An improved hair treating or conditioning composition that decreases the friction between hairs thereby facilitating in combing and brushing of hair treated therewith contains a formulation which is a mixture of d-panthenyl ethyl ether and d-panthenol in a weight ratio of about 9 parts d-panthenol ethyl ester to about 1 part d-panthenol. Such hair treating or conditioning compositions also exhibit decreased damaged to hair treated therewith due at least in part to a decrease or reduction in abrasion between hairs. |

DETAILED DESCRIPTION OF THE INVENTION The formulation of 9 parts d-panthenyl ethyl ether and 1 part d-panthenol can be incorporated in hair conditioning or treating compositions in an amount generally of from about 0.
05% by weight to about 10% by weight of the composition.
Most preferably about 0.
1% to 0.
5% of the formulation is employed in the composition.
It is surprising that hair care compositions containing the 9/1 formulation of this invention do not induce a large increase in friction immediately (within two minutes) and do decrease hair abrasion after treatment with such compositions since hair treated with a similar hair composition commercially available but containing 3 parts by weight d-panthenyl ethyl ether to every seven parts by weight d-panthenol exhibits both a significantly large increase in hair friction immediately after treatment and increases rather than decreases hair abrasion damage.
The formulation of this invention can be incorporated into any suitable hair conditioning or treating compositions of non washout product form such as lotions, creams, solutions, gels, sprays and the like, but preferably in lotion compositions.
The hair composition can contain other ingredients normally or customarily found in such compositions such as antibacterial agents, emulsifiers, dye, colorants, perfumes and the like.
Also, the formulation may be incorporated into hair washing preparations such as shampoos, hair and scalp conditioners and the like.
The novel formulation of this invention can be prepared by simply mixing 9 parts by weight d-panthenyl ethyl ether with one part by weight of d-panthenol.
d-Panthenol is (R)-2,4-dihydroxy-N-(3-hydroxypropyl)-3,3-dimethylbutamide.
Such formulations are then suitable for incorporation into any suitable hair care composition in an amount of from about 0.
05% by weight to about 1% by weight, preferably about 0.
1% to 0.
5% by weight.
The unexpected absence of large increases in hair friction immediately after use and decrease in hair abrasion after use of the hair care composition of this invention is illustrated by the following comparative tests
