Description
PEARLESCENT BASED CONCENTRATE FOR PERSONAL CARE PRODUCTS
The invention relates to pearlescent based concentrates comprising at least one al ylpolysaccharide, traditional pearlescent esters or acid and alkyl sulphates and to processes for the preparation thereof.
Personal care products such as handsoaps, bubble baths, shampoos and hair conditioners often include in their composition agents which impart a pleasant, pearl-like glossy appearance in order to enhance the appeal of such products to the consumer. The agents which impart this appearance are known as pearlescent based concentrates and generally comprise microscopic platelike crystals which remain dispersed in compositions to which they are added and reflect light in such a manner as to impart a pearl-like appearance.
Pearlescent based concentrates of the prior art have included finely divided natural substances or inorganic compounds such as mica, fish scale, bismuth oxychloride or the like. For example, Japanese patent application no. 90/134,825 (Priority Date; 24 May 1990) describes compositions for cosmetics having a pearly appearance, comprising glucose fatty acid esters and mica and/or mica Ti.
In recent years, the use of a fatty acid glycolic ester in pearlescent concentrates has been particularly favoured. In general such concentrates are produced by adding a fatty acid glycolic ester which is solid at room temperature to a composition such as shampoo or the like, followed by heating of the mixture to melt the fatty acid glycolic ester, and then by cooling to recrystallise it and thereby providing small crystals which impart a pearl-like gloss to the composition. In an alternative method of production, a pearling agent dispersion (such as a fatty acid glycolic ester dispersion, which is dissolved and cooled to recrystallise in advance) is mixed with a shampoo or the like at room temperature as described in Japanese Patent Application nos. 71021/81 and 216728/83.
Other known pearlescent based concentrates have comprised microcrystalline polyvalent metal salts of higher fatty acids or fatty acid glycolic esters such as those described in United States Patent 4,959,200 (Date of Patent; 25 September 1990).
Other commonly used pearlescent based concentrates have been prepared using ethylene glycol monostearate, ethylene glycol di-stearate, glycerol monostearate, glycerol di- stearate or a cetyl stearly alcohol or the like in conjunction with other similar esters. These pearlescent based concentrates of the prior art have also normally comprised ether sulphates, betaines, ethanolamide, amine based surfactants and the like which can be used as emulsifiers. United States Patent 5,017,305 (Date of Patent; 21 May 1991) describes a typical pearlescent concentrate in the form of a free-flowing dispersion comprising pearlescing esters, ether carboxylic acids and one or more monoethanolamides of C12 to C22 fatty acids.
One of the disadvantages of the pearlescent based concentrates of the prior art is that they often comprise chemicals which are potential skin sensitisers. Japanese Patent Application no. 21678/83 for example, discloses a pearling agent containing a salt of alkyl sulphate or a salt of polyoxyalkylene alkyl sulphate, a fatty acid dialkanolamide and water as solvents, and a fatty acid glycolic ester at a high concentration. Many factors influence the irritation effect of surfactants and the molecular structure of the surface active agent can be closely linked to its effect on adsorption, solubilization, penetration, swelling, denaturation and general irritation o human skin.
Generally, the order of increasing human skin irritatio of anionic surfactants commonly used in personal care products is in the following order: Ammonium Laureth Sulphate <Sodium Laureth Sulphate <Ammonium Lauryl Sulphate <Sodium Lauryl Sulphate.
Furthermore, some of the pearlescent based concentrates of the prior art have included surfactants which may contain toxic trace impurities which are suspected carcinogens including nitrosamine containing compounds such as diethanolamides. European Patent no. 221465 (22 October
1992) for example, relates to a process for the production of pearlescent pigment comprising ethanolamide.
In general, alkyl polyglucosides demonstrate very little tendency to scalp irritations.
It has now been found that low irritant pearlescent based concentrates containing biodegradable surfactants can be prepared using alkylpolysaccharides. Ultimate biodegradability was measured using OECD tests 301E and 301A,1981. Alkylpolysaccharides are particularly attractive for use in personal care products because they contain no toxic trace impurities and because they are derived from renewable resources such as coconut oil and wheat starch.
The current invention therefore provides a pearlescent based concentrate including: between 5 and 40% by weight of the composition of alkylpolysaccharide of formula
H-Gχ-OR1 where R is selected from the group comprising linear or branched C6 to C22 alkyl or alkenyl group where G is selected from the group comprising a C5 or C6 saccharide and x is from 1 to 10;

n is 2 or 3 and x is from 1 to 120.
The current invention further provides a pearlescent based concentrate including: H-Gχ-0R1 where R is selected from the group comprising linear or branched C6 to C22 alkyl or alkenyl group where G is selected from the group comprising a C5 or C6 saccharide and x is from 1 to 10; between 3 and 30% by weight of the composition of alkyl sulphate and/or alkyl ether sulphate; and between 5 to 20% by weight of pearlescing acid of formula R COOH where R is chosen from the group comprising C16 to C22 alkyl groups.
In a preferred embodiment the pearlescing esters or acid of the current invention is chosen from ethylene glycol monostearate, ethylene glycol disterate, stearic acid and mixtures thereof.

Method
Ethylene glycol monostearate, decylpolysaccharide, alkyl sulphate, water and sodium chloride were heated to 80°C with vigorous stirring. The solution was maintained at 80°C with stirring for further 30 minutes before being rapidly cooled to 65°C. Once the solution temperature reached 65°C the stirring rate was slowed and the solution cooled at a controlled rate of 10°C per hour until the temperature reached 40°C. The stirrer was then stopped and the pearlescent blend allowed to cool to room temperature.
EXAMPLE 2
A pearlescent based concentrate of the following composition was prepared by the method described below.
Component Com osition (% w/w)
Dodecylpolysaccharide (50% a.i.) Sodium lauryl sulphate (30% a.i.) TERIC 12A23
Ethylene glycol mono-stearate Sodium chloride Water
Method
Ethylene glycol mono-stearate, dodecylpolysaccharide, sodium lauryl sulphate, TERIC 12A23 water and sodium chloride were heated to 80°C with vigorous stirring. Once the solution had reached 80°C, the stirring rate was slowed and the solution cooled at a controlled rate of 10°C per hour until the solution temperature had dropped to 0°C. When the solution temperature had reached 40°C the stirrer was stopped
and the pearlescent based composition was allowed to cool to room temperature. (TERIC is a registered trade mark of ICI Australia Operations Proprietary Limited) .
