Embodiment

[0060] The following examples are included to illustrate embodiments of the invention. It should be appreciated by those of skill in the art that the procedures disclosed in the examples which follow represent approaches discovered by the inventors to function well in the practice of the invention, and thus can be considered to constitute preferred modes for its practice. However, those of skill in the art should, in light of the teachings provided herein, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention. All percentages are in wt.%. Stability was determined at weekly and monthly intervals for up to 12 months at 25°C using a Brookfield ammeter. Stability is defined as a constant viscosity over time.

[0061] Examples 1 to 3 - Emulsions 1 to 3

[0062] Emulsion 1 contains: 50% mixture of cyclopentasiloxane and dimethiconol, stabilize...

Embodiment 4 to 7

[0066] Gel compositions comprising Emulsions 1 and 2 were prepared as listed in Table 1 . Examples 4 and 5 are stable at room temperature for at least 12 months, and Examples 6 and 7 have reduced viscosity after 12 months at room temperature.

[0067] Process for preparing the gel compositions of Table 1:

[0068] - Mix thickener and water until homogeneous

[0069] -Add emulsion and continue mixing until completely homogeneous

[0070] Table 1

[0071]

Embodiment 8 and 9

[0073] The oil-in-water cream compositions were prepared as described in Table 2. The composition is homogeneous and stable at room temperature for at least 12 months.

[0074] Procedure for preparing the O / W compositions of Table 2:

[0075] -Mix the ingredients of Phase A until homogeneous

[0076] -Mix the ingredients of Phase B together and add Phase A while mixing

[0077] - Add phase C and mix until homogeneous

[0078] Table 2

Abstract

The present invention relates to home and personal care compositions comprising a silicone oil-in-water emulsion stabilized by a protein or peptide and at least one home and / or personal care ingredient. Such compositions tend to provide desirable characteristics for the care and conditioning of hair, skin and fabric.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from GB patent application 0822823.1 filed 15 December 2008, the disclosure of which is incorporated herein by reference. Background of the invention [0003] The present invention relates to home and personal care compositions comprising silicone oil-in-water emulsions comprising droplets of silicone oil dispersed in a continuous aqueous phase. Silicones (organopolysiloxanes) are present in many hair care products to enhance the luster and healthy appearance of the hair, and also in skin care products to enhance the smooth feel of the skin. Silicones are also present in laundry products such as rinse cycle fabric softeners to provide a soft feel to fabrics. [0004] An increasing number of end users suffer from allergies and therefore there is a need for products which do not contain potentially irritating and possibly sensitizing molecules as surfactants. This is especially true for p...
