For the past five years, one of the three most used claim for shampoos, hair treatments and conditioners is hair shine. Whatever the hair type, ethnicity, culture and region, consumers are all looking for shinier hair; a synonym of healthy hair. 


The new emollient and the new vegetable emollient are proven to bring shine to hair. The test consists of only one application of classical rinse-off conditioner formulas containing only 1% of the new emollient V21, the new vegetable emollient L15 or phenyl trimethicone (hair shine reference). Both the new emollient and the new vegetable emollient deliver significant hair shine in comparison with the untreated hair tress, however phenyl trimethicone does not significantly increase hair shine. 


If shine is the first sign of healthy hair, hair suppleness and manageability could be the next criteria. During an evaluation performed by three hairdressers on fifteen volunteers, the new emollient V21 (2%) demonstrated its ability to replace 2% silicone oil (dimethicone) in a rinse-off formula. The the new emollient V21 formula was selected by the professionals as their favorite product; the one they would prefer to use in their hair salon. The new emollient V21 shows similar results to dimethicone in terms of performance and sensoriality. The hairdressers found the formula containing the new emollient V21 as easy to apply and rinse as the one with dimethicone. The ease of combing was also facilitated with both formulas.


More important is the sensory part. Dimethicone is well known for the gliding sensation it brings to wet hair but also the softness, shine, and suppleness it gives to hair after drying. The professionals evaluated the new emollient V21 to be as good as dimethicone in improving hair appearance and touch. 


Wet combing was also tested with an in vitro method (using the Diastron MTT device) and showed that the tested oils (the new emollient V21, the new vegetable emollient L15, dimethicone 350cps and mineral oil) all decrease by approximately 90% the required combing force. This test was done on damaged Caucasian hair tresses, treated with a rinse-off formula containing 2% of oil.
