Benefits of technology

[0119] The above conditioner is particularly effective when applied to hair as a post-wash treatment for the repair and prevention of damage.

Problems solved by technology

Hair can suffer damage from a number of sources.
The hair fibre can be damaged by environmental influences such as exposure to UV and chlorine; chemical influences such as bleaching, perming, overfrequent washing with harsh surfactant based cleansing shampoo compositions; and mechanical influences such as prolonged use of heated styling appliances.
Damage to the hair typically manifests itself in cuticle and protein loss from the hair fibre, excessive fibre stiffness, hair fibre brittleness and breakage and frayed or split ends.

example 1

Preparation of a Dispersion of Multilamellar Vesicles Containing L-Arginine, Cholesterol and Oleic Acid

[0110] Step 1: Add L-Arginine to hot water at 80 degrees C.

[0111] Step 2: Mix Cholesterol and Oleic Acid in 1:1 ratio

[0112] Step 3: Add mixture of cholesterol and oleic acid to L-arginine solution and mix until dispersed completely (about 30 minutes.

[0113] (At this stage, multilamellar vesicles can be observed by polarised optical microscopy)

[0114] Step 4: Add 1:1 mixture of polyoxyethylene (4.2) lauryl ether and polyoxyethylene (25) lauryl ether to stabilise vesicles

[0115] Step 5: Adjust pH to 6-7 with citric acid

example 2

[0116] The dispersion obtained from Example 1 above may be blended with shampoo ingredients to form a shampoo composition having the following composition:

1 Component % by weight Sodium lauryl ether 9.02 sulphate 2EO (70% a.i.) Pearlised sodium lauryl ether 13.00 sulphate 2EO (13.8% a.i.) Cocamidopropyl betaine (30% a.i.) 13.34 JAGUAR C13S 0.30 Dimethicone emulsion 10.sup.6 cs (60% a.i.) 2.5 Dimethicone emulsion 10.sup.5 cs (40% a.i.) 3.75 Oleic acid 0.025 L-Arginine 0.2 Cholesterol 0.025 Polyoxyethylene (4.2) lauryl ether 0.0025 Polyoxyethylene (25) lauryl ether 0.0025 Citric acid 0.165 Preservative, colour, fragrance q.s. Water, minors to 100%

[0117] The above shampoo is particularly effective when applied to hair for the repair and prevention of damage.

example 3

[0118] The dispersion obtained from Example 1 above may be blended with conditioner ingredients to form a conditioner having the following composition:

2 Component % by weight Cetyl trimethylammonium 4.0 chloride (25% a.i.) Cetostearyl alcohol 1.21 Paraffin wax 1.0 Silicone emulsion.sup.(1) 3.33 Oleic acid 0.025 L-Arginine 0.2 Cholesterol 0.025 Polyoxyethylene (4.2) lauryl ether 0.0025 Polyoxyethylene (25) lauryl ether 0.0025 Citric acid 0.072 Hydroxyethylcellulose 0.35 Preservative, colour, fragrance q.s. Water, minors to 100% .sup.(1)Added as 60% a.i. emulsion of 13 Mcs dimethicone gum, 200 cs dimethicone fluid and amino functional silicone, in a nonionic surfactant base, of silicone particle size 5 microns.

[0119] The above conditioner is particularly effective when applied to hair as a post-wash treatment for the repair and prevention of damage.

Abstract

The invention provides a hair treatment composition such as a shampoo or conditioner suitable for topical application to hair for the repair and prevention of damage, comprising (i) cholesterol, and (ii) a hair benefit agent which is a mixture of a basic amino acid and a fatty acid. Preferably the cholesterol and hair benefit agent are compounded into a dispersion of multilamellar vesicles, stabilized with nonionic surfactant.

Description

[0001] The invention relates to hair treatment compositions. More particularly the invention relates to hair treatment compositions comprising cholesterol in combination with certain hair benefit agents, which compositions are particularly suitable for application to hair for repair and restoration of damaged hair, and for moisturisation and protection of the hair fibre against future damage.BACKGROUND AND PRIOR ART[0002] Hair can suffer damage from a number of sources. The hair fibre can be damaged by environmental influences such as exposure to UV and chlorine; chemical influences such as bleaching, perming, overfrequent washing with harsh surfactant based cleansing shampoo compositions; and mechanical influences such as prolonged use of heated styling appliances.[0003] Damage to the hair typically manifests itself in cuticle and protein loss from the hair fibre, excessive fibre stiffness, hair fibre brittleness and breakage and frayed or split ends.[0004] A wide array of ingredie...
