Sunscreen lotion for pregnant and lying-in women and people with sensitive skin and preparation method thereof

Abstract

The invention relates to a sunscreen lotion for pregnant and lying-in women and people with sensitive skin. The sunscreen lotion is prepared from the following components in parts by weight: a A-phasecomponent, a B-phase component, a C-phase component and a D-phase component, wherein the A-phase component is prepared from C12-20 alkyl glucoside, C14-22 alcohol, homosalate, octocrilene, cetearyl alcohol and bisabolol; the B-phase component is prepared from water, xanthan gum, potassium cetyl phosphate, 1, 3-butanediol and titanium dioxide; the C-phase component is composed of water and an acrylic acid (acrylate) copolymer; the phase-D component is prepared from water, 1, 3-butanediol, an aloe leaf yucca leaf / root extract, a cactus extract, p-hydroxyacetophenone, ethylhexylglycerin, 1, 2-pentanediol, 1, 2-hexanediol, lavender flower oil and Anthemis nobilis L. oil. The invention also discloses a preparation method thereof. The invention has the advantages that the sunscreen lotion doesnot contain irritant chemical sun-screening agent components, adopts mild and non-irritant chemical sun-screening agents and physical sun-screening agents and an additive-free preservative safe formula, and is specially customized for pregnant and lying-in women and people with sensitive skin to achieve high sun-screening value and high PA value.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen for pregnant women and people with sensitive skin and a preparation method thereof.

Problems solved by technology

Chemical sunscreens have the advantages of broad ultraviolet absorption spectrum and high absorption intensity, which make them have a significant sunscreen effect. However, under the action of light, commonly used chemical sunscreens will decompose and produce free radicals or intermediate products that are harmful to the human body. Long-term use will cause damage to the skin and even the human body, such as MCX, ethylhexyl methoxycinnamate, benzophenone-3, benzophenone-4, etc.

However, physical sunscreens only reduce UV energy through optical reflection or scattering, and cannot achieve comprehensive and efficient UV protection performance when used alone
