본 발명은, (i) 제1 발포 재료(effervescent material), 및 (ii) 알긴산 염을 함유하는 제2 발포 재료를 포함하는 고형 화장품(solid cosmetic product)을 제공하고, 각각의 발포 재료는 물과 접촉시 발포할 수 있고, 제1 발포 재료의 발포 속도(rate of effervescence)는 제2 발포 재료의 발포 속도보다 크며, 제1 및 제2 발포 재료는 서로 다르고, 제2 발포 재료는 제1 발포 재료를 감싼다. 본 발명은, (a) 탄산 염(salt of carbonic acid); (b) 유기 산성화제(organic acidifying agent); (c) 알긴산 염(salt of alginic acid); 및 (d) 칼슘 염을 포함하는 고형 화장품을 또한 제공한다. A solid cosmetic product comprising a first effervescent material and a second effervescent material, the second effervescent material containing a salt of alginic acid, wherein each effervescent material is capable of effervescence on contact with water, wherein the rate of effervescence of the first effervescent material is greater than the rate of effervescence of the second effervescent material, and wherein the first and second effervescent materials are distinct from each other, and wherein the second effervescent material envelops the first effervescent material. Each effervescent material may comprise a salt of carbonic acid, such as sodium bicarbonate, sodium carbonate and/or sodium sesquicarbonate, and an organic acidifying agent, such as tartaric acid, cream of tartar and/or citric acid. The salt of alginic acid may be selected from sodium alginate, potassium alginate and calcium alginate. The composition may comprise a calcium salt such as calcium lactate, calcium chloride, calcium gluconate or calcium lactate gluconate. The composition may comprise a third effervescent material. A solid cosmetic product comprising: a salt of carbonic acid; an organic acidifying agent; a salt of alginic acid; and a calcium salt.
