Abstract
Compositions are disclosed for protecting keratin-containing substances in the body, e.g. skin, nails and especially hair, from damage and for helping to restore the damaged keratinous material to a healthy state. In one embodiment the compositions will comprise a liquid fatty acid vehicle containing at least a long chain alkane for bonding hydrophobically to keratin.
Claims25
A prophylatic composition for permeating within keratinous body material to treat the keratinous material internally to protect and/or to restore it to a healthy state, the composition comprising effective amounts of the following ingredients:
- (1) from about 10.00 to about 83.60 percent by weight of an oleophilic vehicle for permeating within the keratinous body material;
- (2) from about 1.75 to about 30.00 percent by weight of reagent which when transported within the keratinous body material in the oleophilic vehicle will bond hydrophobically to the keratin in the keratinous body material, the reagent comprising at least one n-alkane compound having at least eighteen carbon atoms;
- (3) from about 1.65 to about 6.70 percent by weight of long chain aliphatic compound of at least eight carbon atoms having hydrogen bonding or crosslinking sites at both ends;
- (4) from about 0.00 to about 26.40 percent by weight of SD alcohol;
- and
- (5) from about 0.00 to about 86.50 percent by weight of SD isopropanol.
A composition 2 wherein the aliphatic compound having hydrogen bonding or crosslinking sites at both ends is an alpha, omega-dibasic acid.
A composition as defined in claim 24 wherein the dibasic acid is sebacic acid.
A composition for permeating keratinous body material to treat the keratinous material internally, comprising an effective amount of oleophilic vehicle for permeating the keratinous body material, the vehicle containing an effective amount of reagent for bonding hydrophobically to keratin.
A composition for permeating keratinous body material to treat the keratinous material internally, comprising an effective amount of an oleophilic vehicle for permeating the keratinous material, the olephilic vehicle consisting of at least one free fatty acid which occurs naturally in the keratinous body material, the olephilic vehicle containing an effective amount of reagent which when transported within the keratinous body material will bond hydrophobically to the keratin in the keratinous body material, the reagent consisting of at least one n-alkane having at least eighteen carbon atoms.
The method for treating hair on a human's head comprising the steps of:
- applying to the hair a composition comprising an effective amount of an oleophilic vehicle for permeating within the hair, the vehicle containing an effective amount of reagent for bonding hydrophobically to keratin;
- allowing the composition to diffuse into the hair and scalp;
- and
- thereafter removing excess composition which has not diffused into the hair and scalp.
