The present invention relates to compositions which can be used for preparing structured formulations, to structured formulations comprising these compositions, and to processes for preparing structured formulations.
Structured surfactant-containing formulations are liquid crystalline compositions in which the surfactants are present in the form of planar and/or spherolithic lamellar phases. Usually, the surfactant phases are present in dispersed form as spheroliths, i.e., as lamellar droplets in the aqueous phase. Such spheroliths consist of an onion-like configuration of concentric double layers of surfactant molecules between which water or electrolyte solution is trapped. Structured surfactant compositions are typically pumpable, non-Newton compositions which are able to suspend water-insoluble particles, such as, for example, oil droplets, on account of the presence of these lamellar surfactant phases.
Such structured formulations are used, for example, in cosmetic cleansing formulations such as shampoo, shower gel, soap, face cleanser, foam bath and body care formulations such as lotions, creams, conditioners, shaving products and baby care formulations.
An excellent property of such structured formulations is their ability to efficiently deposition substances present therein on a surface upon the addition of water.
WO 2008118381 discloses structured surface-active compositions comprising, based on 100 parts by weight of the composition,
A disadvantage of the formulations described in the prior art is that the prior art formulations do not have a particularly good foaming behaviour.
The necessary content of alkyl ether sulfates in the formulations of the prior art is likewise disadvantageous.
A further disadvantage of the structured formulations of the prior art is that the ratio of surfactants to contained oils is high.
In view of the above, there is a need to provide readily foaming, structured formulations with a high oil fraction, such as, for example, 20-60% by weight, based on the total formulation.
Surprisingly, Applicant has found that with the help of a composition comprising at least one esterification product of at least one polyhydric alcohol and at least one fatty acid, it is possible to prepare readily foaming, structured formulations with a high oil fraction. Since esterification products of a polyhydric alcohol and of a fatty acid are not known as readily foaming surfactants, and in particular, formulations with a high oil content, which comprise, for example, more than 10% by weight of oil, normally exhibit low foam in cosmetic applications, the present invention is very surprising.
The present invention therefore provides compositions comprising:
The present invention further provides structured formulations comprising the compositions according to the invention.
The present invention yet further provides processes for preparing the structured formulations according to the invention.
One advantage of the present invention is that large amounts of oil can be incorporated into the formulations according to the invention.
It is a further advantage of the present invention that the formulations according to the invention can be made sulfate-free, in particular ether-sulfate-free.
An even further advantage of the present invention is that the formulations according to the invention can be made polyether-free.
A yet further advantage of the present invention is that the formulations according to the invention can stably comprise a very large amount of oil, based on the amount of surfactant present.
It is a further advantage that the formulations can be formulated very mild with regard to skin and eye irritation potential.
It is a further advantage of the present invention that the formulations according to the invention are storage-stable, both at elevated and reduced temperatures, as well as up on temperature fluctuations.
A further advantage of the present invention is that the formulations according to the invention can stably comprise fragrances, active ingredients and care substances and are able to deposition these to a high degree. This has the advantage that, for example, the fragrance is spread evenly on the surface and is released over a prolonged period.
It is a further advantage of the present invention that the formulations according to the invention can be prepared in part cold and/or without the input of a large amount of energy.
A yet further advantage of the present invention is that the formulations according to the invention can be formulated without fatty acids and fatty alcohols.
A further advantage of the present invention is that the formulations according to the invention can have a yield point without the addition of polymeric rheological additives.
A further advantage of the present invention is that the formulations according to the invention are high-foaming despite the high fraction of oil.
A further advantage of the present invention is that the formulations according to the invention can be readily rinsed off.
A yet further advantage of the present invention is that the skin feel is improved during and after washing.
A further advantage of the present invention is the improved resistance to washing of oxidative hair colours.
A further advantage of the present invention is that the formulations according to the invention lead, upon application to the hair, to improved shine and to improved conditioning of the hair.
A yet further advantage of the present invention is the special creamy and rich texture of the formulations which can be obtained. Moreover, this texture can be attained without adding relatively large amounts of salt.
A further advantage of the present invention is that the formulations according to the invention can be formulated free from dialkylsulfosuccinate.
A further advantage of the present invention is that the contained esterification products of a polyhydric alcohol and of a fatty acid, which constitute the majority of the raw materials, are present as liquid substances with an active content of more than 95% by weight.

The liquid, colourless product was not worked up further.
SITA R-2000 Foam Tester:
To evaluate the foam properties and in particular the foamability, tests were carried out with the Sita foam tester (SITA R-2000 Foam Tester, SITA Messtechnik GmbH, Germany). For this, formulations according to the invention were compared to a market product, namely the comparative example “DG Deeply Moisturizing Body Wash” (PA) according to the prior art. The “DG Deeply Moisturizing Body Wash” includes a structured composition according to WO 2008118381.
Processing was carried out at T=30° C., with water of hardness 10° dH (German hardness), at a pH˜6 and with a rotational speed of 1500 rpm.
The table contains the foam heights (in ml) after different times (10-100 sec) of formulations according to the invention which all comprise 3% Sodium Laureth Sulfate, 3% Cocamidopropyl Betaine, 1% Cocamide MEA and 50% sunflower oil and different esterification product of a polyhydric alcohol and a fatty acid.
The results show firstly that the foam heights of the compositions according to the invention are significantly superior to those according to the prior art.
To evaluate the foam properties and the skin care performance of the formulations according to the invention, a sensory handwashing test was carried out compared to a market product, namely the comparative example “DG Deeply Moisturizing Body Wash” (PA) according to the prior art. The “DG Deeply Moisturizing Body Wash” includes a structured composition according to WO 2008118381.
