Product Introduction

1.3-Dihydroxyacetone is also called Dihydroxyacetone which is a white crystalline powder. In cosmetics and personal care products, Dihydroxyacetone is used in the formulation of self-tanning products. Dihydroxyacetone imparts a color to the human body. It also enhances the appearance of dry or damaged skin by reducing flaking and restoring suppleness.

Dihydroxyacetone, is a color additive used in self-tanning or sunless tanning products. It darkens the skin by reacting with amino acids in the skin’s surface. It works by reacting with the amino acids present on the top layer of the skin to form shades of brown depending on the usage. It is commonly found in products like sprays, lotions, and mousses that target tanning.
Dihydroxyacetone powder is used as a major ingredient in most sunless tanning products. It can be used alone for the desired effect or combined with other tanning additives such as Erythrulose for a more specific effect. Dihydroxyacetone is often used as a formula raw material for cosmetics, which can play the role of sunscreen, moisturizing, preventing ultraviolet rays from invading the skin, etc., and can make people’s skin produce an artificial brown color.

1,3-Dihydroxyacetone is primarily synthesized through the chemical reaction of glycerol with ketone-containing compounds, such as acetone or chloral hydrate, under alkaline conditions. This reaction results in the formation of Dihydroxyacetone, a three-carbon sugar, which is then purified through processes like distillation or crystallization. Dihydroxyacetone is considered safe for topical use in cosmetic products when used as directed. It does not penetrate beyond the outermost layer of the skin, making systemic absorption unlikely. However, allergic reactions or skin irritation may occur in sensitive individuals, particularly those with respiratory conditions or compromised skin barriers. Inhalation of Dihydroxyacetone mist during spray tanning should be avoided. While DHA provides a sunless tan, it does not protect against UV radiation, so sunscreen should still be used to prevent sun damage.

1,3-Dihydroxyacetone finds widespread use primarily in the cosmetic industry, notably in sunless tanning products such as self-tanners, bronzers, and spray tans. When applied topically, this ingredient reacts with amino acids in the skin's outermost layer, resulting in a temporary brown coloration that simulates a natural tan without exposure to harmful UV radiation. Its application is convenient and provides an even tan appearance, making it popular for achieving a sun-kissed look year-round. Additionally, Dihydroxyacetone is used in the formulation of skin care products to impart a subtle tint, providing a healthy glow and enhancing the complexion without the need for sun exposure.
