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.

A feminine hygiene system contains one or more feminine hygiene products that establish, restore, or maintain an optimal vaginal microbiome, an optimal interior environment of the vagina, and healthy vaginal tissue, including ion concentrations and ratios in vaginal secretions. A method using the feminine hygiene system establishes, restores, or maintains an optimal vaginal microbiome, an optimal interior environment of the vagina, and healthy vaginal tissue, and alleviates vaginal discomfort or symptoms arising from medical or physiological causes.

Disclosed are stable, non-irritating, skin treatment active agents containing formulations and delivery systems for topical application to the skin.

The present invention relates to a cosmetic skin lightening composition comprising the combination of sclareolide, kojic acid and ascorbyl glucoside, wherein kojic acid is encapsulated within a targeted microcapsule or nanocapsule having a melanocortin 1 receptor (MC1R) agonist peptide bound to the surface. It was found that such combination of active substances provided synergistic kin-whitening effect. The present invention also relates to the cosmetic use of this composition for skin whitening, particularly, for the elimination or reduction of hyperpigmented marks of the skin, such as UV exposure related marks, post-scar marks, post-inflammation marks, melasma marks, lentigo marks or age-related marks.

The present invention relates to a cosmetic composition comprising a) one or more polyhydroxyalkanoate (PHA) copolymers which contain, and preferably consist of, at least two different repeating polymer units chosen from the units (A) and (B) below, and also the optical or geometrical isomers thereof, the organic or mineral acid or base salts thereof, and the solvates thereof such as hydrates: -[-0-CH(R.sup.1)—CH.sub.2—C(0)-]- unit (A) -[-0-CH(R.sup.2)—CH.sub.2—C(0)-]- unit (B) in which polymer units (A) and (B): —R.sup.1 represents a hydrocarbon-based chain chosen from i) linear or branched (C.sub.5-C.sub.28)alkyl, ii) linear or branched (C.sub.6-C.sub.28)alkenyl, iii) linear or branched (C.sub.6-C.sub.28)alkynyl; preferably, the hydrocarbon-based group is linear; said hydrocarbon-based chain being optionally substituted and/or interrupted with atoms or groups as described in the description; —R.sup.2 represents a cyclic or non-cyclic, linear or branched, saturated or unsaturated hydrocarbon-based group, comprising from 3 to 30 carbon atoms; and b) one or more surfactants; it being understood that (A) is different from (B).

A water-in-oil emulsion cosmetic, in which an ultraviolet scattering agent is uniformly dispersed in a base, an excellent ultraviolet protective effect is stably imparted, and whitishness is suppressed. A water-in-oil emulsion cosmetic is described, comprising the following components (a), (b), (c), and (d): (a) titanium dioxide surface-treated with a fatty acid and/or an alkylalkoxysilane; (b) an amphiphilic substance which is solid at normal temperature; (c) a linear silicone oil; and (d) a volatile hydrocarbon oil.
