BACKGROUND

Skin can be compromised or irritated as a result of various factors, e.g. harsh climate, low hydration level, and so forth. As such, there is a need for products which do not further irritate or compromise the skin; and that promote skin cell viability and/or skin barrier repair.

Taurine, or 2-aminoethylsulphonic acid, is a non-proteinogenic amino acid that is known to have skin health benefits. For instance, taurine is known to exhibit antioxidant properties, regulate inflammatory reactions and enhance skin barrier repair. Taurine has been incorporated in various forms of personal care products and its skin health benefits have been documented both on lab skin models and clinical evaluations.

However, taurine shows stability issues in some formulations, such as bar soap. In particular, taurine tends to recrystallize on the surface of bar soap after aging. The recrystallized taurine can cause an undesirable look and/or feel to the bar soap product.

Taurine based surfactants, such as sodium methyl oleoyl taurate and sodium methyl cocoyl taurate, are known to be mild and high-foaming surfactants. They have been employed in certain personal care products. However, the taurine moiety of these surfactants is covalently bonded to a fatty acid group that does not dissociate in solution to provide for availability of free taurine. Because the taurine moiety is tied up in solution with the fatty acid group, one of ordinary skill in the art would not expect the taurate surfactants to have the above described skin health benefits associated with taurine.

While compounds such as taurine are known for improving skin health, discovering additional compounds that have skin health benefits and that are otherwise compatible with personal care and home care products would be a welcome advancement in the art.

BRIEF SUMMARY

An embodiment of the present disclosure is directed to a bar soap composition. The composition is made from ingredients comprising: at least one cleanser chosen from soap and a first surfactant; and at least one taurate surfactant chosen from a salt of a fatty acid amide of taurine, a salt of a fatty acid amide of N-methyl taurine, and combinations thereof. The taurate surfactant is different than the first surfactant. The composition is in a solid bar form.

Another embodiment of the present disclosure is directed to a composition made from ingredients comprising at least one taurate surfactant chosen from a salt of a fatty acid amide of taurine, a salt of a fatty acid amide of N-methyl taurine, and combinations thereof. The composition is in the form of a personal care product or home care product. If the composition is a personal care product in the form of a shampoo, the composition 1) does not include more than 0.1% of a mono ester anionic surfactant and does not include more than 0.1% of an amphoteric amide surfactant, 2) does not include more than 0.01 weight % of silicone Quaternium-8, and 3) is either (i) not both a shampoo and a conditioner or (ii) comprises at least one of a sulfate based surfactant or a polydimethylsiloxane.

Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
