Reflective Composition

Abstract

The invention provides a cosmetic composition for providing a retro-reflective effect to incident light to a natural or artificial substrate such as hair, skin, nails, eyelashes and the like. The composition comprises retroreflective microparticles and a transparent coating composition and is substantially free of goniochromatic colouring agents.

Description

EXAMPLES

Retroreflective Test and Temporary Application to Substrate

[0111] All compositions set out in the Examples below were subjected to testing to demonstrate the retro-reflective effect. Each composition was applied to hair and human skin and photographed both with and without a flash. The compositions all demonstrated a retro-reflective effect when photographed with a flash and no such effect when photographed without the flash. The compositions were all removed from the substrate upon washing with commercially available shampoo for personal use after a maximum of 2 washes.

Example 1

[0112] A cosmetic composition according to the invention and as described in Table 2 below was applied to a black real hair wig. The wig was subjected to flash photography and a retro-reflective effect was observed as shown in FIG. 1A. Without the flash light, the wig appeared a natural colour under ambient light conditions as shown in FIG. 1B.

Example 2

Example 6—Emulsion and Conditioner

[0117] A cosmetic composition according to the invention in the form of an emulsion was prepared to the composition set out in Table 6 below. Phase A was prepared by adding CARBOPOL ULTREZ 21 to the water, allowing to hydrate and then adding AMP to neutralise until a clear gel formed. The mixture was then heated to 70° C. Phase B was prepared by combining the components in a beaker and heating to 70° C. until the waxes had melted. Phase B was then added to Phase A at 70° C. and homogenised at 4000 rpm and cooled to 40° C. The components of Phase C were then added to the Phase A/Phase B mixture and homogenised. The beads of Phase D were then added to the mixture with mixing. The final composition had a pH of 4 to 4.5.

[0118] The composition of Example 6 was applied to hair and provided excellent retro-reflective effect when subjected to flash photography, an even coating on the hair and feel due to the conditioner. The hair was subjected to a standard washing process employing a commercially available shampoo for personal use. The hair was substantially free from the composition after 2 washes.
