The present disclosure relates to hair care compositions such as hair treatment compositions and hair lightening compositions, methods for treating hair (e.g., lightening hair), and to kits comprising the compositions. The components of the hair treatment compositions may be included in hair lightening compositions and used to lighten and/or color hair. The hair treatment compositions typically include: (a) one or more polycarboxylic acids, and/or a salt thereof; (b) one or more amino acids, and/or a salt thereof; and optionally (c) one or more cationic conditioning agents. The hair lightening compositions further include (d) one or more bleaching agents.

Compositions and devices are described that provide controlled release of beneficial bacteria to the oral cavity. Such bacteria can subsequently colonize the oral cavity and displace or suppress the growth of pathogenic microorganisms. Described devices include a stabilized preparation of such beneficial bacteria and provide a consumable liquid, wet foam, or gel that includes such bacteria when used.

Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water.

Aspects of the present invention relate to an improved antimicrobial and/or anti-viral composition comprising an antimicrobial and/or anti viral mixture consisting of: H.sub.2O.sub.2 at a final concentration of between 3-7% v/v, and a poloxamer at a concentration of 0.1-10% w/v. The poloxamer is in a composite hydrogel formulation. The composition disclosed herein is antimicrobial and/or anti-viral and is particularly useful for cleaning, sterilizing, disinfecting, sanitizing, decontaminating and/or debriding biological surfaces and surfaces of biomaterials, such as when provided in a hand sanitizer, mouth wash, nasal rinse and/or for wound care and/or chronic ulcer care and use for dental prophylaxis and peri-implant health maintenance.

Disclosed herein are oral care compositions comprising a peroxide whitening complex in an amount to provide from 3.5% to 7% of hydrogen peroxide by weight of the composition, and a block copolymer of ethylene oxide and propylene oxide in an amount of from 40% to 60% by weight of the composition. Methods of making and using the dentifrices are also provided.

A toothpaste composition includes a structurant and a thickener, wherein the toothpaste composition has a predetermined viscosity and phase angle by using the structurant instead of reducing the content of a thickener, and thereby has an improved release property during use while maintaining a shape retention property of the toothpaste, and has an improved feeling of refreshment, flavor releasing power, cleaning power, and stain removal power. Further, provided is a toothpaste composition including a chelating agent containing phosphate and silica, wherein the chelating agent is supersaturated to precipitate phosphate to provide strong cleaning power, a whitening effect, a stain removal effect, and a crunchy sensation. Further, provided is a toothpaste composition including a peroxide, a thickener, and a spreading agent, wherein the peroxide and the thickener are separated from each other, providing excellent sense of use, stability, and a whitening effect in an anhydrous state.
