PURPOSE: A cosmetic composition which includes weight regulator is provided to solubilize or emulsify the oil and water layers and improve the product stability when a small amount or no surfactant is available. CONSTITUTION: A cosmetic composition which includes weight regulator has oil and water layers including weight regulator to be solubilized as well as emulsified and includes less than 0.5 weight% of the total weight composition included/not included a surfactant. The surfactant includes less than 0.1 weight% of the total weight of the composition. The difference between the weight of the oil layer including the weight regulator and weight of the final composition has no difference or is less than 0.02. The weight regulator has a weight over 0.990 at 20 °；C. The weight regulator comprises the following content: 1.0 = (rate of the weight regulator X rate of the weight regulator among oil layer) + (weight of other oily component X rate of other oily component among oil layer).본 발명은 비중조절 화장료 조성물에 관한 것으로, 비중조절제를 함유하여 계면활성제가 없거나 소량 함유하여도 제형안정성을 향상시킬 수 있으며 계면활성제로 인한 피부 문제점을 감소할 수 있어 피부 안전성을 높일 수 있다는 장점이 있다.
