Embodiment 1

[0265] Example 1: Composition T1 according to the invention, and comparative composition TA

[0266] Compositions T1 and TA were made using the following method:

[0267] • Add polymeric thickener to water and mix until fully dispersed.

[0268] • Hydrolyzed protein, trehalose, sodium sulfate, adipic acid, gluconolactone and other water soluble materials are then added to the mixture.

[0269] • In a separate container, blend fragrance and other oil soluble materials with solubilizer.

[0270] • This mixture is then added to the main batch and mixed until a clear solution is obtained.

[0271] • In a secondary container, add one or more dye components to the water and mix until completely dissolved. Add the resulting dye mixture to the main container and mix well.

[0272] • Finally, adjust the pH to between 3 and 4.5 with sodium hydroxide.

[0273] Compositions are shown in Table 1.

Embodiment 2

[0281] Example 2: Color Stability of Compositions T1 and TA

[0282] Compositions T1 and TA were stored at a range of temperatures (5°C, 25°C, 37°C and 45°C) for 4 weeks. During this time, it was noted that T1 remained clear and had no yellowing discoloration when compared to TA, which became increasingly cloudy and yellowing over time.

Abstract

A transparent cosmetic or personal care composition comprising: a) a polymeric thickener; b) a protein; c) an active material selected from the group consisting of disaccharides, lactones, inorganic salts, diacids, and mixtures thereof; d) a solubilizer; e) a pH regulator; f) a dye; g) water; wherein the solubilizer comprises a mixture of at least two components comprising at least one high HLB component with an HLB value of 10 to 20 and at least one low HLB component having an HLB value of 1 to less than 10, and wherein the dye comprises violet, blue, red or mixtures thereof.

Description

technical field [0001] The present invention relates to a clear cosmetic or personal care composition, a method of treating surfaces using said composition, and the use of additive materials such as proteins, actives and fragrances in clear cosmetic and personal care compositions to repair hair damage the use of. Background technique [0002] Cosmetic and personal care compositions are often required to possess a variety of visual and functional attributes. For example, shampoos and hair conditioning compositions often need to have properties other than their ability to cleanse and / or condition hair in order to appeal to consumers. [0003] Clear, transparent compositions are often visually desirable, but are difficult to formulate without causing undesirable effects such as clouding and discoloration when incorporating other benefit agents such as silicones. [0004] It is known that gel particles can be incorporated into hair treatment compositions. Our European patent ...
