stabilities but also good dermatological tolerance, stronger lower foaming power, higher creaminess, rinsing power and skin feeling or regreasing award. In contrast, soap manufacturers are looking for soap-containing formulations that in addition to unchanged stability also have constant viscosities and also the allow easy incorporation of hydrolysis-sensitive substances.

The complex object of the present invention was therefore to use liquid soaps with the to provide the described complex requirement profile.

Description of the invention

The invention relates to liquid soaps containing

• a) 0.1 to 20% by weight of sugar surfactants selected from the group formed by (a1) alkyl and / or alkenyl oligoglycosides and / or (a2) fatty acid N-alkyl polyhydroxyalkyl amides,
• b) 0.1 to 20% by weight of fatty acid partial glycerides,
• c) 0.5 to 34% by weight of anionic, nonionic and / or amphoteric co-surfactants,
• d) 0.5 to 30 wt .-% fatty acids and

with the proviso that the quantities indicated with water and possibly other auxiliary and Add additives to 100% by weight.

Another object of the invention is the use of these agents in liquid soap making exercises.

Surprisingly, it was found that liquid soaps made from selected sugar surfactants, Partial glycerides, fatty acids and other co-surfactants can produce partial glycerides via a longer storage periods are stable. It is particularly surprising that the alkaline pH Value does not lead to an immediate hydrolysis of the partial glyceride, for example glycerol monooleate or the hydrolysis have no influence on the stability and viscosity of the liquid soap formulations Has. Another advantage is the stable and creamy foam and the regreasing or the Skin feeling.

Alkyl and / or alkenyl oligoglycosides

Alkyl and alkenyl oligoglycosides which make up the sugar surfactant component (a1) are known nonionic surfactants which follow the formula (I)

R ¹ O- [G] _p (I)

in which R ^{1 is} an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10. They can be obtained according to the relevant preparative organic chemistry processes. Representative of the extensive literature here is the review by Biermann et al. in Starch /force 45, 281 (1993), B. Salka in Cosm.Toil. 108, 89 (1993) and J. Kahre et al. in SÖFW-Journal Issue 8, 598 (1995).

The alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (I) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p must always be an integer in a given compound and especially here can assume the values p = 1 to 6, the value p for a certain alkyl oligoglycoside is an analytically determined arithmetic quantity, which usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, alkyl and / or alkenyl oligoglycosides are preferred whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4. The alkyl or alkenyl radical R ¹ can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capro alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as those obtained from Roelen's oxosynthesis in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes. Alkyl oligoglucosides of chain length C ₈ -C ₁₀ (DP = 1 to 3) are preferred, which are obtained as a preliminary step in the separation of technical C ₈ -C ₁₈ coconut fatty alcohol by distillation and with a proportion of less than 6% by weight of C ₁₂ -Alcohol can be contaminated and alkyl oligoglucosides based on technical C _9/11 oxo alcohols (DP = 1 to 3). The alkyl or alkenyl radical R ¹ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and the technical mixtures described above, which can be obtained as described above. Alkyl oligoglucosides based on hardened C _12/14 coconut alcohol with a DP of 1 to 3 are preferred.

Furthermore, the addition of unsaturated carboxylic acids, such as acrylic acid, is also possible. Regarding the nomenclature and in particular the distinction between betaines and "real" amphoteric surfactants, reference is made to the contribution by U. Ploog in Seifen-Öle-Fette-Wwachs, 198, 373 (1982). Further overviews on this topic can be found, for example, by A. O'Lennick et al. in HAPPI, Nov. 70 (1986), S. Holzman et al. in tens. Surf. Det. 23: 309 (1986), R. Bilbo et al. in Soap Cosm. Chem. Spec., Apr. 46 (1990) and P. Ellis et al. in Euro Cosm. 1, 14 (1994). Examples of suitable betaines are the carboxyalkylation products of secondary and in particular tertiary amines which follow the formula (VI)

These in turn can be obtained using the relevant preparative methods in organic chemistry. For this purpose, ethylene oxide, propylene oxide or a mixture thereof - in random or block distribution - is added to the corresponding fatty acids, this reaction being acid-catalyzed, but preferably in the presence of bases such as, for. B. sodium methylate or calcined hydrotalcite. If a degree of alkoxylation of 1 is desired, the intermediates can also be prepared by esterifying the fatty acids with an appropriate alkylene glycol. The sulfation of the fatty acid polyglycol esters can be carried out in a manner known per se using chlorosulfonic acid or preferably gaseous sulfur trioxide, the molar ratio between fatty acid polyglycol esters and sulfating agent being in the range from 1: 0.95 to 1: 1.2, preferably 1: 1 to 1 : 1, 1 and the reaction temperature can be 30 to 80 and preferably 50 to 60 ° C. It is also possible to undersulfate the fatty acid polyglycol esters, ie to use significantly fewer sulfating agents than would be stoichiometrically required for complete conversion. For example, if one chooses molar amounts of fatty acid polyglycol ester to sulfating agent from 1: 0.5 to 1: 0.95 who receive the mixtures of fatty acid polyglycol ester sulfates and fatty acid polyglycol esters, which are also advantageous for a whole range of applications. In order to avoid hydrolysis, it is very important to carry out the neutralization at a pH in the range from 5 to 9, preferably 7 to 8.
